What is the answer of a cure for the common cold?

Treatment – There’s no cure for the common cold. Most cases of the common cold get better without treatment within 7 to 10 days. But a cough may last a few more days. The best thing you can do is take care of yourself while your body heals. Care tips include:

Rest. Drink plenty of liquids. Humidify the air. Use saline nasal rinses.

Antibiotics do not treat cold viruses. They are used to treat illnesses caused by bacteria.

Which hazardous compound helps to preserve crumbling books reading with location?

IELTS Reading Passage – Hazardous compound helps to preserve crumbling books – You should spend approximately 20 minutes on Questions 1-12, which are based on the Reading Passage below. Hazardous Compound Helps to Preserve Crumbling Books Librarians may be able to save millions of books from slowly crumbling with a new chemical process that uses a hazardous flammable compound, diethyl zinc (DEZ).

1. Chemists in the US have successfully completed an 18-month trial of the technique, which neutralises the acids in paper which cause books to decay.
2. The method was developed by the Dutch chemical giant, Akzo, in collaboration with the US Library of Congress.
3. It can treat 1,000 books at a time at a fraction of the cost of digitising.

The world’s libraries and archives are today stocked mainly with books that are destroying themselves because of a new way of making paper that was introduced over a hundred years ago. In this process, wood pulp became the main source of the cellulose from which paper was made, replacing the cotton or linen rags used previously.

1. Unfortunately, book publishers were unaware that the slightly acidic nature of wood pulp would eventually threaten their work.
2. The acid attacks the cellulose polymer of paper, breaking it down into shorter and shorter pieces until the paper’s structure collapses.
3. The only answer is to neutralise the acids in the paper by chemical means.

This has generally been done by unbinding the book, treating it page by page with a carbonate solution, and then rebinding it. The cost can be as much as £200 per volume. Akzo’s method can be done without taking the binding off the book. On the face of it, DEZ would seem the last chemical that should be brought in contact with paper.

1. This volatile liquid bursts into flames when it comes in contact with air.
2. However, it is not DEZ’S sensitivity to oxidation which is the key to its use as a preserving agent, but its ability to neutralise acids by forming zinc salts with them.
3. Because DEZ is volatile, it permeates the pores in paper.

When it meets an acid molecule, such as sulphuric acid, it reacts to form zinc sulphate and ethane gas. DEZ is such a strong base that it will react with any acid, including the weaker organic ones. It will also react with any residual water in the paper to form zinc oxide.

1. This is an added bonus for the book conservators, since it buffers the paper against future attack by acidic gases from the atmosphere, such as sulphur dioxide.
2. Not only will DEZ protect against acid attack, but it is also capable of neutralising alkalis, which threaten some kinds of paper, it can do this because zinc oxide is amphoteric – capable of reacting with either acids or alkalis.

The Akzo method treats books that are closed, yet protects every page. It adds about two per cent of zinc oxide to the weight of the book. Much of this is deposited near the edges of the pages, the parts which are most affected by the acid from readers’ fingers or environmental pollution.

The only risk in the Akzo process comes from the DEZ itself; this compound caused a fire at NASA’s Goddard Space Flight Center where earlier tests on the method were carried out. For the process, the books are gently heated under vacuum for a day to remove residual traces of moisture. The chamber is then flushed with dry nitrogen gas for five hours to remove the remaining air before DEZ is introduced at a low pressure into the gas stream.

DEZ is passed through for about eight hours. Unreacted DEZ is trapped out of the exit gases and recycled, while the ethane is burned off. When the process is complete, the chamber is purged with nitrogen to remove residual DEZ. The whole process takes about three days.

The cost per book is about £2, considerably less than the £40 for digitising. This work was originally funded by the US Library of Congress, which has over 10 million books now at risk. According to Dick Miller, Akzo’s director for book preservation, tests have shown that the method can deal with hundreds of books at a time.

A million books a year could be rescued by the new process, for which Akzo has been granted exclusive rights. The treated books should then survive for hundreds of years. Another national institution, the British Library, launched an adopt-a- book scheme to help it meet the costs of processing books.

The British Library has so far raised over £80,000. But if the traditional method were used, this would barely cover a twentieth of one per cent of the two million books the Library needs to treat. Edmund King of the British Library’s preservation service says that the Library has developed another method which coats the individual fibres of the paper with ethyl acrylate polymer, protecting the books not only against acid attack but actually making them stronger.

The British Library is now seeking an industrial partner to exploit its work.

What to do before an operation in hospital general reading?

READING PASSAGE – 1 – What to do Before an Operation in Hospital In the days leading up to your surgery, you’ll need to think about how you’ll get to the hospital and back again. You probably won’t be well enough to drive, so you may want to arrange transport or ask a friend or relative to help.

Make sure you give your family and friends plenty of notice about your operation, so that if necessary they can take time off work to be with you. Check your hospital’s policy on visiting times and let your family and friends know. When preparing your things for your stay, remember to bring your appointment card with you too.

General Reading IELTS Pre-operative assessment At some hospitals, you’ll be asked to attend a pre-operative assessment, which may be an appointment with a nurse or doctor, a telephone assessment or an email assessment. You’ll be asked questions about your health, your medical history and your home circumstances.

• If the assessment involves a visit to the hospital, some tests may be carried out, including a blood test.
• This assessment will usually happen one or more days before your operation.
• Make sure you know the results of any previous tests.
• You’ll be given clear information on: – if you need to stop eating and drinking in the hours before your operation (see below) – whether you should cease taking your usual medications before going into hospital – what to bring with you into hospital – whether you’ll need to stay in hospital overnight and, if so, for how long General Reading IELTS The importance of fasting If your doctor has instructed you to fast before the operation, it’s really important that you don’t eat or drink anything – this includes light snacks, sweets and water.

You need an empty stomach during surgery, so you don’t vomit while you’re under anaesthetic. Hygiene You’ll need to remove all make-up and nail polish before your operation, as the doctors will need to see your skin and nails to make sure your blood circulation is healthy.

Can you sweat out a cold?

Sweating may provide temporary relief from cold symptoms, but it won’t shorten the duration of your cold. Colds typically last 7–10 days. Sweating out a cold is the idea that using heat, exercise, or things that can make us sweat makes a cold go away faster.

Sweat, or perspiration, is water that’s released from sweat glands in your skin. It’s your body’s way of cooling down. When your body temperature rises, your nervous system sends a message to your sweat glands to secrete water onto your skin. When this water evaporates off of your skin, it causes a cooling effect.

Sweat is mostly made up of water. It also contains small amounts of other substances, such as electrolytes and vitamins. While some of the methods used to “sweat out a cold” may provide temporary symptom relief, they don’t shorten the time that you’re sick.

inhaling warm steamvisiting a sauna or steam room exercise

These activities may temporarily relieve nasal congestion because they help to loosen nasal mucus. However, it’s the exposure to warm, moist air or physical activity, not the actual sweat, that’s beneficial in this case. You may have heard that exposure to hot steam can help treat a cold.

1. But does hot steam, such as what’s found in a hot shower or steam room, actually help? A 2017 analysis of six trials found that being exposed to heated, humid air was neither harmful nor beneficial for people with the common cold.
2. Steam inhalation therapy may pose the risk of burning or scalding from steam or water that’s too hot.

There isn’t enough evidence to determine if a sauna can treat colds. If you do decide to visit a sauna, try to follow the safety tips below:

Limit your sauna time to about 15 or 20 minutes.Avoid food or drinks that can cause dehydration, such as alcohol, caffeine, or salty foods. You can lose up to a fair amount of sweat from just a short sauna.Rehydrate after your sauna by drinking two to four glasses of cool water.Cool down gradually after your sauna. Going directly from a hot sauna to a cold environment can put unnecessary stress on your body.If you feel unwell at any time during your sauna, leave and cool off. Do not use a sauna if you’re pregnant.

It’s fine to try to get a workout in if you have the common cold. Exercise can temporarily relieve cold symptoms such as nasal congestion. That said, you should always take into account how you’re feeling. If you’re feeling pretty bad, you should just take a day off.

Rest up! Your body needs to fight off the illness. Try to get between 8 and 10 hours of sleep each night.Stay hydrated. Not only does this help your body fight your infection, but it can also loosen mucus. Warm liquids such as tea or broth can help soothe a scratchy throat, Try to avoid items that can cause dehydration, such as caffeine, alcohol, and salty foods.Use over-the-counter (OTC) medications to help relieve symptoms. Decongestants, pain relievers, and expectorants can help keep your symptoms under control. Be sure to follow the correct dosing guidelines. Gargle with saltwater if you have a sore throat. This can help reduce pain and swelling.Use a humidifier, Dry air can make your symptoms worse. Adding some moisture to the air can help keep your nasal passages moist and relieve congestion.

You may have heard that it’s beneficial to “sweat out a cold.” While exposure to heated air or exercise may help temporarily relieve symptoms, there’s little evidence to suggest that they can help treat a cold. You’re best off fighting your cold by getting plenty of rest, staying hydrated, and taking OTC medications to relieve your symptoms. Your cold should resolve itself within 7 to 10 days.

Why is there still no cure for the common cold?

Why can’t we cure the common cold? – There is no cure for colds; there only is treatment of symptoms, which can last anywhere from two days to two weeks. “Rhinovirus mutates very quickly and comes in many varieties, and for this reason, doctors are unable to make a vaccine to fight off colds as we can for the flu,” says Dr.

Foxman. Antibiotics do not work against colds because they kill bacteria, not viruses, Dr. Foxman says, so there is no reason to use them for a cold. This is especially important to know at a time when overuse of antibiotics has become a major concern because of increased antibiotic resistance. Unnecessary use of antibiotics may also harm your individual health.

“There is a lot of research that shows when you take antibiotics, you may be wiping out good, health-promoting bacteria as well as the bad bacteria,” Dr. Foxman says. Relief for the common cold is found through resting, increasing intake of fluids, gargling with warm salt water and possibly taking over-the-counter cold medicines, such as decongestants or cough suppressants.

What is the Akzo method of book preserving?

The Akzo method treats books that are closed, yet protects every page. It adds about two per cent of zinc oxide to the weight of the book. Much of this is deposited near the edges of the pages, the parts which are most affected by the acid from readers’ fingers or environmental pollution.

How does shelving help to preserve and protect books?

By Mary Lynn Ritzenthaler – These much-loved books could use some attention. Shelve your books so that volumes of approximately the same size are together and can support one another. Despite the popularity and convenience of e-books, many people own treasured books of the old-fashioned kind—paper leaves protected by covers.

1. These books range from diaries, journals, and Bibles that contain genealogical entries to first editions of favorite authors and beautifully illustrated children’s stories.
2. Careful handling will help to preserve them.
3. Storage — Store books away from sources of heat and moisture.
4. Avoid attics and garages, where temperatures can get high and where there can be problems with water or high humidity.

These conditions cause paper to become brittle (think of old newspaper clippings). Moisture can also attract insects. Light can cause book covers to fade, especially the spines of books exposed to sunlight for years. Position bookcases so that sunlight does not fall on books you want to preserve.

1. Preservation-quality boxes for individual volumes will protect books from excess light exposure and keep pieces of damaged bindings together, such as detached or loose covers.
2. Shelving — Store small- to medium-sized books upright (vertically).
3. Shelve books of approximately the same size together so they will support one another; otherwise, volumes will become distorted and covers will lose their shape.

Store large volumes, such as atlases, flat (horizontally). This will keep the covers flat and the text from separating from the covers. Handling — Handle books gently to avoid separating covers and spine pieces from the binding. Do not “dog-ear” or turn down the corners of pages.

• That will leave a permanent crease in the paper, and the corner may break off if the paper is weak and brittle.
• Use a thin piece of paper or a length of ribbon as a bookmark.
• Do not use metal devices that clip over the tops of pages or anything thick since they can tear and distort paper.
• Food and drink can stain paper, and if liquid falls on manuscript ink (such as a diary entry) the ink can feather and bleed.

Such damage is permanent. Making Copies — Do not place books face down on a photocopier or scanner. This puts stress on tightly bound volumes, resulting in bindings breaking and pages separating. Face-up copying is safest, using either a hand-held camera or a face-up copier.

1. Do not force books to open flat to get the “best” copy.
2. Book cradles can support books at a safe angle to protect the bindings.
3. Book Repair — Do not attempt to repair books that are unique or that you wish to pass on to future generations.
4. Using tape to mend torn pages or to reattach loose or detached covers, while well intentioned, ultimately causes more damage.

Simply box a damaged book, store it flat, and handle the volume very carefully. For repairs or conservation treatment, check the free referral service from the American Institute for Conservation for a book conservator in your region (www.conservation-us.org/membership/find-a-conservator).

What chemicals are used in books?

Various chemicals such as sodium hydroxide and hydrogen peroxide are used to manufacture paper. As these cause reactions with the other chemicals in the paper, VOCs are released into the air.

What should I do 24 hours before surgery?

If you are having general anesthesia or sedation for your procedure: –

Take nothing by mouth after midnight the night before. This means that you cannot drink any liquids, eat food, chew gum, smoke a cigarette, or have a mint. If you brush your teeth, do not swallow any water. If your surgery is late in the day, please ask the nurse or anesthesiologist about having a light breakfast. You will be instructed by your doctor or pre-admission nurse which medications to take the morning of surgery. Take medication with a sip of water only.

These instructions are for your safety. Please follow the directions from the pre-admission nurse and the anesthesiologist prior to surgery to avoid possible cancellation.

What should you not do before general anesthesia?

Eating and drinking before a general anaesthetic – Usually, before having a general anaesthetic, you will not be allowed anything to eat or drink. This is because when the anaesthetic is used, your body’s reflexes are temporarily stopped. If your stomach has food and drink in it, there’s a risk of vomiting or bringing up food into your throat.

If this happens, the food could get into your lungs and affect your breathing, as well as causing damage to your lungs. The amount of time you have to go without food or drink (fast) before you have your operation will depend on the type of operation you’re having. However, it is usually at least 6 hours for food, and 2 hours for fluids.

You’ll be told how long you must not eat or drink for before your operation. Chewing gum, including nicotine gum, should be avoided during this fasting period. You may be told to avoid certain types of fluids, such as milk, or tea and coffee with milk added to them, before an operation.

Is it better to be hot or cold when sick?

Avoid Cold and Damp Environments – Although it’s a myth that you’ll get sick just from not bundling up when it’s cold outside, it’s true that bacteria and viruses thrive at cooler temperatures. So if you’re fighting a bug, it’s best to stay warm and dry.

What is the best exercise for a cold?

Story highlights – If your symptoms are above the neck, you’re safe to break a sweat If jogging, swimming or biking is part of your regular routine, there’s no need to skip Avoid endurance training, lifting weights and playing team sports Health.com — If you’re feeling under the weather, exercise may be the last thing you feel like doing – and it’s true that when your body’s already under a lot of stress, making it do more work isn’t always a good idea.

But in some cases, light to moderate activity may actually help you feel better, says Dr. Richard Besser, author of “Tell Me the Truth, Doctor: Easy-to-Understand Answers to Your Most Confusing and Critical Health Questions.” First, Besser says, use the “neck rule”: If your symptoms are above the neck – sneezing, sinus pressure, stuffy nose – then breaking a sweat is generally considered safe.

Listen to your body, and consider the following best (and worst) workout options. Having a cold may compromise your energy levels, so you may not feel up for intense physical fitness. But even just a 20-minute walk can help you reap the benefits of regular exercise, and it may help improve your cold symptoms, as well.

If your sinuses are plugged up, walking will stimulate you to take deep breaths and can help open up those passages,” says Besser. (Of course, if you discover that walking – or any type of physical exertion – makes you feel worse, rather than better, stop and focus on getting rest, instead.) Although there’s little research on how exercise can affect the duration of a cold, studies have shown that people who regularly work out tend to get sick less, overall.

As long as jogging is part of your regular routine, there’s no reason you need to skip it just because of a mild head cold. “My patients who are runners all say that running helps them feel better when they’re sick,” says Dr. Andrea Hulse, a family practitioner (and runner) in Silver Spring, Maryland.

Running is a natural decongestant, and it can help clear your head and feel normal again.” You can scale back the intensity of your normal run, Hulse says, since your body is already working in overdrive to help fight off infection. And the American College on Exercise recommends holding off completely if you’re experiencing flu-like or below-the-neck symptoms, like nausea or vomiting.

This type of slow, mindful movement is a cross between martial arts and meditation. It’s low-intensity enough for days that you don’t feel like breaking a serious sweat, and it has been used for thousands of years to reduce stress and anxiety, improve blood flow, and increase energy.

(In Chinese medicine, this is known as regulating and healing the body’s “chi,” or energy force.) There is some modern evidence that qi gong has immunity-boosting powers, as well: A 2011 University of Virginia study found that varsity swimmers who did qi gong at least once a week came down with 70% fewer respiratory infections that their teammates who practiced it less often.

Health.com: 7 strategies to love the way you look Training for a marathon? Skip this weekend’s long run if you’re sick – even if you’re already getting over, or just feel yourself coming down with, a cold. “In general, regular exercise stimulates the immune system and helps keep us healthy,” says Hulse.

• But too much regular exercise at a high intensity can have the opposite effect,” she adds.
• While no studies have looked at the effects of endurance running while already sick, Hulse says, its overall strain on the immune system is well documented: A 2007 study published in the Journal of Applied Sciences, for example, reported that immune function may be compromised for up to 24 hours after prolonged, continuous exercise (1.5 hours or longer).

The body releases the stress hormone cortisol while it’s fighting infections like the common cold, and research suggests that stress-relieving techniques – such as yoga and breathing exercises – may help boost immunity. Plus, says Besser, gentle stretching may help relieve aches and pains related to colds and sinus infections.

• Choose a slower style of practice, like Hatha or Iyengar yoga, if you’re worried about overdoing it with vigorous sun salutations.
• Or focus on restorative postures, like Child’s Pose and Legs Up the Wall, at home.
• And don’t forget to say “om”: A Swedish study found that humming is a good way to open up clogged sinus passages.

In addition to how you exercise when you’re sick, it’s also important to consider where you exercise: “If your workout involves going to the gym and being in close contact with other people, you need to ask yourself if you’d want someone else with your symptoms doing the same thing,” says Besser.

If you would not like the person next to you on the treadmill or who finishes before you on the elliptical to be sneezing and coughing and wiping their nose, than do your fellow gym mates a favor and do a lighter workout at home, instead.” Germs can spread easily on machines and in the locker room, he adds, so it’s best to stay away while you’re contagious.

Taking a Zumba or cardio dance class – or even just rocking out to your favorite tunes while you clean the house – can serve as a stress-reduction technique. In fact, one study found that people who just listened to 50 minutes of dance music had less cortisol and more cold-fighting antibodies – a sure boost to their immune systems.

• Dance classes tend to be low impact, so you can break a sweat without putting too much stress on your joints (or aggravating a cold-related sinus headache).
• You can go at your own pace, as well: Take it easy on days you’re not feeling 100%, and try to just enjoy the party.
• Your strength and performance will likely be diminished while you’re battling a cold, says Besser – especially if you’ve missed out on quality sleep – putting you at increased risk for injury while trying to lift heavy equipment.

Plus, the muscle strain required to lift weights can cause sinus pressure and headaches to feel even worse, he adds. Still don’t want to skip a strength workout? Do it at home, where you won’t be spreading germs and sharing your sickness with other weight lifters, and give yourself a break by using lighter dumbbells than usual.

1. Increase your reps, not the weight, if you need more of a challenge, says Hulse.) Health.com: The one-minute full-body workout Like walking and jogging, other forms of moderate cardio can help clear congestion and boost energy levels, says Hulse – but they won’t work for everyone.
2. It’s really a matter of personal preference, what type of symptoms you have, and what your normal routine is like,” she explains.

Swimming, for example, can feel quite refreshing, and may help open up airways. (For people who suffer from allergies, it can also help by washing away pollen and dust.) But some people may find it difficult to breathe while congested, or may be irritated by chlorinated waters.

• Biking can also be a nice, moderate exercise, but may dry out nasal passages and increase symptoms like sore throat and runny nose.
• Just like using the treadmill or weight machines at the gym, playing sports that involve physical contact can encourage the spread of illness.
• If you’re a pro athlete, then your coaches and teammates may expect you to be out there no matter what,” says Besser.

“But in something like a friendly neighborhood basketball league, they’re going to thank you for sitting one out.” Cold and flu viruses spread through droplets, like tears and saliva – but also through hand-to-hand contact, he adds. “If you wipe your nose and then you pass the ball, you’ve just passed those germs on, as well.” A 2011 study from the Centers for Disease Control and Prevention found that the sports teams are at high risk for outbreaks of the stomach flu norovirus among members.

• Health.com: What health pros order at restaurants Working out in freezing temps may be detrimental to some people battling cold symptoms, but not for the reason you may think.
• Contrary to popular belief, cold weather in itself will not lower immunity or cause you to get sick – not even if you go outside without a coat or you sweat so much your hair gets wet.

What can happen, however, is that cold, dry air can restrict or irritate airways – triggering a runny nose, coughing, or asthma-like symptoms, says Hulse. If you find that you are sensitive to these conditions, winter activities like skiing, snowboarding, or snowshoeing might be even more difficult when you have a cold.

• Plus: What about allergies? Sometimes, what people think of as recurring cold symptoms – sneezing, headaches, nasal congestion – are actually allergies in disguise.
• If you find that you are seeing those symptoms come on at the same time each year, you might want to ask your doctor about getting tested,” says Besser.

Allergies to pollen and ragweed can make outdoor exercise difficult in the spring and fall, he adds, while allergies to dust, mold or harsh cleaners can be triggered by workouts at the gym or in other enclosed spaces. If you can pinpoint the cause of your symptoms, an antihistamine or other treatment can likely help you get back to your normal life – and your normal workout routine.

What’s the best thing to eat when sick?

Foods to eat when sick – “Avoid things that can cause more problems, like spicy or fried foods,” Dr. Khan said. “Soups and broths can be helpful, and softer foods will be easier to handle. You want to eat healthy things that are easily digestible and not irritating to your stomach.” Eating fruits and vegetables that are high in vitamin C is a smart move.

Citrus fruits like oranges Leafy greens Broccoli Brussels sprouts Cantaloupe Kiwi Peppers Potatoes Strawberries Tomatoes

If you’re feeling nauseous, following the BRAT diet – bananas, rice, apples and toast – may be your preference. The BRAT diet does not have as many nutrients as other food options, but it is easy on the stomach. If you are having trouble keeping food down, this might be the way to go. : Foods to eat when sick with flu

Why are colds so miserable?

Understanding the Basics of a Common Cold A runny nose, scratchy throat, and nonstop sneezing – you can’t miss the signs of a cold. But mystery shrouds a lot of other things about it. Why do you seem to get them so often while your best friend stays well? And more importantly, how can you stay healthy this year? Get the lowdown on the all-too-common common cold.

1. It’s an illness caused by a tiny, infectious thing called a virus.
2. More than 200 types lead to your misery, but the most common one is the rhinovirus, which is thought to be responsible for at least 50% of colds.
3. Other viruses that can cause colds include coronavirus, respiratory syncytial virus, influenza and parainfluenza.

Colds cause a lot of people to stay home. The CDC says 22 million school days are lost each year in the U.S. because of them. Some estimates say that Americans have 1 billion colds a year. For more detail, see, You can catch it from another person who is infected with the virus.

1. This can happen by direct physical contact with someone who has a cold, or by touching a surface contaminated with their germs – like a computer keyboard, doorknob or spoon – and then touching your nose or mouth.
2. You can also catch it from infected droplets in the air released by a sneeze or a cough.

A cold begins when a virus attaches to the lining of your nose or throat. Your immune system – the body’s defense against germs – sends out white to attack this invader. Unless you’ve had a run-in with that exact strain of the virus before, the initial attack can fail and your body sends in reinforcements.

Your nose and throat get inflamed and make a lot of mucus. With so much of your energy directed at fighting the cold virus, you’re left feeling tired and miserable. One myth that needs to get busted: Getting chilly or wet doesn’t cause you to get sick. But there are things that make you prone to come down with a cold.

For example, you’re more likely to catch one if you’re extremely tired, under emotional distress, or have with nose and throat symptoms. When a cold strikes, you may have symptoms like:

Scratchy or sore throat Sneezing Stuffy nose Watery eyes Mucus draining from your nose into your throat

More severe symptoms, such as or muscle aches, may be a sign that you have the rather than a cold. For more detail, see, Children have about 5-7 colds per year. A big part of the reason: They spend time at school or in centers where they’re in close contact with other kids most of the day.

• Also, kids aren’t as conscientious about sneezing into the crook of their arm or frequent hand washing — not to mention keeping their hands to themselves.They may not have built up immunity to as many varieties (or strains) of colds as an adult.
• For in-depth information, see,
• In the U.S., most colds happen during the fall and winter.

Beginning in late August or early September, the rate increases slowly for a few weeks and remains high until March or April, when it goes down. The reason may partly have to do with the opening of schools. Cold weather may also play a role because it leads you to spend more time indoors with less air circulation, where you’re in closer contact with people who are contagious.

Changes in humidity in different seasons may also affect how often people get sick. The most common cold viruses survive better outside the body. Also, cold weather may make the lining of your nose drier and more vulnerable to an infection by a virus. Most colds last about 7 to 10 days, but if your symptoms linger, you may need to call the doctor.

Sometimes, colds lead to an infection by bacteria in in your,, or ears. If that happens, your doctor may prescribe antibiotics, which work against bacteria but not against viruses. For more detail, see, Need more info about the common cold? See,

Can you catch a cold through eyes?

Five Surprising Facts about the Common Cold – All of us will have had one and many of us will have one will be nursing one right now – but did you know the common cold harbours five surprising facts? 1) You can catch a cold through your eyes. When an infected person coughs or sneezes, they release tiny droplets into the air.

1. If these droplets get on to your hands, you can pass them into your eyes by touching them.
2. The virus can travel to the nose and throat through a duct that links the eyes and nasal cavity, where it then starts the process of causing an infection.
3. The best way to avoid letting the virus get into your system is good hygiene.

Wash your hands regularly, especially after touching potentially infected areas.2) The germs that cause a common cold can live for up to two days outside of the body. Think of all of the places where viruses could be hanging out.doorknobs, computer keyboards, smartphones, tablets, draw handles, bottles and jars.

You may be living with someone who has recovered from a cold, but the virus may still be present in your home. Regular wiping down of surfaces might prevent you from being the next victim of a winter bug.3) Taking Vitamin C does not keep colds at bay. There are plenty of good reasons to eat vitamin C packed foods like oranges and broccoli.

However, there is currently little evidence to suggest that ingesting this vitamin reduces your chances of getting a cold. Of course, eating healthily, and that includes eating lots of fresh fruit and vegetables, does contribute to a strong immune system and that will help you to fight off a cold.4) There are around 200 types of virus that cause common colds.

• With this many common cold viruses out there, it’s highly unlikely that doctors and scientists will find a cure for the common cold any time soon.
• Even if a vaccine or remedy is developed, it’s unlikely to be used widely as the various strains of the virus would then evolve to resist treatments.5) Over the centuries and around the world, lizard soup, blood-letting, leeches, turnips, plum pickle and the familiar chicken soup have all been used to treat colds.

NHS Vale Royal Clinical Commissioning Group (CCG) is advising people to stick to over the counter medications readily available at the pharmacy. If you are struck down with a bug this winter, take the following advice and you should start to see your symptoms go away in 7-10 days:

Your first point of call should be your local pharmacist. Use the medicines they provide, such as painkillers, decongestants and cold medicines to self-treat at home. They will also be able to advise you which medications are suitable for children. Try not to spread the bug to your relatives and friends. Be especially careful about mixing with children and the elderly who can be badly affected by a cold. Stay at home and get plenty of rest. Drink plenty of fluids. Eat healthily – a low-fat, high-fibre diet is recommended, including plenty of fresh fruit and vegetables.
