What is the Common Cold?
Whether it starts with a headache, a runny nose, or a fever, the common cold is an illness that most everyone has to deal with at one point or another – which is precisely why it’s called common! In just America alone, there are approximately one billion colds each and every year. Most of these colds happen during “cold season.” Cold season spans from September to April because of the cooler weather during this time and because children are in school and in such close contact with countless different germs.
Colds tend to last seven to 10 days, and because they are caused by viruses, there isn’t any medication that can make them go away faster. The best thing to do when you have a cold is to rest, drink plenty of fluids, and to treat your symptoms with over-the-counter medications. However, colds can linger and/or turn into something more serious such as the flu or a bacterial infection. In these cases, it’s always best to get checked out by a doctor.
Possible Symptoms for a Cold
1. Nasal Congestion
Nasal congestion is usually the most noticeable sign of the common cold. It’s often the reason people confuse the common cold with the flu or with allergies, because all these issues cause the nose to become extremely stuffy. When your body comes into contact with the virus, your nose is strongly affected and begins to get stuffy. Congestion can be uncomfortable and make it difficult to complete your day-to-day tasks.
2. Runny Nose
When your nose becomes stuffy, it may also start to run, especially with a cold. You’ll need to constantly wipe or blow your nose. A runny nose is often one of the best ways to tell if you or someone else has a cold.
Nasal congestion and a runny nose lead to sneezing. These are the most common symptoms of a cold, because the condition is caused by a virus that generally begins in the nose and throat. You may sneeze constantly, more frequently, or more violently than normal.
4. Scratchy Throat
When you have a cold, a scratchy throat or throat pain occurs because the mucus in your nose leaks down into your throat, causing you to swallow it. This leads to an uncomfortable and sore throat, and it can be hard to swallow or talk. You might wake up with a scratchy throat as the first sign of your cold.
Not every virus that causes the common cold comes with coughing, but many do. It can be very uncomfortable to have a persistent cough when you’re dealing with a cold, which can cause or exacerbate a scratchy throat.
Top 3 Causes of a Cold
There are many types of viruses that cause the common cold, and a number of ways a person contracts a cold virus.
1. Breathing in the Virus
When you breathe in the same air as a person who has a cold, usually in a confined space like a classroom or office, you will likely contract the virus. Traveling by bus, train, or plane can also expose you to a virus in a space with air that is recycled. If someone sneezes or coughs on or near you while they are contagious, you may contract a cold. Individuals are usually the most contagious for the first few days of having a cold.
2. Touching a Person With a Cold or an Item That Has Been Infected
When you touch someone who has a cold and then touch your eyes, mouth, or nose, this can quickly cause you to contract a cold yourself. Cold viruses can also be transmitted through objects. When you touch something that belongs to someone else, such as keys, the item may have the virus on them. Even if you touch something that has been touched by a sick person briefly, like a doorknob, you could still become infected, up to several hours later.
3. Lowered Immune System
If you have a compromised immune system, as many children and elderly people do, you are more susceptible to contracting a cold. If you are tired, stressed, smoke, or have a poor diet, you are more vulnerable to catching a cold as well.
3 Ways to Prevent a Cold
1. Washing Your Hands
Washing your hands often is one of the best ways to protect yourself against the common cold. Be sure to wash your hands after interactions with others or after being somewhere that likely has a lot of germs, such as a public restroom.
2. Don’t Touch
When you are out and about, try not to touch your face, nose, mouth, and eyes. Try to avoid touching objects that many people handle, such as doorknobs, staircase or elevator railings, and household items like remotes. This is a good rule of thumb if you’re around kids or people you know are experiencing a cold.
3. Avoid Being Around People With a Cold
One of the best things to do to protect yourself is to avoid being around people with a cold. Try not to come into close contact with them if you can’t avoid them entirely. If you have a cold make sure to cover your mouth when you sneeze or cough and, if you can, stay home while you are sick or while you are most contagious.
Possible Cold Treatment Options
Unfortunately, there is no one cure or treatment for the common cold, but there are a few things you can do to help yourself feel better.
Make sure to get plenty of rest. Even if you can’t sleep, you may want to lie in bed and read or watch TV. Do low-impact activities for a while to avoid feeling worse or prolonging your cold.
2. Drink Fluids
Drink lots of fluids to avoid getting dehydrated during your cold. Drinking water and other healthy fluids also helps flush the sickness out of your system more quickly.
3. Take Medicine
Although medicines can’t cure your cold, they can help you feel better faster. Over-the-counter medicines like painkillers, cough drops, throat sprays, and cold medicines, can relieve symptoms and help you sleep better so that you can get healthier more quickly.
