Physics, Chemistry, Biology – Why do we catch a cold? – SRF mySchool



content

Winter time is cold weather. On average, two to four times a year, adults have small, cold children up to ten times a year. Cold is one of the most common diseases in Switzerland. Reena explains why we caught a cold and what we can do about it.

The cause of a cold is a small virus that enters our body through the respiratory tract. They multiply in the nose, throat and bronchi of our lungs. Whoever sneezes, flings their virus several yards through the air and infects other people in this way. Even if we shake the hand of our counterpart, a cold can spread.

However, we are not at the mercy of a cold. Our immune system, an endogenous defense system, forms a barrier against viruses as long as there are not many at the same time. If this happens, we get sick and have the typical symptoms: tremors, sore throat and runny nose. If we also have severe chills, high fever, body aches and coughing, it may be the flu. This can take up to 14 days and sometimes even dangerous.

When you catch a cold, it helps to rest, so the immune system can defend the virus well. Drinking enough tea or water helps the immune system. Lozenges also relieve cough and sore throat
