Physics, Chemistry, Biology – Why keep it cold? – SRF mySchool



content

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

The common cause of colds is a small virus that enters our body through the respiratory tract. They proliferate in the nose, throat and bronchi of our lungs. Who sneezes, throws their virus into the air in a few feet of air and this way it infects other people. Even if we shake the hand of the other side, it may spread cold.

However, we are not at the mercy of the common cold. Our immune system, which is an internal defense system, is an obstacle to viruses unless it is too much at once. If he does, he gets sick and has the typical symptoms: chills, sore throat and runny nose. If you have severe chills, high fever, body aches and cough, you may have flu. This can last up to 14 days and can sometimes be dangerous.

When colds are caught, it helps to relax, so the immune system can protect the virus well. Drinking enough tea or water helps the immune system. Lozenges also relieves cough and sore throat.
