Cold is not related to hypothermia
There is an opinion that as soon as a person freezes, a cough with a runny nose begins. In fact, the viruses in the air around us are to blame. If you inhale enough of them, and your immune system is not ready to defend itself — you will get sick.
And here the humidity of the environment plays a significant role, not the temperature. The more moisture in the air — the easier it is for viruses to be transmitted from person to person with droplets of water.
To be fair, it should be mentioned that hypothermia reduces the degree of immune protection. This happens due to the narrowing of small capillaries in the mucous membranes of the nose and mouth from the cold. Blood circulates worse in these areas and immune defense cells cannot fully «parachute» at the site of virus penetration. However, this is an auxiliary mechanism, not the main one.
How to protect yourself?
Firstly, keep your immune system ready for battle! Regular physical activity, a balanced diet, and a healthy 8-hour sleep will help you with this.
Secondly, try to avoid large gatherings of people. For example, in public transport, a closed space is created, and if someone coughs — the amount of pathogen in the bus increases. It is better to stay away from people with a cold. The radius of particularly high danger is one and a half meters.
Thirdly, get a flu shot. Many people confuse a cold with the flu and do not understand that the flu poses a real danger to the cardiovascular and nervous systems. New flu vaccines are created every year. All you need to do to protect yourself from the most dangerous scenario is to see a doctor and get vaccinated. In 2019, the vaccination costs about 300 hryvnias, this amount is not so large compared to the costs of treating the flu. And what about the horror stories about vaccinations? We tried and collected reliable information about vaccination here.
