Why do you get sick in December?

Cold weather and lack of sunlight are two reasons why people easily fall ill in the last month of the year.

It's no coincidence that every time the cold season comes, we start coughing and sneezing. Here are 3 reasons why winter makes you susceptible to illness, according to Medical Daily.

Cold weather

You may be annoyed by your parents' constant reminders to wear more clothes in the winter. However, in fact, this advice is extremely useful because researchers have shown that the viruses that cause colds in humans love warm environments like the nose and intestines.

Cold air also weakens the body's ability to defend itself, the immune system produces less antiviral substances so pathogens quickly develop.

It's dark.

In winter, especially in the North, the sun rises after you've left for work and sets before you get home. That means you don't get as much sun exposure and your skin produces less vitamin D.

Not only does vitamin D prevent respiratory infections, it also supports immune function, bone growth and calcium absorption, and mental health.

Germs are everywhere

The more people around you are sick, the more likely you are to catch the virus. Don't forget that most of us wash our hands less in the winter, creating conditions for pathogens to spread. The US Centers for Disease Control and Prevention (CDC) warns that germs spread into the environment through sneezes and coughs can survive for 2 hours on surfaces such as doorknobs, tables, and refrigerators. That means if person A coughs on his hand and touches the coffee pot, then person B picks up the pot and then puts his hand to his face, he is very likely to get sick.

Additionally, the CDC notes that many people with the flu do not realize they are sick and do not have time to limit contact with the surrounding community. They can infect people within 2 meters of them./.
