It’s no secret that cold weather increases illnesses and makes us feel weak, and it’s no coincidence. These types of temperatures can increase diseases for a few specific reasons, which I will show below.

When the cold season begins, we like to close all the windows or spend the whole day in a closed room. It can be very negative when talking about diseases. A 2011 study, It found that students became sick more regularly when they spent days locked in their dormitories, suggesting that a dry, ventilated climate was more conducive to disease. Germs from sneeze droplets last longer in dry weather. That’s why it’s best to open all windows regardless of the outside temperature when you catch a cold.

You are exposed to germs

As we spend more time indoors, our exposure to germs increases, and they love to live on doorknobs, computer keyboards, electronic devices, and other everyday objects. When you spend a lot of time in these rooms, germs spread quickly because you are constantly in contact with these germs. For this reason, it is recommended to disinfect everything or wash your hands frequently whenever you have the chance.

Decreased immunity

It is no coincidence that colds are associated with diseases, because in these climates the immune system is affected and slows down. A 2014 study conducted at the University of Yale It has been discovered that the immune response is usually very slow. The response of this system exposed to different temperatures is examined, as the cells lining the nose are found to be more deficient in this type of climate. This research was conducted in laboratory rats, and although a little more information is needed, these responses are believed to have strong similarities to the human system.

Fever spreads very quickly

No one should be surprised to get a fever every time the temperature drops. This is because the flu virus spreads much faster in cold weather. As indicated National Institutes of HealthThis may be a consequence of the fact that the lipid layer of this virus becomes more resistant and hardened at this temperature, meaning that it is more resistant and active, increasing the possibility of its spread.

How to avoid getting sick?

Now that you know what causes illness during these times, here are some recommended preventative measures. Northwest Medicine

• Wear a mask. Masks can prevent respiratory droplets from reaching other people, a way for germs to spread. You should wear a mask even if you don’t feel sick.
• Wash your hands. Germs on your hands can infect you or others. Washing your hands regularly will help protect you from diseases.
• Do not touch your face. Avoid touching your eyes, nose and mouth with unwashed hands.
• See your doctor and get vaccinated. Regular exams, screening tests, and vaccinations can help prevent illnesses and complications caused by common viruses.
