But does cold, wet weather actually make you sick? Not really, experts say. Not really, experts say. But cooler temperatures and dry winter air can affect your body in surprising ways.
When people sick with a common cold or COVID-19 cough or sneeze, they let out respiratory droplets containing the virus, said Andrew Pekosz, a professor of molecular biology and immunology at ...
Humans adapted to heat early on. In Africa, the climate selected for traits that helped them stay cool. Also, humans had physiological mechanisms that reduced the rate of metabolism and that modified the sensitivity of sweat glands to provide an adequate amount for cooldown without the individual becoming dehydrated.

Hypothermia can happen in most mammals in cold weather and can be fatal. Baby mammals such as kittens are unable to regulate their body temperatures and have a risk of hypothermia if they are not kept warm by their mothers. Many animals other than humans often induce hypothermia during hibernation or torpor. [citation needed]
Cold shock response is a series of neurogenic cardio-respiratory responses caused by sudden immersion in cold water. In cold water immersions, such as by falling through thin ice, cold shock response is perhaps the most common cause of death. [ 1 ]
Colds are minor infections of the nose and throat and are caused by more than 200 different viruses, according to the American Lung Association.
A cold weather strategy is to temporarily decrease metabolic rate, decreasing the temperature difference between the animal and the air and thereby minimizing heat loss. Furthermore, having a lower metabolic rate is less energetically expensive. Many animals survive cold frosty nights through torpor, a short-term temporary drop in body ...
Wrapping up warm, eating well and exercising indoors will help keep your blood pressure levels stable this winter.
