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.
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.

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 ...
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 ]
Humidity affects thermoregulation by limiting sweat evaporation and thus heat loss. [6] Humans cannot survive prolonged exposure to a wet-bulb temperature above 35 °C (95 °F). Such a temperature used to be thought not to occur on Earth's surface but has been recorded in some parts of the Indus Valley and Persian Gulf.
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.
