Humans and winter Humans evolved in tropical climates, and met cold weather as they migrated into Eurasia, although earlier populations certainly encountered Southern Hemisphere winters in Southern Africa. Micro-evolution in Caucasian, Asiatic and Inuit people show some adaptation to the climate.

Winter and human health

Humans are sensitive to cold, see hypothermia. Snowblindness, norovirus, seasonal depression, slipping on black ice and falling icicles are other health concerns associated with cold and snowy weather. In the Northern Hemisphere, it is not unusual for homeless people to die from hypothermia in the winter.

One of the most common diseases associated with winter is influenza. Symptoms include: headache, fever, muscle pains, sinus infection, fatigue, dizziness, cough, and loss of appetite.
