What is a temperature that is too cold for humans?

A temperature that is considered too cold for humans typically falls below freezing, around 32°F (0°C). Prolonged exposure to temperatures below this can lead to hypothermia and frostbite, especially if accompanied by wind and moisture. Generally, temperatures lower than 50°F (10°C) can be uncomfortable for many people without proper clothing and protection. However, individual tolerance varies based on factors like age, health, and acclimatization.
