Hypothermia, a condition in which the body’s core temperature drops below 95 degrees, is the No. 1 killer of outdoor recreationists. Most cases occur in air temperatures of 30 to 50 degrees. But people can succumb to overexposure even at 60 or 70 degrees.

Once the temperature is below 68°F, death is almost certain. Even a warming up too fast could be dangerous: in cold water blood vessels in the skin and in the extremities dilate and blood pressure decreases rapidly, so there is a threat of a circulatory collapse.

43 °C (109.4 °F) – Normally death, or there may be serious brain damage, continuous convulsions and shock. Cardio-respiratory collapse will likely occur, 90% of people dies at this hot.

At a core temperature of 91 F (33 C), a person can experience amnesia; at 82 F (28 C) they can lose consciousness, and below 70 F (21 C), a person is said to have profound hypothermia, and death can occur, Sawka said. In other words, death strikes long before the body actually freezes.

High environmental temperatures can be dangerous to your body. In the range of 90˚ and 105˚F (32˚ and 40˚C), you can experience heat cramps and exhaustion. Between 105˚ and 130˚F (40˚ and 54˚C), heat exhaustion is more likely. You should limit your activities at this range.

If it is too cold outside to begin with, they will call recess off. Most schools that experience cold or extreme cold climates will cancel recess when the temperature is at 32 degrees. The 32-degree marker is the freezing point. This is when most people can start to develop frostbite.

Depending on the season, the ideal house temperature for both comfort and efficiency is between 68 to 78 degrees Fahrenheit. In the summer, the recommended thermostat setting is 78 degrees F. In the winter, 68 degrees is recommended for energy savings.
