This increases heat production as respiration is an exothermic reaction in muscle cells. Shivering is more effective than exercise at producing heat because the animal (includes humans) remains still. This means that less heat is lost to the environment through convection. There are two types of shivering: low-intensity and high-intensity.
Studies have shown that the warmth from the fires they build is enough to keep the body from fighting heat loss through shivering. [18] Inuit use well-insulated houses that are designed to transfer heat from an energy source to the living area, which means that the average indoor temperature for coastal Inuit is 10 to 20 °C (50 to 68 °F).

“The higher the humidity, the lower temperatures you need for extreme heat,” Linden said. High body temperatures can lead to damage to the brain and other vital organs, the CDC says. They can ...
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
At internal temperatures that high, the body’s vital organs can start to fail, not only because of the direct effect of the heat, but also because of the inflammation that the body produces in ...
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature.

Allen's rule - Hare and its ears on the Earth [1]. Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, [2] [3] broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates.
