The human body is also 37 degrees. Why do people feel hot when the temperature reaches 36 degrees?

The human body is constantly undergoing metabolism. As long as there is metabolism, heat will be generated. Metabolism is a process that continuously releases heat. Because the human body needs to maintain a normal body temperature. , so heat will continue to be released.

The human body temperature is 37 degrees. This is the temperature inside the human body. When the human body temperature reaches 37 degrees, it begins to emit heat to the outside world. Therefore, when the temperature reaches 36 degrees, people will feel hot. , and when the temperature reaches 37 degrees, the human body begins to release heat. These two meanings are different.

The rectal temperature that can be directly measured by the human body and is closest to the internal body temperature is the rectal temperature. But at any time the body surface temperature is lower than the body temperature. When the outside temperature is higher than 36 degrees, it is actually higher than the temperature of the skin surface. At this time, the human body will dissipate heat outwards, so the body will feel hot, and you can still feel the heat. This is also because the skin cannot dissipate heat. It just happened. The cold and heat that the human body can feel are not directly related to the changes in the external environmental temperature. It is not absolute. It is mainly related to the speed of heat dissipation of the own skin, but the degree is related.

In cold conditions, you can maintain your body temperature unchanged, and it will not even gradually drop due to a drop in the temperature of the outside environment. When you exercise heavily, a particularly large amount of heat will be generated. At this time, the heat must be dissipated as quickly as possible. When the external ambient temperature is higher than the human body's temperature, or when the humidity is relatively high, the human body's heat dissipation will be blocked, and at this time the person will feel the heat. , but if a person is in the water, because the specific heat capacity of the water is relatively large, who can quickly take away a lot of heat at this time, so the person does not feel hot even if the temperature is more than 30 degrees in the water, and if If it is in an air environment, the way a person can feel hot or cold is related to how quickly the human body dissipates heat.
