What is the normal range of human body temperature?
The starting point (zero point) of temperature reading and the basic unit of temperature measurement are specified. The international unit is the thermodynamic temperature scale (K). Other temperature scales widely used in the world are Fahrenheit scale (F), centigrade scale scale (C) and international practical temperature scale.
Influence on human body: According to the research of physiologists, about 30℃ is the best environmental temperature for human body, and it is also the temperature closest to human skin.
33℃- Sweat glands start working at this temperature for 2-3 hours, and the human body is in an "air-conditioned state"-sweat glands begin to emit accumulated body temperature through slight sweating.
35℃- the heat dissipation function reacts immediately. At this time, the superficial vein dilates, the skin sweats, the heart beats faster, and the blood circulation accelerates. For some elderly and infirm people with poor heat dissipation, it is necessary to cooperate with local cooling or turn on indoor air conditioning to reduce human body temperature.
36℃- 1 alarm At this temperature, the human body "cools itself" by evaporating sweat to release heat. Sweat, sodium, vitamins and other minerals will be excreted every day, and the blood volume will also decrease. At this time, drinks containing salt, vitamins and minerals should be supplemented in time to prevent electrolyte disorder in the body, and other cooling measures should also be started.
