Why is the temperature we feel different from the actual temperature?

Somatosensory temperature refers to the temperature at which the human body feels the air, which may be different from the actual environment temperature. This is because other climate-related conditions affect the thermal convection between air and human body, which makes people feel different from the actual temperature, so it is also called apparent temperature. The actual temperature is measured by the weather station, and the temperature is announced every day. The actual temperature in each area is the same, and it will not vary from person to person. This is a relative standard and a scientific measure. However, friends often wonder why today's weather forecast predicts the same temperature as yesterday, but today it feels hotter than yesterday. So why is the temperature we feel different from the actual temperature?

The temperature is very high in summer, and the heat generated by human metabolism depends on sweating and heat dissipation to maintain the balance of body temperature. If the humidity in the air is high and the sweat evaporates less, it will feel extremely sultry. If a gust of wind blows at this time, it will accelerate the heat dissipation of the human body and make people feel cool. However, the temperature has not changed at this time, which is the temperature people feel.

People's perception of temperature is related to temperature, humidity and wind. Scientists installed facilities that can adjust the temperature, temperature and wind speed in two adjacent laboratories with the same building structure. They set the temperature in the two laboratories to be the same, but the wind speed and humidity are different. Let the subjects walk into two laboratories and talk about their feelings. People who have been to the two laboratories replied in unison: the temperature is different, but when the temperature of the two laboratories is adjusted to be different, however, after adjusting the wind speed and humidity, people say that the temperature of the two laboratories is the same after leaving the laboratory. From this point of view, people feel different in the environment with the same experimental temperature because they think that the temperature is not only affected by the actual atmospheric temperature, but also by the atmospheric humidity and wind speed.

So it depends on how friends go out to dress.
