Somatosensory temperature weather forecast

Ice cream assassin? Let netizens can't afford cheap ice cream, and the continuous high temperature in various places also leads to it? Heatstroke? Often, the summer of 2022 is destined to be an extraordinary summer. Although it is already three or four o'clock in the afternoon, the sun is still very sunny. On the street, there are friends who wear sun protection clothes and goggles to wrap themselves up. Many people even feel that the temperature they feel is higher than that reported in the weather forecast. Is it because they are hallucinating? In fact, from a scientific point of view, there are some differences between the somatosensory temperature and the actual temperature. The somatosensory temperature is mainly influenced by air humidity, wind speed and people's mood changes, so many people feel that the somatosensory temperature is much higher than the actual temperature in hot summer.

In the weather forecast, the temperature we see only represents the change of local temperature, and can't fully show the human body's perception of environmental changes. Therefore, temperature is usually only regarded as a parameter, that is, the difference between the somatosensory temperature and the actual air temperature. Because in the same environment and temperature, the human body will have different feelings because of the size of wind speed, different clothes, air humidity and changes in mood at that time. For example, in an environment of 30 degrees, if the relative humidity of the air is kept between 40% and 50% and the wind speed is kept above three meters per second, then the human body will not feel the heat of the weather. However, at the same temperature, if the relative humidity is as high as 80% and the wind speed is relatively small, there will be sultry feeling, and even coma and heatstroke will occur for some weak patients.

In addition, it is also affected by humidity. At the same temperature, the greater the relative humidity, the higher the somatosensory temperature will be. For example, in an environment of 30 degrees, if the local humidity is 50%, the somatosensory temperature is 1. 1 degree higher than the actual temperature, reaching 3 1. 1 degree. At that time, the relative humidity rose to 90% and the somatosensory temperature soared to 40.6 degrees, which was 10.6 degrees higher than the actual temperature. It can be found that if the relative humidity in the air is high in summer, the difference between the two temperatures will be more obvious.

Finally, I feel that the outside temperature is higher than the actual temperature, which is also affected by the heat dissipation function of the human body, because the human body will gradually weaken or even lose with the increase of the outside temperature and humidity. According to relevant research, if the actual temperature reaches 4 1 degree, it may threaten life and health, because the organs that can cool down, such as breathing, perspiration and blood circulation, are in a weak state, and it is difficult to cool down the body by using the heat dissipation function of the human body. Therefore, in the hot summer, we must take some measures to reduce the somatosensory temperature and avoid irreversible harm to the body.
