What does the cold temperature in the weather forecast mean and what does it mean?

What is sensory temperature? What do different levels of somatosensory temperature mean?

Somatosensory temperature refers to the temperature of the air felt by the human body, which may differ from the actual ambient temperature. This is because other climate-related conditions affect the heat convection between the air and the human body, causing the perceived temperature to be different from the actual temperature, so it is also called the apparent temperature.

The body-sensing temperature is affected by wind, humidity, sunlight, and the color of clothes on the temperature measured by the blinds. If the body-sensing temperature is higher than the air temperature, it means that the above factors are all warming the human body. The effect is on the contrary, it is the cooling effect.

The temperature in the weather forecast only represents the degree of warmth and coldness of the air, and cannot fully express the human body's feeling of warmth and coldness of the environment. However, the temperature can be used as a parameter of the human body's feeling of warmth and coldness. This is also the relationship between air temperature and The difference in body temperature. Under the same temperature conditions, people will also have different feelings of cold and warmth due to differences in air humidity, wind speed, clothing color, sunlight and even mood.

Somatosensory temperature classification

The human body feels temperature differently in winter and summer, mainly due to the different habits of the human body in the usual environment and the difference in air humidity

Winter

Very cold, very uncomfortable <4℃ (red)

Cold, very uncomfortable 4~8℃ (yellow)

Cool, uncomfortable 8～13℃ (blue)

Cool, more comfortable 13～18℃

Comfortable, most acceptable 18～23℃

Warm, most acceptable 23～29℃

Warm, uncomfortable 29～35℃ (blue)

Summer

Very cold ( It will be cold to death), cannot tolerate 13~18℃

It will be cold (will make you sick), wear thick clothes or hide under the quilt, barely tolerate 18~20℃

It is a bit cold , add some clothes and the most acceptable temperature is 20~25℃

Cool block, the most comfortable 25-26℃

Hot, uncomfortable 27~30℃

Very hot , need air conditioning or fan 30~33℃

Overheated, need to shower 33~35℃

Too hot, need frequent showers 35~37℃

Extremely hot , it will kill people>37℃

However, these are not absolute
