What month is sauna day in Beijing?

According to NOAA standards, at the same temperature, the greater the relative humidity, the more obvious the increase of somatosensory temperature. When the maximum temperature is ≥32℃ and the daily average relative humidity is ≥80%, the somatosensory temperature will exceed 45℃, which is called sauna day.

According to reports, if the temperature is high, but the humidity is low, it is at most "baked". If the humidity is high, it is "steamed" in the case of hot and humid.

From the data analysis, the number of sauna days is positively correlated with the number of days with humidity higher than 80%. When the overall temperature is high in summer, whether to steam sauna depends mainly on humidity.

When the temperature reaches a high temperature of 35.6℃, the humidity only needs 75% to exceed 55℃. It can be said that sultry sauna is more difficult than dry and hot baking.

Extended data:

According to the data of 198 1-20 15, the top ten provincial cities with the most sauna days per year are concentrated in the southern region. According to the statistics of the past 35 years, the longest continuous sauna days appeared in Haikou, and both 1989 and 1998 lasted for 14 days. Guangzhou also encountered a 10-day sauna day.

Among the northern cities, there are relatively many sauna days in Zhengzhou, with an average of more than 6 days per year. Secondly, Shijiazhuang, Tianjin, Jinan and Beijing will also have sauna days of 1 day or more.

In a year, sauna days are most likely to appear from June to August, and the most serious period of sauna days is 10- 16. Studies have shown that when the temperature, sunshine and relative humidity exceed certain conditions, people's emotions are also prone to "heatstroke", leading to depression, irritability and eccentric behavior.

Experts remind that sauna days should keep the environment naturally ventilated, and at the same time replenish water in time to avoid the time around noon. We should also keep enough sleep, and always have summer-heat drugs such as Huoxiang Zhengqi Water and Fengyoujing.
