It's also hot weather. Why is damp heat more dangerous than dry heat?

Everyone hates hot weather, because it makes people listless and want to do nothing. Because human beings are warm-blooded animals, they can only live normally if their body temperature is maintained at around 36 degrees Celsius. When the body temperature is too high, everyone may suffer from heatstroke. It's also hot weather. Why is damp heat more dangerous than dry heat?

First, wet heat and dry heat may be that many people are not particularly clear about these two concepts. The following small series will introduce these two concepts in detail. When we usually say damp and hot, we actually mean that the relative humidity is relatively high. At this time, everyone will feel sultry and sweat will not be evaporated, so everyone may feel very uncomfortable. The so-called dry heat is actually a relatively low relative humidity, but at this time, everyone's sweat can evaporate, so everyone just feels that the weather is hot, but it will not feel particularly uncomfortable.

Second, why is damp heat more dangerous than dry heat? Although these two states make people feel uncomfortable, damp heat is more dangerous than dry heat. The most favorable humidity range is between 45% and 65%. If the humidity of the air is lower than 45%, the air will become dry and the human body will feel very uncomfortable. If the air humidity is higher than 65%, people are very prone to heatstroke at this time, so the human body can survive in a dry and hot environment, but there is no way to survive in a hot and humid environment, because the human body may suffer from heatstroke. The human body can't stand it for a long time in this environment, mainly because the sweat on the human body can't evaporate, so it will lead to a rapid rise in human body temperature.

Therefore, everyone must do a good job in heatstroke prevention in such an environment, so damp heat is actually more dangerous than dry heat, because people's body temperature will rise, so it is easy to cause heatstroke. And people may get heatstroke, and the survival probability of heatstroke is only 50%.
