The influence of too hot weather on human body

As we all know, human body temperature is constant, so why do you feel comfortable in sunny spring or autumn, but not in hot summer? This is because different temperatures have different effects on human physiological activities, and high temperature is not conducive to the regulation of human body temperature. Under normal circumstances, the human body regulates body temperature through conduction, convection, radiation and water evaporation, making it suitable for the inside and outside. The hot weather makes it difficult for the human body to dissipate heat, and the body temperature regulation function is limited, which is easy to cause heat accumulation in the human body and cause heatstroke. It can be seen that high temperature is a disastrous weather, especially continuous high temperature, which is very harmful to human body.

1. High temperature directly leads to diseases.

Under the condition of high temperature, diseases directly caused by high temperature include heatstroke and mental and neurological disorders.

Heatstroke is an acute heatstroke disease caused by the disorder of central nervous system and cardiovascular system due to heat balance and water and salt metabolism in high temperature environment.

Mental illness, also known as thermal fatigue, refers to the adverse effects of high temperature environment on mood, work ability and technical efficiency.

2. Diseases induced by high temperature

In the high temperature environment, because the human body is in a state of thermal stress, sympathetic nerves are excited, sweating a lot, blood viscosity increases, the cardiovascular system is in a state of high load operation, and the function of digestive system is weakened, which leads to the aggravation of the original diseases, such as sudden changes in blood pressure in the early and late heating, which can induce heart disease, congestion, coronary heart disease and so on.

Increased blood viscosity can lead to thrombosis and stroke; The weakness of digestive system leads to the poor nutritional status of human body, which further aggravates the original organic diseases.
