Why do people die in hot weather?

The weather is hot, people are easy to dehydrate, so we should replenish water and salt in time. High temperature weather can also induce many diseases, such as cardiovascular diseases. Especially the elderly, and some jobs at high temperature are also prone to heatstroke or sudden death.

Britain and Japan are both countries with maritime climate, and the average temperature in summer is lower than that in inland areas such as Chongqing and Sichuan, so the sudden high temperature will make local people uncomfortable, and it is easy to be dangerous without preventive measures.
