How do changes in weather affect human health? Why are temperate zones most suitable for human survival?
Among the regulatory mechanisms of our entire human body, the temperature regulation center is controlled by the hypothalamus and pituitary gland. So in fact, the surface temperature that our entire human body endures is about 37°C, that is, in the body, our normal temperature is about 36 to 37°C. If our body temperature changes too high or too low If so, it will affect our human health, and the temperature of our body surface may change with the outside atmospheric temperature, so changes in the weather are actually directly related to our human health, just like We often say that in fact, the environment in which we live is most suitable for our survival is the temperate environment.
For example, if the weather changes, when the external environment temperature is relatively high, then we may collectively be unable to withstand such a high temperature and the sudden exposure to sunlight, which may stimulate our The cerebral cortex feeds back to our temperature regulation center, causing a compensatory or negative feedback regulation mechanism. When the negative feedback adjustment mechanism cannot compensate, it will cause some bad physical manifestations, just like when the weather is hot in the summer, if we exceed the body's tolerance, then there will be A heat stroke may occur.
In winter, the weather changes greatly, and the external environment is relatively cold. We usually wear some warm clothes to keep the body warm. When the temperature changes, the weather becomes colder or When it rains outside and the surrounding environment is relatively humid, some of our patients with bone and joint diseases may develop gout and rheumatoid arthritis. When the external environment is relatively humid, it may cause When gout attacks cause pain in some small joints, it is also directly related to our human health.
When the weather is hot or cold, the blood vessels will shrink and corresponding changes will occur in the books, which has a direct impact on the perfusion in our bodies. Therefore, for the adaptability of our body, the best thing is to have a suitable temperature. We all know that suitable temperature is the best. If something is too high or too low, it will affect it.
