How does the change of weather affect human health? Why is temperate zone the most suitable for human survival?

In the regulation mechanism of our whole human body, the thermoregulation center is dominated by hypothalamus and pituitary gland. So in fact, the surface temperature of our whole human body is about 37℃, that is to say, in the body, our normal temperature is about 36℃ to 37℃. If our body temperature changes too high or too low, it will affect our human health, and our body surface temperature may change with the change of external atmospheric temperature, so the change of meteorology is actually directly related to our human health, as we often say.

For example, when the temperature of the external environment is relatively high, it may be that we can't bear such high temperature and intense sunlight, which may stimulate our cerebral cortex to feed back to our body temperature regulation center, thus producing a compensatory or negative feedback regulation mechanism. When the adjustment mechanism of negative feedback is not compensated, it will lead to some bad performance of the body, just like when the weather is hot in summer, so if we exceed one of the body's endurance, then there may be a state of heatstroke.

In winter, the weather changes greatly and the external environment is cold, so we usually wear some warm clothes to keep our bodies warm. Then, when the temperature changes, the weather is cold or it rains outside, and the surrounding environment is humid, then some of our osteoarthropathy patients may have gout and rheumatoid arthritis, for example. When the external environment is humid, it will lead to gout attack and cause some small joint pain.

When the weather is hot or cold, the contraction of blood vessels and the corresponding book changes will have a direct impact on the perfusion in our body. Therefore, for an adaptive existence of our body, it is best to be at a suitable temperature, and we all know that the right is the best. Too high and too low will affect it.
