Why do northerners attach great importance to keeping their feet warm in winter, while some people in the south can wear slippers barefoot?

The human body is very sensitive to temperature changes, and its ability to withstand low temperature conditions is relatively limited. Under the condition of low temperature, it won't be long before the body feels unwell, and if it is serious, it will get sick.

Therefore, keeping warm in winter is a very important issue for each of us.

On the issue of keeping warm, there is a very interesting phenomenon: northerners pay special attention to keeping their feet warm and wear cotton shoes in winter, while some people in the south can wear slippers barefoot for winter ... because of the climate and environmental temperature.

Winter in the north is very cold, and because the humidity is relatively low, it is the feeling of "dry and cold". ..... Such environmental conditions for northerners, we must pay attention to keep warm, especially the feet. ..... This is because the warmth of feet directly affects a person's somatosensory temperature and his own health. ..... warm feet, warm all over. ..... If you are cold under your feet, you will be cold all over. ..... Because of this, northerners pay special attention to keeping their feet warm.

As for the problem that southerners wear slippers in winter, it is actually because the local ambient temperature is relatively high. ..... Because the climate is warmer, there is no need to deliberately keep warm. Even if you wear slippers, you can still spend the winter. ..... and once the local weather is cold, those who wear slippers will immediately put on cotton shoes.

Therefore, for this problem, we can understand it like this:

1, keeping feet warm is very important for human body.

Both northerners and southerners should pay attention to keep warm.

3. The specific warm-keeping measures depend on the local temperature.
