Why is it that my body is cold even though it is very hot?
The human body has a self-regulating system that automatically maintains a normal body temperature. Because in summer, the air temperature is higher than the human body temperature, so the body takes away heat from the body through a large amount of perspiration, thereby maintaining a normal body temperature. Because of the temperature difference between the air and the body, it may feel like the body is cold, but in fact, if you use a thermometer to measure it, it will be the same as the body temperature in winter.
This is the same as the water in the well is cold in summer and hot in winter. In fact, the temperature of the water in the well is always the same. It’s just that in winter the air temperature is very low, lower than the water temperature, so the water feels hot. On the contrary, in summer, the air temperature is very high and higher than the water temperature, so it feels cold.
During vigorous physical exercise, the body consumes a large amount of energy and releases a large amount of heat. The body temperature rises, accompanied by accelerated heartbeat, blood circulation, and breathing. In order to maintain the physiological homeostasis of the human body, the body releases heat through perspiration and lowers the body temperature. Since the body's direct energy source ATP and the indirect creatine phosphate have been basically consumed, it is difficult for the body to continue to release heat through this energy source to maintain the body temperature. The body will feel cold and the immunity will be reduced. It is easy to cold.
With the improvement of living standards, there are fewer people with qi and yang deficiency. However, due to the accelerated pace of life, people's mental pressure has increased, and nightlife has become increasingly rich, there have been more people with yin deficiency.
People are divided into yin and yang, yang refers to the body’s functions, and yin refers to the body fluids in the body, including blood, saliva, tears, semen, endocrine and oil secretion, etc. "People with yin deficiency will show insufficient yin and fluid. The body of people with yin deficiency will be in a state of dehydration, resulting in dry eyes, dry nose, dry mouth, rough skin, and dry hair."
The causes of yin deficiency The reasons include congenital genetic factors, but improper living habits can also cause Yin deficiency. Young and middle-aged people are faced with great pressure from work and family, and their physical strength and energy are obviously exhausted, which is very likely to cause autonomic nervous system disorders in the human body. If they do not pay attention to replenishing "qi" in daily life, they will inevitably be "favored" by yin deficiency, resulting in night sweats, Dry skin, insomnia and dreaminess, etc.
