Body heat does not know the disease.
White blood cells can kill bacteria and viruses that invade the body, and can defend against foreign enemies and protect the body. The action of white blood cells becomes exuberant when the body temperature rises. When we were in college, we did this test - blood was taken from the subject every hour to observe changes in the activity of white blood cells. It was found that after bathing and exercising, the subject's body temperature increased, and the activity of white blood cells became vigorous.
Cancer is now the number one cause of death worldwide. As an "incurable disease", cancer is feared by the world. However, we found that cancer cells in the human body had a body temperature of 393 and above. In other words, if a cancer patient has a high fever due to malaria or pneumonia, the cancer cells in his body will die naturally.
It can be seen that body heat plays a very important role in maintaining health and fighting off diseases. On the contrary, if the body is cold, it will not be able to defeat the disease, let alone maintain health.
Body cold" makes immunity low.
White blood cells are responsible for defending the body from external enemies, and they are active in high body temperatures, but their function is inhibited in low body temperatures. When body temperature drops1, immunity decreases by about 30%, and basal metabolism (the minimum amount of energy required by the body to sustain life in a awake, quiet state) decreases by about 12%.
In contrast to white blood cells, which are "refreshed" when exposed to heat, cancer cells die when the body temperature is high, but once the body temperature drops, the vitality suddenly increases. We have learned through experiments that cancer cells multiply very vigorously at 35 degrees Celsius.
