Why does the human body sweat? Is sweat homologous to blood?

Sweating is one of the so-called night sweats.

Night sweats is a syndrome name of traditional Chinese medicine, which is characterized by abnormal sweating after falling asleep and stopping sweating after waking up. "Stealing" means stealing. Ancient doctors described this disease as thieves sneaking around every night. Whenever people fall asleep, or just close their eyes and fall asleep, sweat leaks out like a thief. Night sweats can be divided into physiological and pathological. Umbilical therapy of traditional Chinese medicine is very effective in treating night sweats. Patients with night sweats should pay attention to self-care, strengthen physical exercise and reasonable diet conditioning.

As for sweat and blood, sweat and blood are not directly related, but they are indirectly related. The faster blood circulation, the more sweating; On the contrary, there will be less or even none. The main component of sweat is water, and the main component of blood is also water. When the blood circulation is accelerated (first, because of exercise, and second, because the body temperature rises due to nervousness and excitement, so it is necessary to accelerate the circulation and heat dissipation), the total volume increases, and water will be discharged from sweat glands to achieve the purpose of balanced heat dissipation.
