How does fever shake headache to return a responsibility?
First: how does fever lead to headaches? Under normal circumstances, The hypothalamus has a center for heat production and heat dissipation, which can sense the information from the external environment and the temperature changes in the body, and maintain the body temperature at 37 ℃ by automatically regulating the relaxation and contraction of skin blood vessels, the secretion of sweat glands or the movement mode of skeletal muscle ° In order to ensure the smooth progress of various metabolism in the body.
Second: fever is often the result of this pair of central dysfunction, all infection, poisoning, dehydration, allergy, endocrine disorders or other physical and chemical factors can cause fever. When fever occurs, the original equilibrium conditions of the body are disturbed.
Third, the metabolic process accelerates and the heat production increases; At the same time, the consumption of glycogen, lipid brain and protein stored in the body increases, and many harmful metabolites are produced, such as lactic acid, carbon dioxide, adenosine and potassium ion; When fever, the sympathetic nerve is excited and can produce a lot of catecholamines. These substances can cause pain and dilate blood vessels. Blood vessels dilate and stretch the painful peripheral nerves of blood vessels, causing headache.
