Cold fever is caused by the body’s release of endotoxin after a viral infection, which produces an endogenous pyrogen that acts on the hypothalamic temperature center to shift the thermoregulatory point upward and cause fever.
Most colds and fevers are caused by viral infections. It releases a lot of endotoxin in the body, which acts on the hypothalamus thermoregulatory center to shift its regulation point upward, so the body’s heat production increases and heat dissipation decreases, resulting in an elevation of body temperature above the normal range.
Fever is a self-protection symptom, indicating that the body’s macrophages, white blood cells and other viruses are fighting with the virus, and at the same time make the cold virus intolerant of high temperatures become weaker, to enhance the body’s immunity, the purpose of removing pathogens.
