In general, the temperature of the human body is 37 degrees Celsius, but it can sometimes reach more or less a degree and the person has a fever when the body temperature reaches 38.3 degrees Celsius or higher, and can increase the temperature of the human body due to: A lot of things, but what's going on in the body in this case?
A high body temperature is a protective mechanism of the body responsible for the disease.When bacteria or viruses attack the body, the immune system produces a substance called pyrogen.
This substance is transported by the blood to the brain, affecting an area called hypothalamus, specialized in the regulation of body temperature.
The fever-causing substance blocks heat-sensitive neurons and, in turn, elevates those who are sensitive to cold, causing misleading messages in the hypothalamus region indicating that the body is naturally colder. .
High body temperature helps to fight the cause of the disease, stimulating the movement and work of white blood cells and increasing the secretion of antibodies in the body. On the other hand, the high body temperature kills or inhibits the growth of certain types of bacteria and viruses, thus protecting you from the disease.
If body temperature increases, it means:
– Blood and urine volume is reduced due to low water content due to excessive sweating
– The proteins in the body break down faster than usual, resulting in increased secretion of nitrogen products in the urine.
– When body temperature continues to rise, the person will feel chills and tremors, while she will warm up and her skin will be wet if the temperature drops quickly.
