Fever is a phenomenon that we often encounter in our daily life. When people are sick, fever seems to be an inevitable part. So, why do people get fever when they are sick?This article will unveil the mystery behind the development of burning.
First, we'll understand the definition of fever. Fever, or an increase in body temperature, is a response of the body's immune system in response to an invasion of a pathogen. When the body is stimulated by something like infection or inflammation, the immune system releases white blood cells and chemicals to fight pathogens. These white blood cells and chemicals interact in the body, causing an increase in body temperature, which helps destroy pathogens.
So, why is fever good for the human body?First of all, fever can boost the function of the immune system. An increase in body temperature can promote the activity and reproduction of white blood cells and improve the immune system's defenses. Second, fever can inhibit the growth and reproduction of pathogens. An increase in body temperature can disrupt the living environment of pathogens, making it difficult for them to survive and reproduce in the body. In addition, fever can also boost the body's metabolism and accelerate the body's absorption and utilization of nutrients.
However, fever is not a disease in itself, but one of the symptoms of the disease. There are many causes of fever, including infection, inflammation, allergies, tumors, etc. For example, when the body is infected by bacteria, white blood cells release chemicals that cause body temperature to rise;When the body is infected by a virus, the immune system fights the virus by regulating its body temperature.
How should we deal with a fever?First, if the body temperature is too high, fever reducers can be used to lower the body temperature. However, it should be noted that antipyretics can only relieve the symptoms, not the disease itself. Second, maintain adequate water intake to avoid dehydration. In addition, it is necessary to avoid overexertion and tension so as not to aggravate the condition.
In conclusion, fever is a response of the body's immune system in response to an invasion of a pathogen. Although fever itself is not a disease, it is one of the symptoms of the disease. When faced with a fever, we should stay calm and take appropriate measures to relieve the symptoms. At the same time, it is necessary to actively ** the primary disease in order to completely ** the disease.
