The reduction of appetite actually saves a lot of energy to accelerate the immune response. Slade said: "Digesting food also requires energy, so not eating will save a lot of energy and help us fight diseases.
Loss of appetite may be good for your health in the short term, but if you need to fight against diseases (such as cancer) for a long time, loss of appetite will cause weight loss, which is not conducive to your health. "
Extended data:
Fever refers to the situation that pyrogen directly acts on the thermoregulatory center, and the thermoregulatory center is dysfunctional or causes excessive heat production and reduced heat dissipation, resulting in an increase in body temperature beyond the normal range.
A cold and fever have both advantages and disadvantages for human body. When you have a fever, the immune function is obviously enhanced, which is conducive to eliminating pathogens and promoting disease recovery. Therefore, if the temperature is not too high, there is no need to use antipyretics, just pay close attention to the temperature change. When the temperature exceeds 38.5 degrees, take antipyretics in time.
Prevention of colds:
First, increase or decrease clothes in time.
Change clothes in time according to the ambient temperature to keep the body temperature normal.
Second, do "cold" exercise.
Washing your face with cold water can stimulate skin blood vessels and enhance your ability to resist cold and prevent diseases.
Third, the nutrition should be balanced.
Whether the immunoglobulin content in human body is sufficient is one of the factors that affect immune function. Without immunoglobulin, the body's ability to resist bacteria or viruses will decline. Fish, meat, eggs, milk and bean products have high nutritional value, so attention should be paid to food intake to strengthen the comprehensive utilization of protein. In addition, taking vitamin C and foods rich in vitamin C also has a certain preventive effect.
Fourth, exercise more.
Physical exercise and nutritional balance are equally important, so we should do more exercise, such as running and doing exercises. Walking outdoors in the morning and evening and breathing fresh air can enhance blood circulation, improve physical fitness and improve immune function.
Fifth, improve immunity.
Modern medical research shows that low immunity is the root cause of recurrent illness. Therefore, we must use efficient and safe means to fundamentally enhance immunity in order to completely get rid of the harm caused by repeated illness. Zinc supplementation can improve immunity and eat more zinc-supplemented foods, such as seafood, melon seeds and walnuts.
