fever is a common resistance of the body & ldquo; Foreign invasion & rdquo; Cold and fever are not comfortable, but some people don’t have a fever for a long time and worry about whether they will have a big problem, and & ldquo; If you don’t catch a cold for a long time, you are prone to serious diseases & rdquo; This statement. These people believe that colds can cause the response of the body’s immune system. Regular colds, like regular fitness, can enhance the disease resistance of the immune system, so it is not easy to get seriously ill; On the contrary, if you don’t catch a cold often, your immune system is weak and you are prone to serious diseases. Let’s take a look with you.
Fever is actually initiated by the human body to protect our mechanisms. When we are infected by foreign viruses and bacteria, the body will quickly mobilize the body’s immune system to kill foreign bacteria and viruses.
generally, microorganisms with small quantity, little harm or weak activity will be quickly eliminated by the immune system and will not cause any harm to the body.
when the pathogen is too strong or the body’s resistance decreases, the immune system fails to kill in time & ldquo; Foreign invaders & rdquo;, You’ll catch a cold. Therefore, the body needs to mobilize more powerful forces to eliminate it. In the process of mobilizing more powerful forces, people need higher body temperature, so people begin to have a fever.
however, the fever caused by a cold is only accepted by our immune system for a specific cold virus & ldquo; Training & rdquo;, Cold viruses change very fast, so even if they form immunity, they can’t prevent the next cold, let alone fight other viruses, bacteria, including cancer cells.
therefore, what really makes the human body fever is the foreign invaders rejected by the immune system. The increase of body temperature is only a sign of the body’s struggle with pathogens. For the body of normal adults, after killing foreign pathogens, the body temperature will naturally drop.
people who often catch a cold and have a fever are not how strong the immune system is. On the contrary, it just shows that the body’s immune system has poor reactivity and can’t eliminate germs and viruses at the first time. They also need to mobilize immunity through fever, so they are more likely to get sick.
in addition, many serious diseases such as leukemia and parasitic infection will produce fever in the early stage, so fever is not always a good thing.
what to eat for a cold and fever
among the three kinds of food: protein, fat and carbohydrates, a high-fat diet is certainly not good, because there is less digestive juice secretion after a cold and it is difficult to digest after eating. The best protein foods are eggs and milk (or yogurt). Eggs can be made into boiled eggs, steamed egg soup with milk, poached eggs with fermented rice, etc.
carbohydrate food is the simplest food when you have a cold and fever. You can choose watermelon, Sydney, apple, kiwi fruit, orange and other fruits to eat. You can squeeze juice and drink if you have a sore throat. If the throat is red and swollen, in addition to Lily medlar millet porridge, Lily Sydney Water and fresh sugarcane juice are also more suitable. After high fever and sweating a lot, if you don’t eat or drink, it is easy to lead to electrolyte disorder. It’s best to eat some watermelon or drink some fresh watermelon juice first. They can help reduce fever, supplement body fluid, reduce swelling and benefit water.
The diet principle of fever
because the first job of cold fever is to reduce the fever naturally. No matter what form of fever reduction method, the fever can be reduced only after sweating naturally. Therefore, you should supplement more water. To make the cold recover as soon as possible. Drink plenty of water when you have a cold and fever. Eat something light, such as porridge. Don’t eat greasy, big fish and meat. Sleep more. Just cover the quilt and sleep with sweat.
when you have a cold and fever, cook some white porridge and buy a kilo of fresh mushrooms. The thin meat is better. Only put water and a little salt. After boiling, simmer over a low fire for 15 minutes. Drink soup while it is hot. You can’t eat spicy mushrooms. When people have a fever, they consume more energy and have weak resistance, so they need to supplement some nutrition. Many diseases can cause fever, which is a defensive reaction when they are ill. When a person has a fever, due to the increase of body temperature, the decrease of body immunity and the decline of gastrointestinal digestion and absorption function, the contradiction between the increase of nutritional consumption and the weakening of digestive function will occur when a person has a fever.
No food for fever
eggs: eggs are indeed rich in nutrition, but it is not suitable to eat more eggs during fever, because the protein in eggs will produce certain additional calories after decomposition in the body, increasing the body’s calories, Aggravate fever symptoms, prolong fever time and increase patients’ pain.
drinking tea: drinking strong tea will keep the brain excited, speed up the pulse and raise the blood pressure, so as to raise the patient’s body temperature and irritability. At the same time, tea water will affect the decomposition and absorption of drugs and reduce the curative effect of drugs.
drink cold drinks: if the fever is caused by infectious diseases such as bacillary dysentery caused by unclean food and the function of gastrointestinal tract decreases, drinking more cold drinks will aggravate the condition, even worsen the condition and endanger life.
honey: during fever, it should mainly clear away heat and should not be nourishing. Honey is a tonic for replenishing qi. If you take more honey, the internal heat of patients will not be well cleaned up and eliminated, and it is easy to be complicated with other diseases.
spicy: due to the increase of body temperature and vigorous metabolism in the body, eating warm and spicy foods such as ginger, garlic and pepper will help heat and aggravate the condition, which is not conducive to antipyretic and early recovery.
forced eating: when some children have a fever, parents often think that the fever consumes nutrition, especially if they don’t eat. Therefore, they force their children to eat, and some try their best to give their children high nutritional food. In fact, this practice is counterproductive. It can not only promote appetite, but also turn off appetite, and even cause vomiting and diarrhea, aggravating the condition.
