When the body has a fever or even high fever time, you can carry out physical cooling or take some antipyretic drugs, and can not rely solely on fruit to reduce fever. But for fever patients are generally recommended to eat more fresh fruits and vegetables, on the one hand, can replenish a lot of water, on the other hand, can supplement a variety of vitamins (such as vitamin C and vitamin B), conducive to the discharge of toxins in the body. Apples, bananas, cucumbers, kiwis, grapefruits and mangosteens, which are more common in daily life, have the effect of clearing heat and generating fluid, while at the same time replenishing nutritional elements. However, fruits can only play an auxiliary therapeutic role. If the patient’s body temperature exceeds 38.5℃, he needs to take some fever-reducing drugs by mouth, such as compound zinc-cloth granules, acetaminophen or ibuprofen. The specific dosage of medication should be combined with clinical, under the guidance of physicians. In short, when you have a cold and fever, you should eat more fresh vegetables and fruits, eat a light diet, drink more water, avoid spicy, raw and cold. You should also pay more attention to keeping warm, moisturizing, and strengthening exercise to improve your body’s immunity.
