Generally speaking, 37℃ is not considered a low fever. A low fever is defined as 37.3℃-38.5℃, and 37℃ is at most a precursor before a low fever. First of all, you can rest in bed, keep the indoor environment quiet, moderate temperature, good ventilation, and the clothes should not be too thick. If you sweat a lot, change clean clothes and wipe your body with warm water in time. Generally speaking, when the body temperature rises to 38.5℃, you can take antipyretic drugs to lower the body temperature. It is recommended to take them strictly in accordance with the dosage provided by the doctor to prevent major side effects. Normally, you should pay attention to drink more water. When you have a fever, you breathe faster and evaporate more water. Drinking more water can also promote more urination, through which cooling and excretion of toxins can be achieved. In terms of diet, we should also pay attention to the fact that fever accelerates metabolism and increases the consumption of nutrients, while the water in the body is also significantly consumed. At the same time, the secretion of digestive juices decreases during fever, and gastrointestinal motility slows down, so the diet should be easy to digest and light.
