If your forehead is not hot, but your body temperature is high, you have a fever. Body temperature refers to the internal temperature of the human body, not the surface temperature, the forehead temperature belongs to the surface temperature, the surface temperature is easily affected by the environment temperature, can not represent the body temperature. If the fever does not exceed 38.5°C, you can drink more warm water, eat a lighter diet, rest more, avoid strenuous activities, do not need to actively use antipyretic drugs to reduce fever for the time being, test the body temperature regularly, and pay attention to keeping warm if your body is cold. If the body temperature does not drop, more than 38.5°C, or even to 39.5°C or more, to actively intervene, you can take warm water baths to physically lower the temperature, you can also take antipyretic drugs, do not cover too tightly when the body is not cold, cover too tightly is not conducive to outward heat dissipation. The fever is not always caused by bacterial or viral infections, even if the fever is caused by an infection, it is not always caused by a bacterial infection, so don’t eat anti-inflammatory drugs at your own discretion. If it is a viral infection, anti-bacterial anti-inflammatory drugs do not work on viruses, so you should get help from your doctor.
