Bread can be eaten in moderation during fever according to one’s own situation, but bread cannot be used to reduce fever. Fever refers to a pathologically elevated body temperature, usually the body temperature of 37.3-38 ℃ for low fever, 38.1-39 ℃ for moderate fever, 39.1-40 ℃ for high fever, more than 40 ℃ for ultra-high fever. During the period of fever, the consumption of bread is conducive to replenish the body with some carbohydrates, proteins, fats and other nutrients, and has no special effect on fever, so you can eat bread in moderation when you have a fever, but the bread has no antipyretic effect. During the period of high fever, cold and lukewarm water can be used to reduce the temperature physically, or oral ibuprofen granules, acetaminophen tablets and other drugs to reduce fever. If fever symptoms occur, if the physical cooling is ineffective, you should seek medical treatment in time to prevent the condition from worsening. It should be noted that during the period of fever, more water will be consumed, so attention should be paid to the intake of water.
