A fever that lasts overnight, if the temperature does not rise too high, does not affect the body in a particularly significant way and does not burn the body. The effect on the body can be a depletion of water, or there can be a significant weakness or generalized muscle pain, etc.. If the body temperature rises relatively high, reached 39 ℃ or 40 ℃, a day and night body temperature can not be reduced to normal, the body uncomfortable feeling will be very obvious, the next morning will not only have a large amount of water consumption, but also have a particularly noticeable discomfort, such as generalized muscle aches and pains, joint pains, and symptoms of fatigue, but generally does not cause particularly serious destructive effects on the body, but only the physical exertion will be relatively large. Therefore, appropriate antipyretic drugs should also be applied to prevent the body temperature from staying too high and for too long. Oral ibuprofen or acetaminophen can be given, or rectal medication can be chosen if there is significant nausea and vomiting and the medication cannot be consumed. If the inflammatory response is particularly pronounced, glucocorticoids can also be applied appropriately for some appropriate conditions.
