why when you have a fever, it's lower in the morning and rises in the evening?

Answer 1

I must admit I've always been curious about this too. I can understand that one's body temp is lower when they first rise in the a.m.. But the fever always seems to come on late in the evening. This was always the case with my kids.

Hi, Did you give him medicine prescribed by your pediatrician or something purchased over the counter? If you've already taken him to the doctor and been given medication for him, the doctor should have told you what to expect, but.... Although a fever of 102 isn't all that unusual in a young child and isn't as dangerous as some people believe, there is a great possibility that it will go higher. If you have already given him tylenol, you might try giving him a bath in a tepid tub, not too warm but definately not too cold either, playing in the bath is usually something a child that age loves to do anyway. When you get him out of the tub, make sure to dry him off really well, but don't overdress him. As adults we sometimes think we have to bundle up our feverish babies, while in truth overdressing will cause the body to retain too much heat and the fever will last longer. If his temperature doesn't go down a bit, after the bath, I'd suggest calling your pediatrician and asking if it's ok to give him some baby asprin. If his temperature goes up or he starts to act differently you may consider taking him to the ER, but that's usually very frightening for a child. Remember most temperatures do go up in the evening. If his temperature is still that high in the morning I'd definately take him to the doctor. Not so much a concern for the 102 fever, as the length of time he will have had that high of a temperature. Good Luck.....Give him a big hug and kiss.

I think it has to do with the fact that while we are sleeping, our bodies have the chance to rest. When we are awake we are exerting ourselves more and our bodies have to work that much harder to keep us going and to heal from whatever is causing the fever. When we rest, our bodies don't have to work quite so hard because it takes less energy to sleep.
