My soon to be two year old has the flu and this is the third night that she has had a temp and it started to rise. I tried the wash cloths soaked in apple cider vinegar with one on her tummy and one on her forehead for an hour, but there was no change. It just went up. Then I tried the egg whites. I got some cloth all goopy with the stuff and tried it for an hour reapplying once and there was no change. A tepid bath is what helped her. Now her temp went from over 104 to now it's 99.9. We didn't stay in the bath long. I hope it lasts, but I'm prepared to give her another if I need to! She hates the doctors and having stuff stuck up her butt! Even though most of the remedies didn't work for me, thank you for the ideas. It gave me something to do other than go crazy with worry.
Put the person in a tub of cool lukewarm water for about thirty minutes.
