Say I’ve been active outdoors on an extremely hot day, and I take a shower afterward. When I finish, I have three choices: (1) Briefly run the water hotter to open my pores, (2) run it colder to close them or (3) just step out and dry off. Which action is best to bring down my core temperature?
—Ken Long, Wilmington, N.C. Contrary to popular belief, pores do not open or close, so you can do whatever makes you feel most comfortable. One note of caution: Some people say that in hot weather you should take a hot shower (not just briefly run the water hotter) to cool off a hot body. This is worse than wrong: It may raise your body temperature dangerously high.
