The first thing to do about it is to take a shower or bath, then pat dry with a towel. Here are some other ways that you can help yourself feel less hot and sweaty at night:
Remove bed clothes so you can let your skin breathe. If the air in your room is too warm, remove all of the bedclothes except for boxers or briefs (or even pajamas), so that they act as an insulator between your skin and the rest of the room. Consider making sure there’s no light shining directly on your body (especially if you’re sleeping naked) by covering windows with curtains or blinds. Otherwise, try turning off lights in rooms where you sleep; this will reduce indoor heat buildup during daytime hours when lights are on but not used. Be friendly toward yourself—take regular breaks from work! Use fans instead of air conditioning (this may be difficult if it’s summertime). Put cool-mist vaporizers near beds to make them more comfortable; otherwise, use complementary products like evaporative coolers filled with water-filled bottles or bowls full of ice cubes placed strategically around bedroom areas; these items draw out moisture from human bodies and provide relief from sweating at night (and during day time activities such as exercise). Also consider taking melatonin supplements before going to bed for maximum comfortability during undesirable conditions such as excessive sweating due to hot temperatures or high humidity levels occurring indoors.
