  • Simply put, the body doesn't burn as many calories when you sleep. Calories burned equals heat among other things.
  • Your body surfaces radiate energy in the infrared wave lengths. If you are uncovered (to me that means not only do you have no blankets or top sheet but you also are naked)and the air temperature in the room is less than your bodies surface temperature, you will be losing more heat to the air that you will be gaining from the air. Your calm and relatively quiet body will not be generating nearly as much internal heat as it does when you are active so you will experience a net heat loss. Furthermore, any moisture that manages to get to your skin's surface in the form of perspiration will not be evident because it will evaporate quickly unless the air in the room is extremely humid to begin with. But, so long as the air in the room has a relative humidity of less than 100% you will be losing more heat (via evaporation) than you will be gaining by condensation of moisture from the air on to your skin. Evaporation is a cooling process (as in the AC evaporator) so in nearly all cases your body surface will be cooling by evaporation of liquid water (which you will not see or feel) from your skin. Summary: You will be losing more heat by radiation of infrared and evaporation of moisture from your skin than you will be gaining from the air around you and/or the internal heat that your body is generating.
