To fully maximize the benefits of a luxurious sauna bath, it is important for a person to be careful of what he or she eats. If you have just eaten dinner, then be sure to wait at least one hour before going into the sauna bath. Going into a sauna bath on a full stomach can leave one feeling tired and nauseous. Also, try not to consume any Alcoholic Beverages before going into a sauna bath. You should simply try to eat light before a sauna bath and drink lots of water. Experts recommend drinking as much water as possible before a sauna bath.
