Using an Automatic Hand Dryer on Shabbat

Using an Automatic Hand Dryer on Shabbat
Day: Monday
Date: May 11, 2015
Parshat: Behar/Behukotai
Yalkut Yosef: 326

On Shabbat a person should not bathe in cold water and then stand next to a heater while still wet. By warming up the water on him it is as if he has bathed in warm water. However, it is permissible to put one's hands next to a heater to dry them, since he would even be allowed to wash them with warm water. Therefore, an automatic hand dryer may be used on Shabbat if it was on from before Shabbat or if a non Jew turned it on to use for himself and left it on. The hand dryer may be used whether it blows cold or even hot air. A person with a stomachache may put a hot water bottle on his stomach if the bottle is closed well. There is a concern that he may end up using the hot water to wash himself and therefore, without a cover, it is prohibited. It should be noted that even during the week, due to danger, one may not use such a water bottle if the water is extremely hot.
