Applying sanitizer to your hands feels cool because the alcohol in it evaporates quickly. As the alcohol evaporates, it absorbs heat from your skin, creating a cooling sensation. This is similar to how water evaporating can cool a surface. The rapid evaporation of the sanitizer’s alcohol is what makes your hands feel cooler as it dries. This cooling effect is a result of the heat energy being used for the evaporation process.
