Besides carrying the risk of burning or damaging your skin, hot water causes vasodilation of the blood vessels. Therefore, you will want to avoid showering or bathing in extremely hot water. It is recommended that you keep the water temperature below 102° F (38.9° C), and your time under 15 minutes. Hypoallergenic soaps can also help prevent irritation of the skin. After showering or bathing, be sure to dry your skin completely, patting the skin gently instead of rubbing, and taking extra care to dry the skin between the toes.
