Showering cleans the skin and removes dead skin cells to help clear the pores and allow the skin cells to function. It washes away bacteria and other irritants that could cause rashes and other skin problems. The main difference between bath and shower is that bath means soaking your body in a tub filled with water to clean yourself, while shower means standing under a spray of water to clean yourself. However, people often use the terms bath and shower interchangeably, misinterpreting the actual meaning of the terminology.
