Showering: Not cleaning your shower head promotes bacteria that can cause lung infections

“Showering too often can compromise your immune system. While it is important to keep your body clean, showering unnecessarily can be a bad thing.”

According to the pharmacist, your body needs a moderate amount of exposure to dirt and bacteria to strengthen the immune system; this helps to build up a resistance to bacteria that is genuinely harmful and potentially dangerous.

“Over-showering stops the normal exposure of dirt and bacteria, which can make the immune system more sensitive than it needs to be. This can make you more susceptible to illness.”

How often is too often?

Harvard Health says: “While there is no ideal frequency, experts suggest that showering several times per week is plenty for most people.”
