But according to doctors and dermatologists, that’s probably overkill for most people. Unless you’re doing heavy labor, exercising vigorously, working outdoors or around toxins or otherwise getting excessively dirty or sweaty, a few showers per week is enough for healthy hygiene.
In fact, Robert H. Shmerling, MD of Harvard Health says too frequent showering could actually have some negative effects on your health.
“Normal, healthy skin maintains a layer of oil and a balance of ‘good’ bacteria and other microorganisms,” Dr. Shmerling writes. “Washing and scrubbing removes these, especially if the water is hot.” He shares that removing that protective layer can make our skin dry, irritated or itchy, which can lead to damage that allows allergens and bacteria to cross the skin barrier. Additionally, our immune systems require exposure to microorganisms, dirt, and other environmental stimuli in order to create “immune memory,” and if we wash them away too frequently, we might be inhibiting the effectiveness of our immune system.
