Which Body Part Needs To Be Washed Daily?

We hear it all the time: hygiene is a priority. Regular showers, thorough scrubbing, and using an abundance of soaps or gels seem like the key to staying fresh and healthy. However, some experts suggest we could be doing more harm than good. A growing body of research indicates that our obsession with cleanliness might disrupt the body’s natural processes and leave us vulnerable to skin issues.

Our Skin’s Hidden Ecosystem

To understand why over-washing is problematic, we must first recognize that our skin isn’t simply a barrier – it’s a thriving community. Billions of microscopic organisms, collectively known as the skin microbiome, reside on the surface of our skin. This invisible ecosystem is comprised mainly of bacteria, along with some fungi and viruses. Before you worry – most of these microbes are beneficial or, at the very least, harmless.

The Importance of Skin Bacteria

Our helpful skin bacteria perform crucial functions such as:

  • Protection: They create a slightly acidic environment that makes it difficult for harmful bacteria to colonize our skin. Think of them as your own personal defense force.
  • Immune System Support: Beneficial bacteria work to prevent pathogens from causing infections, and they even help train the immune system to differentiate between friend and foe.
  • Nutrient Production: Some skin bacteria break down substances on our skin and create beneficial byproducts, including vitamins and other essential nutrients.

How Showering Impacts the Microbiome

When we shower excessively, especially with harsh soaps, we strip away the skin’s natural oils along with both good and bad bacteria. Here’s what happens as a result:

  • Dryness and Irritation: Soaps remove sebum, a natural oil that helps retain moisture. Without it, the skin becomes dry and prone to cracking and irritation.
  • Disrupted Balance: Excessive cleaning disrupts the delicate equilibrium of the skin’s microbiome. This can allow harmful bacteria to gain a foothold, increasing the risk of infection.
  • Increased Sensitivity: Overly cleansed skin lacks the protective barrier it needs, leading to increased sensitivity and potential inflammation.

The 3-Part Shower Routine

Dr. Sandy Skotnicki, a renowned dermatologist, emphasizes that regular, full-body showers aren’t necessary. According to experts, focusing on three key areas is sufficient:

  1. Armpits: Our armpits have a high concentration of sweat glands, generating the perfect moist environment for bacteria to flourish. Washing armpits with a gentle soap helps get rid of sweat and reduces odor-causing bacteria.
  2. Groin: Like the armpits, the groin area is naturally more humid, which facilitates bacterial growth. Daily cleaning helps prevent skin irritation, infections, and unwanted odors.
  3. Feet: Our feet are prone to sweating, and getting sweaty socks can also worsen odor. Thorough washing helps neutralize foot odor and prevent conditions such as athlete’s foot.

How Often Should You Shower?

The most suitable showering frequency depends largely on individual needs and lifestyle. Factors like activity level, climate, and skin type all come into play. In general, most people can benefit from showering every other day or even as seldom as twice a week. Daily rinsing with clean water helps remove surface dirt and sweat without overly impacting the microbiome.

Choosing the Right Soap

If you opt for soap, look for gentle, moisturizing cleansers designed to protect the skin barrier. Fragrance-free options are generally better, as artificial scents can be irritating. For very dry or sensitive skin, using soap only on the three priority areas and skipping it elsewhere may be best.


1. Won’t not showering all over make me smell bad?

Not necessarily. Body odor primarily comes from the breakdown of sweat by bacteria in areas like the armpits. By targeting these specific regions, you eliminate the major source of odor.

2. What if I exercise regularly?

If you have an active lifestyle, you might feel the need to shower more frequently, and that’s completely understandable. A quick rinse with plain water after a workout usually suffices – it washes away sweat without overly stripping the skin. On exercise days, target the 3 key areas with a gentle cleanser followed by your normal water rinse.
