Washing myths busted: Daily showers may harm skin's natural barrier

Many people believe they have hygiene rules down pat. However, it turns out that commonly accepted rules may not be the best. Doctors and scientists indicate that the habit of daily washing of the entire body is not the healthiest choice.

A dermatologist and author of the book "Beyond Soap," spoke on washing. Dr. Sandra Skotnicki from Yale School of Medicine noted that during body washing, a special protective layer of the skin called the hydrolipid barrier, is removed.

This layer consists of natural oils and substances secreted by the skin, which protect the body from bacteria, viruses, and other potentially harmful factors.

Too frequent or too long washing can reduce the protection of our entire body and dry out our skin. As a result, it can cause irritation, damage, excessive flaking, and itching.

Scientists are increasingly pointing out that the human body should come into contact with microorganisms and dirt. This is because contact with various microorganisms helps the immune system learn how to respond correctly.

Scientists emphasize that washing once every 2-3 days is fine. Doing so in the evening hours is recommended to avoid bringing dirt and sweat to bed.

However, some parts of the body need to be washed every day. This concerns the armpits, feet, and intimate areas.

This is due to the higher tendency to accumulate fungi and bacteria and to emit unpleasant odors. These body parts should be washed daily with soap, gel, or another suitable product. The remaining parts can be rinsed with water.
