US Doctor's 5-Year Shower Experiment: What Happens When You Let Skin Self-Regulate

Dr. James Hamblin, an author and preventive medicine physician, set out to challenge widely accepted beliefs about hygiene in Clean: The New Science of Skin. The author conducted an unconventional experiment by not showering daily for five years to examine whether daily washing is truly necessary for the health of the individual and not just a social norm. Over time, he observed how his body adapted to the absence of regular soap and water routines.

Naturally, many were curious about whether he developed an unpleasant odor. Hamblin acknowledged that while discussing personal hygiene in such detail was unusual, he did not entirely abandon cleanliness. He continued washing his hands with soap, occasionally wet his hair, and rinsed off when visibly dirty. His goal was to determine if conventional hygiene habits were more about appearance and comfort rather than genuine health benefits.

During an interview, Hamblin explained that most personal care products are designed not just for cleanliness but also for aesthetic appeal, fragrance, and texture. While soap effectively removes dirt and oil, he emphasized that simple rinsing with water and rubbing hands together plays a significant role in eliminating germs.

Hamblin further highlighted that showering with hot water and soap disrupts the skin’s natural oils and microbiome—a collection of microorganisms that live on the skin, similar to gut bacteria. These microbes contribute to skin health and overall well-being, but excessive washing can strip away beneficial bacteria, potentially weakening the body's natural defenses.

Although research on the skin microbiome is still developing, early studies suggest that maintaining microbial balance is more crucial than previously understood. Hamblin likened frequent showering to deforestation, arguing that disrupting the skin’s ecosystem may not always be beneficial.

He also made an important distinction between hygiene and bathing. By having good hygiene, we can prevent the spread of diseases; cleaning our hands after using the bathroom or covering our sneezes are a few examples. Bathing, however, is largely about feeling fresh and socially acceptable rather than directly influencing health.

"It's not about health," Hamblin explained. While some prefer fewer showers, others enjoy long, luxurious ones. Ultimately, he emphasized, bathing frequency should be a personal choice rather than a rigid necessity dictated by societal expectations.

The broader question Hamblin raises is whether daily showers are truly essential or if they are habits shaped by social norms and the booming personal care industry, which has grown into a multibillion-dollar market. His experiment challenges the traditional belief that more washing equates to better hygiene, instead advocating for a balanced approach that respects the skin’s natural processes while considering both scientific findings and individual comfort.
