Why More People Are Showering in the Dark, According to Doctors

A shower after a long day can feel like a reward, but some people say there is an easy way to make it even more soothing.

Just switch off the lights.

That may sound unusual, especially for anyone who thinks of showering only as a way to get clean. Still, online users and experts say this small adjustment can offer benefits for both mental and physical well-being.

According to TikTok user Alex, known as simplysanfordco, showering with the lights dimmed can help support the nervous system by reducing nighttime stimulation. She also says it may encourage melatonin production before bed, which can make falling asleep easier.

“Dark showers have become one of my favorite ways to wind down in the evenings. I originally started incorporating them into my nighttime routine as a way to disconnect from the constant stimulation of the day,” Alex tells Newsweek.

“Between the dim lighting, candles and a little time to myself, it's such a simple change that makes an ordinary shower feel more relaxing.”

Nighttime Light Exposure

“Light exposure naturally suppresses melatonin production in the brain making it difficult to fall asleep and stay asleep,” Dr. Chelsie Rohrscheib, a neuroscientist and sleep head researcher at Wesper, tells Newsweek.

Even without changing the lighting, a warm shower at night can already help prepare the body for sleep.

“To initiate sleep, the body naturally lowers its core temperature by approximately 1 degree. Taking a warm shower temporarily raises body temperature followed by a subsequent decline in core temperature after you step out,” Dr. Rohrscheib says.

“This cooling process can help support the body’s natural transition into sleep. Combining a warm shower with dim lighting can therefore support two important sleep-promoting processes simultaneously.”

In warmer or tropical climates, cooler showers may be a better fit.

And the benefits of showering in the dark may not stop there.

Circadian Rhythm

Alex says the practice can also help strengthen circadian rhythm by creating a clearer distinction between day and night.

Circadian rhythm is the 24-hour cycle that tells the body when to wake up and when to sleep. It also affects digestion, hormones and body temperature.

“Our circadian rhythm, which regulates when we're awake vs. asleep, is strongly influenced by light exposure. When light enters our eyes, it signals the brain to suppress melatonin, an important hormone that helps prepare the body for sleep,” Dr. Rohrscheib tells Newsweek.

“As light levels decrease in the evening, melatonin production rises, which promotes sleepiness. Showering in dim or low lighting at night can help minimize melatonin suppression, allowing your brain to better prepare for sleep.”

For Alex, though, the appeal is not purely scientific.

“Honestly it just feels good,” she says.

‘I’ve been doing this for years’

Many commenters appear to already be embracing the idea.

“Changed my life,” one user wrote after trying it.

“Showering in the dark is like showering in an outdoor shower under moonlight in nature,” another said.

“It’s the only way I take showers or baths. I’ve been doing this for years!! It’s a must!” a longtime fan of dark bathing added.

For anyone hoping to relax after a busy day, the solution may be simple: turn off the lights the next time you shower.
