Gen Z on the Dark Showering Trend

Lights off. Water on. Stress down?

A growing number of Americans are stepping into completely dark showers in hopes of falling asleep faster and easing anxiety. The wellness trend known as “dark showering” has taken off among Gen Z in particular, but the question remains: does it actually work?

To see how widespread it really is and whether it lives up to the sleep hype, we surveyed 1,001 Americans about their experiences, motivations, and results. Here’s what the data reveals about who’s trying it, why they’re doing it, and whether it’s actually helping.

Who’s Actually Trying Dark Showering?

The trend may sound niche, but it’s already reached a surprising number of households. Younger generations, in particular, appear to be leading the movement.

Nearly 1 in 3 Americans (30%) say they have tried dark showering, even though only 29% had previously heard of it as a trend. Among those aware of the trend, 68% say they have tried it.

Gen Z and Millennials lead adoption, with 32% of each generation saying they have tried it, compared to 26% of Gen X and 18% of Baby Boomers.

Adoption is fairly consistent across most income levels, ranging from 28% to 34%, but drops to 20% among households earning $150,000 or more.

Anxiety relief (51%), less overstimulation (44%), and better wind down before bed (35%) are the leading reasons people shower in the dark.

Anxiety relief is highest among Gen Z (56%) and Millennials (53%) compared to Baby Boomers (43%) and Gen X (41%).

Most dark showerers practice the ritual at night, with 25% showering in the evening and 32% doing so right before bed. By comparison, 19% shower in the morning and 4% in the afternoon.

Only 4% of dark showerers started because of TikTok or Instagram.

Does It Actually Improve Sleep?

Beyond curiosity and aesthetics, many people turn to dark showering with a specific goal in mind: better rest. The results suggest that for many, it’s more than just a trend.

Most dark showerers (89%) say they plan to stick with the ritual, and 62% report noticeable sleep improvements, including falling asleep faster (35%) and experiencing fewer racing thoughts before bed (31%).

• About 1 in 6 dark showerers (16%) say the practice replaces their nighttime scrolling habit. Among Gen Z, that rises to nearly 1 in 5 (18%).
• Dark showerers who practice 2-3 times per week report better sleep (57%) than both frequent dark showerers (48%) and non-dark showerers (39%).
• Gen Z dark showerers report stronger sleep effects than older adults, with 39% saying they fall asleep faster compared to 34% of older dark showerers.

Does the Science Support What Our Respondents Reported?

The self-reported results from our survey align with what sleep researchers have found about the two core mechanisms at work.

A 2019Verified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source systematicVerified Source ScienceDirectOne of the largest hubs for research studies and has published over 12 million different trusted resources.View source reviewVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source of 17 studies found that a warm shower taken one to two hours before bed for as little as 10 minutes shortened the time it took to fall asleep by roughly nine minutes and improved overall sleep efficiency.

The key isn’t the warmth itself but the cooling that follows — when you step out of warm water, blood vessels in your hands and feet widen, heat dissipates from the body, and core temperature drops, signaling the brain that sleep is near.

A large-scale 2021 studyVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source of over 1,000 older adults confirmed that this heat-loss effect is what drives the benefit, finding that bathing one to three hours before bed produced measurably greater skin temperature gradients between the hands and feet versus the core — and that higher gradient was directly linked to falling asleep faster.

A 2023 field studyVerified Source National Library of Medicine (NIH)World’s largest medical library, making biomedical data and information more accessible.View source reinforced this further, finding that a larger rise in core temperature during bathing produced a greater temperature drop afterward and significantly shorter sleep onset compared to showering alone.

In other words, the more thoroughly you warm up, the faster you tend to cool down — and the faster that cooling happens, the easier falling asleep becomes.

The Dark Shower Makeover

For some, dark showering doesn’t stop at flipping off the lights. It leads to small, and sometimes bigger, bathroom upgrades.

• Some dark showerers (15%) have remodeled their bathrooms for the ritual, spending an average of $54.
• Gen Z renovators spend an average of $30, while older adults spend nearly double at $58.
• Only 7% of dark showerers have slipped while showering in the dark, but nearly half of renovators (47%) proactively added bath mats or anti-slip flooring.

The most common bathroom modifications include:

• Candles or soft lighting (52%)
• Bath mats (41%)
• Scent diffusers for essential oils or other calming accessories (32%)
• Speakers or ambient sound systems (32%)
• Blackout curtains (25%)
• Dimmable lighting (20%)
• Red lighting (14%)
• Anti-slip flooring (14%)

One upgrade worth prioritizing before any of the others is safety. Complete darkness is not recommended regardless of how comfortable you are in your bathroom. A dim amber or red-toned nightlight gives enough visibility to move safely while still keeping light levels low enough to support melatonin production.

Non-slip mats both inside the shower and on the floor outside it are the single most practical addition before starting the practice, and bath mat adoption among our renovator respondents — at 41% — suggests many dark showerers have already figured this out on their own.

FAQs

What is the best time to take a dark shower for sleep?

The ideal time is one to two hours before bed, which gives your body enough time to warm up during the shower and cool down afterward. That cooling effect is what signals your brain that it’s time to sleep.

What temperature should the water be for a dark shower?

Research suggests water between 104 and 108.5 degrees Fahrenheit works best for sleep benefits. The goal isn’t the heat itself but the drop in body temperature that happens once you step out.

How long should a dark shower last?

About 10 to 15 minutes is enough to get the sleep-promoting benefits of warm water and reduced light exposure. Shorter showers may not give your body temperature enough time to rise and then fall meaningfully afterward.

Should you shower in complete darkness?

Complete darkness isn’t recommended because it raises your risk of slipping or falling on wet surfaces. A dim nightlight or amber-toned bulb gives you enough light to move safely while still supporting melatonin production.

What kind of lighting works best for a dark shower?

Amber or red-toned nightlights are the best option because warm-hued light is less likely to suppress melatonin than the cool white or blue light most bathroom fixtures emit. Avoid bringing in corded lamps, and keep any candles well away from water and flammable materials.

Can you wash your hair during a dark shower?

Yes — shampooing and conditioning work fine by touch and muscle memory in low light. If you’re worried about product mix-ups, organize your bottles by position or texture before dimming the lights.

Does a bath in the dark work better than a shower for sleep?

A full bath may produce a larger rise in core body temperature than a shower, which leads to a steeper temperature drop afterward and potentially faster sleep onset. That said, a warm shower taken one to two hours before bed still meaningfully shortens the time it takes to fall asleep, making it a practical option for most people.

What should you do after a dark shower to protect the benefits?

Keep your home lighting low as you move from the bathroom to your bedroom, and avoid checking your phone or turning on bright overhead lights. Maintaining that dim environment helps carry the melatonin-supporting effect through to the moment you fall asleep.

Do you need special equipment to dark shower?

No special equipment is required — a plug-in amber nightlight costing just a few dollars is enough to get started. A non-slip bath mat inside and outside the shower is the one practical addition worth making before your first attempt.

What the Data Tells Us

Dark showering has moved well past a fleeting social media moment. Nearly 1 in 3 Americans have already tried it, most plan to keep doing it, and the sleep benefits they report align closely with what researchers have found about warm water and evening light exposure.

The science doesn’t require a leap of faith here — dimming the lights and warming up before bed are two of the more straightforward things you can do to help your body transition into sleep, and dark showering combines both in a single routine that costs nothing extra.

That said, no single habit fixes poor sleep on its own. Dark showering works best as part of a broader wind-down — one that includes consistent sleep timing, a cool bedroom, and limited bright light after the shower itself.

For the 62% of our respondents who noticed real improvements, it likely wasn’t the darkness alone doing the work. It was the signal: the day is done, the lights are low, and sleep is next.

Methodology

In 2026, we surveyed 1,001 U.S. adults through CloudResearch Connect. The sample was 54% women and 46% men.

By generation:

• 20% were Gen Z (ages 18–28)
• 50% were Millennials (ages 29–44)
• 22% were Gen X (ages 45–60)
• 8% were Baby Boomers (ages 61+)

Questions about reasons, sleep outcomes, and habits were asked only of respondents who had tried dark showering.

Questions about bathroom renovations and upgrade spend were asked only of those who reported remodeling their bathroom because of the practice.

The margin of error is ±3.1% at a 95% confidence level. As with all survey-based research, responses are self-reported and may be subject to recall or social desirability bias.
