Why fewer people are showering daily – and what they're doing instead

A new high-tech capsule from Japan may help explain why.

In plenty of homes, the shower is no longer an everyday ritual. Look a little closer and it becomes clear this shift is about more than convenience: as people juggle saving energy, protecting skin health and experimenting with futuristic washing capsules, our idea of what “proper” body hygiene looks like is changing fast.

Showering less: trend, stopgap, or a healthier routine?

For years, daily showering was treated as the default. If you didn’t do it, you could quickly be judged as unhygienic. That assumption is now starting to fade. Dermatologists are warning about over-washing, energy bills keep rising, water feels like an increasingly precious resource-and, at the same time, new technologies are appearing that rethink hygiene from the ground up.

Younger people in particular are questioning the old “straight into the shower every morning” pattern. Many now use shower gel every other day, and some even less often. In its place: flannels, aluminium-free deodorant, dry shampoo, or a quick wash at the basin.

The body needs cleaning - but not necessarily a full head-to-toe shower every single day.

People who shower less often usually have several reasons at once:

• Skin becomes irritated by daily hot water and harsh surfactants
  
• Gas and electricity prices make long showers feel like a luxury
  
• Awareness of water use and resource consumption is growing
  
• Homeworking reduces the social pressure to look “fresh” at all times
  

High-tech instead of a towel: Japan’s “washing machine for humans”

Alongside this wider move towards showering less, a company in Osaka is pursuing a far more radical idea: washing in something like a human washing machine. The technology has the futuristic name Mirai Ningen Sentakuki, which roughly translates as “washing machine for the human of the future”.

In practical terms, it is a sealed capsule that a person sits inside. The body is washed in about 15 minutes, then dried immediately afterwards-without the user needing to do anything.

Mirai Ningen Sentakuki high-tech washing capsule: how it works in detail

The system brings several components together:

• Sealed capsule: the user stays seated in a pod-like enclosure throughout the entire cycle.
  
• Microbubble technology: extremely fine air-and-water bubbles surround the skin, loosening dirt, sebum and dead skin cells.
  
• No scrubbing: the cleaning is gentle enough that mechanical rubbing is largely unnecessary.
  
• Drying system: once the wash ends, a built-in drying module takes over-much like a tumble dryer, but for people.
  

The promise is straightforward: maximum comfort paired with a more skin-friendly wash. People with sensitive skin-or those with limited mobility-could benefit most from not having to scrub, reach awkward areas or manage a full shower routine unaided.

A further implication is worth noting: if a sealed, automated process can deliver an acceptable clean with less effort, it may reinforce the broader cultural drift away from daily showering-especially in households already watching water and energy use carefully.

AI in the bathroom: when the shower knows your pulse

The real trick behind the Japanese invention isn’t only the washing mechanism, but the digital control that sits behind it. The capsule is fitted with sensors that capture various body measurements.

These include, for example:

• Heart rate
  

That level of monitoring also raises an additional, modern concern: data privacy. Any system that measures bodily signals needs clear rules around what is stored, how it is used, and who can access it-particularly if such technology ever becomes connected, app-controlled or linked to user profiles.
