Gen Z worries about climate but takes 15-minute showers daily

Gen Z leads the pack on climate worry, yet their shower habits tell a different story. New research reveals that more than half of people aged 18 to 29 spend at least 10 minutes under the tap every single day. That duration can drain up to 150 litres of water in one wash. Picture filling around 750 standard drinking glasses with that volume alone. The contradiction is stark for a group raised on warnings about droughts and climate collapse.

Dr Pablo Pereira-Doel, an environmental scientist at the University of Surrey, told the Daily Mail that three minutes is enough to clean your body. Add two more minutes if you wash your hair, and you hit around five minutes total. That window includes time for enjoying the warm spray. There is little scientific reason to linger beyond that mark.

The poll from Let's Save Water surveyed 2,000 British people across all age groups. The numbers show a clear drop-off as age increases. Fifty-two per cent of those aged 18-29 took showers lasting at least 10 minutes. That figure fell to 39 per cent for Millennials between 30 and 45. Only 28 per cent of Gen Xers, aged 46 to 61, admitted to the same habit. Women were more likely than men to take extended showers. Twenty-seven per cent of women said they showered for over 10 minutes daily, compared with 19 per cent of men.

A spokesman for Let's Save Water noted that drought conditions this summer have brought renewed focus on water scarcity. The group is reinforcing a simple message: water is precious and we must use less. On average, adults believe they consume around 30 litres of water daily. The true figure sits closer to 140 litres. The research highlights the generational divide, with Gen Z most likely to have showers longer than 10 minutes.

In the UK, household showers last around 7.5 minutes on average according to Dr Pereira-Doel. Other studies show people regularly run them for much longer. Some individuals spend close to 40 minutes under the stream. Getting clean isn't always the point, he explained. Over four in 10 showers in the sample served purposes unrelated to hygiene: relaxation, self-care, or warming up on a cold morning. When a shower fills that role, its length becomes an unconscious decision rather than a calculated choice.

Living in soft water areas changes the equation. People there shower around a fifth longer than those in hard water zones. The likely explanation is that shampoo lathers more richly and rinses easier in soft water. That makes the experience feel better, so people linger. Morning showers also tend to be shorter because most people have somewhere they need to be. Evening or weekend showers face fewer time constraints. Low water pressure can extend the duration too. People may compensate for a weak spray by staying in longer to ensure they feel properly rinsed.
