At six in the morning, there’s a certain quiet inside a public pool. The lifeguard drinks coffee from a paper cup, the fluorescent lights hum, and a man in a frayed swim cap pushes off the wall close to lane four as if he’s done it a thousand times. Most likely, he has. It’s difficult to ignore how content and unhurried everyone seems as you watch this play out. No one is filming. No one has a heart-rate monitor fastened to their bicep. All they do is swim.
It was a specialized scene once. It isn’t these days. Long regarded as the more subdued sibling of cycling and running, swimming has been rising in popularity in a way that even pool operators find surprising. Approximately 4.7 million adults in England swim at least twice a month, making it the fifth most popular physical activity. The numbers fluctuated for a few years, and after 2016, there was a significant decline. The recovery has been remarkable, and it coincides with a larger cultural shift that few anticipated: a desire for solitary, screen-free exercise.
It’s possible that the pandemic changed our perception of exercise in an irreversible way. The moment gyms reopened, they began to feel packed and showy once more. Many people, particularly those over thirty, never returned, but group classes did return with their thumping playlists. Speaking with regulars at any recreation center, it seems that swimming provides a kind of forced stillness even while you’re moving that the treadmill just cannot. Underwater, you can’t check your phone. Doomscrolling is not possible. You can buy an hour back with the water.

Conveniently, the science continues to favor swimming. Under the direction of Professor Hiro Tanaka, researchers at the University of Texas have spent years demonstrating that even three months of consistent swimming can soften stiff arteries the kind of stiffness that silently harms the kidneys and brain long before anyone notices. Swimmers simply outlived their sedentary peers by a significant margin, according to a different, much larger study from South Carolina that tracked over 40,000 men for an average of thirteen years. Although none of this information is particularly new, it is becoming more widely known than it was ten years ago.
What’s more intriguing and a little unsettling is what swimming appears to do to the brain. Blood travels to the head in a different way when you’re upright on a bike or pavement than when you’re horizontal, supine, prone, face-down, or face-up, as most strokes involve. Even Nordic walking in the shallow end, poles and all, has been tested in Tanaka’s lab, and quantifiable improvements in cognitive function have been observed. The image has a slightly ridiculous quality. Additionally, there is an indisputable aspect to the outcome.
The explanations become more intimate when you converse with people at the pool. A Sport England researcher was informed by a retired Birmingham teacher that swimming was the only activity that made her tinnitus go away. It was the first exercise that didn’t hurt him, according to a man recuperating from a knee replacement. Since adolescent swim rates are still frighteningly low, one of the few teenagers said the pool was the only place she wasn’t being watched. Every tale is brief. Together, they start to explain why the lanes are getting congested.
The majority of the work appears to be done by the sport’s solitary nature. Of course, running is also solitary, but it takes place in public, on the streets, in front of cars, dogs, and other people with opinions. You are hidden when you swim. You’re breathing in rhythms that only you can hear while submerged and somewhat anonymous. Anonymity seems like a minor radical act to a generation that is growing more wary of the optimization culture that records, ranks, and shares every workout.
To its credit, the leisure sector has taken notice. No single intervention can change a pool’s popularity, according to Sport England’s swim pilot program, which was implemented in twelve locations. Better changing areas, more compassionate introductory classes, and outreach to women and swimmers with disabilities who had been silently excluded for years are examples of what works: patience. It appears that the lesson is that hospitality is more important for swimming than reinvention.
Another question is whether the boom will continue. The gains could be reversed by pool closures, growing energy costs, and the ongoing lack of swim instructors. Nevertheless, you get the impression that this isn’t a passing trend when you pass a pool window on a winter morning and observe the steam rising off the water. People are choosing it consciously, frequently in silence, and frequently by themselves. Perhaps that’s the point.
