Our neighborhood pool was scheduled to open on Cinco de Mayo. Emails went out, themed cups were ordered, and some of us even dusted off our pool floats in anticipation. But May 5 came and went, and the gate stayed locked. Turns out, the grand opening got pushed to Memorial Day. This was disappointing. I had looked forward to soaking in the water and swimming some laps. There is just something about swimming and being in the water that relaxes me. It turns out that I am not alone. Science tells us the pool isn’t just pleasure. It’s medicine.

Swimming laps is a great cardiovascular exercise that can improve our physical health and longevity. But the water can also have miraculous effects on our minds. Studies have shown that that water and swimming can heal us.

Stress melts faster than ice in a mojito: Even viewing water for just two minutes—without even getting in—can lower blood pressure and heart rate more reliably than looking at grass or trees. So next time your desk is buried under unread legal memos or discovery responses, take a moment by the pool or head to the coast. Your brain and your blood pressure will thank you.

Swimming boosts memory: In one study, scientists trained rats to swim laps and saw a measurable reduction in memory errors after just one week. Humans show similar results. Kids recall more words after swimming, and older adults improve attention and mental speed. So maybe finalize that contract after a few laps. 

Mood-lifting meets brain-building: Outdoor swimming combines nature, movement, and a sense of autonomy, creating what researchers call an emotional “turbocharge.” Regular swimming also fosters neurogenesis and releases mood-stabilizing serotonin. In fact, it beats walking when it comes to lifting mild anxiety and depression. That’s not just self-care. That’s a smart strategy.

I grew up spending a lot of time in, around, and under the water. I was a competitive swimmer from the age of seven and have been an avid fisherman since I was four-years old. The water feels natural to me. However, I must acknowledge that some people do not have a natural affinity for water. For some, being in any body of water can bring discomfort and even panic. For those of you who struggle with this discomfort, you can find similar mental health benefits simply by being out in nature. Numerous studies have shown that a walk in the woods can improve your mental health and induce a state of relaxation. So, whether it is in the water or in the woods, take time to get out of your office and into nature.
