How is swimming good for our brain?

There are many reasons to go to the pool or the sea. To cool off, to exercise or to relax, and the list goes on and on.

But one of the best reasons to take a dip, according to Seena Mathew, PhD, a neurobiologist and assistant professor of biology at the University of Mary Hardin-Baylor, is that swimming is the right exercise for brain health and longevity.

It's no secret that aerobic exercise can help prevent some of the damage of aging. But a growing number of studies show that swimming can offer a unique boost to brain health. Regular swimming has been shown to improve memory, cognitive function, immune response, and mood. Swimming can also help repair damage from stress and create new neural connections in the brain.

For starters, swimming, like almost all other types of aerobic exercise, releases endorphins in your brain—hormones that make you feel good. “This helps you feel better, so swimming tends to improve your mood and make you feel less sad or anxious ,” says Dr. Matthew.

However, what sets swimming apart from cardio workouts like running and spinning is that it has been more closely linked to increasing brain chemicals related to memory and cognition, making it a great way to optimize brain health.

The expert explains that research has shown that physical exercise releases a growth factor and a peptide in the brain called brain-derived neurotrophic factor, known as BDNF.

“It’s been found that when you have memory impairment and cognitive difficulties, you have lower levels of BDNF, and what’s been observed is that swimming helps increase those levels ,” he says. “This helps with memory and cognition, so over time, your memory improves or isn’t affected as much by the passage of time.” Beyond the memory and mood aspects of swimming, there’s also the fact that swimming engages your whole body.

Improves cognitive ability

"Aerobic exercise increases the creation of new cells and creates new pathways in our brains. This helps us store new information and recall it whenever needed ," notes the biologist.

A 2019 study conducted with 18 adult swimmers found that 20 minutes of swimming at a moderate pace helped boost brain function, which is an indication that swimming for brain health can be extremely positive — something we can begin to verify with more research, as well as personal testing.
