Why the Water? The Science of Why We Swim

For most of us, a swimming pool is a symbol of summer vacation or a quick way to cool off in July. But if you look at the biology and physics of the water, the pool is actually one of the most powerful tools we have for health, safety, and even brain development.
As we count down to our May 2026 opening at The Flex in Joliet, we want to share exactly why the water is a game changer for every member of your family, from toddlers to grandparents.
The Toddler Years: Safety and Milestones
For parents of young children, swimming is often viewed through the lens of safety. While that is the priority, the benefits go much deeper into how a child’s brain actually grows.
- The Safety Factor: Research shows that formal, high-quality swim lessons can reduce the risk of drowning by 88% in children ages 1 to 4. It is the single most important investment you can make in your child’s safety.
- Cognitive Boost: A major four year study found that children who start swimming early reach developmental milestones significantly faster than their peers. This includes things like counting, language expression, and fine motor skills.
The Teen Years: A Mental and Physical Reset
Teenagers are under more pressure than ever. Between school and competitive field sports, their bodies and minds need a break that actually helps them perform better.
- Active Recovery: For the baseball or soccer player, the pool is the ultimate “reset button.” Because the water supports 90% of their body weight, they can build core strength and stay conditioned without the impact of the turf.
- The “Blue Mind” Effect: Scientists have identified a state called “Blue Mind.” It is a meditative state our brains enter when we are in or near water. For a teen, the pool is a rare place where the phone is away and the world goes quiet, naturally lowering stress and anxiety.
The Adult Years: Maximum Efficiency
If you are an adult in Orland Park or Joliet, your time is a luxury. You need a workout that works as hard as you do.
- The 800x Rule: Water is roughly 800 times denser than air. Every movement you make in the pool is a form of resistance training. You are building muscle and burning between 500 and 700 calories an hour without ever feeling the “clunky” weight of a gym floor.
- Heart Health: Regular swimming has been shown to reduce arterial stiffness and lower blood pressure. It is essentially “cardio without the crash.”
The Senior Years: Independence and Mobility
As we age, the goal is to keep moving. The water provides the only environment where you can build strength without the fear of a fall or joint pain.
- Fall Prevention: Studies have shown that seniors who swim are 33% less likely to suffer a fall compared to those who do other types of exercise. The water builds the deep stabilizer muscles in the legs and core that keep you upright on land.
- Joint Relief: In our signature 90°F (32°C) water, chronic pain and arthritis often fade into the background, allowing for a range of motion that simply isn’t possible on dry land.
The Poolside Pulse: Swimming by the Numbers
- 90%: The amount of your body weight supported by the water.
- 88%: The reduction in drowning risk for toddlers who take formal lessons.
- 800x: How much denser water is than air (making every move a workout).
- 33%: How much more stable a senior becomes after regular time in the pool.
