Swimming is the healthiest sport. Experts explain why

Swimming has long been called the most complete sport, and a growing number of studies confirm that it’s not only enjoyable but also a real investment in health. Water relieves pressure on joints, allows for safe muscle strengthening, improves heart and lung performance, and also soothes the mind and reduces stress. Experts emphasize that regular swimming sessions can extend life and improve its quality. Is it worth jumping into the water even if your technique isn’t perfect? The answer turns out to be surprisingly simple.

Why is swimming considered the healthiest sport?

Swimming stands out among physical activities because it engages the whole body while relieving joint stress. Movement in the water requires effort from the arms, legs, core, and back, while putting no strain on the spine or knees – making it a safe option for seniors or those recovering from injury. Experts point out that the benefits affect not only body shape but also heart and lung health.

Swimming is a dynamic, rhythmic activity that raises heart rate and effectively lowers blood pressure – explains Prof. Hirofumi Tanaka from the University of Texas. Meanwhile, Korean researchers from Busan have shown that for middle-aged women, just three months of swimming, three times a week, leads to significant improvements in blood lipid profiles – specifically, reduced levels of total cholesterol and triglycerides, and an increase in beneficial HDL cholesterol.

Swimming and the musculoskeletal system

Swimming activates nearly all major muscle groups – from the arms and back, through the core, down to the legs. Water provides natural resistance, turning each movement into both a strengthening and stretching exercise. Importantly, this resistance is evenly distributed, and the body moves in an environment that relieves joint pressure.

To stay afloat and move forward, you need to use many large muscles at once – notes Dr. Heather Massey from the University of Portsmouth. Such full-body activation promotes balance and prevents overloads typical of unilateral sports like running or tennis. Thanks to the feeling of lightness in water, swimming is one of the most commonly recommended forms of rehabilitation after injuries and orthopedic surgeries, as well as a suggested activity for people working desk jobs. It supports muscle strength recovery, improves range of motion, and speeds up regeneration.

The impact of swimming on mental health and well-being

Rhythmic breathing and repetitive movements in water have a calming effect, and the aquatic environment itself helps soothe the nervous system. Researchers emphasize that swimming reduces stress levels, improves sleep quality, and helps combat symptoms of depression and anxiety. Swimming reduces emotional tension and acts like a natural form of meditation – says Dr. John Whyte, an American preventive medicine specialist. Additionally, simply being in the water brings a sense of lightness and detachment from everyday problems, offering the mind a break from information overload. During swimming, the body produces more endorphins, serotonin, and dopamine – the hormones responsible for good mood, motivation, and improved memory.

Does swimming beat other sports?

Every type of physical activity has its benefits, but swimming stands out by combining many advantages in a single discipline. Unlike running, which can heavily strain the joints, movement in water is much gentler on the body while still engaging the entire musculature. Water acts as a natural shock absorber, which means that even people with excess weight or chronic orthopedic issues can exercise without fear of injury.

In a weight-relieving environment like water, the risk of injury is much lower compared to high-impact workouts – emphasizes Dr. Mitch Lomax, an exercise physiology specialist at the University of Portsmouth.

But the benefits don’t stop there. Swimming burns calories at a rate similar to intense running, while strengthening and sculpting muscles as effectively as gym workouts. According to studies published in the British Journal of Sports Medicine, fans of freestyle or breaststroke have up to a 28% lower risk of premature death compared to those who avoid water-based activity.

If there’s a sport that combines movement, recovery, and longevity – swimming certainly deserves the title.
