Swimming is great exercise and works the major muscle groups with very little stress on your joints and can correct nagging misalignment's in your body's musculoskeletal system, easing chronic pain. The cooling effect from the water and the weight of the water can sooth joint inflammation in just one swim.
Floating on your back for 20 minutes can lower your stress hormone cortisol and as a result, you will sleep more deeply that night. Floating is comforting and relaxing and worth giving it a try. Float your cares away!
