Floating in water. There isn't much better, is there?
Relaxation is an important part of well-rounded health. Practicing relaxation techniques in a pool of warm water can help to loosen tight muscles and ease joint pain, whether from aging, chronic illness or injury. It may also help to reduce your blood pressure, reduce your heart rate and reduce the amount of stress hormone your body produces while boosting your energy and your immune system.
Look for classes that teach water-based relaxation techniques -- or practice at home -- such as progressive muscle relaxation, yoga or mindful meditation to help you achieve both physical and mental balance.
