Meditation, in its simplest form, is the practice of observing your breath. It can reshape behavior, change brain composition and permanently boost your ability to regulate emotions. Studies have also shown meditation reduces inflammation in the brain, thus lowering your risk for cancer and other diseases. Additionally, it sets you up to feel awe, relieves pain and protects the brain from aging. Meditation can help with anxiety, depression, insomnia and fatigue. It’s no wonder the humble practice has grown into a billion-dollar industry.
