When you exercise, your body releases chemicals called endorphins. These endorphins interact with your brain and trigger a positive feeling in the body.
That euphoric feeling after you take a brisk walk in the morning is often accompanied by a positive and energizing outlook on life. Endorphins are one of the best natural chemicals to diminish the perception of pain while producing positive mental stimulation.
Manufactured in your brain, spinal cord, and throughout your body, endorphins are released in response to neurotransmitters. Endorphins interact with these neurotransmitters similar to morphine, acting like a "sedative" to calm and relax.

Try to exercise at least 20 to 30 minutes, three times a week. Studies indicate that exercising four or five times a week is even better. Take it easy if you are just beginning. Start exercising for 20 minutes. Then you can build up to 30 minutes.
