Hi when we exercise at gym there is the stress just goes away and you feel amazing . is there science to it or it just a mental thing ? thanks

Both: Exercise releases endorphins which stimulate the pleasure centers on the brain. The social aspects of going to a gym are also helpful. Keep up with the exercise. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.

Both. : In the physical sense, exercise results in the release of endorphins which make you feel good. And in the emotional sense, one feels a sense of accomplishment for achieving something useful and healthful for one’s self.

Science : Check this link, in addition to many ither studies, keep it up, wish you well http://www.mayoclinic.org/diseases-conditions/depression/in-depth/depression-and-exercise/art-20046495?pg=1

Embrace it: Nobody really understands it. In skydiving, the fear -- and every other negative emotion you may have in your life -- vanishes the instant you exit the door. Psychologists have written about this as something to tap to treat mental illness. I'm very glad you have this -- and it showcases the principle that managing our emotional health is first and foremost about what we make ourselves DO.
