This has been a long running problem for me ever since I was young. Many exercises, especially running has always been a little challenging for me. Regardless of my fitness, the act of exercise alone had caused me to feel extremely stressed out and anxious. Running often puts me in a rather depressive mood.
From what I am aware, exercise usually helps to reduce stress and anxiety as opposed to causing it. It releases endomorphin which should help out the mind. Yet I dont think I have ever felt a change in mood for the better by exercising. My nutritionist seems at a loss in helping me out with this long running problem.
I am wondering if there is any scientific basis for the idea that exercise can actually cause stress and anxiety?
