there are many possibilities of causes in my experience. from bad sleep habits. to caffeine intake sugar. which all effect cortisol levels. excessive exercise. is it 24/7? how is your sleep? or is it more random bursts? i'm just someone who has been to the psychiatrist about my "generalized anxiety disorder" so many possible natural supplements as well that have great user reviews. magnesium rhodiola rosea meditation l-theanine omega 3s. minus the meditation and rhodiola (which really does have great reviews for anxiety but doesn't work for me). could it be that your diet is deficient in any of those? deficient in sleep? night shift?
it feels like my heart is racing but my pulse rate is normal and i feel out of breath. what could this be? . i do suffer from anxiety. i have taken natural supplements that promote relaxation and that usually helps with my anxiety. recently my heart has been acting this way and i've tried taking the supplements thinking its part of my anxiety but nothing changes.
