So Im big into running, clears the head, boost self esteem, yada yada,
so anyway, on average when im emotionally stable, i can run a fairly good run, and if i have the right song playing, i can get a slight runners high type feeling i would call it, but when i have something on my mind, like anxiety, it fuels me soo much more, like it feels like a drug, I get an almost intense cold chill feeling all through my body, and I feel like i could run forever, but the thing is, i almost only get this feeling when im like... really really depressed or worried... and i like it. alot, so much it almost makes me want to feel shitty all the time... anyone know whats going on?
Thats pretty cool bro thats the SAME EXACT way I am. When I went running one day a few months back in wds, I got the same anxiety high to push myself untill I fainted in the summer heat from dehydration.
The thing is people are mixing up 2 chemicals here, endorphins AND adrenaline.
That cold feeling you get through your body should accompany a tingling sensation in your head, thats adrenaline, not endorphins.
The reason you get it cause anxiety will stimulate your adrenal glands to release adrenaline when your body is in "flight mode". Imagine it like you're running, then you see someone pointing a gun at you (anxiety; which you are simulating through mere anxious thought when running - not by an actual gun) adrenaline surges to the point of making you high... which is precisely whats happening with you when you run.
That anxiety trips a nice release of adrenaline, not endorphins. Endorphins play different roles, like the mood increase and what not. But its always more adrenaline because if endorphins could actually trump adrenaline, you wouldn't really be in an anxious state to begin (you tend to notice the endorphins more when you actually stop running, adrenaline goes down, and your body relaxes/mood elevates). This is natures way of "coming down" from violence basically in the wild... thousands of years ago.
Hope this helps!
edit: one more thing, a lot of people hold the misconception that when you get shot somehow endorphins are what kills the pain, thats really bullshit imo. Endorphins DO play a major role in moderating pain, but adrenaline itself is a MAJOR pain killer. The fact is, when you get traumatically injured, both adrenaline AND endorphins surge, but I still personally believe the majority of the pain killing is from adrenaline, not endorphins affecting opiate receptors.
I realize how opiates kill pain, but a lot of people don't realize how speed kills pain either, and in my own experience, when on speed my skin literally feels numb, I can burn it with a cigarette and not feel anything.. opiates don't do that, they seem to numb specific regions of the body (more joints, muscles, etc), while adrenaline works on other areas. I'm not 100% sure, but I'm prob going to go read about it now cause I just confused myself lol..
