I have seen studies that for each hour under 8 that you sleep, the body releases 12% less testosterone...can't recall where it was, but I was stunned to be reading it...MSR9889 wrote:never thought about it from a cortisol stand point, but that would make sense given how my body has been developing. only have significant fat left on my stomach and inner thighs, less horny than in the past, etc. and i certainly cant build muscle which is miserable.matter2003 wrote:

good night sleep=lower amounts of cortisol, the stress hormone and anti-anabolic...when you don't sleep well, your body interprets it as a stress and releases large amounts of cortisol, which will negatively impact any muscle building you might want to do. It also releases less testosterone, so it in effect becomes a double whammy.
Since cortisol cancels out testosterone, releasing more cortisol and less testosterone is like an anabolic nightmare....
When you think about it, we really are controlled by hormones. Insulin, Leptin, Ghrelin, Cortisol, Testosterone, Estrogen, etc...
Positively manipulating your hormonal profile, is as important or even more important to muscle growth than anything you do at the gym, eat or drink in the form of shakes, etc...
The "anabolic ratio" is what determines muscle building capabilities of your body. This is the ratio of Testosterone to Cortisol. If it is not tilted in testosterone's favor, you will build little or no muscle, even if doing the exact same workout, eating the exact same foods at the exact same times, etc as someone whose ratio is positive...
BTW, meditation can reduce cortisol levels by up to 50%, I have been doing it for about 3 weeks now and have noticed some of the benefits already...also, the list of things that the body interprets as stress and increases its cortisol levels in response to are sometimes pretty off the beaten path...ie, not drinking water while doing cardio or working out WILL increase cortisol levels significantly when you finish...
