It inhibits growth at all concentrations, but to different extents.Only in chronically high quantities does it inhibit growth.
True.These are not good and evil hormones, this is a circadian rhythm of the ebocrune system. These systems work on negative feed back loops and so without one you cannot have the other.
Acute stress increases thyroid hormones but I don't think it's via cortisol.Yes cortisol inhibits thyroid function, but in a healthy state an acute secretion of cortisol via acute stress is exactly what illicit the secretion of respirative hormones which then make adaptation to a more robust status quo possible.
Immediate increase of thyroid hormone release during acute stress in rats: effect of biogenic amines rather than that of TSH? - PubMed - NCBI
"It is suggested that the acute release of thyroid hormone might be due to the effect of biogenic amines which may be blocked by some alpha-adrenergic blocking agents."
No. Coffee increases cAMP and intracellular calcium, which promotes the synthesis of NO. There is obviously more interactions that his, but hypoxia -> cortisol -> DHT -> eNOS is definitely not the primary mechanism. I cannot find a study that supports that.Coffee itself does not improve bloodflow, it impedes it. This causes tissues to become hypoxic, then release cortisol to continue cellular respiration under stress (releasing ffa), which then once cleared will cause an upsurge of dht, which the. Will raise n.o. Synthase, which then produces nitric oxide, which the. Improves blood flow. It's all a negative feedback loop.
