Why is cortisol essential despite its risks?

Cortisol is actually vital to life, even though chronically elevated levels may carry some dangers. For example, it regulates your blood pressure, managing sodium retention. It deals with glucose, so your brain is fed constantly. It helps manage inflammation, so you don't get too carried away with the reactive responses. Additionally, it regulates your circadian rhythm, aligning everything with the day-night cycle.

The function of circadian coordination comes next. Cortisol spikes around 8 AM, waking you up, and your systems feel energized. It drops through to hypnone, growing dimmer and stops being secreted. These rhythms synchronize your sleeping hours, wakefulness, and control your body temperature. If it goes awry, you'll quickly find that your metabolism and cognition are disintegrating, as this function is crucial.

Only harm comes with the rein for the sustained elevation ride above 25 μg/dL. At a proper level, cortisol protects; chronic elevation makes you sick; receptors become throttled; it's the cycle of downregulation; the metabolism and immune system function malfunction, defining HPA dysfunction. It's the threshold theory from above that determines why temporarily elevating the emoji is okay and could even be beneficial, compared to the full-on pathological yoke.

So then the absence of cortisol can be life-threatening.1 complete cortisol absence is immediately dangerous. Adrenal insufficiency causes dangerous hypotension, hypoglycaemia, and threatens cardiac arrest - all treacherous conditions showing just how important cortisol really is to basic survival. It's the overproduction of cortisol, possibly chronically elevated above your natural set points for extended periods, that becomes a problem.
