“This is how your sleep shapes up during an acute depression episode:

Prolonged sleep latency, reduced total sleep time, reduced sleep efficiency (characterized by intrusions of wakefulness), reduced three and four (deep) sleep, reduced REM latency, and increased REM density. Also – increased body temperature, increased ACTH, cortisol, and cerebral metabolism (in non REM sleep), as well as decreased growth hormone TSH, prolactin, testosterone, and possibly melatonin.

I do not profess to understand exactly what all that means, but if my mechanic ever handed over a clipboard with something like that on it I would know it was time to get rid of my car.”

Excellent advice.
