False.
The endocrine system does not "rest" during sleep — it remains active and many hormones follow circadian and sleep-stage–dependent patterns. Examples:
- Growth hormone is released in large pulses during deep (slow-wave) sleep.
- Melatonin secretion from the pineal gland rises during darkness to promote sleep.
- Cortisol follows a circadian rhythm, dropping after sleep onset and rising toward morning.
- Insulin, thyroid, and reproductive hormone secretion also vary across sleep/wake cycles.
So sleep changes the timing and amounts of hormone release, but the endocrine system continues regulating physiology rather than resting.
