Sleep
Understanding sleep, its disorders, and how to improve the quality of rest
Sleep ( light, deep and REM sleep), each playing a specific role in physical and mental recovery.
Quality sleep depends on both:
- the duration of sleep
- its continuity
- the proper distribution of cycles during the night
These mechanisms are closely influenced by the circadian rhythm, hormones (including melatonin), stress, and digestion .
Why is sleep so important?
Insufficient or non-restorative sleep can affect:
- energy and vigilance
- memory and concentration
- stress and emotion management
- immunity
- digestion and metabolism
Sleep therefore plays a central role in the overall balance of the body.
