Slow-Wave Sleep
Slow-Wave Sleep
The deepest stage of sleep, during which the body repairs itself and strengthens immune function.
Details
Slow-wave sleep (Stage N3) is the deepest stage of sleep, characterized by dominant slow delta waves. It is a critical time for physical recovery, tissue repair, immune function enhancement, and growth hormone secretion.
As we age, the amount of slow-wave sleep tends to decrease. Regular exercise (completed at least 4 hours before bedtime) can help increase slow-wave sleep.
Getting enough slow-wave sleep is essential for physical and mental vitality the next day. Mindy is here to support you in building habits that protect your deep sleep.
