Good quality sleep allows muscles to recover between workouts and supports the production of energy you need to exercise. Shortly after you enter non-rem sleep (slow wave sleep), the pituitary gland releases growth hormones that support muscle growth. Not getting enough sleep can lead to reduced muscle strength during physical activities.

Collagen synthesis happens during non-rem sleep (slow wave sleep) where growth hormones are released triggering the creation of collagen. Good quality sleep is associated with improved skin barrier function, reduced signs of aging, and promotes beautiful skin tone and a healthy glow.

Good quality sleep regulates key hormones that control weight loss. The hormone leptin creates the feeling of fullness - controlling appetite. With poor sleep, these levels are decreased – increasing appetite and the likelihood of over eating. A lack of sleep also increases cortisol, a fat storing enzyme.

Getting consistent and adequate REM sleep reduces the levels of cortisol and other stress hormones. After a sound night’s sleep, well rested people remain calm and are less reactive to negative situations.
