Cloud Nine Collagen Sleep Tea - herbal loose leaf 35g Pack (approx. 30 serves) Did you know the term "beauty sleep" has merit, as a good night's sleep can mean better skin health because when you sleep, levels of the stress hormone cortisol drop during sleep time, which helps skin repair daytime damage. and then the body can also make more collagen, which minimizes fine lines, recovers elasticity and more human growth hormone is released increasing muscle mass and strengthening skin and improving texture. So, when you're sleep-deprived, your body naturally makes more of the stress hormone cortisol, and elevated levels of cortisol can lead to increased stress and inflammation in the body and in turn hurting your skin's quality. When you sleep, your body also boosts blood flow to the skin, which means you wake to a healthy glow. So, the lesson here? Skimp on sleep and your complexion could look drab, ashen, or lifeless.
