The easiest (and least expensive) rule to follow is to hydrate. Joy McCarthy, author of Joyous Detox, holistic nutritionist and Genuine Health Ambassador recommends drinking at least a litre of H20 overnight. “Keep it beside your bed, and if you wake up thirsty, take a couple sips. And whatever you don’t drink overnight, drink first thing in the morning before you get out of bed.” But it’s not just regular ol’ water that’ll make a difference in your skin and your sleep. McCarthy also suggests a nightly herbal detox tea. Look for ingredients like milk thistle, dandelion greens, and burdock root.
