Sleep and why it's such an important aspect of our lives seems to be a really hot topic at the moment and rightly so. Did you see BBC One's 'How to stay young'? Well worth seeing on catch up if you can. One of the topics covered showed how getting too little sleep can disrupt our hormone levels. Ghrelin and Leptin are normally released on and off to regulate normal feelings of hunger but they don't work properly if you're sleep deprived leading to cravings for high calorie sugary food.
Sound familiar? I know that if I get less than 7 hours sleep after a big night out or when I'm worried about something, I really 'need' a chocolate fix the next day!
There's a new book out that I'm keen to read which should explain more. In 'Why we sleep: The new science of sleep', top sleep scientist Matthew Walker argues that sleep is more important for our health than diet or exercise. He explores twenty years of cutting-edge research to solve the mystery of why sleep matters, delving into everything from REM sleep to how caffeine and alcohol affect sleep and why our sleep patterns change across a lifetime.
Sounds well worth a read before you nod off for hopefully your 7 to 8 hours!
