Sleeping better makes it easier to stick to your diet and eat healthily. Research has shown that if you sleep well, it's easier to resist junk food and snacks, giving you another good reason to get a decent night's rest.
Scientists at the University of California, Berkeley, discovered that if you're sleep-deprived, your brain gets more excited when it sees high-calorie food. At the same time, the more tired you are, the more likely you are to give in to temptation.
But sleep well, and suddenly those unhealthy snacks don't look anywhere near as appealing. Yet another example of why good sleep equals good health.
