When it comes to your brain, a lack of sleep is tantamount to smoking a bong! It ignites brain receptors called endocannabinoids – as in cannabis. And those receptors give us the munchies! So a lack of sleep makes you more vulnerable to cravings for sugary, high-fat foods – and makes eating them more pleasurable than normal. So make sure you get a good night’s sleep if you don’t want to pig out like a pot-head.
