It’s 3 p. m. on a Tuesday and you’d do anything for a donut … with chocolate fill … and those rainbow sprinkles on top. Are you hungry? Bored? You may only have a suit of the “sleep munchies.” According to a recent study published in the journal SLEEP, a lack of zzz’s stokes your appetite just like marijuana might. Seriously! When you don’t get enough shut-eye, your brain illuminations up with the same chemicals that cause stoners to giggle over Funyuns and chomp on Twinkies.
