Repeated lack of sleep can actually raise the stress hormone cortisol, which brings on a pre-diabetic state. Inadequate sleep also lowers your levels of leptin, the hormone that works to decrease your appetite.
As leptin production is blocked, your brain receives familiar signals telling you to eat. You feel hungry and crave sweets and starches. Too bad your body doesn’t actually need food – what it needs is a nap!
But cravings are hard to ignore. And once you give in to them, your insulin levels soar and then quickly crash. This amounts to mood swings, stress, sadness, impatience, aggravation, and ultimately, another food binge.
Why do this to your body? Forgo the confusion by getting plenty of sleep – 7-8 hours – every night.
