As Teitelbaum previously explained to mbg, a common reason people can wake up in the middle of the night is an adrenaline rush caused by low blood sugar. When your blood sugar is low, it can cause an increase in the stress hormone cortisol, which obviously doesn’t set you up for a good night’s sleep.

He adds that everyday stressors can also cause your blood sugar to drop, making you hungry and cranky (and this is especially common right before bed, making it even more difficult to snooze).

Luckily, Teitelbaum has some tips for dealing with stress before bed—and in the form of a midnight snack, no less.
