What should you have as a bedtime snack? You should eat something that boosts your levels of melatonin. It’s a neurotransmitter responsible for sleep. You need that chemical to kick in before bed or you’ll be staring at the ceiling all night. So here are the foods that will increase your melatonin the most:

Sunflower seeds
Tart cherries

All of these foods have other health benefits, and you may want to start snacking on these particular foods whether it's bed time or not.

So try this – eat a half-cup of blackberries 30 minutes before bed. UCLA researchers found that after 3 nights of that, you’ll be sleeping more soundly.
