Probably the most commonly known characteristic that can help through food is tryptophan — yes, that sleepiness from the Thanksgiving turkey is no joke. Tryptophan is an amino acid that can help the brain get into a relaxed state, similar to serotonin and melatonin. You can obtain tryptophan and serotonin from carbohydrates, particularly 100 percent whole grain oats, brown rice, corn or quinoa.
Give yourself some dedicated wind-down time. It doesn’t have to be a full hour or an elaborate routine, but try to spend at least 20 to 30 minutes doing something that relaxes you before you try to fall asleep. That could be taking a warm bath or shower, changing into comfy pajamas and sipping a cup of chamomile tea. Or something completely different — so long as it’s relaxing to you.
