Can Anything Help With Sleep
Drink some warm milk before bedtime
Decades ago, scientists looked into this folk remedy and posited that tryptophan, an amino acid in milk (and turkey), might be responsible for its supposed sleep-inducing effects. Earlier research had shown that when tryptophan is released into the brain, it produces serotonin—a serenity-boosting neurotransmitter. But when milk (and other tryptophan-rich foods) were tested, they failed to affect sleep patterns. “Tryptophan-containing foods don’t produce the hypnotic effects pure tryptophan does, because other amino acids in those foods compete to get into the brain,” explains Art Spielman, M.D., an insomnia expert and professor of psychology at the City University of New York. Warm milk at bedtime may be comforting, but it won’t boost sleep-promoting serotonin.
Have a bedtime snack.
A light bedtime snack can stave off hunger, a known sleep robber. But eating high-glycemic-index (GI) carbohydrates—hours earlier at dinner—might also help. (High-GI foods cause a greater rise in blood sugar and insulin than do lower-GI foods.) A recent paper in the American Journal of Clinical Nutrition found that when healthy sleepers ate carbohydrate-rich suppers of veggies and tomato sauce over rice, they fell asleep significantly faster at bedtime if the meal included high-GI jasmine rice rather than lower-GI long-grain rice. While the authors aren’t sure how it happened, they speculated that the greater amounts of insulin triggered by the high-GI meals increased the ratio of tryptophan relative to other amino acids in the blood, allowing proportionately more to get into the brain.
