How Does Food Impact Your Sleep?

What You Eat Might Be the Missing Piece of Better Sleep

You can have the perfect pillow, a cool dark room, and a sensible bedtime - and still lie there wide awake. The piece most of us overlook is the food and drink we choose through the day. What you eat, and when you eat it, talks directly to the chemistry that runs your sleep.

Your body actually builds sleep from what you feed it: nutrients like tryptophan become serotonin, and serotonin becomes melatonin - the hormone that tells your brain it's night. Some everyday foods hand your body those raw materials, and the research is striking. Adults who ate two kiwifruit before bed slept about 13% longer, tart cherries naturally boost melatonin, and each step closer to a Mediterranean-style diet comes with better odds of good sleep.

Just as importantly, a few common choices quietly work against you. Caffeine fades by only half every five hours - so a coffee taken a full six hours before bed can still cut more than an hour from your sleep. Heavy, spicy, or sugary meals late at night, a sneaky chocolate nightcap, and a big glass of anything right before bed all fragment the rest you're after.

The good news? Small, simple tweaks make a real difference. Discover the six foods your sleep will thank you for, the ones worth rethinking, an interactive tool that shows how much caffeine is still in your system at bedtime, and the easy 3-2-1 wind-down rule for a smoother landing into sleep.
