Did you know your diet may be affecting how well you sleep at night? What you eat—and when you eat—can have a major impact on your ability to fall asleep, stay asleep, and wake up refreshed.
At Comprehensive Sleep Medicine Associates (CSMA), we believe good sleep starts with good habits—and nutrition is one of the most important.
How Diet and Sleep Are Connected
Your body relies on a delicate balance of nutrients and hormones to support healthy sleep. Healthy sleep means getting the right amount and quality of sleep to feel rested and energized during the day. It involves a good sleep schedule, a relaxing pre-sleep routine, a conducive bedroom environment, and a healthy diet.
Certain foods and eating patterns can promote relaxation and help your brain produce melatonin (your sleep hormone), while others can sabotage your rest.
What healthy and unhealthy choices can you easily make to improve your sleep? Let’s break it down:
Foods That Promote Better Sleep
Tryptophan-rich foods (like turkey, eggs, and dairy) help your body produce serotonin and melatonin.
Complex carbohydrates (whole grains, oats, brown rice) stabilize blood sugar and boost serotonin.
Magnesium-rich foods (nuts, seeds, spinach, avocado) relax muscles and nerves.
Herbal teas (chamomile, valerian root) can promote calm and drowsiness.
Foods That Can Disrupt Sleep
Caffeine (coffee, chocolate, some teas) is a stimulant that can stay in your system for hours.
Alcohol might help you fall asleep, but it disrupts REM sleep later in the night.
Spicy or fatty foods can trigger indigestion and disrupt sleep quality.
Heavy meals before bed can keep your digestive system working overtime when it should be winding down.
The Role of Meal Timing
When you eat can be just as important as what you eat. Avoid large meals at least 2–3 hours before bed to prevent discomfort and sleep disturbances. If you’re hungry close to bedtime, choose a small, sleep-friendly snack like a banana with almond butter or whole grain toast with honey.
Tips for Using Nutrition to Improve Sleep
Stay Hydrated—but Not Too Late. Dehydration can lead to nighttime cramps or headaches, but drinking too much close to bedtime can cause sleep disruptions due to bathroom trips.
Balance Blood Sugar Levels. Stable blood sugar prevents nighttime wakeups. Avoid sugary snacks and eat balanced meals with protein, healthy fats, and fiber.
Watch Your Caffeine Intake. Cut off caffeine by mid-afternoon to avoid lingering effects at bedtime.
Create a Consistent Eating Pattern. Irregular eating can confuse your metabolism and circadian rhythm. Eat meals at roughly the same times each day.
Fuel Better Sleep with Better Nutrition
If you’ve been struggling with insomnia or feeling tired despite getting "enough" sleep, your diet could be playing a bigger role than you think. At CSMA, we help patients take a whole-body approach to sleep health—including lifestyle and nutritional guidance.
