How Nutrition Influences Sleep

The food we consume impacts our sleep in various ways:

1. Hormone Regulation: Certain foods influence the production of sleep-regulating hormones like melatonin and serotonin
2. Blood Sugar Levels: Stable blood sugar promotes better sleep, while fluctuations can disrupt it
3. Digestive Comfort: Heavy or spicy meals close to bedtime can cause discomfort and disrupt sleep
4. Hydration: Proper hydration is essential for good sleep, but excessive fluid intake before bed can lead to nighttime awakenings
5. Stimulant Intake: Caffeine and alcohol can significantly impact sleep quality and duration

The Science of Nutrition and Sleep

Research has consistently shown the profound impact of diet on sleep:

• A study published in the Journal of Clinical Sleep Medicine found that low fiber and high saturated fat and sugar intake was associated with lighter, less restorative sleep[^1].
• Another study in Advances in Nutrition revealed that a Mediterranean-style diet rich in fruits, vegetables, whole grains, and lean proteins was associated with better sleep quality[^2].

Pro Tip: Keep a food and sleep diary for at least two weeks. Note what you eat and drink, and how you sleep each night. This can help you identify patterns and make informed dietary changes for better sleep.
