Improve Sleep with Exercise and Diet: A Science-Backed Guide

If you’ve ever tossed and turned at night, you’re not alone. Millions of people struggle to get quality sleep. Fortunately, you can improve sleep with exercise and diet—two powerful, proven tools that work together to reset your sleep cycle naturally.

Let’s break down how to get started.

How Exercise Helps Improve Sleep Naturally

Fall Asleep Faster Through Physical Activity

Exercise raises your core body temperature, which later drops and signals to your brain that it’s time to rest. This cooling process helps your body wind down more efficiently.

Boost Deep Sleep with Regular Aerobic Exercise

Incorporating moderate aerobic activity, such as brisk walking, swimming, or cycling, has been shown to improve the quality of slow-wave sleep—the most restorative phase of your sleep cycle.

Lower Stress Hormones for Better Rest

Beyond physical benefits, exercise also reduces stress hormones like cortisol and adrenaline. As a result, your nervous system becomes more relaxed, which prepares you for deeper, uninterrupted rest.

Best Time to Exercise for Quality Sleep

• Best: Morning or early afternoon

• Okay: Evening, if it’s light to moderate

• Avoid: Intense exercise 1–2 hours before bed

How Diet Affects Sleep Quality and Duration

1. Complex Carbohydrates

Foods rich in complex carbs support the production of serotonin and melatonin, which are essential for sleep regulation.

Top choices include:

• Brown rice, oats, quinoa
• Sweet potatoes
• Whole grain bread or pasta

2. Lean Proteins

Tryptophan, an amino acid found in protein-rich foods, helps your body create serotonin and melatonin.

Sleep-friendly protein options:

• Turkey, chicken
• Tofu, eggs
• Greek yogurt

3. Sleep-Friendly Snacks

Having a small, balanced snack 1–2 hours before bed can ease you into sleep without disrupting digestion.

Smart late-night bites:

• Banana with almond butter
• Oatmeal with milk
• Whole grain toast with turkey

To make logging your food easy, just text your meals to TomatoSMS. It automatically tracks your macros, calories, and highlights ingredients—like caffeine or sugar—that could affect your sleep.

What to Avoid to Sleep Better at Night

Steering clear of common disruptors can make a big difference in your sleep quality:

• Caffeine (after 2 PM): It can linger in your system for 6–8 hours and delay sleep.
• Alcohol: Although it may make you drowsy at first, it disrupts deep sleep and causes frequent wake-ups.
• Heavy Meals: Large or spicy meals close to bedtime often lead to indigestion and discomfort.
