Poor sleep isn’t just feeling tired. Your food choices and daily habits may be silently disrupting your sleep hormones and your health.
Getting 7–9 hours of quality sleep isn’t a luxury; it’s essential for your metabolism, hormones, brain, immune system, and longevity.
If you struggle to sleep deeply or wake refreshed, this guide will show you: What to eat, when to eat it, and the daily habits that support restorative sleep, all backed by science.
Why Sleep is Non-Negotiable
Poor sleep isn’t just about feeling tired. Your food choices and daily habits may be silently disrupting your sleep quality, circadian rhythm and overall health.
Here’s why 7–9 hours is non-negotiable:
- Metabolism: less sleep increases ghrelin → more hunger & cravings
- Mood & Anxiety: amygdala becomes hyper-reactive → stress & irritability
- Hormones: cortisol rises, insulin sensitivity drops
- Immune Health: inadequate sleep can affect immune function and our natural defences
- Ageing & Longevity: chronic short sleep is associated with poorer cognitive and long-term health outcomes
Foods for Better Sleep
1. Tryptophan-Rich Foods
Tryptophan is an amino acid your body uses to make serotonin, which can then be converted into melatonin — the hormone that helps regulate our sleep-wake cycle.
- Turkey
- Chicken
- Eggs
- Nuts & seeds
- Fermented dairy (kefir, yoghurt)
Tip: Pair with whole-food carbohydrates like sweet potato or fruit, which may help tryptophan reach the brain.
2. Melatonin-Rich Foods
Melatonin helps regulate your circadian rhythm:
- Tart cherries / tart cherry juice
- Walnuts
- Pistachios
- Eggs
3. Mineral-Rich Foods for Relaxation
Magnesium and potassium support healthy muscle and nervous system function, helping the body relax and wind down:
- Bananas
- Avocado
- Spinach
- Sweet potato
- Figs
4. Omega-3 Fatty Acids (Fatty Fish)
Omega-3 fatty acids support brain health and healthy sleep regulation:
Salmon, trout, mackerel, sardines

5. Evening Herbal Teas
Gentle herbal teas can be a calming addition to your evening wind-down routine:
- Chamomile → contains apigenin, a plant compound studied for its calming properties
- Passionflower → traditionally used to support relaxation and sleep
- Lemon balm → traditionally used to support calm and relaxation

Habits That Support Sleep
Sleep isn’t just about what you eat, your daily habits matter too!
Morning Habits:
- Wake at the same time each day (with a flexibility of 30 min either side of sleep and wake times)
- Get morning sunlight exposure (no sunglasses)
- Move your body (early in the day)
- Eat meals at consistent times
Evening Habits:
- Set a consistent bedtime
- Dim lights 1 hour before bed (lamps rather than overhead lights)
- Reduce emotional stimulation (news, arguments, intense social media)
- Avoid large meals close to bedtime — eating a heavy meal too close to bed can interfere with comfortable, restful sleep (aim for 2+ hours before bed).
- Keep naps short — around 20–25 minutes. Longer or late-afternoon naps can leave you feeling groggy and may make it harder to fall asleep at night.
If you often feel wired, tired or constantly “on”, read my guide on how to regulate your nervous system for more simple ways to bring calm into your day.
What to Avoid for Better Sleep
- High-sugar & ultra-processed foods → can contribute to blood sugar fluctuations and poorer diet quality
- Highly processed takeaways → often high in refined carbohydrates, added fats and salt, and can leave you feeling heavy before bed
- Caffeine after midday → particularly if you’re sensitive to caffeine or struggling with sleep
- Large late meals
Putting It All Together
Combine sleep-supporting foods with supportive habits for more restorative sleep. Sleep deeply, wake refreshed, and give your body the time it needs to rest, repair and regulate. Quality sleep is one of the foundations of better energy, mood, metabolism and overall health.
