Healthier Tomorrows’ functional nutrition philosophy is rooted in our Five-Tier Approach, with sleep as the foundation. Sleep isn’t just something that happens at night; it’s something you prepare for all day, and there are many small, intentional choices that can dramatically improve both sleep quality and duration.
Use this checklist to identify what’s already working and where your sleep may need more support.
How to Calm Your Nervous System for Better Sleep
Sleep begins when your body feels safe.
- Maintain a relaxing evening routine to give your body the message of winding down
- Take slow, deep breaths to activate your parasympathetic (“rest & digest”) nervous system, before bed and throughout the day
- Massage your hands or feet before bed
- Minimize electronic use and stimulation after dinner
- Remember: how you end the day sets the tone for the next one
The Best Bedtime Routine for Better Sleep
Consistency matters more than perfection.
- Mimic the light outside, inside your home – dim the lights (or swap to lamps versus overhead lighting) once the sun sets, or at least two hours before bed
- Avoid electronics at least 60 minutes before bed
- Use blue light–blocking glasses (those with orange lenses are most effective)
- Read a physical book or listen to an audiobook/podcast instead of scrolling
- Keep electronics out of the bedroom
- Make sleep something you look forward to, not a battle
How to Create the Best Sleep Environment
Your bedroom should cue your body to rest.
- Cool room temperature
- Dark space (blackout curtains, sleep mask, cover any light in your bedroom (however small))
- Comfortable mattress and bedding
- Cut off fluid consumption earlier in the evening if nighttime urination disrupts sleep
Understanding Sleep Cycles: Deep Sleep, REM & Why They Matter
Not all sleep is created equal.
- Prioritize deep sleep to support physical repair and regeneration
- Protect REM sleep for memory consolidation and emotional regulation
- Aim for consistent bed and wake times—even on weekends
- Although sleep tracking devices can provide benefits for gathering data, if they are an added stressor, reevaluate
How to Increase Melatonin Naturally (Without Supplements)
Melatonin is built—not forced.
- Begin winding down before bed, not at bedtime
- Eat fiber-rich carbohydrates alongside protein, fat, and veggies at dinner (fiber-rich carbs provide a source of tryptophan that supports serotonin, which plays a role in melatonin production)
- Darkness stimulates melatonin—avoid electronics and stimulation at least 60 minutes before bed
- Use melatonin supplements with caution, especially in children—focus on diet and lifestyle first
Foods and Eating Habits That Help You Sleep Better
Nourishment and rest are meant to work together.
- Balance meals and snacks to support better blood sugar control
- Aim to stop eating 2-3 hours before bedtime
- Notice how late, spicy, and heavy meals affect your sleep quality
- Be mindful of caffeine timing and total intake—ideal to avoid caffeine after 2 pm
- Make note of how alcohol impacts your sleep—make adjustments as needed
Sleep Differences for Women and Men: Menstrual Cycle, Melatonin & Cortisol
Sleep Differences in Women
- Expect changes in deep, REM, and light sleep across the menstrual cycle
- Anticipate more sleep interruptions leading up to menstruation, especially with PMS
- Consider tracking your sleep alongside your cycle for 2-3 months to recognize your patterns
- Wind down earlier—melatonin often peaks around9 pmm
- Aim to fuel your body within 30 minutes of waking to help blunt the morning cortisol spike—protein coffee, handful of nuts, hard-boiled egg, etc.
Sleep Differences in Men
- Melatonin typically peaks later (10–11 pm)
- Avoid excessive stimulation late at night
- Eating immediately upon waking is less necessary for cortisol regulation
Common Sleep Disruptors: Caffeine, Screen Time & Late-Night Habits
- Small habits add up.
- Limit late-day caffeine and sugar
- Minimize evening stressors when possible
- Avoid “one last task” that stimulates your mind
- Avoid checking your phone before bed or reaching for your phone if you wake in the night
When to See a Functional Dietitian About Your Sleep
Quality sleep isn’t about hacks; it’s about alignment and getting back to basics. It does not need to be overcomplicated. When nervous system regulation, hormones, light exposure, nutrition, and routine work together, sleep becomes deeper, more restorative, and more consistent.
If your sleep is an ongoing challenge despite “doing everything right,” our functional dietitians can provide guidance on taking a deeper look at your nervous system balance, blood sugar regulation, gut health, and/or hormone patterns.
Having an ongoing conversation with your body is one of the most powerful health tools available. Changes in and difficulties with sleep are a message from the body. Learning to translate the message and giving your body what it wants and needs can take time, but the results are powerful.
