SLEEP
Quality sleep starts the moment you wake up. Built through small, intentional habits.
If you’ve been struggling with poor sleep or sluggish recovery, the good news is that science offers clear solutions. From adjusting your light exposure to managing stress and timing your workouts, small tweaks can make a big difference. Here are 15 evidence-based ways to improve your sleep quality and recovery in 2025.
1. Get More Natural Light During the Day
Getting exposure to natural sunlight or bright indoor light during the day helps keep your circadian rhythm in sync. When your body’s internal clock functions properly, you’re more likely to have steady energy throughout the day and better-quality sleep at night.
A 2022 study found that bright light exposure during the daytime can improve both how well and how long people sleep. Because of this, it’s generally recommended to get daily sunlight whenever possible—or use a bright light lamp or bulbs if you spend most of your time indoors.
Similarly, a 2017 study of over 100 office workers observed that individuals who received more morning light fell asleep faster and enjoyed better sleep overall, especially during the winter. This effect was linked to a more balanced and well-aligned circadian rhythm.
What to do: Spend 15–30 minutes outside each morning. If natural sunlight isn’t available, consider a bright-light therapy lamp to simulate daylight exposure.
2. Limit Blue Light in the Evening
Exposure to artificial light after sunset can interfere with the body’s natural production of melatonin which is one of the key hormones that signals to the brain it’s time to relax and prepare for sleep.
A 2023 systematic review published in Chronobiology International found that exposure to blue-wavelength light—the type emitted from phone screens, computers, and LED lighting—can delay your circadian rhythm and reduce time spent in deep, restorative sleep. Similarly, researchers from the Harvard Medical School Division of Sleep Medicine report that even short periods of screen exposure before bed can significantly suppress melatonin production, the hormone that signals your body it’s time to sleep.
Recent research also examined the use of blue-light filtering glasses as a potential solution. A 2023 review of randomized controlled trials found limited but emerging evidence that these glasses may help improve sleep quality by reducing nighttime blue-light exposure.
To limit nighttime blue light exposure, try wearing blue-blocking glasses, dimming bright lights, and switching off screens like TVs and smartphones about two hours before going to bed.
3. Avoid Caffeine Late in the Day
Caffeine can be a helpful boost for alertness, focus, and athletic performance. But new research shows that when consumed too late in the day, it may interfere with quality sleep. A research review published in 2023 found that evening or late-day caffeine intake reduced total sleep time by about 45 minutes and lowered sleep efficiency by approximately 7 %.
The reason may be that caffeine disrupts important phases of sleep (including deep sleep) by blocking adenosine and altering nervous system activity, though the exact effects of daytime caffeine on sleep remain somewhat inconclusive.
What you can do:
Avoid caffeinated drinks at least 8 hours before your bedtime.
If you’re using caffeine supplements (pre-workouts, energy shots), consider avoiding use 13 hours or more before bed.
If you really want a late afternoon drink, opt for decaffeinated coffee or herbal alternatives instead.
4. Keep Naps Short and Early
Taking brief naps during the day can be refreshing, but long or poorly timed naps may interfere with your ability to fall asleep at night.
When you sleep for extended periods during the day or do so at irregular times, you risk confusing your body’s internal clock — also known as your circadian rhythm — which may make it harder to fall asleep at your usual bedtime.
That said, the impact of daytime napping varies depending on the individual. Researchers turn to systematic reviews of available studies to gain broader insight.“Napping may be beneficial for a range of outcomes that benefit athletes,” including physical and cognitive performance, researchers concluded in a 2021 review of 37 studies on the topic, published in the journal Nature and Science of Sleep. But they cautioned that most of the studies were found to be of only moderate quality.
What to do: If you nap, aim for early afternoon (1–3 p.m.) and keep it under 30 minutes.
5. Keep a Consistent Sleep Schedule
Going to bed and waking at the same time helps your body’s circadian rhythm stay aligned. A consensus statement of the National Sleep Foundations recent analyses highlight that sleep regularity (low day-to-day variability) is linked with better sleep and health outcomes.
What to do: Keep bedtime and wake-up within a 30-minute window daily, even on weekends.
6. Consider Melatonin Supplementation
Melatonin is a key hormone that signals your brain it’s time to wind down and head to bed. Studies show that taking melatonin may help people fall asleep faster.
Unlike prescription sleep medications, melatonin in the United States is sold as a dietary supplement, not a drug. This means it isn’t regulated by the Food and Drug Administration (FDA) for consistency in quality or dosage. In Canada, melatonin is classified as a Natural Health Product and is regulated by Health Canada under the Natural Health Products Regulations, though standards can still vary between brands.
Research studies have explored melatonin doses ranging from 0.1 to 10 milligrams, typically taken within two hours before bedtime, depending on individual needs and sensitivity.
If you’re considering melatonin, it’s best to start with a low dose and adjust gradually based on how your body responds. Before adding it to your routine, consult a qualified healthcare professional, especially if you take other medications or have underlying health conditions. For children and adolescents, always seek medical guidance before use — the long-term safety of melatonin in younger individuals has not been well studied, and dosage needs can vary significantly. Choosing products that carry third-party testing seals (such as USP Verified or NPN-approved in Canada) can help ensure purity and accurate labeling.
What to do: Start small, monitor for a week, and increase only if needed (and discuss with a clinician if using longer-term or for children).
7. Consider these other supplements
Several natural supplements may help promote relaxation and support better sleep.
These include:
While none of these are quick fixes for sleep problems, they may be beneficial when used alongside healthy sleep habits. Try introducing one supplement at a time to see how your body responds and to avoid unwanted side effects.
8. Avoid Alcohol Before Bed
Having a few drinks in the evening might seem relaxing, but alcohol can interfere with both sleep quality and hormone balance.
Recent, 2024 Research shows that alcohol can worsen snoring and sleep apnea symptoms and disrupt normal sleep cycles. It also affects melatonin production, a hormone that helps regulate your body’s internal clock.
An occasional drink with dinner or during social events isn’t usually a concern, but it’s best to avoid alcohol within a few hours of bedtime to support deeper, more restorative sleep.
What to do: Avoid drinking within three hours of bedtime and stay hydrated with water instead.
9. Upgrade Your Mattress and Bedding
What you sleep on matters. Low-quality bedding or an unsupportive mattress can contribute to things like lower back pain, which in turn can make restful sleep harder to achieve.
Your sleep surface affects spinal alignment and sleep quality. Recent clinical and review work support medium-firm as a common “best” starting point; bedding fibres influence thermoregulation (e.g., wool/cotton regulate moisture/temperature; linen may feel cooler in warmth).
Beyond mattress firmness, a 2024 systematic review looked at nine studies comparing bedding and sleepwear materials (cotton, polyester, wool, duck down, goose down, linen, blends) and found meaningful differences in sleep quality depending on fabric and ambient temperature.
For example, wool bedding helped adults fall asleep more easily in cooler rooms, while linen sheets improved sleep for younger adults in warmer conditions.
What to do: If you haven’t updated your mattress or bedding in several years, doing so could be a relatively simple way to improve your sleep, although it can be an investment, and the “best” choice is highly individual.
10. Optimize Your Sleep Environment
Your sleep environment involves a lot more than just a comfortable mattress and sheets. Factors like room temperature, noise levels, ventilation, and even the levels of carbon dioxide (CO₂) or airborne particulates can affect how well you sleep. A 2023 study found that higher bedroom temperature, elevated CO₂, and increased noise were each independently linked to lower sleep efficiency.
Tips Improve Your Sleep Environment:
Minimize external noise and stray light (including device lights or alarm-clocks glowing) in your bedroom.
Blackout curtains, eye masks or smart sleep masks are recommended to create a dark environment to improve sleep quality and reduce disruptions.
Keep your room at a comfortable temperature, around 65°F (18 °C) is a good starting point, though personal preference and climate may vary.
Improve your air quality by ensuring good ventilation (so CO₂ levels and stale air don’t build up) and reducing allergens or pollutants in the space.
11. Avoid Eating Too Late
Eating heavy meals close to bedtime can interfere with how well you sleep. Research shows that late-night eating may reduce sleep quality and make it harder for your body to transition into deep, restorative rest.
Rule of Thumb: It’s generally best to finish dinner at least two to three hours before going to bed. If you’re hungry later, stick to a light snack instead of a full meal.
The type of food you eat late at night also matters. Studies suggest that high-carbohydrate meals eaten right before bed can negatively affect sleep quality compared with lower-carb or higher-protein options.
12. Reduce Fluid Intake Before Bed
Large evening fluid intake can cause nocturia and fragment sleep. Population and clinical reviews show nocturia is common and increases with age, contributing to reduced sleep quality and next-day fatigue.
What to do: Taper fluids 1–2 hours pre-bed and use the bathroom right before sleep.
13. Relax and clear your mind in the evening
Relaxation techniques lower arousal and prepare the brain for sleep. Systematic reviews and meta-analyses support mindfulness/meditation and music for improving subjective sleep quality and reducing sleep latency in many adults.
What to do: Try slow nasal breathing (4 seconds in, 6 seconds out), a 10-minute guided meditation, or calming music before lights-out.
14. Identify Possible Sleep Disorders
If good habits aren’t enough, conditions like sleep apnea, restless legs, or chronic insomnia may be present. Recent global estimates suggest substantial OSA burden and ~12–16% adult prevalence for insomnia (criteria vary).
What to do:
Consult a healthcare provider or sleep clinic if you snore loudly, wake up gasping, or feel tired despite long sleep duration.
A non-invasive magnetic nasal dilator like AirMag Pro
can help improve airflow during sleep to reduce snoring and promote deeper, restful sleep.
15. Exercise Regularly –– But Not Too Late
Regular physical activity improves sleep, a large meta-analysis found exercise improves sleep efficiency and reduces sleep onset latency. Evening exercise generally does not harm sleep, but high-intensity sessions finishing within ~1 hour of bedtime can modestly delay onset or reduce REM in some people. Aim to finish hard sessions ≥2–3 hours before bed.
What to do: Aim for 150 minutes of moderate exercise per week and finish workouts at least three hours before bedtime.
Frequently Asked Questions
What is the 10-3-2-1-0 rule for sleep?
The 10-3-2-1-0 rule is a simple framework designed to help you wind down before bed.
It suggests:
10 hours before bedtime = stop consuming caffeine.
3 hours before = avoid heavy meals and alcohol.
2 hours before = finish any work or mentally demanding activities.
1 hour before = turn off screens and bright lights.
0 = the number of times you should hit snooze in the morning.
Following this routine helps your body and mind transition more smoothly into rest mode and can make it easier to fall asleep consistently.
How can I get better at falling asleep?
Building a consistent sleep routine is one of the best ways to train your body to fall asleep faster. Try going to bed and waking up at the same time each day, even on weekends. Create a calm environment by reducing light and noise, keeping your bedroom cool, and avoiding stimulating activities close to bedtime. Limiting caffeine, alcohol, and large meals in the hours leading up to sleep can also make a big difference.
Bottom Line
Sleep is the cornerstone of recovery and performance. Just as nutrition fuels the body, quality sleep fuels the mind, focus, and longevity. Apply these evidence-based strategies consistently to build a routine that supports both elite performance and everyday well-being.
