Best Sleep Tips:
I. Life-Changing Health Benefits Of Quality Sleep
1. Boosts Productivity, Focus, & Problem-solving.
Quality sleep improves motivation, productivity, and problem-solving skills, reducing the time required to complete tasks. Additionally, it enhances creativity, integrating new information with existing knowledge, cross-referencing and finding associations between the two to solve problems your brain could not solve before sleep.
2. Supports Healthy Eating, Blood Sugar Regulation, & Weight Loss.
Sleep plays a key role in regulating the hunger & fullness hormones ghrelin & leptin, helping to manage cravings and support healthy eating habits. Also, it stabilizes blood sugar by improving insulin sensitivity, helping to prevent glucose spikes and supporting overall metabolic health.
3. Optimizes Exercise Performance & Outcomes.
Studies show an underslept body resists giving up energy-dense fat, causing significant weight loss from muscle mass. In addition, proper sleep boosts physical performance by supporting circulation, respiratory function, & the body’s cooling ability.
4. Reduces Stress & Inflammation.
Sleeping well keeps the sympathetic nervous system balanced, reducing cortisol, stress, and inflammation. By managing these factors, quality sleep protects against chronic stress-related health issues. In a one-week study, poor sleep was shown to alter the activity of 711 genes, increasing the expression of those linked to chronic inflammation while reducing the expression of genes that help regulate immune function and inflammation control.
5. Enhances Mental, Emotional, & Relational Health.
REM sleep processes emotional memories in the absence of a stress-related chemical called noradrenaline, reducing reactivity by up to 60% and improving mental clarity. Along with that, it recalibrates the brain regions essential for accurately deciphering emotional cues boosting empathy, emotional stability, and social awareness, which are key to building positive relationships.
6. Strengthens Heart & Immune Health.
Restorative rest lowers blood pressure and reduces strain on the heart, significantly decreasing cardiovascular issues and the risk of heart attack by up to 200% in adults over 45. Not only that, it also strengthens immunity, boosting T cell activity up to 70%, enhancing the body’s defenses against illness.
7. Improves Gut & Brain Health.
Healthy sleep supports a balanced gut microbiome by lowering cortisol levels, which enhances digestion and gut health. Deep sleep activates the glymphatic system in the brain, which clears toxins with cerebrospinal fluid, promoting optimal cognitive function and protecting against neurodegenerative diseases like Alzheimer’s.
8. Promotes Hormonal Health.
Chronic sleep loss can deplete testosterone levels in men, adding up to a decade to their biological age. Effective rest maintains balanced levels of reproductive hormones, supporting menstrual cycles and testosterone levels. This hormonal stability is essential for wellness factors like fertility, muscle mass, libido, and bone density.
9. Elevates Learning, Memory, & Motor Skill Mastery.
Optimal sleep transfers new information from short-term memory in the hippocampus to long-term memory in the neocortex, allowing for effective learning and freeing up space for further knowledge acquisition. Also, it strengthens motor skills by transferring learned abilities into subconscious brain circuits, making them easier to execute.
II. Major Inhibitors Blocking You From Healing Rest
1. Excessive Caffeine Consumption.
Research has found many negative impacts from caffeine-infused sleep, including reducing deep non-REM sleep, impairing the glymphatic system, and increasing the risk of cognitive disorders like Alzheimer’s. Additionally, a lack of deep non-REM sleep leads to detrimental effects on the cardiovascular and immune systems.
2. Sleeping On Alcohol Or THC.
Alcohol and THC induce a sedated state rather than promoting healthy, restorative rest by disrupting the brain’s natural sleep cycles. Both substances reduce REM sleep, which has been linked to a shorter lifespan. Additionally, studies show that alcohol can impair memory retention by 30-50% after learning.
3. Warm Sleep Environment.
Even a small rise in body temperature by 1-3 degrees can increase nighttime awakenings and reduce sleep depth and quality.
4. Bright Light Exposure After Dark.
Darkness triggers the pineal gland to release melatonin, a hormone that signals it’s time to sleep. However, bright light—especially blue light—disrupts both the production and release of melatonin, making it difficult to initiate restorative rest.
5. Sleeping At The Wrong Time For Your Chronotype.
Different chronotypes require different sleep patterns for optimal rest. For example, teenagers and evening types have naturally delayed sleep-wake cycles, making early wake times challenging and less conducive to productivity and cognitive function. Chronotype misalignment can reduce sleep quality, impair health, and increase the risk of immune dysfunction. Shift work, an extreme misalignment due to our diurnal nature, is classified by the WHO as a probable carcinogen.
6. Consuming High-Sugar Foods.
Sugar increases the body’s metabolic rate and, as a result, raises body temperature. Therefore, consuming sugary foods—especially before bed—can increase nighttime awakenings, reducing sleep depth and quality.
7. Relying On Sleeping Pills.
Sleeping pills induce sedation instead of restorative rest by inhibiting the electrical brain activity needed to generate healthy sleep stages. Prolonged use has been linked to increased risks of mortality and cancer, as well as rebound insomnia. Additionally, they can cause a 50% reduction in brain cell connections, deteriorating learning and memory ability.
8. Relying On Melatonin Supplements.
While melatonin supplements are commonly used studies show they offer only minimal benefits, increasing sleep duration by an average of just 3.9 minutes and efficiency by 2.2%. High doses may suppress natural melatonin production, and due to the lack of regulation in the U.S., melatonin supplements often contain inaccurate doses, with studies showing up to 80% less or 460% more than what is stated on the label. Plus, melatonin can also impact hormone levels, potentially influencing puberty, though it may be beneficial for older adults as natural production declines with age.
9. Under-Sleeping.
Consistently sleeping less than 8 hours, or not meeting your individual sleep needs, can have serious consequences. Just one night of insufficient sleep increases toxic proteins in the brain, reduces immune activity by 70%, and affects cognitive function. Even losing one hour of sleep during daylight savings causes a 24% rise in heart attacks, along with more car accidents, suicides, and harsher judicial sentences. Everyone’s sleep needs vary by age, health, stress, activity, and gender. For instance, teenagers may need more due to shifted circadian rhythms, while women often require extra rest because of hormonal fluctuations and increased brain activity. When sleep duration doesn’t align with your unique needs, it limits deep, restorative rest, impacting overall health.

III. Science-Backed Solutions to Sleep Well
1. View sunrise & sunset.
Light exposure during sunrise and sunset is the most powerful signal for setting your internal clock. Light-sensitive receptors in your eyes, called melanopsin retinal ganglion cells, detect unique light wavelengths at these times that help your brain recognize the time of day and establish a healthy sleep-wake or circadian rhythm.
- Avoid painful light exposure, as this can damage your retina. There’s no need to look directly at the sun, simply facing its direction allows photons to reach your eye receptors.
- If viewing sunrise or sunset isn’t possible, get outdoor light exposure as close to these times as possible.

2. Replace bright & blue light with dim, red light in the evening.
Darkness triggers melatonin secretion, promoting healthy sleep onset. As it gets darker your eyes become more sensitive to light, so even small amounts at night can suppress melatonin making it harder to fall asleep. Bright lights, blue-spectrum lights (like LEDs), and overhead lights (due to increased receptor sensitivity to light from above) are especially disruptive. However, light sources such as candlelight and very dim red lights will not disrupt melatonin.
- Wear a hat or sunglasses at night when in brightly lit areas. 😎
- Use blue light-blocking glasses at night. Red-tinted lenses are more effective at blocking blue light than non-tinted options.
- Adjust device screens to red using your device’s color filter settings and reduce brightness if you need to use them after dark.
- Use candlelight, red bulbs, and dim lights low in the visual field, such as outlet plug-in lamps, as light sources at night.
3. Keep a cold sleep environment.
To fall asleep, your body temperature must drop by 2-3 degrees Fahrenheit. Maintaining a cool temperature throughout the night helps you stay asleep and prevents waking. If body temperature rises during the night, it can disrupt sleep, leading to lighter sleep and frequent awakenings.
- Keep your bedroom cold, studies show around 67 degrees Fahrenheit is generally ideal.
- Wear breathable sleepwear.
- Use breathable bedding such as bamboo sheets & muslin cotton blankets in layers that can be easily removed as needed.
- Try cooling devices such as a cooling fan or a cooling mattress pad.
4. Consume caffeine early in the day.
Caffeine has a half-life of 5-6 hours, meaning half the caffeine you consume can still be in your system 6 hours later which blocks adenosine, a compound in our brain that makes us feel tired. Consuming caffeine early in the day and reducing the strength allows the body enough time to clear it out, letting adenosine do its job to promote sleepiness. Even if caffeine doesn’t seem to affect your ability to fall asleep, it can still harm sleep quality.
- Switch to non-caffeinated beverages 10-12 hours before your desired bedtime.
- Try caffeine-free alternatives like Teccinos, chai blends, or Dandy Blend.
- Opt for lower-caffeine drinks such as matcha, cacao, chai lattes, London fog, low-caffeine coffee, decaf coffee, green tea, or black tea.
5. Resolve any sleep disruptions & respiratory disturbances.
Breathing issues, bathroom trips, or cortisol spikes can interfere with restorative rest. Resolving these issues helps ensure uninterrupted deep sleep & waking feeling refreshed.
- Find a craniofacial dental sleep medicine practitioner to evaluate your airways and check for sleep breathing issues with a sleep study (at-home options are available). Conditions like sleep apnea can disrupt your sleep quality even if you’re unaware. Treatments like Vivos may help.
- Support healthy nasal breathing by cleaning your space with an air purifier & Hepa mattress vacuum and using tools such as mouth tape, breathe right strips, microbiome-friendly nasal spray, and eucalyptus chest rub.
- Use a sleep tracker like an ultrahuman ring, Oura ring, whoop, or other smart device to pinpoint disruptions. This data can help us uncover unconscious issues inhibiting deep sleep and motivate us to maintain healthy sleep habits.
- Try to limit fluid intake to 5oz or less after the first 10 hours of the day or a couple of hours before bedtime. To learn all about optimal hydration check out this post.
- Eat a small bedtime snack to stabilize blood sugar and prevent cortisol spikes that can wake you in a stressed state during the night. Choose options that combine glucose and protein, like a banana with nut butter, chia seed pudding, Greek yogurt with berries, or an apple with cheese.
6. Enhance your core temperature shifts to energize & promote sleepiness.
Your core temperature rhythm, a key part of your circadian system, naturally rises during the day boosting energy by stimulating metabolism and the nervous system, then falls at night promoting sleepiness by slowing metabolism and calming the nervous system. We can leverage these natural temperature shifts with activities that further cool or raise body temperature to enhance this energy boost or sleepiness effect.
- Promote an early rise in core temperature: Engage in heart rate-elevating exercise or eat a meal in the morning to stimulate metabolism. Both actions raise core temperature and set an ideal rhythm for energy during the day and restful sleep at night.
- Increase energy with cold exposure: Use short cold showers, ice water face dips, or cold plunges. Your core temperature compensates by heating up after the cold exposure, which energizes you.
- Encourage a core temperature drop before bed: Take a hot bath or shower, use a low-EMF heating pad, or enjoy a sauna session. Heat exposure brings blood to the skin’s surface, which cools the core and promotes sleepiness.
Note: Avoid prolonged cold exposure as it can lower core temperature too much and stress the body. Use caution and consult a healthcare professional when trying new protocols.
7. Try alternatives for alcohol, THC, & sleeping pills.
Data reveals that alcohol, THC, and sleeping pills can negatively impact sleep quality and overall health. Thankfully, there are plenty of healthier alternatives that promote relaxation and mood enhancement without disrupting sleep efficiency. In place of alcohol and THC, explore mood-boosting mocktails, tinctures, and herbal smoke blends. For sleep challenges, science backed supplements and sleep-promoting foods can provide safer, effective solutions. Always consult your healthcare practioner and research potential side effects (examine.com) before trying new compounds.
- Experiment with botanical concentrates such as this euphoria elixir, the social elixir, or mood juice & make mocktails with your favorite mixers.
- Try pre-made mocktails like kin euphorics (check caffeine content). My favorites include the spritz, bloom, and lightwave drinks.
- Switch to healthier herbal smoking blends like this relaxing botanical smoking blend.
- Explore mood-enhancing alternatives from brands like Kin Euphorics, Three Spirit, Apothekary, Little Saints, Ghia, and Anima Mundi.
- Supplement with bioavailable forms of magnesium like threonate or glycinate until you find one that works best for you. Liquid forms work best for me, and I get good results with this magnesium glycinate.
- Drink tart cherry juice; studies show it can increase sleep time by 60-90 minutes and reduce time awake in bed.
- Make a sleepy girl mocktail using tart cherry juice, magnesium powder, and sparkling water.
- Eat kiwis with the skin to improve sleep quality & duration. One study found that eating two kiwis before bed reduced the time to fall asleep by 35%.
8. Implement therapeutic tools to release mental & emotional blocks to sleep.
Therapeutic tools & systems can help us process emotions, reduce overthinking, and calm anxiety that prevents a good night’s rest. By engaging in cathartic activities, we can relieve stress, activate the parasympathetic nervous system, lower cortisol, & acquire healthy habits that promote relaxation and an easy transition into restorative rest.
- Write down your thoughts and worries before bed to clear your mind. One study found this practice can cut the time it takes to fall asleep by 50%.
- Try Emotional Freedom Techniques (EFT) or “tapping” using methods like the 9 EFT tapping points or natural bio-destressing. Findings demonstrate how EFT can be highly effective on stress with 86% of PTSD participants resolving their diagnosis after just six sessions.
- Practice sleep-inducing breathwork such as the 4-7-8 method (in for 4 seconds, hold for 7 seconds, out for 8 seconds) or the 4-6 method (in for 4 seconds, out for 6 seconds) to activate relaxation.
- Listen to guided meditations like yoga nidra (yogic sleep) or sleep hypnosis to quiet the mind.
- Explore somatic therapies like EMDR or HBLU to address challenges around sleep from trauma.
- Establish a wind-down routine with cues like calming music or sounds, candlelight, a hot bath, or comfy pajamas to signal your brain and body that it’s time to decompress.
- Consider Cognitive Behavioral Therapy for Insomnia (CBT-I) to address sleep-disrupting habits. Visit sleepfoundation.org for resources.
9. Align with your chronotype.
Your chronotype reflects your genetically ingrained sleep pattern, ranging from early bird to night owl. Understanding your most natural sleep-wake rhythm will help you identify your optimal sleep window. When we can align with this window, we can improve sleep quality and boost daytime productivity.
- Take an online quiz to discover your chronotype.
- Adjust your sleep and wake times to better match your chronotype.
