Meditators attend to conditions that affect their practice, and sleep is one of the most impactful. You can skip to the tips listed below, but understanding the biological mechanisms can help inform your practice.

Each cell in our bodies contains a built in timer, or series of clock genes (PER, BMAL, CLOCK, etc) that regulate cell function. These processes are entrained, or fixed, to light cycles. Each cell has its own circadian rhythm. There are subsidiary clocks in other brain regions and peripheral clocks throughout the body. A number of processes throughout the entire gastrointestinal tract and liver, for example, appear to be under circadian control- such as nutrient uptake, processing, and detoxification (Reinke, 2016). The intestinal microbiome is regulated by circadian rhythms, which can significantly impact immune function and metabolism (Voigt et al, 2016). The heart, too, has its own rhythms which affect output, workload, and energy supply-to-demand ratios (Young, 2006). The brain's ability to clear Amyloid-Beta 42, a protein closely linked to Alzheimer's disease, is tied to the circadian cycle (Clark et al, 2022)

When our rhythms are entrained, or fixed to diurnal cycles of night and day, our cells function optimally. When they are disrupted, our hormonal schedules become dysregulated, our mood suffers, our health is compromised. We increase the risk of cancer, obesity, heart disease, anxiety-disorders and depression, Type II diabetes, and the kind of neurodegeneration typical of dementia and Alzheimer's disease. Sleep–circadian disturbances are the rule, rather than the exception, across every category of psychiatric disorder.

Mood and attention are dependent on sleep. Dopamine is a neurotransmitter that influences learning, attention, and motivation. Acetylcholine is a neurotransmitter that amplifies activity of brain circuits associated with focus and attention. Norepinephrine is a neurotransmitter that amplifies activity of brain circuits associated with alertness. After a good night's sleep, it's as if stores of these neurotransmitters were replenished. We wake up feeling alert and motivated. By contrast, when we do not sleep well night after night, we wake up with brain fog and begin to feel unmotivated. Over time, this dampens our mood causing chemical imbalances. Anxiety, depression and lack of sleep are strongly correlated.

No drug is as beneficial as sleep is for health. Neither therapy nor pharmaceuticals will avail us much if our sleep is consistently compromised and our habits and sleep patterns are not addressed or corrected. We can start by examining our habits- especially sleep, diet, and exercise. If they're not on point, begin there with intention.

A good night's sleep helps with memory and learning. Sleep restores the brain’s computational power. Neuroplasticity, which refers to the brain's capacity to form and reorganize synaptic connections, especially in response to learning or experience, occurs during sleep. Knowledge and memory are consolidated after a good night's sleep. The brain regions also synchronize to create motor memory. Sleep is like the Save function in an application, but sleep is also essential before learning. It primes the brain to absorb new information. There's a 40% decrement in memory consolidation without sleep.

A good night's sleep is usually divided into 4 stages: NREM stage 1, NREM stage 2, NREM stage 3, and REM. The stages follow a specific order. Each has a unique function and role in maintaining overall brain health. Stage 1 [NREM (Non-Rapid Eye movement)]. Stage 1 is the transition between wakefulness and sleep. During stage 1 sleep:

  • Brain activity slows

  • Heartbeat, eye movements, and breathing decrease

  • The body relaxes; muscles may twitch

This brief period of sleep lasts about five to 10 minutes. Interestingly, sleep is not a global state. Neuronal populations in different parts of the brain "sleep" before others. As we fall asleep, the thalamus cycles down before the frontal cortex. The thalamus serves as a switchboard or relay station for motor and sensory information. Sensory information still enters the sense doors- the ears still process sound waves, mechanoreceptors still process touch, the nose still detects odors, but, when the thalamus unplugs, the raw data doesn't get interpreted.

We spend approximately 50% of our total sleep time in NREM stage 2, or light sleep, which lasts for about 20 minutes per cycle.

During stage 2 sleep:

  • We become less aware of our surroundings

  • Body temperature drops

  • Eye movements stop

  • Breathing and heart rate become more regular

In stage 2, the brain produces bursts of rapid, rhythmic brain wave activity called sleep spindles. Slow waves and sleep spindles can originate from axons within the hippocampus's cornu ammonis 3 region (Wang et al., 2024). Sleep spindles are thought to be a feature of memory consolidation—when your brain gathers, processes, transfers, and filters new memories you acquired the previous day (Andrillon et al., 2011). The hippocampus, associated with memory formation, plays a crucial role in generating slow waves and sleep spindles which, in turn, affect memory processing.

In NREM stage 3, the slowest brain waves known as delta waves (1.5-4 Hz) peak. Neurons in the thalamus appear to regulate sleep and wakefulness. This stage is referred to as delta sleep, a period of deep sleep where any noises or activity in the environment fail to register or wake the sleeping person.

During NREM stage 3 sleep:

  • Muscles are completely relaxed

  • Blood pressure drops

  • Breathing slows

  • The body starts its physical repairs.

  • Toxic proteins cleared

  • The brain consolidates declarative memories— general knowledge, facts or statistics, personal experiences, and other things learned that day (Feld, Diekelmamnn, 2015).

In REM (Rapid Eye Movement) stage 4, the brain is aroused with mental activity, but voluntary muscles become immobilized which prevents us from acting out our dreams.

REM sleep begins approximately 90 minutes after falling asleep. In stage 4:

  • The brain lights up with activity

  • The body is relaxed and immobilized

  • Breathing is faster and irregular

  • Eyes move rapidly

  • We dream

  • Memories are consolidated.

  • Emotions and emotional memories are processed and stored (Glosemeyer, 2020).

When we are alert and awake, signals travel from the dendrites, or arms, of the cells to the soma, or body, of the cell. At the soma, a spike is generated and a signal runs down the axon and on to other cells. During REM sleep, however, dendrites in the prefrontal cortex show increased activity, but the soma shows decreased activity. This decoupling suggests that the neurons are processing information received, but not sending them on. This is consolidation and allows the brain to respond to environmental cues the following day (Aime et al., 2022).

We cycle through these 4 stages several times during the hours we sleep: from light to deep (usually in the first half of the night), then from light to REM during the second half of the night. The brain also wakes up neurologically more than 100 times a night, sometimes called microawakenings. Waves of noradrenaline trigger short awakenings (usually not detectable to the conscious mind). "Short-term awakenings are a natural part of sleep phases related to memory," asserts Celia Kjarby, lead author of a study published in Nature. These waves are important for the consolidation of learning and memory (Kjaerby, 2022).

Stress-induced awakenings, however, disturb natural sleep. New research reveals that neurons in the preoptic hypothalamus—the region of the brain that regulates sleep and body temperature—are rhythmically activated during non-rapid eye movement sleep (NREM). Glutamatergic neurons (VGLUT2) are rhythmically activated during NREM sleep. Stress activates these brain cells out of turn, causing "microarousals," that interrupt sleep cycles and decrease the duration of sleep episodes.

A small molecule called microRNA-137 helps regulate a protein in brain cells called hypocretin (Holm et al., 2022). Hypocretin plays a role in the order of the sleep stages. Researchers suspect that hypocretin plays a role in both insomnia, the inability to fall asleep, and narcolepsy, the ability to stay awake. Insomniacs have too much hypocretin the brain; narcoleptics have too little.

Sleep restores balance between order and chaos. During sleep, the glymphatic system clears out toxins and metabolic waste from the brain. It takes 7 to 8 hours for the glymphatic system to flush out metabolic waste. Neurons coordinate electrical signals that generate rhythmic waves which work like pumps and help to wash cerebrospinal fluid through the brain, cleaning it up along the way (Jiang-Xie et al., 2024).

The glymphatic system is like an irrigation system. In conjunction with lymphatic vessels within the brain, noxious toxins are drained into thin tubes-which allows for the circulation and removal of brain waste fluid. That fluid exits the brain and drains into channels in the outer tissue layer that surrounds it (Mehta et al., 2022).

Heart health affects sleep and sleep affects heart health. Pulsations of the cerebral arteries help to drive the clearance of toxic brain byproducts in the perivascular spaces with each heartbeat. However, high blood pressure over the long term stiffens arteries, impairing function and the ability to clear toxins. This disruption of blood flow and brain fluid underlies many neurodevelopmental disorders.

Lifestyle choices such as sleep position, alcohol & caffeine intake, exercise, omega-3 consumption, nutrition, meditation, intermittent fasting and chronic stress also modulate glymphatic clearance for better or for worse.

Side sleeping improves glymphatic clearance compared to either supine (on the back) or prone (front-lying) positions. Alcohol impairs sleep. Ingesting caffeine late in the day (for most people) affects the quality and quantity of sleep. Pharmacologically, caffeine is an adenosine-receptor antagonist (Nehlig, 2004). Adenosine is a hormone that regulates sleep and sleep induction (Huang, 2011). Caffeine blunts adenosine, which explains why it is harder for most people to fall asleep after ingesting caffeine.

Morning exercise is ideal. Vigorous exercise prior to bed is not. Late night exercise elevates heart rate and body temperature. A falling body temperature is best for sleep.

Many hormones that regulate hunger and appetite are replenished after a good night's sleep. Sleep upregulates the satiety hormone, leptin, and downregulates the appetite-stimulating hormone, ghrelin. A subset of neurons in the brainstem senses satiety that turn off primary hunger neurons in another part of the brain. This connection uses the chemical GABA (Martinez de Morentin et al., 2024).

Sleep deprivation affects energy homeostasis and has been associated with perturbed blood levels of peptide hormones. Hunger and appetite increase after a poor night's sleep. Not only do we eat more, we crave the kinds of nutrient-poor, sugary foods that compromise sleep, which leads to more stress on the body and mind which leads to more bingeing which leads to weight gain, increasing our risk of stress and illness which further compromises sleep, mood, and affect. Like this, we can easily fall into a negative feedback loop.

Chronic sleep deprivation can negatively affect immune cells which leads to inflammation and cardiovascular diseases . Losing even an hour and a half of sleep a night potentially increases these risks according to a 2022 study published by researchers at the School of Medicine at Mount Sinai.

Daylight Savings Time (DST) is like a global controlled experiment, asserts sleep researcher Matthew Walker. During the spring, when we lose an hour of sleep, a 24% increase in heart attacks follows that day. In the autumn, when we get an extra hour of sleep, we see a 21% reduction in heart attacks (Gurm, 2018). We see similar patterns in car accidents and suicide rates. Fatal car accidents, attributed to sleep deprivation and circadian misalignment, spike by 6% after DST (Vetter, 2020). Sleep disruptions during the Spring transition are also associated with a 6.25 percent increase in suicide (Osbourne-Christensen, 2022).

Men who sleep five hours or less per night have smaller testicles than those who sleep seven hours or more. Men who sleep five hours or less per night will have a level of testosterone equal to that of men ten years older. Lack of sleep ages a man by a decade. The number of people who can get by on 6 hours of sleep or less without any impairment rounded to a whole number and expressed as a percentage of the population is ZERO, according to Matthew Walker.

Sleep deprivation compromises our immune systems. Natural killer cells (NK) identify pathogens and foreign invaders- such as viruses, bacteria- and destroy them. Reducing sleep to 4 hours is associated with a whopping 70% decrease in NK activity. That is a compromised state of immune deficiency which puts us at risk for acute illnesses like the cold or flu and, over the long term, more serious threats like prostate, bowl, and breast cancer.

Chronic Sleep Restriction (CSR) is defined as sleep durations that are more than four hours but less than seven hours a night. CSR can lead to a range of brain deficits, including impaired attention and learning, and is associated with increased risk of neuropsychiatric disorders and other conditions.

Growing evidence has demonstrated that CSR is linked to a low-grade inflammation, as reflected by increased inflammatory plasma cytokines and by the presence of other markers of inflammation in the brain, such as activation of microglia cells.

Heightened pain sensitivity can result from chronic sleep disruption (CSD)- a condition researchers call CSD-induced hyperalgesia. N-arachidonoyl dopamine (NADA), a type of neurotransmitter called an endocannabinoid, helps manage neuroinflammatory diseases or pain. After a poor night's sleep levels of NADA drop in an area of the brain called the thalamic reticular nucleus. Activity of the cannabinoid receptor 1, also involved in controlling pain perception, decreased as well after sleep was disrupted (Ding, et al., 2023).

Insufficient sleep can lead to the accumulation of intracellular reactive oxygen species (ROS) and/or reactive nitrogen species (RNS), resulting in an unbalance between the oxidant and antioxidant systems of the body. Excessive ROS and RNS levels can cause cellular damage and increased risk of disease.

The very fabric of our lives- our genes and DNA- begin to unravel when sleep is chronically compromised. One study found that after one week of insufficient sleep (6 hours versus 8 hours), 711 genes were up- or down-regulated (Dijk, 2013). Those genes that were down-regulated or switched off were associated with the immune system. Those genes that were up-regulated or switched on were associated with inflammation, tumors, and cardiovascular disease. "Sleep," asserts according to Matthew Walker, "is a non-negotiable biological necessity."

Healthy lifestyle choices, like nutrition, sleep, and exercise improve genetic factors by 62%; unhealthy lifestyle choices, by contrast, increase risks of illness and premature death by 78% (Bian, et al., 2024).

Again, this partially explains why, in some cases, therapy and prescription drugs will not help much- unless they address the fundamentals. I was such a case. I had insomnia and struggled with sleep most of my life. It affected my moods and relationships, contributing to the collapse of my marriage. I was tired all of the time. When I got home after work, I had no energy for my wife. No, I didn't want to go apple picking. No, I didn't want to go on a date night. No, I didn't want to have dinner with her friends. She misinterpreted this as rejection. More than anything, my body craved rest. I wanted to stay home and just nap most days. Two jobs, a strained marriage, and three young children at home taxed me even more, the stress worsening my insomnia which further increased my stress. We went to marriage counseling. My detachment and lethargy were symptoms, not root causes, but we talked in circles about disconnection. Frustrated, my wife filed for divorce. Desperate to get to the root of the problem, I requested a sleep study after my aunt told me that sleep apnea ran in the family.

Obstructive sleep apnea is a serious sleep disorder in which breathing repeatedly starts and stops. This occurs when the throat muscles relax. Loud snoring, episodes in which you stop breathing during sleep, gasping for air during sleep, a dry mouth, difficulty staying asleep (insomnia), excessive daytime sleepiness (hypersomnia), difficulty paying attention while awake, and irritability were some of the symptoms. My doctor did not think I was a candidate initially. Excessive weight and obesity are the most common causes of obstructive sleep apnea. I was athletic and fit. I pressed him anyway and he ordered a sleep study.

I was diagnosed with sleep apnea. In a sense, I was relieved to know there was one condition at the root of so many of my distresses. My wife ignored the diagnosis. The marriage did not end happily, but I walked away with insight. The diagnosis made sense. I could see the exhaustion and the stress and the sadness and irritability that often tormented me within context and in an objective way that appealed to my logical mind. The problem was biological, not moral. It was solvable and reversible, and I was determined to hack my own body and mind to fix this.

With sleep apnea, I control what I can. I sleep well most nights by following the simple protocols listed below. Some tips may be familiar (like sticking to a sleep schedule), and some may be unfamiliar (like sleep tape). What works for me may or may not work for you. Consult with a professional first and experiment for yourself.

Tips on sleep

  1. Exercise daily. 30 minutes of vigorous exercise is best, but even light exercise is better than no activity. Avoid exercising prior to bed as this will stimulate both mind and body. Exercise raises body temperature and body temperature affects sleep. We want to lower our core temperature before bed, not raise it. We also want to lower our heart rate before bed. Exercise raises it. You might consider exercising in the morning. As the sun rises, you may find me running to and from the neighborhood gym. This is intentional. Natural sunlight triggers photosensitive ganglion cells in the retina. This activation primes the superchiasmatic nucleus which sets our circadian clock both globally and at the cellular level.

  2. Use bright light to help manage your circadian rhythmsAvoid bright light in the evening and expose yourself to sunlight in the morning. This will keep your circadian rhythms in harmony with diurnal rhythms. I use blue light blocking glasses. The body produces melatonin, a natural hormone that helps us sleep. Bright lights (whether natural or artificial) tell the body to stop producing melatonin to maintain wakefulness. When we block blue light 2-3 hours before bed (whether naturally or artificially), we sleep easier and longer.

  3. Avoid caffeine 6 or more hours before bed. Caffeine disrupts quality sleep. Some people can drink caffeine before bed and fall asleep- but the sleep quality is poor. As the day progresses, levels of the hormone adenosine gradually increase in areas of the brain that are important for promoting arousal. Elevated concentrations of adenosine inhibit arousal and cause sleepiness. The more adenosine builds up over the course of the day, the sleepier we feel. Caffeine blunts adenosine by binding to the receptor sites. Even though the body is tired, I remain awake long after bedtime if I have a caffeinated drink after 1PM.

  4. Avoid alcohol. Alcohol is a sedative. It blocks REM sleep, which is critical for mental health and recovery. Alcohol also fragments sleep, punctuating it with more awakenings and disturbing the natural cycle. Finally, alcohol contains molecules which promote more nighttime urination which interrupts sleep.

  5. Eating big or spicy meals can cause discomfort from indigestion that can make it hard to sleep. A late meal will raise the body's temperature and heart rate while we sleep. If you can, avoid eating large meals for two to three hours before bedtime. Try a light snack, like kiwi (which has been shown to improve sleep onset, duration, and efficiency) or tart cherries, 45 minutes before bed if you’re still hungry. I fast intermittently. My last meal of the day is between 2 and 4 PM. This gives the digestive system a rest. If I do eat late, I found brisk walking of 20-30 minutes a helpful aid to digestion. As an aside, researchers found that postprandial blood sugar levels (taken after a meal) drop 30-35% after just 10 minutes of walking. Walking does not elevate my heart rate too much, and I can bring it down with breath work before bed. My sleep score (as measured by a wearable) does not fluctuate much when I follow this protocol.

  6. Sugar is a stimulant. I avoid sugary foods. My last meal consists of foods high in tryptophan, a precursor to serotonin, the calming molecule. Kiwi, tart cherry, pumpkin seeds, chocolate, banana, peanuts, oats, bread, and cheese are some foods high in tryptophan.

  7. Sauna. Sauna bathing is associated with many health benefits, from cardiovascular and cognitive health to physical fitness and muscle maintenance (Patrick, 2021). But there's one more benefit: improved sleep. Heat improves circulation, bringing in essential nutrients for repair, and clearing out waste. Heat reduces muscle soreness, helping us relax before bed. Heat increases body temperature which stimulates sweating which cools the body, signaling that it’s time for sleep. Our circadian cycle is controlled by light and the rise and fall of bodily temperature over the day. Sweating isn’t just for cooling off. Studies show that sweating helps eliminate dangerous heavy metals like lead, mercury, arsenic and cadmium from the body. This process, called detoxification, is energy intensive and can cause you to feel sleepy, heavy, and ready for a long sleep. Saunas promotes relaxation of mind, and a relaxed, untroubled mind unwinds with ease and stays asleep.

  8. Hydration is important to our overall health. I drink half my body weight in fluid ounces each day, but stop after about 5PM (preferably before then), as frequent midnight bathroom runs would undermine the health outcomes I'm trying to achieve. I use saw palmetto

Approaching bedtime:

  1. Stick to a sleep schedule- even on the weekends. This helps to regulate your body's clock and helps you fall asleep and stay asleep for the night. If possible, follow Nature's rhythms- wake up before the sun rises and go to bed after the sun sets.

  2. Keep your room temperature cool. According to the Sleep Foundation, the best room temperature for sleep is approximately 65 degrees Fahrenheit (18.3 degrees Celsius). This may vary by a few degrees from person to person, but most doctors recommend keeping the thermostat set between 60 to 68 degrees Fahrenheit (15.6 to 20 degrees Celsius) for the most comfortable sleep. Your core body temperature generally hovers around 98.6 degrees Fahrenheit (37 degrees Celsius), but fluctuates by about 2 degrees Fahrenheit throughout the night. The drop in temperature starts about two hours before you go to sleep, coinciding with the release of the sleep hormone melatonin. During sleep, body temperature continues to fall, reaching a low point in the early morning and then gradually warming up as the morning progresses. Lowering the thermostat at night can work in tandem with these natural temperature fluctuations, signaling to the body that bedtime is approaching.

  3. Practice a relaxing bedtime ritual. My rituals include a gratitude practice, microjournaling as a form of brain dumping, and an autopsy performed on the day that has just passed. I also do 10-20 minutes of stretching (a mix of yoga and qigong) and 10 minutes of breathwork: either a pace of 5.5 breaths per minute for 10 minutes or sama vritti pranayama (commonly called boxed breathing). I found 6 seconds in, a 6 second hold, a 6 second exhalation, and a 6 second hold to be effective at lowering my heart rate. A lower heart rate promotes optimal sleep.

  4. Wind down. Your body needs time to shift into sleep mode. I meditate myself to sleep. Meditation improves sleep and a good night's sleep improves meditative concentration. Meditation has been correlated with decreased sleep onset latency (SOL), or "sleep onset insomnia." SOL can decrease total sleep time. Meditation helps reverse this.

  5. Deep, diaphragmatic breathing with slight breath holds. Because of sleep apnea, my oxygen levels fall at night. Deep breathing techniques help improve oxygen efficiency. Breathing also modulates a wide range of cognitive functions such as perception, attention, and thought structure. During sleep, breathing acts as a pacemaker that entrains the various brain regions and synchronizes them with each other. Respiration coordinates neuronal activity in the hippocampus, medial prefrontal and visual cortex, thalamus, amygdala, and nucleus accumbens by modulating the excitability of these circuits (Karalis, 2022). This coordination is essential for memory consolidation. I use a breathing app called Paced Breathing and set the intervals so that I'm taking 5.5 breaths per minute (5.5 seconds to inhale and 5.5 seconds to exhale). As mentioned, I practice for 10 minutes. Heart rate variability improves- breath and heart rate decrease. Boxed breathing (sama vritti pranayam) is also effective at slowing down the heart rate.

  6. Sleep tape. After reading James Nestor's Breath, I began taping my mouth closed to force nasal breathing. I used a small strip of painter's tape. Within a few weeks, I began to notice a difference in the quality of my sleep. I found this more effective than the CPAP machine- which I eventually discarded. I began sleeping through the night and felt more rested. Oxygen saturation levels are 98-99%. Interestingly, there were fewer, if any, midnight bathroom runs. It's important to note here that I am very health conscious. I would not do this if I were unfit.

  7. Anti-embolism stockings. As we get older, the vascular system becomes less resilient and more porous- which may cause capillary leakage. When we lay down at night, fluids leave extracellular spaces and enter the vascular space which the kidneys will read as an increase in fluids. Peripheral edema tracks with age. Fluids build up in the extremities. Anti-embolism stockings may reduce the frequency of night-time urination.

  8. Avoid electronics before bed or in the middle of the night. Using an electronic device such as a laptop can make it hard to fall asleep, because the particular type of light emanating from screens stimulates the brain. It is best to take work materials, computers and televisions out of the sleeping environment. 

  9. Sleeping pills do not produce naturalistic sleep. Most sleeping pills are classed as sedative hypnotics. Sedation does not give you the restorative natural benefits of sleep. Supplementation may be better.

  10. I found Magnesium L-Threonate somewhat effective. It took less than a week to see benefits. I also supplement with Omega 3 krill oil which improves glymphatic functioning (Ren et al, 2017) and began taking digestive enzymes after my last meal.

  11. Some people, like me, have biphasic sleep patterns. Biphasic sleep describes a pattern of sleep that is divided into 2 phases. I may sleep from 8 to 12 or 2, then I wake up feeling quite alert and unable to return to sleep. When this happens, I take 420mg of magnesium (bisglycinate or glycinate) with chamomile tea which I prepare before bed. Sometimes, I cycle off supplements to avoid plateauing or I will change the regimen slightly. I may add Valerian root, apigenin, or theanine before bed. For mid-morning wake-ups, I may add 900mg of myo-inositol powder or ashwaghanda to my tea and supplement with 5-HTP or melatonin. I will only take melatonin mid-morning, if at all. Again, I cycle off all supplements as often as possible so as not to develop too high a tolerance.

  12. I elevate my feet when I sleep. In addition to improving deep sleep, studies suggest that sleeping with the feet elevated improves circulation (reducing strain on the heart), reduces inflammation, relieves back strain, improves spinal alignment, and improves recovery times.

  13. You may also benefit from recording your sleep in a sleep diary to help you better evaluate common patterns or issues you may see with your sleep or sleeping habits. I use an Oura ring and a Fitbit Charge 4 to track my sleep. There are other popular products like Whoop and smart watches. The data is not as reliable as what one would get from lab-grade equipment, but these wearables are accurate enough and affordable. The data is granular. Sleep is divided into 90 minute ultradian cycles. It shows how long I'm in REM sleep, deep sleep, light sleep and awake. The range for men my age is 15-25% (REM), 12-18% (Deep), 40-60% (Light), and 10-20% (Awake). The higher the percentage of REM and deep sleep, the better the quality. So, I can examine the results and experiment. My average sleep score was 85/100, but has been improving steadily as I continue experimenting and making minor modifications. Recently, I saw a drop in deep sleep, so I focused on improving that metric only. I recorded total time asleep, resting heart rate, sleep efficiency, REM sleep, average blood oxygen levels, lowest heart rate, average heart rate variability, deep sleep, latency (the time it took to fall asleep), room temperature, supplements, and protocols (last meal, what I did to wind down, whether my feet were elevated, blue light exposure, exercise and timing, stressors, sleep tape, etc). Since then, my sleep score has ticked into the 90s.

Sleep Hygiene:

  1. Evaluate your room. Design your sleep environment to establish the conditions you need for sleep. Keep your bedroom cool (between 60 and 67 degrees) and free from noise or light. I use blackout curtains, eye shades, ear plugs, and a "white noise" app.

  2. Sleep on a comfortable, supportive mattress. Quality mattresses have a "life expectancy" of about 9 or 10 years.

  3. If you’re still having trouble sleeping, speak with your doctor or find a sleep professional. I requested a sleep study. Consult with an expert. I can not stress the importance of this enough.

Knowledge is worthless if it is not applied. So, I encourage you to test these protocols and see for yourself. Save yourself time by consulting an expert. May you find what works best for you.
