Sleep is a cornerstone of both Mental Health and physical health. Getting better sleep is one of, if not the most powerful tool for your well-being.
Before going down the route of highly detailed sleep optimization through the addition of supplements and tech gadgets, make sure you have the fundamentals: a consistent sleep schedule, wind-down routine and sleep environment. These good sleep habits lay the groundwork for quality rest.
Perfection isn’t necessary — almost every adult experiences sleep problems at some point, and stressing too much over your sleep patterns can cause anxiety that will make it even harder to fall and stay asleep. Prioritizing the QQRT fundamentals (quantity, quality, regularity and timing) at least 80% of nights is sufficient. Life happens, and it’s important to embrace meaningful experiences like dinners, concerts and time with friends. If you’re going to have a late night, let it be for something that adds value and enjoyment to your life.

The Science of Sleep
Good sleep refers to both quantity and quality of sleep, including factors such as how long it takes you to fall asleep, how often you wake throughout the night and how you move through different sleep cycles of rapid eye movement (REM) and deep sleep. Deep, non-REM sleep occurs predominantly in the first half of the night and is particularly important for cognitive processes such as memory consolidation, metabolic regulation and immune function. As you move through subsequent 90-minute sleep cycles ( means approximate), your brain spends a higher proportion of time in REM sleep, which plays a critical role in emotional regulation and creative problem-solving. Sleep is governed by two primary systems: the homeostatic sleep drive controlled by adenosine buildup, which increases sleep pressure the longer you’re awake, and your overall circadian rhythm, regulated by the suprachiasmatic nucleus (SCN) in the brain, which is highly influenced by viewing sunlight.

Shift Work, Jet Lag and Sleep Deprivation
Shift work, jet lag or a night of poor sleep all cause short-term shifts in the body’s natural circadian rhythm (the body’s natural sleep/wake cycle). Increasingly, more people are falling into the category of shift work behavior, even if they’re not traditional shift workers — for example, staying up late to play video games or watch TV, or frequently shifting their bedtime and wake-up time by several hours.If you experience occasional sleep deprivation, the key is to maintain your usual schedule and not overcompensate for lost sleep with additional naps or caffeine. The physiological stress caused by a constantly shifting sleep schedule (analogous to frequently changing time zones) leads to negative overall health effects. If you have to keep an irregular sleep schedule, harness the tools and protocols we already know to influence and train your circadian rhythm — including natural light exposure, consuming caffeine only in specific windows, meal timing and regular exercise.

How to Get Better Sleep
From the time you get out of bed in the morning, your behaviors and environment influence how easily and deeply you will sleep later that night. During daytime hours, prioritize morning sunlight, keep naps at ~20 minutes or less and eliminate afternoon/evening caffeine intake. In the evening, minimize light exposure by reducing screen use and opting for relaxing activities like reading or meditating instead of watching the news or scrolling social media. Nothing can fully replace lost sleep, but getting a less-than-ideal amount of sleep on a consistent sleep schedule is better for your health than seesawing between nights of little to no sleep and late mornings to try to compensate. Whether you choose to implement a range of protocols or just focus on going to bed at the same time each night, you will see the benefits of better sleep.

Optimizing Your Sleep Environment
Small adjustments to your surroundings can improve your sleep quality without requiring major effort. Start by dimming overhead and bright lights in the evening to reduce blue-light exposure. Keeping your bedroom cool will allow your body temperature to decrease the one to three degrees needed in order to transition to sleep effectively. Minimizing noise by using earplugs or listening to white noise can also help (aim for less than 30 decibels, dB, even when using white noise) and avoiding strong fragrances prevents sleep disruptions from poor air quality. For additional support, red-lens eyewear (like Roka glasses*) can block blue light when dimming isn’t an option, and HEPA filters will improve air quality and reduce allergens. Advanced tools like cooling mattress covers (like those from Eight Sleep*) and air-quality monitors can help ensure a consistent environment that supports restorative, quality sleep. These devices are certainly helpful but not essential — a more supportive sleep environment is achievable with even small changes.*Roka and EightSleep are Huberman Lab sponsors.

Supplements for Relaxation and Sleep
To get the most out of sleep supplements, your body and mind should already be moving toward relaxation and rest. Unlike prescription sleeping pills that artificially induce sleep, supplements can’t force a shift from wakefulness to sleep, but they can support and accelerate the natural transition to a good night’s sleep when the groundwork has been laid. Magnesium (in the form of magnesium threonate or bisglycinate) increases GABA levels, which in turn reduces neuronal excitability and promotes relaxation and drowsiness. L-theanine is another sleep supplement which increases GABA and when taken 30 to 60 minutes before bedtime has been shown to reduce anxiety and stress levels. Myo-inositol can improve sleep by increasing serotonin levels and can also have a sedative effect, making it easier to fall back asleep. Both myo-inositol and L-theanine can also be taken during the day to reduce feelings of anxiety and contribute to a general sense of calm.

Sleep Disorders
Everyone will experience occasional sleep deprivation — it’s par for the course for a human with a busy life. Frequent waking during the night (waking once is normal), an inability to fall asleep or fall back asleep, or consistently feeling fatigued throughout the day can be indicative of chronic suboptimal sleep or a medical sleep disorder.While a single night of poor sleep is often the result of environmental factors like consuming caffeine too late in the day, extensive short-wavelength light exposure (blue and green light), or a change in sleep timing, sleep disorders like chronic insomnia and sleep apnea likely require medical intervention. If you experience persistent symptoms or are concerned you’re not getting enough hours of sleep (7-9 for most adults) or sufficient sleep quality, it’s crucial to consult a health care professional or sleep specialist to investigate further.

Non-Sleep Deep Rest (NSDR) and Naps
Both non-sleep deep rest (NSDR) and naps can boost energy levels during the day. NSDR can also be used at night to fall asleep faster or when you are unable to get back to sleep. NSDR protocols and yoga nidra practices are meant to induce a state of deep relaxation. Brain activity during an NSDR practice mimics the activity seen during sleep, allowing you to get the benefits of restorative sleep without having to fall asleep completely and without interfering with nighttime sleep. Even a brief, 10-minute NSDR session can help replenish dopamine levels and increase feelings of alertness afterwards. Some people find daytime naps to be restorative, yet others may find they awake from a nap feeling more tired or irritable than before or notice it affects their sleep at night. If you like taking naps, a short 20-to25-minute nap can replenish energy levels. A longer nap (90 minutes or less) can be helpful if you are particularly sleep-deprived. However, try to keep naps to the earlier part of the day.

FAQ
What is QQRT, and how does it help improve sleep hygiene?
QQRT stands for Quantity, Quality, Regularity and Timing, the four healthy habits essential for good sleep, as explained by Dr. Matthew Walker:Quantity: Refers to the appropriate duration of sleep, typically 7-9 hours per night for adults.Quality: Focuses on how uninterrupted and efficient your sleep is, with a high sleep-efficiency score (ideally above 85% on your sleep-tracking device) indicating most of your time in bed is spent asleep, not awake.Regularity: Emphasizes maintaining consistent (within 30-45 minutes) bedtimes and wake-up times daily to support your body’s natural sleep/wake cycle.Timing: Involves understanding your chronotype (whether you’re a morning or evening person) and aligning your sleep schedule to match your biological preferences.By optimizing these four factors, you can significantly enhance your overall sleep hygiene and health.

Is it normal to wake up in the middle of the night?
Waking up in the middle of the night can be a normal part of the sleep cycle, particularly during lighter stages of non-REM sleep. Most people experience brief periods of wakefulness throughout the night as they transition between different sleep stages. However, if these awakenings are frequent, prolonged or cause difficulty falling back asleep, it may indicate an underlying issue. Also, if you wake up once during the night to urinate, this is normal, however with age this can lead to more frequent awakenings that may disrupt sleep.Waking up in the middle of the night can be a normal part of the sleep cycle, particularly during lighter stages of non-REM sleep.

How do I know if I’m getting good sleep?
To assess if you are getting enough sleep and your sleep quality is good, consider these key indicators:You feel emotionally and physically rested upon waking. If you still feel groggy or unrested after being awake for a couple of hours, it may indicate poor sleep quality.You can stay alert throughout the day without relying heavily on caffeine or naps.You have high sleep efficiency — meaning most of the time you spend in bed, you’re asleep.You feel tired at your usual bedtime each day.You keep your daily bedtime and wake-up time consistent, even on weekends. If not, this is analogous to changing time zones on the weekend — this makes waking up on Monday morning particularly difficult.If your alarm clock didn’t go off in the morning, would you sleep past your scheduled wake-up time? If so, it means you’re very likely not getting sufficient sleep. Sleep trackers/wearable devices can be helpful in determining sleep behaviors and patterns during the night. It’s important, however, not to fixate too much on your “sleep score” or other metrics, which can lead to orthosomnia — an obsession with sleep health that can cause anxiety and conversely have a negative impact on the quality of your sleep. It’s best to use any wearable, gadget or device for directional guidance, and instead prioritize how your mind and body feel.To assess if you are getting enough sleep and your sleep quality is good, consider these key indicators:You feel emotionally and physically rested upon waking.

What are the health risks associated with chronic sleep deprivation?
According to the American Academy of Sleep Medicine, long-term sleep deprivation negatively impacts both mental and physical health, and can increase the risk of anxiety, symptoms of depression, obesity, diabetes and heart disease. Even a short period of sleep deprivation can have negative effects on memory, emotional regulation, mood and decision-making. Many, if not most, adults are not getting enough sleep —- so much so that the US Centers for Disease Control and Prevention (CDC) considers sleep deprivation as a public health epidemic. Keep to your daily bedtime like you would any of your other daily non-negotiables.According to the American Academy of Sleep Medicine, long-term sleep deprivation negatively impacts both mental and physical health, and can increase the risk of anxiety, symptoms of depression, obesity, diabetes and heart disease.

Are naps beneficial? Will they negatively affect my sleep?
There is no one-size-fits-all answer. Some people find an early afternoon nap to be highly beneficial (some cultures even have afternoon naps scheduled into their work day — like a Spanish or Mexican siesta), and yet others either can’t manage to fall asleep during the day, wake up feeling worse off than before, or can’t fall asleep later at night. There is no universal benefit to napping — if it works for you, great. If not, there are still tools and protocols that can help you with afternoon energy, including a short NSDR protocol or delaying caffeine intake in the morning to prevent an afternoon crash.If you choose to nap, try to keep your naps under 25 minutes to avoid entering a sleep cycle, or around 90 minutes to allow yourself to complete a full sleep cycle. However, you’ll have to experiment with this second approach as many find it difficult to fall asleep later that night without sufficient “sleep pressure” that could be reduced by a long nap. Waking up in the middle of a sleep cycle can be difficult due to sleep inertia, or you may wake up feeling irritable.There is no one-size-fits-all answer.

I know I have a late night coming up — how can I prepare beforehand and recover the next day?
The most important factor in overall sleep health is long-term consistency: keeping bedtimes and wake times the same daily, with only 30-45 minutes of variance each day. However, occasionally experiencing a worthwhile late night isn’t going to destroy your sleep schedule and shouldn’t deter you from engaging in fulfilling social activities or events.In the days leading up to your expected late night, try to maintain your regular sleep schedule as much as possible. The day of, you can prepare your bedroom so that when you do get ready for bed, you can transition to sleep as easily as possible. Importantly, the next morning, don’t change your schedule. Wake up within an hour of your regular wake-up time — even if it means a reduced amount of sleep. Instead of drinking more caffeine than usual to feel more alert, use a protocol that naturally increases feelings of alertness, such as sunlight exposure, a vigorous workout or a short NSDR practice.

What role does melatonin play in sleep?
Melatonin is a hormone secreted by the pineal gland in response to darkness and is integral to regulating the body’s circadian rhythm. The secretion of melatonin follows a circadian pattern, with levels rising in the evening, peaking during the night, and falling in the early morning. Light, especially blue light from screens and phones, can inhibit melatonin secretion, thus delaying sleep onset and shifting the circadian phase and making it harder to fall asleep. While melatonin supplements might be helpful for short-term issues like jet lag or adjusting to shift work, they should not be relied upon for chronic sleep disturbances, and are often sold in supplements in doses that are too high or even counter-productive. Take extra caution with melatonin supplementation in children as it has potential to interfere with hormonal development; consult with a healthcare professional..
What is proper sleep hygiene?
Sleep hygiene practices promote consistent and restorative sleep. Good sleep hygiene doesn’t just start at bedtime — it’s about implementing healthy sleep habits throughout your daily routine that will make it easier to fall asleep at night.Specific protocols include limiting exposure to bright light from electronic devices in the evening, avoiding late afternoon naps and stimulants like caffeine and setting up your sleep environment to support sleep through reducing noise (ideally below 35 dB) using earplugs or white noise, lower temperatures, total darkness (using blackout curtains or an eye mask and opting to read a book or listen to music at night instead of consuming highly stimulating content, such as the news, social media or politics.Poor sleep hygiene can be summarized as an inconsistent bedtime routine where sleep is treated as an afterthought to your waking hours.Sleep hygiene practices promote consistent and restorative sleep.

How many hours of sleep do I need each night?
Most adults require between 7-9 hours of sleep per night for optimal cognitive and physical function, though individual variations exist. FYI: most people overestimate how much sleep they’re actually getting each night and underestimate how much sleep they actually need. Just as more sleep isn’t the same as good sleep, even if you are reaching deep, restorative sleep, you still need to sleep an adequate amount per night. For women, sleep patterns and sleep efficiency are significantly influenced by hormonal fluctuations throughout the menstrual cycle and menopause, making it important to aim to sleep a sufficient duration each night.Most adults require between 7-9 hours of sleep per night for optimal cognitive and physical function, though individual variations exist.
