There is some evidence to suggest that meditation can reduce the need for sleep. A study published in 2010 in Behavioral and Brain Functions found that meditation novices who did a psychomotor vigilance test showed improved reaction times after a 40-minute meditation. The same study also found that experienced meditators slept less than non-meditators. Other sources suggest that meditation can help to improve sleep quality, reduce stress and anxiety, and promote relaxation. However, it is important to note that meditation cannot replace sleep entirely, as sleep is an essential biological process.

What You'll Learn
Meditation improves psychomotor vigilance
Meditation has been shown to improve psychomotor vigilance, which may decrease the need for sleep. In a 2010 study published in Behavioral and Brain Functions, researchers found that meditation novices who performed a psychomotor vigilance test (PVT) after a 40-minute meditation session had significantly improved reaction times compared to before the meditation. This improvement was even more pronounced when the subjects were deprived of sleep the night before the test.
Psychomotor vigilance is a measure of a person's ability to maintain focus and attention over a sustained period. The PVT is a simple test that requires the subject to monitor a LED display and press a button as soon as it lights up. This test is often used to assess how rested a person is, as performance on psychomotor vigilance tasks declines with decreasing amounts of sleep.
Meditation is known to trigger the relaxation response, which activates the parasympathetic nervous system responsible for rest and healing. It also reduces the level of stress hormones in the blood. In addition, meditation alters brain wave patterns, with long-term meditators showing increased gamma wave activity during deep, dreamless sleep. This increase in gamma activity is associated with higher levels of awareness, super-learning, compassion, transcendental states, and spiritual ecstasy.
Surprisingly, even a little practice can go a long way. Meditation novices can improve sleep quality and psychomotor vigilance with as little as 20 minutes of daily meditation. However, more experienced meditators who devote several hours per day to the practice may see a more substantial reduction in their need for sleep.
While meditation can improve psychomotor vigilance and reduce the need for sleep, it cannot replace sleep entirely. Sleep is an essential biological process that our minds and bodies require. However, those who continue to meditate daily may find that they need less sleep over time.

It activates the parasympathetic nervous system
Meditation is known to trigger the relaxation response, which activates the parasympathetic nervous system. This system is responsible for rest and healing. The activation of the parasympathetic nervous system also causes a decrease in stress hormones in the blood.
Professor Herbert Benson discovered the relaxation response during one of the first scientific studies on meditation ever. The relaxation response is a state of profound rest that can be elicited in many ways, including meditation. It is characterised by decreased heart rate, reduced metabolism, and changes to the nervous system that reduce arousal. These changes are similar to those that occur during sleep.
Meditation can be seen as a form of "non-sleep deep rest". The restful alertness experienced during meditation is associated with decreased heart rate, reduced metabolism, and changes to the nervous system that reduce arousal. These changes are similar to those that occur during sleep.
Meditation also improves sleep quality. Even novices to meditation can improve sleep quality with as little as 20 minutes of meditation daily. A study by Ute Hülsheger at Maastricht University found that participants who meditated for 20 minutes each day during two workweeks steadily improved sleep quality, sleep duration, and increased awareness throughout the two weeks.
Meditation can also help to reduce stress and anxiety, which can in turn improve sleep quality. By reducing daily stress, meditation can lead to higher-quality sleep.
Meditation has been shown to reduce the need for sleep. Experienced meditators sleep less on average than non-meditators. A study published in 2010 in Behavioral and Brain Functions found that meditation novices who meditated for 40 minutes had significantly improved reaction times on a psychomotor vigilance test. The impact of meditation was even more significant when the subjects were deprived of sleep the night before the test.
Another study examined the sleeping habits of seven yogis with 2-3 hours or more of practice per day. The yogis slept significantly less than the control group of 23 age and sex-matched non-meditators: 5.2 hours per day compared to 7.8 hours per day. Several other studies have shown similar results.
While meditation can improve sleep quality and reduce the need for sleep, it cannot replace sleep entirely. Sleep is an essential biological process that our minds and bodies desperately need. However, research suggests that once our sleep schedule is balanced, those who continue to meditate daily may need less sleep.

It alters brain wave patterns
Meditation has been proven to alter brain wave patterns, which is one of the reasons why it can reduce the need for sleep.
A 2016 study compared the brain wave patterns of long-term meditators to novices. Long-term meditators showed a significantly lesser need for sleep than the control group. The researchers measured both groups with high-density electroencephalography (EEG), a tool that can measure brain waves with high precision. The researchers found that the brains of long-term meditators produced high-amplitude gamma waves during periods of deep, dreamless sleep. The amplitude of gamma activity correlated with the amount of time they devoted to meditation daily.
The Institute for the Awakened Mind has used EEG to study high-level meditators for decades. They say that gamma activity is associated with the experience of peace, transcendence, and super-lucidity. Furthermore, it is related to high-level awareness, super-learning, compassion, transcendental states, and spiritual ecstasy.
It is noteworthy that experienced meditators produce gamma spontaneously during deep sleep. This implies a long-lasting, plastic effect of meditative training on brain function. It is a trait effect in contrast to a state effect, which is the short-term effect produced directly during practice.
Other studies have shown that meditators have increased amplitude in the theta and alpha bands during sleep. A combination of these frequencies is an indication that the person has conscious contact with areas of the mind that are usually subconscious. That makes dreams more abundant and easier to remember. The Institute for the Awakened Mind associates the theta band with healing.

It raises melatonin levels
Melatonin is a hormone primarily released by the pineal gland at night and is associated with the control of the sleep-wake cycle. Several studies suggest that meditation can impact melatonin secretion and increase the amplitude of the nighttime melatonin peak level.
Meditation is known to trigger the relaxation response, which activates the parasympathetic nervous system responsible for rest and healing. This response also decreases the level of stress hormones in the blood.

Frequently asked questions
No, it cannot replace sleep. Sleep is an essential biological process that our minds and bodies need. However, once our sleep schedule is balanced, those who continue to meditate daily may need less sleep.
Yes, it can. Regular meditation can reduce stress, tension in the body, and mental clutter, all of which hinder sleep.
Yes, it does. If you fall asleep during meditation, it usually means you've reached a state of deep relaxation. While the primary goal of meditation is to work on mindfulness and awareness, falling asleep occasionally is not uncommon, especially if you're practising at the end of the day.
The goal is to incorporate meditation into your daily routine and ease yourself into a restful night. Ideally, you should meditate as close to bedtime as possible. Pair it with soft lighting and a cup of hot herbal tea for an even more soothing effect.
It's hard to say as there are many different factors, but 20 minutes of meditation, plus 10 minutes to get ready, more than make up for 30 minutes of sleep.
