LSD is a powerful psychedelic drug that can significantly impact sleep patterns and the overall quality of sleep. It is known to lengthen the REM stage of sleep, which can lead to negative experiences such as nightmares and hallucinations, both while asleep and awake. This disruption to sleep patterns can have flow-on effects to mental and physical health, and may even trigger a bad trip, inducing paranoia, fear, and even PTSD. While the effects of LSD on sleep are well-documented, the complex nature of neuroscience means that much remains to be understood about the specific mechanisms involved. Recent studies have also explored the impact of microdosing LSD, suggesting that it may increase sleep duration the night after ingestion, without affecting the quality of sleep on the day of dosing.

What You'll Learn
LSD lengthens REM sleep
LSD, or d-lysergic acid diethylamide, is a psychedelic drug that can induce hallucinations and sensations like synesthesia. It is often referred to as "acid" on the street. While LSD is known for its psychotropic effects, it can also have negative impacts on sleep due to its influence on brain chemistry and serotonin levels.
One of the key ways LSD affects sleep is by lengthening the REM (Rapid Eye Movement) sleep stage. REM sleep is a critical period during sleep where the eyes scurry behind closed eyelids and the brain becomes highly active, often resulting in vivid dreams. Typically, the body naturally transitions in and out of REM sleep throughout the night, with each phase gradually lengthening. However, LSD has been found to prolong the duration of REM sleep.
Neuroscience and Therapeutics explains that even low doses of LSD can increase the REM sleep period by up to 240%. This means that too much of an individual's sleep time is spent in the REM stage, which can lead to an imbalance in their sleep architecture. As a result, they may experience nightmares, hallucinations, and increased feelings of fear while asleep or even when awake.
The impact of LSD on REM sleep has been observed in various studies. For example, a study by Muzio et al. (1966) found evidence of prolonged REM sleep periods at certain doses of LSD. Additionally, a study on sleep-deprived men by Safer (1970) noted that the administration of LSD after one or two nights of sleep loss resulted in attention impairments and inaccuracies in problem-solving and vigilance tests.
The alteration in the nocturnal sleep cycle caused by LSD can have significant implications for overall health and well-being. Disruptions in sleep patterns can increase the likelihood of getting sick, experiencing depression or anxiety, and potentially lead to the use of other harmful substances to counteract the effects of LSD on sleep. Therefore, it is crucial to understand the risks associated with LSD use and seek professional help if needed to restore healthy sleep patterns and overall well-being.

REM sleep disinhibition causes nightmares
LSD is a hallucinogenic drug that can significantly impact sleep patterns and the quality of sleep. It is known to lengthen the REM stage of sleep, which can lead to negative experiences such as nightmares, fear, and hallucinations. This occurs because LSD alters serotonin transmission, affecting the sleep/wake cycle. Serotonin is a vital chemical for regulating sleep, and any drug that disrupts its levels will impact a person's sleep architecture, or the stages of sleep they cycle through.
REM sleep behaviour disorder (RBD) is a condition where individuals physically act out their dreams while in the REM stage of sleep. This can result in mild muscle twitches, shouting, or even violent movements that can cause injury to oneself or one's bed partner. While the symptoms of RBD can vary in severity, the disorder is often characterized by nightmares and vocalizations. Treatment options for RBD include melatonin, clonazepam, and pramipexole, which can help reduce the occurrence of nightmares and other symptoms.
When LSD ingestion causes REM sleep disinhibition, it can lead to an increased likelihood of experiencing nightmares. This is because the body spends more time in the REM phase of sleep, which is when vivid dreams typically occur. As a result, individuals may experience unpleasant side effects during sleep and upon waking, including paranoia, fear, and even PTSD.
The impact of LSD on sleep can have broader consequences on mental and physical health. Disrupted sleep patterns can increase the risk of illness, depression, and anxiety. Furthermore, individuals may turn to other harmful substances or sleep aids in an attempt to counteract the effects of LSD on their sleep, further complicating recovery and sleep habits.
While LSD can have significant impacts on sleep, it is important to note that any drug has the potential to disrupt sleep schedules and patterns. Drugs can keep individuals awake or make them sleepy at odd times, influence dreams, and impact sleep health. Understanding the specific effects of LSD on REM sleep disinhibition and the resulting nightmares can help inform harm reduction strategies and highlight the importance of seeking support for substance use disorders.

LSD affects sleep architecture
LSD, or d-lysergic acid diethylamide, is a psychedelic drug that can induce hallucinations and sensations like synesthesia. It can also lead to negative sleep-related side effects. LSD's effects are commonly described as psychotropic, changing the way one perceives the world. This perception shift is often referred to as a “trip” and can include auditory and visual hallucinations, as well as sensations that aren't real.
The exact mechanisms of how LSD affects sleep architecture are still being explored, but it is known that LSD interacts with the serotonin system and modulates neural oscillations, altering sleep patterns, particularly during REM sleep. LSD lengthens the REM period of sleep, with even low doses increasing it by up to 240%. This increase in REM sleep can lead to negative experiences, such as nightmares, fear, and hallucinations while asleep or awake. These side effects can impact an individual's mental and physical health, potentially leading to a higher risk of illness, depression, or anxiety.
While LSD has been associated with negative sleep-related side effects, there is also emerging research suggesting that it may have therapeutic benefits for certain sleep disorders. Some studies indicate that LSD may reduce nightmares and improve overall sleep patterns, making it a promising candidate for addressing sleep disturbances in those with PTSD. Additionally, the ability of LSD to induce a state similar to REM sleep may have implications for emotional recalibration, potentially treating conditions like post-traumatic stress disorder, depression, and anxiety.
The complex interplay between LSD and sleep architecture highlights the need for further research. While LSD may offer therapeutic benefits for some, its negative side effects on sleep cannot be ignored. Understanding the full range of LSD's effects on sleep architecture is crucial for developing safe and effective treatments.

Sleep problems are a sign of substance use disorder
Sleep problems are a common symptom of substance use disorder (SUD). SUD is associated with insomnia, which is characterised by difficulty falling or staying asleep. This can lead to a state of "hyperarousal", increasing the risk of drug abuse. Additionally, certain substances can interfere with the sleep stages, reducing the amount of non-rapid eye movement (NREM) sleep, which is crucial for deep sleep.
Drugs and alcohol can also impact REM sleep, leading to strange dreams and restless legs syndrome. During withdrawal, individuals may experience rebound insomnia and elevated REM percentages, shortened latencies to REM sleep, and higher REM densities. These sleep disturbances can persist for months or years into recovery and are common during withdrawal from alcohol, opioids, cocaine, and marijuana.
Research has found that LSD specifically affects REM sleep, increasing it by up to 240%. This can result in nightmares, hallucinations, and negative impacts on mental and physical health. Studies have also shown that sleep-deprived individuals who take LSD experience more rapid onset of its characteristic behavioural and attention impairments.
Microdosing with LSD, however, has been found to increase sleep duration by 24.3 minutes on the night after dosing, without affecting the proportion of time spent in various sleep stages or physical activity. While microdosing may offer potential therapeutic benefits for mood disorders characterised by sleep disturbances, it is important to recognise that any drug use can disrupt sleep schedules and have broader impacts on health and quality of life.

Microdosing LSD increases sleep duration
LSD is a psychedelic drug that can have a significant impact on sleep. It interacts with proteins on the surface of the brain, changing the amount of serotonin present. Serotonin is a vital chemical in managing the sleep/wake cycle, so LSD users will experience changes in their sleep patterns.
While most drugs are known to shorten REM sleep, LSD has the opposite effect, lengthening it. This can lead to nightmares and hallucinations, causing negative experiences and affecting mental and physical health.
However, microdosing LSD has been found to increase sleep duration. A Phase 1 randomized controlled trial found that participants who microdosed LSD slept an extra 24.3 minutes per night compared to those on a placebo. There were no changes in the proportion of time spent in various sleep stages or in participant physical activity.
Another study by Muzio et al. administered low doses of LSD just before or one hour after participants went to sleep. This study also found that LSD significantly increased REM duration, with REM bursts interrupting slow-wave sleep.
While the effects of microdosing on sleep are still being studied, the available evidence suggests that microdosing LSD can indeed increase sleep duration.
