Sleep and mental health are closely linked. Poor sleep is a common symptom of depression, and many antidepressants change how people sleep. So researchers have started to ask a new question: how do psilocybin and sleep affect each other? This article explains what early studies show, from changes in dream sleep on the night after a dose to possible improvements in sleep quality over the following weeks.
This article is for general information only. It is not medical advice. If you have ongoing sleep problems, please speak to a doctor.
Why Researchers Study Psilocybin and Sleep
Sleep helps the brain process emotions and store memories. In addition, many antidepressants reduce rapid eye movement (REM) sleep, the stage most linked to vivid dreams. Researchers therefore wondered whether psilocybin might affect sleep in a similar way, and whether these changes could help explain its potential antidepressant effects. Our guide to psilocybin and the brain explains how psilocybin acts on serotonin receptors.
The Night After Psilocybin: A Czech Sleep Study
In 2020, researchers at the National Institute of Mental Health in the Czech Republic published one of the first controlled sleep studies on psilocybin [1]. Twenty healthy volunteers received psilocybin or a placebo during the day, in random order. Then the team recorded their sleep in a sleep laboratory that night.
After psilocybin, volunteers took longer to reach their first period of REM sleep. There was also a trend toward less REM sleep overall. However, deep sleep, also called non-REM sleep, did not change. The researchers had expected signs of increased brain plasticity during deep sleep, but they did not find them. Interestingly, the delay in REM sleep is similar to what many antidepressants do.
Sleep in the Weeks After Psilocybin
Other research has looked at longer-term changes. A 2024 review combined earlier studies with new data from people who used psilocybin [2]. Both depressive symptoms and sleep problems decreased after psilocybin use, although sleep improved less than mood. Moreover, people who had more severe sleep problems at the start were less likely to see their depression go into remission.
These findings are preliminary. Most of the data came from surveys rather than controlled trials, so the results need confirmation. Still, they suggest that sleep may play a role in how well psilocybin therapy works. Read our article on psilocybin for depression for more on the clinical trials.
Can Psilocybin Disturb Sleep?
On the day of a psilocybin experience, many people find it hard to fall asleep. The effects usually last four to six hours, and people may still feel alert or emotional afterward. Therefore, sessions usually start in the morning or early afternoon. Our article on how long psilocybin lasts explains the timeline.
In addition, a difficult experience can leave people unsettled for a night or two. Talking about the experience and keeping a calm routine often helps. Our guide to handling a bad trip covers this in more detail.
Psilocybin Is Not a Sleep Aid
There is no evidence that psilocybin works as a treatment for insomnia, and nobody should use it as a sleeping pill. For long-term sleep problems, proven approaches such as cognitive behavioral therapy for insomnia (CBT-I) are the best place to start. Good sleep habits, such as a regular bedtime, daylight in the morning and less caffeine and alcohol, also help.
Frequently Asked Questions
Does psilocybin affect dreams?
Research shows that psilocybin can delay REM sleep on the following night, and REM sleep is the stage most linked to vivid dreams. However, the effect on dream content has not been studied well.
Does microdosing help with sleep?
There is no reliable evidence for this. Some people report better sleep while others report worse sleep. See our microdosing guide for more.
When is the best time of day for a psilocybin session?
Clinical studies usually start sessions in the morning, so that the main effects have passed long before bedtime.
Conclusion: Psilocybin and Sleep Research Is Just Beginning
Early studies suggest that psilocybin and sleep are connected. A single dose can delay REM sleep on the following night, and sleep problems may improve along with mood in the following weeks. However, the research is still small and early. To learn more about preparing for a safe experience, read our guide to set and setting.
