Thc's Impact On Rem Sleep: What You Need To Know

Marijuana use can decrease the duration of REM sleep, which may have implications for cognitive function, memory consolidation, and emotional regulation. REM sleep is important for healthy cognitive and immune functioning, and cannabis with higher THC levels could impair your sleep quality if taken long-term.

Research suggests that THC decreases the amount of time spent in REM sleep, when people spend more time dreaming, processing emotions, and cementing new memories. However, reducing REM sleep may benefit people with PTSD, as nightmares are a common and disturbing symptom.

Some studies have found that daily cannabis users report more sleep problems than occasional users or non-users. However, non-daily users report fewer sleep issues than both daily users and non-users.

THC decreases REM sleep

THC, or tetrahydrocannabinol, is the main psychoactive compound in cannabis. It is responsible for the "high" associated with cannabis use and has a range of therapeutic benefits, including pain relief.

Research has shown that THC is most closely linked to reductions in REM sleep and increases in deep, slow-wave sleep and lighter stages of non-REM sleep. During discontinuation of heavy THC use, sleep disturbance has been detected in users compared to a drug-free control group. THC users showed lower total sleep times and less slow-wave sleep than the control group. They also exhibited worse sleep efficiency, longer sleep onset, and shorter REM latency.

THC-rich strains of cannabis are likely to reduce REM sleep, which can have implications for cognitive function, memory consolidation, and emotional regulation. However, cannabis is now recognised as a promising therapeutic tool for sleep disorders associated with abnormal REM sleep and disruptive dreaming, including REM Sleep Behaviour Disorder and PTSD.

While THC can decrease REM sleep, it is important to note that the effects of cannabis on sleep are complex and depend on various factors, including how it is consumed, the strain, and individual differences.

REM sleep is when we dream

Dreaming is one of the great mysteries of the human experience. Sigmund Freud, the founder of psychoanalysis, said that dreams are a landscape for exploring repressed emotions and unconscious desires.

REM stands for rapid eye movement. During this type of sleep, your eyes move around rapidly in different directions, and your brain activity is similar to its activity when you are awake.

REM sleep occurs every 90 to 120 minutes, and a person may go through up to five cycles of this sleep stage. The first REM cycle is typically the shortest, around 10 minutes, with each subsequent cycle getting longer, up to an hour.

You may spend approximately two hours of sleep dreaming. If you wake up during REM sleep, you are more likely to recall your dream. However, if you don't remember your dreams, it's likely that you are not being woken up during REM sleep.

REM sleep is important for healthy cognitive and immune functioning. During this stage, your brain processes emotions and consolidates memories. It also helps the mind recover from distressing experiences by suppressing them.

While you can dream during all stages of sleep, dreams that are vivid and emotional mostly happen during REM sleep. You are also more likely to experience lucid dreams during this stage.

THC may improve breathing during sleep

THC has sedative effects, and studies have shown that it is most closely linked to reductions in REM sleep and increases in deep, slow-wave sleep and the lighter stages of non-REM sleep.

Synthetic forms of THC have been shown to improve respiratory stability and potentially treat obstructive sleep apnea. However, side effects such as somnolence have been reported in most patients, and the long-term effects on other sleep quality measures, tolerability, and safety are still unknown.

THC-infused drinks, edibles, and other swallowed or sublingual options are considered safer methods of ingestion with fewer side effects than smoking or vaping.

THC can have a stimulating effect for some people

While tetrahydrocannabinol (THC) typically acts as a sedative, it can have a stimulating effect for some people, especially for those who are new to using cannabis or taking higher doses. In these cases, using cannabis before bed may result in a longer time falling asleep.

THC has a biphasic effect on sleep. At lower doses, it can reduce sleep onset latency and has been associated with greater ease of falling asleep, increased slow-wave sleep, and increased total sleep time. At higher doses, THC-predominant cannabis has been shown to reduce total REM sleep and REM density.

THC is the main psychoactive cannabinoid in cannabis and is what gives the high that's associated with cannabis use. It has been shown to have a range of therapeutic benefits, including pain relief.

The effects of THC on sleep may also depend on the route of administration. While smoked cannabis can have bioavailability rates as high as 56%, edibles lose a significant amount of THC through the digestive process, with bioavailability rates of 4% to 20%.

Some people may find that THC helps them fall asleep faster and sleep more soundly, while others may experience longer sleep onset and less REM sleep. The stimulating effect of THC on some individuals may be due to its interaction with cannabinoid receptors in the brain, which can result in increased levels of sleep-promoting adenosine and suppression of the brain's arousal system.

It is important to note that the effects of THC on sleep can vary from person to person, and more research is needed to fully understand the impact of THC on sleep architecture and overall sleep quality.

CBD may reduce symptoms of REM sleep behaviour disorder

CBD, or cannabidiol, is a non-psychoactive cannabinoid found in the cannabis plant. Unlike THC, CBD does not produce a "high" and is commonly used to reduce pain and anxiety. While research on CBD is still ongoing, it is believed to have a calming effect on the nervous system and can help with sleep disorders such as insomnia.

CBD has been found to be effective in reducing symptoms of REM sleep behaviour disorder (RBD). RBD is a parasomnia characterised by the loss of muscle control during REM sleep, often leading to nightmares and active behaviour during dreaming. In a case study, four patients with Parkinson's disease who were treated with CBD experienced a significant reduction in the frequency of RBD-related events without any side effects.

CBD appears to promote alertness at lower doses and sleepiness at higher doses. It is important to note that CBD products may contain varying levels of THC, which can influence the effects experienced. Additionally, CBD can interact with other medications, so it is essential to consult a doctor before use.

While CBD shows promise in treating sleep disorders, more research is needed to fully understand its effects on sleep architecture and specific sleep stages.
