Point Disturbance: Impact On Rem Sleep Explored

Sleep is a vital physiological state that accounts for almost a third of our lives. While it may be tempting to use your phone before bed, studies have shown that the blue light emitted by smartphones, tablets, and computers can interfere with sleep by suppressing the production of melatonin, a hormone that helps with sleep timing and circadian rhythms. This can result in neurophysiologic arousals that increase feelings of alertness when you should be winding down.

The blue light from your phone is an artificial colour that mimics daylight, making you feel more alert when exposed to it. Exposure to blue light can affect your internal body clock and throw off your circadian rhythm, which is in tune with light and dark. It can also reduce the amount of time you spend in REM sleep, a stage of sleep considered the most restorative and vital for cognitive functioning.

Research has found a correlation between suppressed levels of melatonin and exposure to blue light, with lower levels of melatonin leading to insomnia, tiredness during the day, and irritability. Additionally, the constant engagement and stimulation provided by smartphones can keep your mind active and engaged, delaying sleep.

To improve your sleep, it is recommended to avoid using electronic devices one to two hours before bedtime and establish a relaxing bedtime routine that does not involve screens.

Marijuana use can decrease the duration of REM sleep

Marijuana use can indeed decrease the duration of REM sleep. REM sleep is the stage of sleep when we do our most active dreaming, and when the brain does a lot of memory processing and consolidation of acquired information, as well as the processing of emotional experiences.

Marijuana, especially THC-rich strains, are likely to reduce levels of REM sleep. This is supported by a 2022 study which found that cannabis strains with higher levels of THC typically reduce the amount of REM sleep. Reducing REM sleep means reducing dreams and, for those who experience PTSD, it could mean reducing nightmares.

The theory is that if you spend less time dreaming, you’ll spend more time in a “deep sleep” state, which is thought to be the most restorative and restful part of the sleep cycle. However, REM sleep is still important for healthy cognitive and immune functioning, and cannabis with higher THC levels could impair your sleep quality if taken long-term.

There is also some evidence to suggest that interrupted REM sleep may have negative effects on mood regulation and memory. Long-term cannabis use may also have unwanted effects on the brain, including difficulty with learning, memory, and focus.

REM sleep is important for healthy cognitive and immune functioning

REM sleep is important for brain development, particularly in infants and children. It is also thought to aid in the development of the central nervous system, which includes the brain and spinal cord. This is why newborns require so much REM sleep.

REM sleep also plays a role in memory consolidation, emotional processing, and dreaming. During REM sleep, the brain prunes its synapses, which are the spaces in which brain cells communicate with one another. This improves memory and problem-solving abilities. It also helps the brain process emotional memories, including those associated with fear.

REM sleep is also important for healthy immune functioning. During the third stage of non-REM sleep, the body takes advantage of very deep sleep to repair injuries and reinforce the immune system.

However, electronic devices such as smartphones, tablets, and computers can interfere with REM sleep by emitting blue light. Blue light suppresses melatonin, a hormone that helps with sleep timing and circadian rhythms. It can also reduce the amount of time spent in REM sleep, which is considered the most restorative form of sleep.

Marijuana use can indeed decrease the duration of REM sleep. REM sleep is the stage of sleep when we do our most active dreaming, and when the brain does a lot of memory processing and consolidation of acquired information, as well as the processing of emotional experiences.

While THC has clear sedative effects, a too-heavy concentration of THC can lead to next-day grogginess. THC-rich strains of marijuana are likely to reduce levels of REM sleep, and this suppression of REM sleep is not healthy. However, it is also possible to experience too much REM sleep, and cannabis is now increasingly recognised as a promising therapeutic tool for sleep disorders associated with abnormal REM sleep and disruptive dreaming, including REM Sleep Behaviour Disorder and PTSD.

A 2022 study found that cannabis strains with higher levels of THC typically reduce the amount of REM sleep. Reducing REM sleep means reducing dreams, and for those who experience PTSD, it could mean reducing nightmares. The theory is that if you spend less time dreaming, you'll spend more time in a "deep sleep" state, which is thought to be the most restorative and restful part of the sleep cycle.

Marijuana withdrawal can cause sleep disturbance

There are several reasons why marijuana withdrawal can cause insomnia. Firstly, users often resort to marijuana to suppress feelings of stress or anxiety. When someone quits marijuana, they no longer have this escape, and stress and anxiety can keep them awake at night. Secondly, many people use marijuana at night as a sleep aid and have become accustomed to this routine. When they quit, they may take longer to fall asleep, sleep less, and have poorer quality sleep. The resulting fatigue can even lead to a relapse as people turn back to marijuana in desperation for a good night's rest.

While most withdrawal symptoms subside within two weeks of quitting, sleep disturbances can last for months if untreated. This includes vivid, life-like dreams that can make it hard to fall back asleep. The risk of developing insomnia during withdrawal is higher for those who have abused marijuana for several years and used strains with high THC levels.

Marijuana use can also 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 long-term use of cannabis with higher THC levels could impair sleep quality.

During marijuana withdrawal, it is important to establish healthy sleep habits and routines. This includes exercising several times a week, maintaining a nutritious diet, and creating a restful sleep environment. While it can be challenging, it is important not to worry about falling asleep and to avoid stimulating devices before bed. If needed, natural sleeping aids can be used, but it is always best to consult a doctor first.

Marijuana can help restore natural sleep cycles

Marijuana can be an effective sleep aid for people with insomnia, chronic pain, PTSD, and restless leg syndrome. It can help people fall asleep faster and improve overall sleep quality. However, it is important to understand the effects of marijuana on sleep and the potential risks associated with its use.

How Marijuana Affects Sleep

Marijuana contains cannabinoids, including tetrahydrocannabinol (THC) and cannabidiol (CBD), which interact with cannabinoid receptors in the brain. THC acts as a sedative and can induce sleepiness, while CBD has a biphasic effect, promoting alertness at lower doses and sleepiness at higher doses.

THC reduces the amount of time spent in the rapid eye movement (REM) stage of sleep, which is associated with dreaming, emotion processing, and memory consolidation. Decreasing REM sleep may reduce nightmares in people with PTSD. However, REM sleep is important for healthy cognitive and immune functioning, and long-term use of marijuana can impair sleep quality.

Choosing the Right Strain

When using marijuana for sleep, it is essential to choose the right strain. Marijuana has two main strains: sativa and indica. Sativa is considered more stimulating, while indica is believed to be more calming and relaxing. However, the effects of these strains may vary depending on the individual.

The ratio of THC to CBD in a strain is also important. Strains with higher levels of THC tend to reduce REM sleep and induce a deeper level of sleep. Strains with higher CBD content may be better for reducing anxiety and promoting sleep at higher doses.

Methods of Consumption

The method of consuming marijuana can also impact its effects on sleep. Smoking or vaping marijuana provides faster onset of effects but may carry risks to the lungs. Edibles, on the other hand, take longer to take effect but may provide more control over dosage.

Precautions and Potential Risks

While marijuana can be helpful for sleep in the short term, it should not be relied upon as a long-term solution. Long-term use of marijuana may negatively impact sleep quality, reduce the amount of time spent in deep sleep, and increase the time it takes to fall asleep. It is also associated with potential health risks, such as an increased risk of chronic bronchitis and changes in brain structure.

It is crucial to consult with a healthcare professional before using marijuana for sleep. They can provide guidance based on your individual needs and medical history. Additionally, marijuana use should be approached with caution, especially for individuals under the age of 25.
