    Do you ever wonder what happens when you sleep high? If you’re wondering about this question, this article will explore the altitude effects of sleeping while under the influence of marijuana.

    You may already know that marijuana can induce relaxation and sleepiness, making it a popular natural sleep aid. However, it’s important to understand the potential risks and drawbacks.

    From impaired sleep quality to disruption of REM sleep, there are factors to consider before incorporating marijuana into your bedtime routine.

    Key Takeaways
    Different strains of marijuana have different effects on sleep, with high CBD strains making it easier to fall and stay asleep, and high THC strains increasing time in deep sleep stages.
    Marijuana use can reduce the duration of the REM sleep stage, which may be beneficial for individuals with PTSD.
    The terpene myrcene plays a role in the sedating effects of marijuana, with strains high in myrcene tending to have more sedating effects.
    Indica strains are commonly associated with sedation, but sativa strains can also induce sleep.
    The balance between indica and sativa genetics can influence sleep effects.

    Understanding Marijuana and Sleep

    Marijuana, commonly used interchangeably with Cannabis, is a part of the Cannabis Sativa plant that carries a substantial amount of tetrahydrocannabinol (THC) [1].

    When it comes to the effects of different cannabis strains on sleep, the key factor to consider is their potency. Cannabis strains vary in their levels of THC and CBD, which are the main compounds responsible for the high and therapeutic effects. 

    Indica strains, known for their relaxing properties, are often recommended for sleep. These strains can help you unwind and prepare for a restful night. On the other hand, sativa strains are believed to be more energizing and may not be as effective for sleep.

    Mechanisms of How Weed Makes You Sleepy

    When you smoke weed, cannabinoids in the marijuana plant bind to cannabinoid receptors in your brain. This binding increases the levels of adenosine, a neurotransmitter that promotes sleepiness, while also repressing the arousal system [2].

    THC, one of the main cannabinoids in cannabis, is believed to be responsible for the sedative effects of weed. However, it’s worth noting that THC can also stimulate some individuals. Additionally, CBD, another cannabinoid, can promote alertness in lower doses and sleepiness in higher doses. The combination of THC and CBD can make it easier for some people to fall asleep.

    These mechanisms contribute to the sleep-inducing effects of cannabis when you use it to fall asleep.

    Safety and Dependence on Cannabis for Sleep

    Using cannabis for sleep can have both benefits and risks. While it may help improve sleep quality for some individuals, there are potential risks and side effects to consider.

    Relying on cannabis as a sleep aid may result in dependence, making it challenging to get restful sleep without it. Additionally, there’s a possibility of experiencing symptoms of insomnia when not using cannabis products.

    It’s crucial to be aware of the risks and side effects associated with using cannabis for sleep. Before deciding on using it for sleep, consult with a medical professional.

    Effects of Weed on REM Sleep

    While using weed, the effects on your REM sleep may vary. Cannabis smokers tend to spend more time in the previous stage of sleep, resulting in less REM sleep. This reduction in REM sleep can hinder the body’s ability to rest and recover. 

    On the other hand, cannabis may improve sleep in individuals with REM sleep behavior disorder. Different strains of cannabis have different effects on sleep, with strains high in THC increasing time spent in deep sleep stages and reducing the length of the REM sleep stage.

    However, it’s important to note that the impact of weed on REM sleep is still not well-studied, and further research is needed to determine the exact effects.

    Potential Benefits of Cannabis Use

    Some research has found that the use of cannabis may be helpful in treating various health conditions such as:

    Chronic pain

    Cannabis has been used for a long time for pain management. Based on a 2016 survey that was conducted in Colorado, United States, over 65% of respondents reported using cannabis to relieve pain and found that it was helpful. Out of these respondents, 80% reported that it was helpful compared to over-the-counter pain medications [3].

    A few other studies have also found that cannabis can be useful in treating neuropathic pain— a pain that is caused by nerve damage [4].

    Anxiety

    Anxiety disorders are one of the most common psychiatric conditions, with up to a lifetime prevalence of 30%. In Australia, anxiety is the second most common condition to be prescribed medical marijuana [5]. According to a study that was conducted by CU Bolder, all of the group participants reported feeling less tense and decreased anxiety [6].

    Epilepsy

    Research also shows that pharmaceutical-grade CBD can be effective in treating epilepsy, more specifically, rare and severe forms of epilepsy known as Dravet syndrome and Lennox-Gastaut syndrome [7].

    Sleep disorders

    Some evidences prove cannabis to be beneficial for short-term sleep problems, including insomnia symptoms, trouble sleeping, and sleep disturbances. Sleep psychologist, Dr. Deirdre Conroy, from the University of Michigan Health affirms that marijuana can help people fall asleep faster and improve sleep quality, especially in the first part of the night [8].

    However, using marijuana continuously may hurt health in the long term. According to a new survey by the American Academy of Sleep Medicine (AASM), it has been reported that over half of Americans who use marijuana have lost sleep over it [9]. Another study that involved adults aged 20 to 59 years old had results that indicated the use of cannabis is associated with increased difficulty falling asleep and excessive daytime sleepiness [10].

    Potential Side Effects of Marijuana on Sleep

    Factors that can affect the quality of your sleep when using marijuana include the potential side effects of the drug. Here are some potential side effects that you should be aware of:

    • High doses of THC can increase anxiety and paranoia, negatively impacting sleep
    • Energizing strains with lower myrcene content can be stimulating and may affect sleep.
    • Paranoia and anxiety are side effects of smoking too much THC.
    • Withdrawal symptoms are associated with stopping marijuana abruptly.

    It’s important to pace yourself and avoid smoking certain strains past mid-afternoon.

    What happens to your brain when you sleep high?

    The use of cannabis affects brain development and brain function. Within 24 hours of using it, you can witness an impact on your thinking, attention, memory, coordination, movement, and time perception.

    When you sleep high, your brain activity will slow, and you may find yourself being able to fall asleep faster and experiencing increased deep sleep [11].

    Alternatives to Help You Fall Asleep Faster

    Although marijuana can help some individuals fall asleep faster, it does come with certain risks and side effects, which are not great in the long term. Thankfully, it is not the only option.

    If you are looking to avoid the side effects and try out other natural alternatives to fall asleep, here are some effective ones to help you drift off faster and sleep better:

    • Limit blue light exposure: Blue light can interfere with the production of melatonin. Melatonin is a hormone that helps induce sleep. The lesser amount of melatonin produced means the more awake you’d be.
    • Create a consistent sleep schedule: Create a consistent sleep schedule by going to bed and waking up at the same time each day, even on the weekend. Doing so will help to regulate your body’s circadian rhythm.
    • Guided meditation and breathing exercises: Mindfulness-based techniques can slow racing thoughts and prepare your body to sleep. Apps such as ShutEye® offer several calming guided meditations and sleep sounds to help you ease into sleep naturally.
    • Establish a bedtime routine to wind down: Creating a relaxing bedtime routine can also help signal to your body when it is time to wind down for bed. You can try reading a book, taking a warm bath, or doing light stretches such as yoga.

    Conclusion

    While marijuana can help with sleep, there are also many risks. It may be a tempting solution. However, it’s best to always opt for more natural remedies or seek professional help.
