Every human being, from time to time and for various reasons, can suffer from lack of sleep. Sporadic isolated instances of sleep deprivation are rarely cause for alarm. But for some, chronic patterns of sleep deprivation, or even diagnosed sleep disorders such as insomnia or narcolepsy, have far reaching consequences.
Because rest is so essential to productivity in many areas of life, it's encouraging to see new treatment options emerge. One such option is cannabidiol (CBD) oil, which has a number of positive effects on sleep patterns. This article will explore the risks of chronic sleeplessness and then demonstrate how the treatment option of CBD has been the answer for many.
According to the popular website WebMD.com, there are some surprising and serious effects to chronic loss of sleep. Here are ten of them: (1)
Typically, physicians will do one of two things with regard to sleep deprivation. First, they usually prescribe narcotics to induce and maintain sleep. However, these narcotics interfere with normal brain activity needed to process and empty various parts of the brain. The second thing physicians do is treat the symptoms of sleep deprivation without ever addressing the root cause.
CBD provides an all-natural alternative to strong medications to restore and maintain healthy sleep patterns. Delving into how the brain works during sleep provides a better understanding of these wake and sleep patterns and how CBD has a positive impact on multiple fronts.
According to the website howsleepworks.com there are two distinct stages of sleep. REM (Rapid Eye Movement) sleep occurs in cycles of about 90-120 minutes throughout the night.(4) It dominates the latter half of the sleep period in the hours just before waking. REM sleep also separates multiple stages of deeper sleep. This stage is characterized by the side-to-side movements of the closed eyes. It's believed this stage is associated with brain wave rejuvenation in different parts of the brain than a deeper sleep.
Non-REM sleep provides for deeper relaxation and rejuvenation of different parts of the brain. The cycles of non-REM sleep produce stronger and lower brain waves and they are separated by cycles of REM sleep. There are 5-6 cycles in an 8 hour period of sleeping, with each cycle fulfilling a distinct physiological and neurological function necessary for the health and wellness of the body.
This is important to note because most sleeplessness occurs during the REM cycles of brain function, when individuals can awaken between deeper sleep cycles and be unable to fall back to sleep.
Research indicates that CBD has a positive effect for those who suffer from sleep disorders. In particular, it appears to block REM sleep in a way that keeps individuals asleep who are susceptible to waking during these lighter sleep cycles.(5)
CBD oil contains anxiolytic (anxiety-inhibiting) properties that block REM sleep. So rather than direct sleep regulation as say, a narcotic would have, CBD impacts the brain function by leveling out the brain activity most likely to cause awakening events in REM sleep cycles.
In a small, but significant study of 15 insomniacs, CBD dosages were administered in varying amounts. Those receiving the highest dosage noted significant increases in sleep, and less dream recall, which is an indicator of deeper sleep.(6)
Up-/down-state transitions are a form of network brain activity observed when sensory input into the cortex is diminished during non-REM sleep.(7) Up-states during sleep occur from coordinated signaling between brain synapses and are modulated by systems that affect the balance between inhibition and excitation.
The endocannabinoid (EC) system, a neuromodulartory system intrinsic to the brain's microcircuitry, is a critical regulator of up-states and sleep. Activation of the cannabinoid 1 receptor (CB1) with exogenous agonists by blocking metabolism endocannabinoids, increased up-state amplitudes and facilitated action potential discharge during up-states. The interesting result is that the synaptic signaling in the brain that misfires and results in sleeplessness saw a marked decrease in both the amplitude and frequency of the spiking brainwaves that result in sleeplessness.
Another important effect of CBD on sleep lies in its ability to stimulate the production of two fatty acids - monoacyglycerol lipase and amide hydrolase - and their impact in producing non-REM sleep.(8) This secondary response to CBD was similar to the early effects of the CB1 blockade, which fragmented NREM sleep and caused episodes of wakefulness during the REM periods between the deeper NREM cycles.
Administering CBD, which creates a CB1 blockade, had broadband power within the brainwave activity during NREM sleep cycles. These results support the hypothesis that endocannabinoid signaling through CB1 is a necessary component for NREM stability. The observations have a good deal of positive research associated with them in both rodent and primate studies and merit more study with human subjects suffering from sleep deprivation.
So recalling that most sleep deprivation occurs in the REM cycles that punctuate the deeper NREM cycles, it makes sense that modulating the neural activity of CB1 and CB2 receptors to curtail brain activity specifically during REM sleep cycles would have a positive impact on an individual's ability to both achieve and maintain NREM sleep cycles.
While there are most certainly physiological causes underlying sleep disorders, there are also cases where the primary causation can be anxiety, stress or other points of inflammation within the body that make it difficult to fully relax and sleep. CBD has been shown to positively impact these causes of sleep disorders as well in a few different ways. Mental Health Daily, an online research and blog resource for all issues related to mental health, recently dove into the topic of CBD and its effect on stress, anxiety and depression. Here are two key findings: (9)
CB1 + CB2 Receptors - CBD stimulates CB1/CB2 receptor sites to contribute to general anti-inflammatory effects, which are linked to mood disorders. Mental Health Daily cites data that links neuroinflammation to a wide continuum of anxiety disorders. Administering CBD for its anti-inflammatory properties contributes to reduced inflammation throughout the body, including the brain, so it yields positive anxiolytic responses.
Opioid Receptor Modulator (ORM) - This particular neurogenesis reaction relates to the degree of severity to which one feels anxiety or depression. Delta receptor agonists block the anxiogenic effects of stressors. Specifically, modulation of the delta receptors within the central amygdala show that the severity to which an individual experiences neurogenetic responses such as depression, anxiety and stress can be greatly reduced. This occurs by the interaction of CBD with the ORM with the aforementioned 5-HT1A and CB1/CB2 effects. Reducing stress and anxiety can alleviate the "racing mind" that often keeps people up at night, rather than allowing full relaxation leading to sleep.
CBD attacks the widespread problem of sleep deprivation by regulating the functions within the brain that impair healthy sleep. Whether there is a physical cause of sleep deprivation, like chronic pain or inflammation, or a psychological cause like stress or anxiety, CBD works to even out the neurological responses and synaptic interactions that occur during sleep to maximize restorative NREM sleep.
For many who experience sleep disorders, or simply seek a deeper more restorative sleep, CBD provides an option that will lead to a gentle and restorative sleep cycle every night.
