Drug Abuse And Excessive Sleep: Understanding The Connection

Sleep and substance abuse are interconnected, with alterations in one process having consequences for the other. Drugs of abuse and alcohol have disruptive effects on sleep, interfering with the ease of falling asleep, increasing the difficulty of staying asleep, and altering sleep stages. This can result in a cycle of substance use, particularly with stimulants like cocaine, caffeine, and nicotine, which induce wakefulness. Furthermore, substance abuse can cause sleep disturbances, such as insomnia, which can lead to relapse. Sleep impairments associated with drug abuse also contribute to cognitive dysfunction and interfere with memory consolidation and extinction, hindering the learning of non-reinforced drug associations needed for recovery. Recognizing and treating sleep disorders may be crucial for preventing future drug misuse and substance use disorders.

Sleep disorders and drug abuse are interconnected, with one often causing the other

Substance abuse can disrupt sleep latency, duration, and quality. It can lead to nighttime wakefulness, less "good" sleep, lower overall sleep time, and strong daytime sleepiness. Drugs can interfere with the non-rapid eye movement (NREM) stage of sleep, reducing the amount of deep sleep an individual gets. They can also disrupt the rapid eye movement (REM) stage, which is when dreaming occurs and the body moves more.

With chronic substance abuse, sleep disruption becomes more severe, and during abstinence, insomnia is common. Sleep impairments associated with drug abuse can also contribute to cognitive dysfunction in addicted individuals. Additionally, because sleep is important for memory consolidation and the process of extinction, sleep dysfunction might interfere with the learning of non-reinforced drug associations needed for recovery.

Treating sleep disorders may be an important preventive measure against future drug misuse and substance use disorders. Recognizing and addressing sleep issues during substance abuse treatment can also help reduce the risk of relapse.

Drug abuse can cause insomnia and other sleep problems

Substance abuse can cause insomnia and other sleep problems. Sleep problems can be both a cause and an effect of drug abuse. People with sleep disorders may self-medicate with illegal drugs, alcohol, or medication to help them sleep. However, substance misuse or withdrawal from drugs can also cause sleep problems or make them worse.

A study found that 46% of patients with substance abuse issues reported using substances to self-medicate sleep problems. The same study found that 56% of the subjects had insomnia of a moderate to severe degree. Another study found that people in recovery from drug or alcohol abuse were five times more likely to have insomnia.

Substance abuse can lead to nighttime wakefulness, less "good" sleep, lower overall sleep time, and strong daytime sleepiness (hypersomnia). Drugs can change how people go through their sleep stages, affecting the amount of non-rapid eye movement (NREM) sleep they get. NREM is when people get their deep sleep. Drugs can also interfere with rapid eye movement (REM) sleep, where people do their dreaming and move around more.

Drug withdrawal can also cause insomnia and other sleep problems, including broken sleep, strange dreams, or restless leg syndrome. These sleep disturbances can take a toll on people's mental and physical health, making recovery more difficult.

Treating sleep disorders may be an important preventive measure against future drug misuse and substance use disorders.

Sleep problems can increase the risk of drug abuse and relapse

Sleep disturbances can increase the risk of drug abuse and relapse in several ways. Firstly, a lack of sleep can put individuals in a state of "hyperarousal", which can increase the likelihood of drug abuse. Secondly, sleep disturbances can lead to daytime sleepiness, which may drive the use of stimulants such as cocaine, caffeine, and nicotine. Thirdly, sleep problems can be a source of stress, which is a known risk factor for drug abuse. Finally, sleep disturbances can impair cognitive function and make it more difficult to resist drug cravings.

Additionally, sleep disturbances can be both a cause and consequence of drug abuse. For example, alcohol abuse can lead to sleep disturbances, but these disturbances can also increase the risk of alcohol abuse and relapse. This bidirectional relationship between sleep and substance abuse highlights the importance of addressing sleep problems in the treatment of substance use disorders.

Treating sleep disturbances in individuals with substance use disorders can be challenging. While there are pharmacological and behavioural treatments available, more research is needed to determine the most effective approaches. Furthermore, it is important to note that sleep disturbances may be co-occurring with other mental health disorders, such as anxiety and depression, which may also need to be addressed in treatment.

Sleep problems during withdrawal can make recovery harder

Sleep disturbances during withdrawal can be long-lasting. They can be severe enough to reverse the success of drug or alcohol treatment and trigger a relapse into addiction or dependence. The risk of relapse is increased by the fact that sleep problems are common comorbidities of substance abuse.

Substance abuse and sleep problems have a bidirectional relationship. Sleep disturbances can drive drug cravings, impulsivity, and relapse, while drug abuse can cause or worsen sleep issues. This interconnection is due to the neurobiology of sleep and substance abuse, where alterations in one process have consequences for the other.

The impact of sleep problems on recovery is significant. Treating sleep disorders may be an important preventive measure against future drug misuse and substance use disorders. Early diagnosis and treatment of sleep disorders may help reduce relapse rates and improve the chances of sustained remission.

Sleep problems can persist for months or years after quitting drugs

For example, sleep disturbances can continue for 1 to 3 years after achieving sobriety from alcohol. Sleep impairments associated with drug abuse also contribute to cognitive dysfunction in addicted individuals. Furthermore, because sleep is important in memory consolidation and the process of extinction, sleep dysfunction might interfere with the learning of non-reinforced drug associations needed for recovery.

Sleep disturbances can also be a risk factor for substance abuse, and their severity can predict the prognosis of substance use disorders. Sleep disruption results in a cumulation of risk factors that drive drug abuse, including increasing the sensitivity to pain, acting as a stressor, and biasing toward a negative effect.

Recognizing and treating sleep disorders may be an important preventive measure against future drug misuse and substance use disorders.
