Insomnia and Addiction | Links, Symptoms & Treatment

Insomnia is a common sleep disorder that makes it hard to fall asleep, stay asleep, or causes early waking without being able to get back to sleep. Even with the chance to sleep, people with insomnia often struggle to get enough rest, leading to daytime fatigue, low energy, mood disturbances and decreased performance at work or school.

In the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), insomnia is classified under Sleep-Wake Disorders and is specifically labelled as ‘Insomnia Disorder,’ distinguishing it from transient or short-term insomnia.

Are there different types of insomnia?

When asked to define insomnia, most people incorrectly state that it’s simply the inability to sleep. However, there are actually many different types of insomnia that a person can experience:

  • Onset insomnia: Difficulty falling asleep at the start of the night, often related to stress, anxiety, or an irregular sleep schedule.
  • Maintenance insomnia: Trouble staying asleep, with frequent waking during the night and difficulty falling back asleep, which can be due to conditions like sleep apnea, chronic pain, or an overactive mind.
  • Behavioural Insomnia of Childhood (BIC): Affects children and involves difficulty falling or staying asleep, often related to poor sleep habits or bedtime resistance.
  • Idiopathic insomnia: A lifelong struggle with insomnia that begins in childhood and continues into adulthood without a clear cause.
  • Paradoxical insomnia: Individuals believe they are experiencing severe insomnia without objective evidence of sleep disturbance, perceiving their sleep as much worse than it is measured to be.

The various types of insomnia highlight the complexity of this disorder and how easily it can be undiagnosed. Each type presents differently, making it challenging to recognise and properly address, often leading to prolonged suffering without proper treatment.

What are the causes of insomnia?

When determining the cause of insomnia, we must first look at the type of insomnia present: acute or chronic.

Acute insomnia is short-term and often triggered by stress or sudden changes in routine, lasting days to weeks. Chronic insomnia, however, is long-term, persisting for months or longer and often linked to underlying health issues or lifestyle factors. Understanding the causes of both can help in managing and treating this common condition.

Causes of acute insomnia

  • Stress and anxiety: Major life events, such as job loss, exams, or relationship issues.
  • Environmental changes: Noise, light, or new sleeping environments.
  • Medical illness: Short-term illness or pain.
  • Medications: Side effects of new or temporary medications.
  • Jet lag or shift work: Disruptions in the body’s internal clock.

Causes of chronic insomnia

  • Chronic stress: Ongoing stress from work, personal life, or financial worries.
  • Mental health disorders: Depression, anxiety and other mood disorders.
  • Medical conditions: Chronic pain, asthma, arthritis, or heart disease.
  • Sleep disorders: Sleep apnea or restless leg syndrome.
  • Substance abuse: Long-term use of alcohol, caffeine, nicotine, or other drugs.
  • Poor sleep habits: Irregular sleep schedules, excessive screen time, or uncomfortable sleeping environments.

Are insomnia and addiction linked?

Insomnia and addiction are often interconnected, with each condition potentially worsening the other. This can lead to increased severity of symptoms for both. When a person has both insomnia and addiction simultaneously, it is referred to as a dual diagnosis or co-occurring disorder. Recognising this link is crucial for effective treatment, as both issues need to be addressed concurrently.

What comes first, insomnia or addiction?

The relationship between insomnia and addiction mirrors the classic chicken and egg dilemma. In cases of co-occurring disorders, it’s often unclear which came first, as each condition can lead to the other. Insomnia can drive individuals to substance use for relief, while addiction can disrupt sleep patterns, leading to insomnia. In the following sections, we take a closer look at both sides of the coin:

Insomnia leading to addiction

Insomnia can often pave the way to addiction, as the struggle to achieve restful sleep drives individuals to seek relief from substances. This phenomenon has been documented well in literature research over the years, with insomnia being identified as a risk factor for a person developing an SUD.

For instance, someone who has difficulty falling asleep might turn to alcohol, thinking a nightcap will help them relax. Initially, it might work, but over time, they may find themselves needing more to get the same effect, leading to dependency.

Similarly, prescription medications like sleeping pills can be a slippery slope. What starts as a legitimate solution can become an addiction if the person begins to misuse the medication, taking higher doses or using it more frequently than prescribed.

Addiction leading to insomnia

Substance abuse alters the brain’s chemistry, disrupting natural sleep cycles. For example, alcohol might initially make a person drowsy, but as it metabolises, it can lead to restless nights and frequent awakenings.

Similarly, the effects of stimulant drugs, such as cocaine, can cause an irregular sleep pattern, making it hard for the brain to maintain a restful state. These disruptions in sleep can perpetuate the cycle of addiction, as individuals may continue using substances in an attempt to find relief from their insomnia, further entrenching their dependency.

In fact, research showed that 66.5% of patients attending addiction rehab experience sleep disturbances, with sleep-maintenance insomnia being the most common type. Different substances impacted the sleep patterns of those in rehab in various ways. For instance, patients with alcohol use disorder and cannabis use disorder often struggle with sleep-onset insomnia, finding it difficult to fall asleep initially.

On the other hand, individuals battling cocaine and heroin use disorders frequently experience sleep-maintenance insomnia, where staying asleep throughout the night becomes a challenge.

How is insomnia and addiction treated at Linwood House?

Overcoming both insomnia and addiction can be challenging, but at Linwood House, we are well-equipped to help you face these issues together. Our approach often begins with a medically monitored detox to safely reduce and eliminate the addictive substance from your system. We understand that this process can sometimes worsen insomnia, so we focus on addressing sleep problems simultaneously.

One of our effective treatments is Cognitive Behavioural Therapy for insomnia (CBT-i). This therapy is comparable to sleep medications in effectiveness but without the associated side effects. CBT-i also offers a lower risk of drug relapse and promotes long-term healthy sleep habits by teaching new skills to improve your natural sleep mechanisms.
