What You'll Learn
Insomnia is a common sleep disorder
Roughly one-third of adults worldwide experience insomnia symptoms, with about 10% of adults meeting the criteria for insomnia disorder, also known as chronic insomnia. This form of insomnia is long-term and persists for a month or longer. While the cause of primary chronic insomnia is not well understood, it is often associated with long-lasting stress, emotional upset, travel, and shift work. Secondary insomnia, on the other hand, is a symptom or side effect of another problem, such as certain medical conditions, medications, or other sleep disorders. Substances like caffeine, tobacco, and alcohol can also contribute to insomnia.
The effects of insomnia can be detrimental, impacting various aspects of an individual's life. Daytime impairments linked to insomnia include sleepiness, fatigue, impaired memory and concentration, irritability, and mood disruptions such as anxiety and depression. These symptoms can interfere with daily activities, work, social life, and hobbies. Moreover, chronic insomnia can have severe health implications, increasing the risk of high blood pressure, coronary heart disease, diabetes, and cancer.
Treating insomnia typically involves a combination of lifestyle changes, sleep hygiene practices, cognitive-behavioural therapy (CBT), and medications. Lifestyle modifications include addressing sleep habits and reducing the consumption of substances like caffeine and alcohol. CBT can help manage anxiety related to sleep issues and establish healthier sleep patterns. While medications can promote sleep, they should be used cautiously due to potential side effects and interactions. It is important to consult a healthcare provider for a proper diagnosis and personalised treatment plan.

Types: acute (short-term) or chronic (long-term)
Insomnia is a sleep disorder characterised by difficulty falling asleep, staying asleep, or both. It can cause daytime impairments such as sleepiness, fatigue, impaired memory, and irritability. Insomnia can be acute (short-term) or chronic (long-term). Acute insomnia is common and is usually caused by stress at work, family pressures, or a traumatic event. It typically lasts for days or weeks.
Chronic insomnia, on the other hand, lasts for a month or longer. It can be primary, where it is not caused by another condition, or secondary, where it is a symptom or side effect of another problem. Secondary insomnia is more common and can be caused by certain medical conditions, medications, other sleep disorders, or substances such as caffeine, tobacco, and alcohol. Chronic insomnia can increase the risk of developing high blood pressure, coronary heart disease, diabetes, and cancer. It can also cause daytime sleepiness, lack of energy, anxiety, depression, and irritability.
The treatment for insomnia depends on its type and severity. Acute insomnia can often be relieved by making lifestyle changes and developing good sleep habits. Cognitive-behavioural therapy (CBT) can also be helpful in relieving the anxiety associated with acute insomnia and improving sleep habits. For chronic insomnia, CBT is considered the most effective initial treatment. If CBT is ineffective or symptoms are severe, medication may be recommended. However, medication should be used cautiously as it can have side effects such as daytime drowsiness and may negatively affect the sleep cycle.
It is important to note that insomnia is a common sleep disorder that can affect anyone, but it is more prevalent in women and older adults. If you are experiencing insomnia, it is advisable to consult a healthcare professional for a proper diagnosis and treatment plan. They may recommend lifestyle changes, CBT, medication, or a combination of these approaches.

Causes: stress, family pressures, shift work, etc
Insomnia is a persistent difficulty with sleep onset, maintenance, consolidation, or overall quality. It occurs despite having a comfortable place to sleep and adequate time for sleep. People with insomnia experience excessive daytime sleepiness, fatigue, and irritability, among other impairments.
Stress
Stress and insomnia are closely linked. Sudden stressors, such as significant changes to one's sleep environment, can trigger short-term insomnia. For example, new parents sharing their bedroom with their baby may experience insomnia symptoms, even if the child is not disruptive. Acute stress can also be caused by visiting or moving to a new location. Persistent stressors, on the other hand, can contribute to chronic insomnia. Once chronic insomnia develops, individuals may experience increased anxiety about sleep, exacerbating insomnia symptoms and leading to a cycle of stress and insomnia.
Family Pressures
While not explicitly mentioned, family pressures can undoubtedly contribute to stress, which, as discussed, is a significant factor in insomnia. Additionally, specific family-related sleep disorders, such as Fatal Familial Insomnia (FFI), can run in families and cause insomnia. FFI is a rare genetic condition that affects the brain and central nervous system, causing progressive insomnia, memory loss, and other severe symptoms. It is caused by a mutation in the PRNP gene, which results in misfolded proteins accumulating in the thalamus, the brain region regulating sleep.
Shift Work
Shift work, specifically non-traditional work hours outside the standard 9 a.m. to 5 p.m. workday, can disrupt the body's natural circadian rhythm and lead to Shift Work Sleep Disorder (SWSD). This disorder causes difficulties adjusting to a different sleep/wake schedule, resulting in issues with falling asleep, staying asleep, and unwanted sleepiness. The impact of SWSD on insomnia can vary depending on the timing of shifts. For example, those working early morning shifts may struggle to fall asleep, while those working evening shifts might have trouble staying asleep. SWSD is treatable with lifestyle changes, light therapy, and/or medication.

Symptoms: daytime sleepiness, lack of energy, anxiety, etc
Insomnia is a common sleep disorder characterised by difficulty falling or staying asleep. While it is usually not dangerous, insomnia can have a significant impact on daily life, affecting energy levels and causing daytime sleepiness.
People with insomnia may experience frequent sleep deprivation, resulting in a constant sense of fatigue and exhaustion. This can lead to increased anxiety, as the body's 'fight or flight' response is activated. The anxiety-insomnia cycle can be challenging to break, as worries and negative thought patterns further disrupt sleep, causing insomnia to persist.
Daytime sleepiness is a significant concern for individuals with insomnia, particularly when performing tasks that require alertness and attention, such as driving. Sleep deprivation resulting from insomnia can also increase the risk of developing various health conditions, including depression, high blood pressure, heart attack, and type 2 diabetes.
In addition to daytime sleepiness and fatigue, individuals with insomnia may experience anxiety, worry, and a constant sense of dread or apprehension. They may find themselves ruminating, or thinking deeply about their worries, which can make it difficult to relax and unwind before sleep. Breaking the cycle of negative thoughts can be challenging, but techniques such as focusing on something relaxing or distracting, like soothing music or reading a book, can help to calm anxiety and improve sleep. Maintaining a consistent sleep schedule and preparing for the next day in advance can also reduce anxiety and improve sleep habits.
Treating insomnia often involves a combination of lifestyle changes, developing good sleep habits, and sometimes medication. Sleep specialists can provide guidance and recommend various approaches to improve sleep quality and overall wellbeing.

Treatment: CBT, lifestyle changes, medication, etc
Insomnia is typically treatable and there are many ways to manage it. The main approaches are:
Cognitive Behavioural Therapy (CBT)
Also known as CBT-I, this is recommended by the AASM as a first-line treatment for chronic insomnia in adults. CBT-I can be delivered in person, either individually or in groups, or via telehealth. When access to CBT-I is limited, digital CBT-I (dCBT-I) through websites and apps can be followed by therapist-delivered CBT-I. Evidence-based dCBT-I programs employ combinations of sleep hygiene, sleep restriction, stimulus control, relaxation therapy/mindfulness, and cognitive therapy over several weeks. Some dCBT-I treatments are marketed directly to consumers and include relaxation apps and devices, interactive mindfulness activities, and sleep enhancers such as wearables.
Lifestyle Changes
Developing and practicing good sleep habits, also known as sleep hygiene, can help treat insomnia. This may include natural changes in sleep needs, as an infant needs significantly more sleep than an adult.
Medication
Many different types of medications can help with insomnia, including sedative or hypnotic drugs, both prescription and nonprescription, as well as mental health medications, and certain herbs and supplements. Your healthcare provider is the best person to recommend possible treatments.
