What Causes Stress and Anxiety?

Stress and anxiety can stem from various sources, such as work-related stress, financial concerns, relationship issues, and traumatic experiences. Prolonged exposure to stress can lead to chronic anxiety, which can significantly affect one’s daily life, including their sleep quality.


Acute Stress

Acute stress is a short-term response to a specific event or situation. It can cause temporary sleep disruptions, but once the stressor is resolved, sleep generally returns to normal.

Chronic Stress

Chronic stress, on the other hand, can have long-lasting effects on your sleep. Prolonged exposure to stressors can make it difficult to fall asleep or stay asleep, leading to sleep disorders like insomnia.


Generalised Anxiety Disorder

People with generalised anxiety disorder experience excessive, uncontrollable worry about everyday situations. This constant worry can disrupt sleep, causing difficulty falling asleep, staying asleep, or feeling rested upon waking.

Panic Disorder

Panic disorder is characterised by sudden, intense feelings of terror, often accompanied by physical symptoms. Panic attacks can occur during sleep, causing sufferers to wake up feeling extremely anxious.

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder involves persistent, unwanted thoughts and repetitive behaviours. These thoughts and behaviours can interfere with sleep, causing disruptions and difficulty falling asleep.

Social Anxiety Disorder

Social anxiety disorder involves intense fear of social situations, which can cause sleep disturbances as individuals worry about upcoming events or interactions.

Types of Sleep Disorders Caused by Stress and Anxiety

Stress and anxiety can lead to various sleep disorders, including:-


Insomnia is the most common sleep disorder associated with stress and anxiety. It involves difficulty falling asleep, staying asleep, or waking up too early.

Sleep Apnoea

Sleep apnoea is a disorder in which breathing repeatedly stops and starts during sleep. Although not directly caused by stress or anxiety, they can exacerbate the condition by causing disruptions in sleep patterns.

Restless Legs Syndrome

Restless legs syndrome is a condition where individuals experience an irresistible urge to move their legs, especially at night. While the direct cause is unknown, stress and anxiety have been linked to worsening symptoms.

Circadian Rhythm Sleep Disorders

Circadian rhythm sleep disorders involve disruptions in the body’s internal clock, which can be affected by stress and anxiety. This can lead to difficulty falling asleep, staying asleep, or waking up at appropriate times.


The symptoms of sleep disorders caused by stress and anxiety can vary, but some common ones include:-

  • Difficulty falling asleep
  • Waking up frequently during the night
  • Difficulty staying asleep
  • Waking up too early
  • Feeling tired upon waking
  • Daytime fatigue
  • Irritability or mood swings
  • Difficulty concentrating or focusing


There are various treatment options available for sleep disorders caused by stress and anxiety. These include therapy, medication, and lifestyle changes.

Cognitive Behavioural Therapy

Cognitive behavioural therapy (CBT) is a widely used treatment for anxiety and sleep disorders. CBT helps individuals identify and change negative thought patterns and behaviours that contribute to sleep disturbances.

Sleep Restriction Therapy

Sleep restriction therapy involves limiting the amount of time spent in bed to the actual time spent sleeping. This helps improve sleep efficiency and reset the body’s natural sleep pattern.

Prescription Medication

In some cases, prescription medications like benzodiazepines, non-benzodiazepine hypnotics, or antidepressants may be recommended to help with sleep disorders related to stress and anxiety.

Over-the-counter Sleep Aids

Over-the-counter sleep aids, such as antihistamines, can provide temporary relief for sleep disruptions caused by stress and anxiety. However, they should be used with caution and only as directed, as long-term use can lead to dependence.

Lifestyle Changes


Regular exercise has been proven to help reduce stress, improve mood, and promote better sleep. Aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities on 2 or more days per week.

Relaxation Techniques

Practising relaxation techniques, such as deep breathing, progressive muscle relaxation, or meditation, can help manage stress and anxiety, improving sleep quality.

Sleep Environment Improvements

Creating a sleep-friendly environment is essential for getting quality rest. Keep your bedroom dark, cool, and quiet, and consider using white noise machines or blackout curtains to block out disruptions.
