Sleep is closely connected to our mental health. While insomnia can be a symptom of mental illness, it is now recognised that sleep problems can also contribute to the onset and worsening of mental health problems, including depression, anxiety, and even suicidal ideation. A sudden dramatic decrease in sleep which is accompanied by an increase in energy, or the lack of need for sleep may be a sign of mania.

What You'll Learn
Insomnia and depression
Sleep is important for a number of brain and body functions, including the processing of daily events and the regulation of emotions and behaviours. Sleep helps maintain cognitive skills, such as attention, learning and memory. Poor sleep can make it much more difficult to cope with even relatively minor stressors and can even impact our ability to perceive the world accurately.
Insomnia is often a symptom of psychiatric disorders, like anxiety and depression. It is now recognised that sleep problems can also contribute to the onset and worsening of different mental health problems, including depression, anxiety and even suicidal ideation. A sudden dramatic decrease in sleep which is accompanied by an increase in energy, or a lack of need for sleep, may be a sign of mania.
Approximately 50% of insomnia cases are related to depression, anxiety or psychological stress. Early morning wakefulness can be a sign of depression, along with low energy, inability to concentrate, sadness and a change in appetite or weight.
Depression can make it harder to sleep, which causes sleep deprivation, which then makes you feel even more depressed. This can set up a cycle that reinforces itself as it gets worse. Mental health issues that can affect sleep include, but aren’t limited to, bipolar disorder, panic disorder, post-traumatic stress disorder (PTSD) and somniphobia (fear of sleep).
Cognitive behavioural therapy for insomnia (CBT-I) has a proven track record in reducing sleeping problems. A large clinical trial also showed that CBT-I could reduce symptoms of many mental health conditions, improving emotional well-being and decreasing psychotic episodes.

Mania and bipolar disorder
Sleep and mental health are closely connected. While insomnia is often associated with depression, anxiety, and psychological stress, a dramatic decrease in sleep, accompanied by an increase in energy, may be a sign of mania. Mania is a symptom of bipolar disorder. Bipolar disorder is characterised by periods of mania and periods of depression.
Mania is a state of elevated mood, energy, and activity levels. During a manic episode, a person may experience an increase in energy, a decreased need for sleep, and a heightened sense of self-confidence. They may also engage in impulsive behaviours and have racing thoughts. Mania can lead to impaired judgement and risky decision-making.
Bipolar disorder is a mental health condition characterised by extreme mood swings. These mood swings can range from the highs of mania to the lows of depression. During a manic phase, a person may feel euphoric, have an inflated sense of self-esteem, and exhibit increased energy and activity levels. They may talk rapidly, have racing thoughts, and engage in risky behaviours. On the other hand, during a depressive phase, a person may experience feelings of sadness, hopelessness, and a loss of interest in activities they once enjoyed. They may also have difficulty sleeping, changes in appetite, and low energy.
The connection between bipolar disorder and sleep disturbances is well-established. Sleep problems can both trigger and worsen bipolar episodes. During a manic episode, a person may experience decreased sleep due to their heightened energy and activity levels. They may feel like they don't need as much sleep as usual or may have trouble falling asleep due to their racing thoughts. On the other hand, during a depressive episode, a person may struggle with insomnia, early morning wakefulness, or hypersomnia (excessive daytime sleepiness).
It is important to note that while a decrease in sleep may be a symptom of mania and bipolar disorder, it can also be a symptom of other mental health conditions or physical illnesses. Therefore, it is crucial to consider the presence of other symptoms and seek professional help for an accurate diagnosis and appropriate treatment.

Anxiety disorders
Sleep deprivation is highly co-morbid with mental health disorders such as anxiety. Many anxiety disorders are associated with difficulties sleeping. Insomnia can be a symptom of anxiety, and sleep problems can contribute to the onset and worsening of anxiety disorders.
People with GAD experience excessive and uncontrollable worry about a variety of things in their life, such as health, work, or relationships. They may find it difficult to control their worry and may feel restless, easily fatigued, or have difficulty concentrating.
Panic disorder is characterised by recurrent and unexpected panic attacks. Panic attacks are sudden periods of intense fear or discomfort, along with various physical symptoms such as a racing heart, sweating, trembling, and shortness of breath. People with panic disorder may live in fear of the next panic attack and may make significant changes to their behaviour to avoid triggers.
Social anxiety disorder involves a significant fear of social or performance situations where one expects to feel embarrassed, judged, rejected, or fearful of offending others. People with this disorder may worry about acting in a way that will be humiliating or embarrassing, and they may avoid social situations or endure them with intense fear or anxiety.
Specific phobias are characterised by a marked fear or anxiety about a specific object or situation, such as heights, enclosed spaces, flying, insects, or animals. The fear is out of proportion to the actual danger posed and can lead to avoidance of the object or situation, or enduring it with intense fear.
Separation anxiety disorder involves excessive fear or anxiety regarding separation from those to whom one is attached, such as a parent or caregiver. It can cause significant distress and impairment in daily life, and it may lead to avoidance of activities or places that trigger separation anxiety.
Treatment for anxiety disorders often involves psychotherapy, such as cognitive-behavioural therapy (CBT), which can help individuals manage their anxiety and improve their sleep. Medications may also be prescribed in some cases. Additionally, improving sleep hygiene and cultivating habits and a bedroom setting conducive to sleep can help reduce sleep disruptions associated with anxiety disorders.

Panic disorder
Insomnia is often related to depression, anxiety, and psychological stress. Early morning wakefulness can be a sign of depression, while a sudden dramatic decrease in sleep may be a sign of mania.
The exact cause of panic disorder is not fully understood, however, there are a number of factors linked to the disorder. These include stressful or traumatic life events, having close family members with the disorder, and an imbalance of neurotransmitters. Panic disorder is more common in women than in men and often starts in the late teens or early adulthood.
People with panic disorder may start to avoid certain situations because they fear they will trigger another attack. This can lead to a cycle of anxiety and panic that reinforces itself and affects quality of life. If left untreated, panic disorder can lead to other health conditions, including depression and substance use disorders.
Cognitive-behavioural therapy (CBT) is a common treatment for panic disorder. It can help to reduce symptoms and improve emotional well-being. Additionally, stepping up sleep hygiene by cultivating habits and a bedroom setting that are conducive to sleep can help to reduce sleep disruptions associated with panic disorder.

Post-traumatic stress disorder (PTSD)
Sleep is closely connected to emotional regulation and mental health. Sleep deprivation can increase the risk of mental health disorders, and insomnia can be a symptom of psychiatric disorders. Mental health issues that can affect sleep include depression, anxiety, bipolar disorder, panic disorder, post-traumatic stress disorder (PTSD), somniphobia (fear of sleep), and mania.
Symptoms of PTSD can include nightmares, flashbacks, avoidance of reminders of the event, negative changes in beliefs and feelings, and hyperarousal (increased arousal, irritability, angry outbursts, self-destructive behaviour, reckless behaviour, hypervigilance, and exaggerated startle response). Sleep disturbances are common in people with PTSD, and these can include insomnia, nightmares, and other sleep problems.
PTSD is often treated with psychotherapy, such as cognitive-behavioural therapy (CBT), and/or medication. CBT for PTSD typically involves exposure therapy, cognitive restructuring, and skills training. Medications such as selective serotonin reuptake inhibitors (SSRIs) and other antidepressants may be prescribed to help manage symptoms.
If you think you may have PTSD, it is important to seek professional help. Treatment can help you manage your symptoms and improve your quality of life.
