Sleep and Mental health

You must have heard the phrase “woke up on the wrong side of the bed”, right? Well, it’s not just a phrase. How you sleep and how much sleep you get is very closely related to your psychological and emotional health and is also linked to mental health disorders such as depression, anxiety, bipolar disorder, ADHD, and other conditions.

Poor sleep patterns can also cause sleep disorders like insomnia and sleep apnea. These conditions also play an important role in causing mental health problems.

The Relationship Between Sleep & Mental Health

Relationship Between Sleep & Mental Health

Just like our physical activity is related to our physical rest, emotional activity is related to our psychological rest. The brain is an organ that doesn’t stop working but it too needs to “recharge” at some point. Sleep is needed to help our brain “reset” to be healthy to deal with emotional and mental problems.

At least eight hours of sleep every night, especially REM (Rapid Eye Movement) sleep promotes better brain function. When we are sleeping, our brain is working constantly to evaluate our thoughts and memories. Lack of sleep or sleep deprivation can negatively influence our emotional reactivity. This may lead to an increase in serious mental health disorders including the risk of self-harm.

Sleep & Mental Health Disorders

1. Depression

Depression is a mental health disorder where a person feels extreme bouts of sadness, hopelessness, and even thoughts of self-harm. According to research, people with depression have shown more symptoms of insomnia, daytime sleepiness, and hypersomnia than others. Recently, it has also been recorded that poor sleep can cause or increase symptoms of depression.

2. Seasonal Affective Disorder

Seasonal Affective Disorder

Seasonal Affective Disorder (SAD) is a type of depressive disorder that affects people during a particular season. This disorder disrupts a person’s sleep cycle. People with SAD are more likely to either sleep too much or too little. This disruption of sleep patterns also negatively influences a person’s mental health.

3. Anxiety Disorders

Anxiety Disorders

Anxiety disorders are the most commonly diagnosed disorders around the world. These disorders create situations where a person’s daily life is affected. General anxiety disorder, social anxiety disorder, panic disorder, phobias, OCD, and PTSD are all types of anxiety disorders.

These disorders create worry and fear in a person’s mind which, in turn, is associated with sleep disorders as well. When the mind is in a state of fear and worry, it causes sleep disruptions and poor sleep patterns.

Research has shown that people with PTSD (post-traumatic stress disorder) have more trouble with sleep than others. They are more likely to get frequent nightmares about their trauma and experience a state of alertness.

Poor sleep patterns can increase and worsen anxiety in people even if they show mild signs and symptoms of anxiety disorders.

4. Bipolar Disorder

People with bipolar disorder experience extreme mood swings – manic (high) and depressive (low). These mood swings can have a severe impact on a person’s everyday life. In people with bipolar disorder, their sleep patterns change depending on their emotional state. A person in a manic period may not feel the need to sleep more but during a depressive period, they may sleep more.

Irregular sleep patterns can increase or worsen manic and depressive episodes.

5. ADHD (Attention Deficit Hyperactivity Disorder)

ADHD is a neurodevelopmental disorder that includes a short attention span and immense impulsiveness. This disorder is usually diagnosed in children and may last into adulthood. People and children with ADHD face difficulty in falling asleep and excessive daytime sleepiness. ADHD can also cause restless leg syndrome (RLS).

CBT is effective in treating depression, anxiety disorders, and bipolar disorders, among others. CBT can also help treat insomnia and improve emotional and mental well-being.

2. Lifestyle changes

Improving sleep hygiene is as important as maintaining physical health hygiene. You can improve your sleep patterns by:

1. Establishing and maintaining a regular sleep cycle

2. Incorporating relaxation techniques and breathing exercises before bed

3. Avoiding or limiting the use of alcohol, caffeine, or nicotine before bedtime

4. Avoiding drinking lots of liquid before bed

5. Avoiding going to bed until you feel sleepy or drowsy

O sleep! O gentle sleep!

Nature’s soft nurse, how have I frightened thee!

That thou no more wilt weigh my eyelids down

And steep my senses in forgetfulness?
