Mental health and sleep both terms are both intertwined. When you face sleep deprivation it directly affects your mental state. The statement becomes more apparent by reviewing the question of how does sleep affect your mental health conditions.

Attention-deficit/hyperactivity disorder (ADHD)

It is a neurodevelopmental disorder that includes increased impulsiveness and reduced attention span. Attention deficit/hyperactivity disorder is more common in children. However, in some cases, the disorder lasts into adulthood and even can diagnosed in individuals who are already adults. People going through ADHD commonly have sleeping issues.

Attention-deficit/hyperactivity disorder (ADHD)

They might develop:

  • Difficulty in frequent awakenings
  • Excessive daytime sleepiness
  • Difficulty falling asleep
  • RLS (restless leg syndrome)
  • Obstructive sleep apnea


More than 300 million people around the globe have depression – a common type of mood disorder. Around 75 percent of people with depression show the signs and symptoms of insomnia. Some people also suffer from hypersomnia and excessive daytime sleepiness.

Sleeping problems previously were seen as an outcome of depression. However, growing evidence indicates that sleep deprivation may exacerbate or induce depression. Sleeping problems and depression share a bidirectional relationship and their symptoms are reinforced mutually. Poor sleep can worsen depression and constant depression can lead to lack of sleep.

Seasonal Affective Disorder

It is one of the common subtypes of depression. Seasonal affective disorder often occurs during the times of the year when there are reduced daylight hours. People living in northern areas are more at risk of experiencing this disorder in the winter and fall seasons.

Similarly, if a person is already going through post-traumatic disorder, the condition can affect their regular sleeping pattern.

Anxiety Disorders

The relationship between anxiety and sleep can appear in both directions – similar to numerous other psychological conditions. sleep deprivation can cause feelings of anxiety, but people going through anxiety can also experience sleep deprivation. This interlink can also become a cycle that perpetuates anxiety issues and sleep.

Sleeping issues can act as risk factors for developing and maintaining anxiety disorders.

Likewise, people going through anxiety are more at risk of developing sleeping problems if the condition is left untreated or gets prolonged.
