Sleep Disorders — Causes, Symptoms and Treatment of Insomnia

Sleep disturbance (insomnia) is one of the most common health problems. Approximately 30% of the adult population report sleep difficulties, and 10% suffer from chronic insomnia.

Sleep quality has a direct impact on mental health, cognitive functioning, the immune system, and overall quality of life. Chronic sleep deprivation increases the risk of depression, anxiety disorders, and other mental health conditions.

Types of sleep disorders

Difficulty falling asleep (initial insomnia) — it takes more than 30 minutes to fall asleep after going to bed. It is often associated with anxiety and overactive thinking.

Sleep fragmentation (middle insomnia) — waking up several times during the night and having difficulty falling back asleep.

Early awakening (terminal insomnia) — waking up at 3–5 a.m. and being unable to fall back asleep. It is often a symptom of depression.

Non-restorative sleep — despite adequate duration, the person wakes up feeling tired.

Causes of insomnia

Mental health conditions

Depression — 75% of patients experience sleep problems

Anxiety disorder — hypervigilance makes it hard to fall asleep

PTSD — Nightmares and Waking Up at Night

Bipolar disorder — during a manic episode, the need for sleep decreases sharply

Lifestyle and environment

Irregular sleep schedule

Using caffeine, nicotine, or alcohol in the evening hours

Using screens before bedtime

Inadequate sleep environment

Lack of physical activity

Insomnia treatment

CBT-I (cognitive-behavioral therapy for insomnia)

CBT-I is the first-line treatment for insomnia. Psychotherapists at GSMRC use:

Sleep restriction therapy — the time spent in bed is matched to the actual time spent sleeping

Stimulus control — using the bed only for sleep

Cognitive restructuring — changing negative beliefs and attitudes about sleep

Relaxation techniques — progressive muscle relaxation, mindfulness

Medication treatment

When CBT-I is not sufficient, a psychiatrist may prescribe:

Melatonin agonists

Orexin receptor antagonists

Low-dose antidepressants — trazodone, mirtazapine

Important: Long-term use of sleeping medications is not recommended. All medications should be taken only as prescribed by a psychiatrist!

Sleep hygiene

Regular schedule: go to bed and wake up at the same time every day

Sleep environment: a dark, quiet, cool room (18–20°C)

Turn off screens: avoid blue light 1 hour before bedtime

Caffeine: have your last cup no later than 14:00

Alcohol: avoid it before bedtime

Exercise: regular, but not within 3 hours before bedtime
