Insomnia and Mental Health: Breaking the Vicious Cycle

Sleep is one of humanity's most important basic needs, yet also one of the most vulnerable. Stress, worries, anxiety, and depression often first disrupt sleep. And when sleep is disrupted, mental health problems worsen: creating a vicious cycle that can be difficult to break without help.

The Connection Between Insomnia and Mental Health

The relationship between insomnia and mental health problems is bidirectional:

Mental health problems cause insomnia: Anxiety keeps the mind alert at night, depression can cause early morning awakening, and stress makes falling asleep difficult.

Insomnia worsens mental health problems: Sleep deprivation impairs emotion regulation, increases irritability, weakens concentration, and significantly raises the risk of depression and anxiety.

Research shows that chronic insomnia doubles the risk of depression. Conversely, effective treatment of insomnia significantly reduces depressive symptoms.

Different Forms of Insomnia

Insomnia is not a single uniform problem but can manifest in different ways:

• Difficulty falling asleep: When going to bed, the mind starts racing and falling asleep takes more than 30 minutes.
• Night wakings: You wake in the middle of the night and falling back asleep is difficult.
• Early morning awakening: You wake in the early hours and cannot sleep again, despite being tired.
• Non-restorative sleep: You sleep enough hours but wake up tired.

When insomnia occurs at least three nights a week for more than three months, it is classified as chronic insomnia.

Self-Help for Insomnia: Sleep Hygiene

Good sleep hygiene is the foundation of all insomnia treatment:

Regular sleep schedule: Go to bed and wake up at the same time every day: including weekends. This is the single most important factor.

Bed is for sleeping: Do not work, look at your phone, or watch television in bed. The brain should associate the bed with sleep only.

Wind-down routine: Begin your evening routine 1–2 hours before bedtime. Dim lights, avoid screens, and do calming activities.

Avoid caffeine after midday: Coffee's effects can last up to 8 hours.

Exercise: Regular exercise improves sleep quality, but avoid strenuous exercise 3 hours before bedtime.

Bedroom conditions: A cool (18–20 degrees), dark, and quiet bedroom promotes sleep.

Do not force sleep: If you cannot fall asleep within 20 minutes, get up and do something calming. Return to bed only when you feel sleepy.

Cognitive Behavioral Therapy for Insomnia (CBT-I)

CBT-I is the most effective evidence-based treatment for insomnia: even more effective than sleep medication in the long term. It consists of several components:

Sleep restriction: Time spent in bed is initially limited to match actual sleep time. This increases sleep pressure and improves sleep quality.

Stimulus control: The association between bed and sleep is strengthened by only going to bed when sleepy and getting up if sleep does not come.

Cognitive work: Identifying and challenging thoughts that maintain insomnia ("I will never sleep," "tomorrow will be ruined").

Relaxation exercises: Progressive muscle relaxation, breathing exercises, and mindfulness techniques.

CBT-I typically takes 4–8 sessions and produces lasting results.

Sleep Medication: Short-Term Help

Sleep medication can be justified short-term in acute situations, but it does not address the root causes of insomnia. Long-term use can lead to dependence and impair the natural quality of sleep.

If you use sleep medication, discuss with your doctor a plan for reducing it and transitioning to therapy-based treatment.

When to Seek Professional Help for Insomnia

Seek help if:

• Insomnia has continued for more than a month
• Fatigue interferes with work, relationships, or daily functioning
• Insomnia is associated with depression or anxiety
• Sleep medication use is regular
• You have tried self-help methods without results

Therapy Costs and Availability

A CBT-I treatment course typically costs 4–8 sessions at 80–120 euros each. Kela's rehabilitative psychotherapy may cover costs if insomnia is associated with a diagnosed mental health problem.

Where to find a therapist

You can look for a therapist in several places:

• Search services run by the Finnish Psychological Association (Psykologiliitto) and professional bodies.
• Kela's service provider search, if you are applying for rehabilitative psychotherapy (only Kela-approved therapists qualify for reimbursement).
• The Valitse Terapia service and other directories.
• Your own health centre, occupational health service or student health service (YTHS), which can refer you onward.

You can contact several therapists and see with whom the collaboration feels natural.
