Insomnia & CBT-I (Cognitive Behavioral Therapy for Insomnia)
What is it?
Insomnia means you have trouble falling asleep, staying asleep, or waking up too early and not being able to go back to sleep.
To be considered a sleep disorder, these problems must happen at least 3 nights per week for at least 3 months and cause daytime problems like fatigue, poor concentration, or mood changes. Insomnia is one of the most common sleep disorders, affecting about 6–10% of adults.
How is it diagnosed?
Insomnia is diagnosed based on your description of your sleep problems — no special tests are usually needed. Your doctor will ask about your sleep habits, daily routine, medical history, and any medications you take. You may be asked to keep a sleep diary for 1–2 weeks. A sleep study (polysomnography) is generally not needed for insomnia unless your doctor suspects another sleep disorder.

The recommended first-line treatment is Cognitive Behavioral Therapy for Insomnia (CBT-I) — not sleeping pills. CBT-I is a structured program, usually 4–8 sessions, that helps you change the habits and thought patterns that keep you from sleeping well. It includes:
-
Sleep restriction: Limiting time in bed to match the amount you actually sleep, then gradually increasing it.
-
Stimulus control: Strengthening the connection between your bed and sleep (e.g., only go to bed when sleepy, get out of bed if you can't sleep).
-
Relaxation techniques: Methods to calm your mind and body before bed.
-
Cognitive therapy: Addressing worries and unrealistic expectations about sleep.
-
Sleep hygiene education: Practical tips like keeping a consistent schedule, limiting caffeine, and creating a comfortable sleep environment.
CBT-I can be delivered in person, by telehealth, or through digital apps. Medications may be considered in some cases, but CBT-I has longer-lasting benefits.

A: Sleep medications can help in the short term, but they are not recommended as the first or only treatment. CBT-I is preferred because it addresses the root causes of insomnia without the side effects or dependency risks of medications.
