Which doctor treats insomnia?

For insomnia, a general physician is often the appropriate starting point. They can examine you, order relevant tests, and refer to another specialist if needed. View available doctors.

How doctors generally evaluate this problem

Doctors review sleep habits, caffeine and screen use, stress, mood symptoms, and medicines. They may screen for depression, anxiety, sleep apnoea, or restless legs before recommending treatment.

General treatment and management

Sleep hygiene — consistent schedule, dark quiet bedroom, limiting screens before bed — helps many people. Cognitive behavioural therapy for insomnia (CBT-I) and short-term medicines may be prescribed when appropriate. Avoid long-term use of sedatives without medical supervision.

Prevention and lifestyle

Keep a regular sleep schedule, limit caffeine after midday, exercise regularly but not immediately before bed, and address stress and mood problems early with professional support.
