Insomnia is one of the most common sleep disorders in Hong Kong and worldwide. According to the World Health Organization (WHO), approximately one in three adults worldwide has experienced insomnia at some point in their lives. Local research shows that around 10–15% of adults in Hong Kong suffer from chronic insomnia. Insomnia is a common sleep disorder in which individuals struggle to fall asleep, stay asleep, or wake up too early — resulting in daytime fatigue, poor concentration, and emotional instability.
Insomnia can be categorised as short-term or long-term: short-term insomnia is often triggered by stress, life changes, or environmental factors, while long-term insomnia may be associated with chronic illnesses or mental health conditions. If left untreated, insomnia can significantly increase the risk of depression, anxiety disorders, and cardiovascular disease.
In Hong Kong, insomnia is a widespread issue. According to a study by The Chinese University of Hong Kong, nearly 70% of people in the city reported experiencing insomnia in the past six months, with work and academic pressure being the main contributors.
The most effective treatment for insomnia is Cognitive Behavioural Therapy for Insomnia (CBT-I), an internationally recognised gold-standard approach that helps patients address unhelpful thoughts and habits around sleep. Medication may also be used as a short-term aid, and should always be prescribed and supervised by a doctor. Developing healthy sleep habits — such as maintaining a regular sleep schedule, creating a quiet and comfortable sleep environment, and avoiding non-sleep activities in bed — is equally important.
Overall, insomnia is a significant public health issue in Hong Kong. If you or someone you know has been struggling with sleep for two weeks or more, and it is affecting daily life, it is advisable to seek professional assessment from a psychiatrist as soon as possible.
