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 categorized 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.

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. Data from the Department of Health of the Hong Kong SAR also revealed that nearly half (48%) of respondents aged 15 and above had experienced sleep disturbances in the past 30 days—including difficulty falling asleep, waking up during the night, or waking early and being unable to return to sleep. These statistics underscore the severity of insomnia in Hong Kong and its impact on daily life.

Insomnia not only affects physical health but can also contribute to cardiovascular disease, emotional disorders, and substance misuse. Therefore, effective treatment and management of insomnia are essential. Experts recommend 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. Psychological therapy and medication can also be effective treatment options.

Overall, insomnia is a significant public health issue in Hong Kong. It calls for collective attention and efforts across society to improve sleep quality and enhance overall well-being for the public.
