insomnia (symptom)

Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or waking up too early, resulting in poor-quality rest. It can cause feeling tired, irritable, and unable to focus during the day. Insomnia can be caused by stress, anxiety, medical conditions, medications, or poor sleep habits. It may be short-term (acute) or long-lasting (chronic). Managing insomnia often involves addressing underlying causes, improving sleep environment, and adopting healthy sleep routines. Persistent insomnia can negatively impact overall health and daily functioning, so seeking medical advice is recommended if it persists.
