Insomnia is a sleep disorder characterised by difficulty falling asleep, staying asleep, or obtaining restful sleep. Chronic sleep deprivation refers to consistently not getting enough sleep over an extended period.
Both lead to fatigue, poor concentration, mood problems, and health risks such as weakened immunity or cardiovascular issues. Causes range from stress to lifestyle habits, medical conditions, or mental health disorders.
Treatment may include sleep hygiene practices, therapy (like CBT for insomnia), and medical support.
