Disturbed sleep patterns refer to any disruptions or irregularities in an individual's normal sleep cycle. This can include a variety of issues such as difficulty falling asleep, waking up frequently throughout the night, experiencing restless sleep, or having trouble staying asleep for long periods of time. These disturbances can be caused by various factors including stress, anxiety, medical conditions, medication side effects, and lifestyle choices. Disturbed sleep patterns are often associated with negative health outcomes such as fatigue, irritability, difficulty concentrating, and an increased risk for chronic diseases like diabetes or cardiovascular disease.
