Researchers highlight challenges in measuring sleep quality and its health impact

Sleep quality is increasingly recognized as crucial for health, but measuring it remains challenging. Researchers note that definitions of sleep quality vary among individuals, complicating assessments. A good night's sleep involves multiple cycles of brain activity. Disruptions to these cycles can lead to various health issues, including cardiovascular disease and diabetes. Currently, sleep is often analyzed using methods like electroencephalograms (EEG) to monitor brain activity or actigraphy to track movement during sleep. These methods help researchers understand sleep quality better.
