Delayed Sleep

Phase Syndrome Delayed Sleep Phase Syndrome (DSPS) is a disorder in which a person's circadian rhythm is out of sync with their environment. It is characterized by a person's natural sleep-wake cycle (circadian rhythm) being delayed by two or more hours each day, resulting in difficulty falling asleep at a desired time, as well as difficulty waking up in the morning. DSPS can significantly affect mental and physical health, quality of life, and productivity. It is most commonly treated through behavioral therapy, light therapy, and medications that can help regulate and normalize sleep. Knowledge and recognition of DSPS is important to help those affected receive proper treatment and improve their quality of life.
