In my research, I learned that sleep studies play a crucial role in diagnosing Delayed Sleep Phase Syndrome (DSPS). They help identify the disorder by monitoring one's sleep patterns, brain waves, breathing rate, and eye and leg movements. These studies are essential as they differentiate DSPS from other sleep disorders. In most cases, people with DSPS have a delayed internal body clock that causes them to sleep and wake up at later times, which sleep studies can spot. So if you're constantly struggling with a mismatched sleep schedule, a sleep study might be the answer.
