Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To test whether baseline levels of slow wave activity (SWA) during sleep are lower in obese adults, and even lower in persons with sleep disordered breathing (SDB) compared to lean adults.

To compare levels of SWA in individuals in relation to their sleep time, blood pressure, heart rate, and markers of glucose metabolism.
