What are the recommended noninvasive methods of monitoring rest/sleep cycles. (Select all that applies).

A. Actigraphy: Actigraphy involves wearing a wristwatch-like device that measures movement to estimate sleep-wake patterns over days to weeks. It is noninvasive and widely used for monitoring circadian rhythms and sleep cycles in naturalistic settings. B. Polysomnogram: A polysomnogram is an in-lab sleep study that records brain waves, oxygen levels, heart rate, and other physiological data. While it provides detailed sleep information, it is invasive and requires clinical supervision, so it is not considered a noninvasive monitoring method. C. Multiple Sleep Latency Test: The MSLT measures how quickly a person falls asleep in a controlled environment across several nap opportunities. It is invasive and performed in a lab, making it unsuitable as a noninvasive monitoring tool for daily sleep cycles. D. Inducing sleep with a benzodiazepine: Pharmacologically inducing sleep is an intervention rather than a monitoring method. It does not provide objective data on natural sleep-wake patterns and is not a recommended noninvasive monitoring technique.
