The CDC calls insufficient sleep a "public health problem." But sleep & circadian rhythms are oft-ignored—even derided--aspects of health.

When you ask subjects about lifestyle, don't stop @ diet/exercise. Ask about sleep. When you ask about sleep, don't stop @ length/quality. Ask about circadian timing: when ppl sleep. Is timing dictated by their body clock *or* work/family demands?

AOU is an unprecedented opp to... more »

Study would seek to characterize the etiological bases, including genetic, socio-cultural and environmental, for the circadian timing, duration and quality of sleep and vulnerability to develop sleep disorders.

There is a need to include survey questions sensitive to sleep and circadian phenotypes, which may be easily administered via smart phone applications.

It would increase the utility of specimens collected in AoU if they were all time stamped, providing general circadian information.

Wearables that can capture sleep and circadian information-across the day/night and over time--should be included. Activity monitors, EEG, ECG and Oximetry measurement are increasingly accessible with miniaturization of technology. Consumer interest in many of these devices has accelerated development and driven costs down. Analysis of these data-perhaps using open-platforms- hold promise for deriving quantitative measurements... more »

Biomarkers of sleep sufficiency need to be developed for use in safety for duty and also for use as longer term health indices.

Chronotype (bedtime and time of arising) is poorly captured in sleep questionnaires. Add activity monitor to track this important metric and relate it to disease endpoints

Sleep participates in regulation of biological systems that support health. Sleep is experienced as restorative; and non-restorative sleep is associated with debilitating fatigue, experienced in many medical conditions. Questions are needed to assess subjective restorative quality of sleep (in the last months) together with questions about mental and physical health, sleep continuity, quality, duration and circadian timing.... more »
