Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Both light and exercise are effective countermeasures for space and ground-based crews for circadian phase resetting and alertness levels. The investigators propose to test the combined effects of these two countermeasures to determine whether adding exercise to light stimuli will further improve circadian phase resetting and alertness.
