Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This study is about how sleep loss and being awake at night impacts the ability to think, changes molecules in the blood, and alters the bacteria that live in the gut that typically help keep people healthy. This work will have important implications for the development of treatments and countermeasures for people who do not sleep enough and need to be active at different times of the day and night (e.g., emergency workers and military personnel).
