Summary

This study looked at how race-based social rejection impacts sleep and nighttime heart function. About 139 African American and Caucasian adults spent two nights in a sleep lab—one after a rejection task and one after a neutral task. Researchers measured how quickly they fell asleep and how well they slept using brain-wave monitoring.
