Summary

Story summary

A study in the Journal of Sleep Research finds that individuals with higher sleep reactivity to stress experience greater disruption.
Researchers tracked 60 university students with varying sleep reactivity levels over two weeks.
Daily stress correlates with increased pre-sleep cognitive arousal, reducing sleep.
High sleep reactivity led to more severe disturbances than lower-reactivity peers.
The study recommends interventions that target pre-sleep cognitive arousal, especially for individuals with high sleep reactivity.
