A recent study by researchers from the University of York and the University of East Anglia reveals that sleep deprivation significantly affects the brain’s ability to suppress unwanted memories and intrusive thoughts. Published in the Proceedings of the National Academy of Sciences, the study analyzed fMRI scans of 85 participants, finding that those who had adequate sleep could better control negative thoughts than their sleep-deprived counterparts. This research provides insights into the potential links between sleep, mental health, and the development of targeted therapies.
