Sleep Deepening Negative Memories: New Study Signals Sleep's Role in Anxiety Among Thai Youth
A recent study suggests that sleep, long seen as restorative, may actually strengthen negative memory biases in anxious children. The finding helps explain why some youths develop persistent worries that spread across school, family, and social settings. In a controlled experiment with 34 participants aged 9-14, children diagnosed with higher anxiety were more likely to falsely recognize new but similar negative images as ones they had seen before, but only after a sleep interval between learning and testing. This points to sleep-dependent memory consolidation reinforcing threatening associations in anxious youth, potentially expanding a single negative experience into broader fears.
