Description
Xiaoyu Xiao headed a 2026 sleep study on how night-to-night swings shape how people with chronic insomnia judge their own sleep. Felt sleep often differs from measured sleep in insomnia, and daily ups and downs may drive that gap. Fifty patients tracked sleep at home with devices and diaries for five to seven nights, yielding 312 valid nights for analysis.
Bias was defined as measured sleep minus felt sleep for time asleep, efficiency, and wake time after falling asleep. Felt changes lagged behind real nightly changes, showing muted response to good or bad nights. People with steadier total sleep time showed larger bias in felt duration and efficiency overall. Variability in light sleep share also shaped wake perception.
