Adherence
COVID-19 lockdown measures significantly worsened sleep quality in nursing students, primarily through increased sleep latency and reduced sleep efficiency, despite an increase in total time spent in bed.
If you are struggling with sleep during periods of restricted routine (like lockdowns or remote work), do not assume that staying in bed longer will help. The study shows that sleep quality often worsens despite increased time in bed due to delayed bedtimes and increased pre-sleep screen use. Focus on maintaining a consistent sleep-wake schedule and limiting digital device use before bed to improve sleep efficiency.
The main conclusion is that although students spent more time in bed, overall sleep quality was worse during lockdown, as well as being worse in five of the seven components.
Why this rating
Longitudinal observational study with a reasonable sample size (n=207) and statistical significance, but relies on self-reported data (PSQI) rather than objective measures like actigraphy.
