Sleep health improvement trajectories after a pandemic: insights from a national health survey

Sleep health improvement post-pandemic was uneven across sleep dimensions and population subgroups. Behavioural sleep dimensions improved earlier, while subjective satisfaction lagged. Socioeconomic factors, particularly material deprivation, were strongly associated with poorer and slower improvements. These findings highlight the importance of incorporating sleep health into pandemic preparedness and tailoring interventions to address both behavioural and structural determinants of health.
