Abstract

Aim To investigate the effects of the coronavirus disease
2019 (COVID-19) lockdown on sleep habits in the Croatian
general population.
Methods In this cross-sectional study, 1173 respondents
from the general population (809 women) completed
a self-report online questionnaire that gathered demographic data and data on sleep habits and mood changes
before and during the COVID-19 lockdown.
Results During the lockdown, bedtime (from 23:11±1:07
to 23:49±1:32 h, P<0.001) and waketime were delayed
(from 6:51±1:09 to 7:49±1:40 h, P<0.001). Sleep latency
increased from 10 (5-20) to 15 (10-30) minutes (P<0.001).
Bedtime and waketime delays were more pronounced
in women and respondents younger than 30. Compared
with other age groups, respondents younger than 30
more frequently reported insomnia for the first time during the lockdown and had less frequent night-time awakenings (P<0.001), less common problems falling asleep
(P<0.001), less frequently felt calm (P<0.001) and rested
(P<0.001), but more frequently felt sadness (P<0.001) and
fear (P=0.028).
Conclusion The effect of the lockdown on sleep needs
to be better understood. Sleep hygiene education could
serve a first-line lifestyle intervention for people in lockdown experiencing sleep disruption
