Editorial: Long-term effects of COVID-19 pandemic on sleep and their relationships with mental health.

SARS-CoV-2 spread posed unprecedented challenges to modern societies, pervasively reshaping the daily life of everyone. The lockdown periods and the subsequent restraining measures deeply impacted the sleep and mental health of the worldwide population (AlRasheed et al., 2022;Sousa et al., 2021), with effects that persisted in the long run (Salfi et al., 2021;Conte et al., 2021). The stressful experience of SARS-CoV-2 infection and hospitalization has been associated with alarming rates of post-traumatic symptoms among COVID-19 survivors (Nagarajan et al., 2022). Moreover, social distancing drove a large-scale transition to a new working approach named remote working, inevitably affecting people's sleep quality and habits (Salfi et al., 2022, Massar et al., 2022). The studies collected in the present Research Topic, each distinct in its focus, converge to offer a holistic understanding of the pandemic impact on sleep, mental well-being, and their intricate interplay.
