Effect of lockdown on sleep-wake rhythm and alcohol use.

The global covid-19 pandemic has imposed radical changes in daily lives. This study reflects upon sociodemographic and clinical characteristics (sleep-wake rhythm, psychiatric symptoms, and alcohol use behavior) during the full lockdown, comparing individuals who increased their alcohol use (iAU), those who maintained a stable use (sAU), and those who did not consume alcohol (AnoU). Participants were recruited via e-mails and they were required to complete an online survey that included questionnaires, during the last week of the full lockdown.

No further delays in offering booster doses in countries experiencing a major resurgence of COVID-19.

Covid booster shots should be proposed and recommended to all fully vaccinated individuals, considering antibody levels are waning over time and that the risk of being infected typically reappears after 6 months.
