The World Sleep Society designated March 17 as World Sleep Day in 2023. The Faculty of Medicine of the Chinese University of Hong Kong (CUHK) and a research team comprising representatives from 16 countries or regions found that people who habitually sleep for a shorter period have about twice the risk of developing long COVID and are at increased risk for a variety of cardiovascular diseases, compared to those who get enough sleep.
The study showed that double-vaccinated people had nearly twice the risk of developing long COVID when sleep-deprived.
