On the World Day of Sleep, celebrated on March 15, Hospital da Luz Setúbal will offer free screening to the population in general, to evaluate eventual sleep alterations and disorders, such as insomnia and snoring. All those interested should go to Floor 0, between 9:00 a.m. and 18:00 p.m. The World Sleep Day is an initiative of the World Sleep Society, an international organization gathering researchers, health professionals and patients interested in this topic. In 2019, the slogan is “Healthy sleep, healthy ageing”. Sleep deprivation can drastically alter judgement and behaviour, and the latest scientific research indicates a relationship between diseases and sleep disorders – one of the most common being the sleep obstructive apnea, a respiratory disease that can cause serious cardiovascular complications. Remember: sleeping well and sufficiently is one of the rules to be in good health. Please, participate and do the screening.
