Bad sleeping has negative consequences in terms of personal efficiency and quality of life , besides being potentially associated with diseases. In the week that marks the World Sleep Day (March 14), several units within Hospital da Luz network will offer free screenings to assess possible alterations and disturbances of sleep , namely insomnia and snoring, and to divulge information on this topic. The screenings will be ensured by the clinical teams of the hospital or clinic of choice and will take place between the 11 and 14 March. Consult the list of units, dates, and schedules below. The latest scientific knowledge indicates that there is a correlation between sleep disorders and certain diseases. The most common is obstructive sleep apnea, a respiratory disease that does not choose ages and may entail severe cardiovascular diseases. Some symptoms are more frequent - namely snoring, choking episodes during sleep, waking up tired and feeling sleepy during the day. But less specific complaints, such as fatigue, difficulty concentrating, memory disturbances, insomnia, or mood disorders, may be related with obstructive sleep apnea. Knowing the signs that could raise the suspicion of sleep apnea, being alert and not underestimating it enables you to seek specialized medical care in time and get efficient responses concerning the diagnosis and treatment of sleep apnea. The World Sleep Day was created in 2008 by the north American organization World Sleep Society and is celebrated on the Friday before the spring equinox. In 2025, the theme is “Make sleep health a priority” . Remember: sleeping well promotes a healthy life. If you feel that your sleep is poor, take the screening.
