One of the main consequences of our society’s current schedules is chronic sleep deprivation, which has significant repercussions for our health, a real public health problem. Sleeping less hours than necessary increases the risk of cardiovascular and neurovascular problems, mood disorders, increased risk of work and traffic accidents, decreased work performance and cognitive impairment. A badly asleep society is a less healthy, less productive, less happy, less creative, less empathetic and more aggressive society. Better use of time, with rational schedules that allow the opportunity to get the necessary hours of sleep, is essential to change this situation and achieve a freer and healthier society.
