March 15 — World Sleep Day

In 2008, at the initiative of the World Health Organization, it was decided to celebrate Sleep Day every second Friday of a full week in March. In 2019, this date falls on March 15th. Do not be surprised by such an unusual holiday: we spend about one-third of our lives sleeping on average, and the importance of sleep cannot be overestimated. A person who has slept well usually feels energetic and healthy, while if the night was restless, it would be difficult to expect anything good from the coming day. An underslept individual typically shows extreme irritability, reduced work performance, memory, and attention span, experiencing bad mood both in the morning and throughout the entire day [1]. The choice of March as the month for this celebration is no coincidence as many people report feeling tired due to prolonged winter, cold weather, lack of sunlight, muddy streets, and vitamin deficiency. These issues can be effectively addressed through healthy and high-qualit y sleep.
