Spring Sleep Day

Spring Sleep Day 春の睡眠の日 is on March 18th annually. It has a twin day in autumn, on September 3rd. The fall date was chosen as a wordplay on 9/3 being read as "gussuri", which is a word for sleep, and the spring date was chosen to coincide with World Sleep Day.

"Spring Sleep Day" promotes awareness of healthy sleep. It highlights spring as an ideal season to review sleep habits, thanks to its mild temperatures and natural rhythms.  It was established by the Sleep Health Promotion Organization in cooperation with the Japanese Society of Sleep Research.
