Posted on March 17 2017
WORLD SLEEP DAY 2017
This year's World Sleep Day is held on Friday, March 17th
World Sleep Day is an awareness activity of World Sleep Society, which aims to advance knowledge about sleep, circadian rhythms, sleep health, and sleep disorders worldwide, especially in those parts of the world where this knowledge has not advanced sufficiently.
Every year, many different activities are held around the world to spread the word and increase the awareness of sleeping health.
To celebrate this year's World Sleep Day, LANGRIA has compiled for you 25 random, funny facts about sleep:
