NATIONAL SLEEPY HEAD DAY is celebrated in Finland. Traditionally on this day, the last person in the house (also dubbed as the ‘laziest’) to wake up is woken up using water, either by being thrown into a lake or the sea, or by having water thrown on them. It is based on the story of the Saints of Ephesus who slept in a cave for some 200 years during the Middle Ages whilst hiding from persecution by the Roman Emperor at the time.
