A visitor reclines at a museum in Wolfsburg, Germany. The museum now allows patrons remain an extra hour once each week, giving them a chance to doze off in front its art collection.

The International Foundation for Mental Health and Neuro-Science launched the day to enhance people's awareness of sleeping problems.
