Help us make a difference of night and day for poor sleepers
Everyone has an occasional bad night's sleep. Because of worries, pain or just because. But many people sleep badly every night. Help us to tackle this by filling out a questionnaire via the Internet every now and then, when it suits you.

Geschiedenis van Slaap 16
De verschillende stadia van slapen, dromen en gewoon slapen, werden door de oude Grieken al erkend. In 1868, rapporteerde William Griesinger dat de ogen in bepaalde stadia van de slaap bewogen. Ook Sigmund Freud merkte lichaamsveranderingen op tijdens bepaalde stadia: in bepaalde stadia verlammen een heleboel spieren. We weten nu dat zowel deze snelle oogbewegingen (Rapid Eye Movements) als de spierverslapping bij een en hetzelfde stadium van slaap horen. Dit stadium is vernoemd naar de oogbewegingen: REM slaap.
