Participate in our study on Albinism and Sleep!
Some persons with albinism have trouble sleeping, but we do not know yet whether this is related to their albinism.
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.
Most of us have at least once experienced a bad night of sleep. For example because of worries or pain. But some have poor sleep almost every night. Help us solve this by completing online questionnaires every now and then, whenever it suits you. You will get feedback. Data remain anonymous. Everyone can help, not only poor sleepers. Actually people who always sleep well have the secret to good sleep without even realizing it!

Grote slapers
Een Schotse wetenschapper heeft eens slapende walvissen aangetroffen. Tot dan toe werd aangenomen dat walvissen alleen maar met een hersenhelft tegelijk slapen. De andere hersenhelft blijft actief en een oog open, mogelijk omdat de half slapende walvis zo attent kan zijn op gevaren. De Schot ontdekte uit de kust van Chili een groep diep slapende potvissen die met de bek omhoog verticaal in zee dreef. Potvissen slapen overigens maar 7 procent van hun levenstijd en zijn daarmee de zoogdiersoort die de minste slaap nodig heeft - nog minder dan de giraf (8 procent). Veel mensen slapen een derde van hun leven.
