German scientists discovered a gene that may explain why some people can get by with as little as four hours sleep a night, while others need much longer.
More than 4,000 people from seven European countries took part in the project, which involved filling out a questionnaire on their sleeping habits.
Scientists from the Ludwig Maximilians University Munich then analyzed their answers, along with their genes.
They found that those people with two copies of one common variant of the gene ABCC9 slept for a significantly shorter period than those with two copies of the other version.
