Your genes determine duration of your sleep
Experiencing problems like insomnia or hypersomnia could be genetic, say researchers who identified 76 new gene regions associated with the time a person sleeps.
It is well known that regularly getting adequate sleep — 7 to 8 hours per night — is important for health, and both insufficient sleep — 6 or fewer hours — and excessive sleep — 9 hours or more — have been linked to significant health problems.
Family studies have suggested that 10 to 40 per cent of variation in sleep duration may be inherited, and previous genetic studies have associated variants in two gene regions with the sleep duration.
