If you struggle to get the full eight hours at night your parents could be to blame.
Suffering from sleep problems could be genetic, a new study suggests.
Scientists at the University of Exeter have identified 76 new genes which are associated with sleep duration after examining nearly 500,000 Britons.
While carrying a single gene variant influenced the average amount of sleep by only a minute, participants carrying the largest number of duration-increasing variants reported an average of 22 more minutes of sleep, compared with those with the fewest.
Previous studies have shown that regularly getting adequate sleep – between seven and eight hours per night – is important to health.
