The first three hours people spend asleep in bed are often the most effective at restoring mind and body, according to new research. Adrian Williams, professor of Sleep Medicine at King’s College London and the London Sleep Centre, revealed that this is the case regardless of what time an individual gets their shut-eye. A daily eight hour snooze is usually seen as the best dose of sleep. However, sleep expert Dr Neil Stanley begs to differ. He says in the Daily Mail that in reality anything from three to 11 hours a night is normal: “If you feel awake during the day, however much you’re getting is enough”. The message here seems to be, unless the amount of sleep has a negative impact on daily lives, self-diagnosed insomniacs need not worry that they have a problem.
