Experts claim most healthy adults need seven to nine hours per night - but this is hardly exact, and it also depends on age and individual needs. Thankfully, a free online tool now tells if you're getting enough slumber. The sleep calculator, from non-profit organisation the Sleep Foundation, works out your optimum bedtime based on your details. It asks just two questions to ensure a decent amount of shut-eye each time - and it doesn't want your name or email address.

A survey of 2,000 Americans found that the average time people fall asleep is 11.18pm. For those who stayed up later than planned, 29% cited chores, while 21% enjoyed nighttime activities. The average American starts their going-to-bed routine at 10.15pm, taking 21 minutes before being tucked in by 10.36pm, and another 42 minutes to actually fall asleep.
