More time using electronic devices or watching TV among children and young adults was linked with higher cardiometabolic disease risk, including high blood pressure, high cholesterol and insulin resistance, based on data from more than 1,000 participants in Denmark. The association between screen time and cardiometabolic risks was strongest in youth who slept fewer hours, suggesting that screen use may harm health by "stealing" time from sleep, researchers said.

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.
