Are your employees sleeping enough?

More employees sleeping at work is visible evidence that they’re not getting enough sleep at home, but how many hours of sleep should everyone get each night?

As a quick follow up to last week’s post on tired employees, TIME recently revealed the latest numbers on how long we should be sleeping.

Ideal sleep time is between 6.5 and 7.5 hours each night.

Studies show that sleeping more or less than the ideal affects a person’s health and may even contribute to a shortened lifespan. Very short sleep and very long sleep are both associated with major illnesses such as depression, heart disease and obesity.

Scientists don’t know exactly why, but it seems that people who sleep from 6.5 to 7.5 hours a night live longer than those who sleep more or less than the desired amount.
