"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."
"To use the sleep calculator, you simply need to enter your age range - anything from a few months old to 65 and over (if you're a parent you can try this on behalf of a baby). Age is a crucial bit of data here because the recommended amount of sleep each night largely depends on your age. The sleep calculator also asks you to choose your preferred sleep schedule."
The Sleep Foundation offers a free online sleep calculator that computes an optimal bedtime using only an age range and a preferred wake-or-go-to-bed time. The tool requests no name or email and delivers personalized recommendations based on unique biology and lifestyle preferences to help prevent sleep deprivation. Age selection spans from a few months old to 65 and over because recommended nightly sleep largely depends on age. The calculator returns a primary bedtime and an alternate option with one fewer sleep cycle; for ages 26–35 with an 8am wake time it recommends 10:45pm (9 hours 15 minutes). Sleep quality affects immunity, cardiovascular health, and cognition.
