A new sleep calculator has been launched which will tell you the optimum time to go to bed based on when you need to get up.
You may assume that the longer you sleep the more rested you’ll be but this calculator disputes this. Instead, it calculates when you should go to bed according to when you need to get up by assessing the body’s natural sleep rhythm. Therefore, it may tell you to get less hours sleep than you’re currently getting to wake up more rested – confusing right?
The Sleep Calculator website states: “Getting a good night’s sleep is about more than simply going to bed early – it’s about waking up at the right time too.”
“Using a formula based on the body’s natural rhythms, the Sleep Calculator will work out the best time for you to rise or go to sleep.”
The calculator works on the principle that everyone sleeps in about five or six cycles which last roughly 90 minutes. It takes into consideration that on average it takes 14 minutes to fall asleep after getting into bed.
Waking up midway through a cycle can leave you feeling tired and grouchy the next day. The idea is to wake up in between cycles and feel refreshed in the morning.
So, according to the new calculator, here are the times to hit the hay depending on when you need to get up…
If you need to get up at 7am…
You need to go to bed at either 9.46pm or 11.16pm. If you won’t make these times, then 12.46am and 2.16am will also work.
If you need to get up at 8am…
You need to get into bed at 10.46pm, 12.16am, 1.46am or 3.16am.
If you need to get up at 6am…
You need to go to bed at either 8.46pm, 10.16pm or even 11.46pm or if you’re out late then 1.16am.
Try it tonight and see if you wake up feeling bionic tomorrow. We’ll be doing the same.
