Time to go to Sleep

Adapted from dailymirror

Do you ever go to bed ridiculously early because you need to wake up on time for work - then feel even more tired in the morning?

Well, you might be doing it wrong.

Don't just think that by getting more hours of sleep, you'll be more refreshed in the office the next day. Apparently it's a bit more complicated than that.

But, luckily for us, someone has created a 'sleep calculator', being used on blinds company site web-blinds.com, so we can work out when we need to hit the sack in the click of a button.

Apparently it has more to do with sleep cycles rather than getting more hours of sleep. If you wake up at the wrong time during a sleep cycle, you'll find yourself more tired - even if you were asleep for longer.

Need to make sure you're awake and getting out of bed at 7am? Then you need to go to bed at either 9.46pm or 11.16pm.

If you're having a late night and you don't fancy either of these, then 12.46am and 2.16am will also work.

The sleep calculator works with the average of 14 minutes it takes people to naturally fall asleep, so you don't necessarily need to be in bed by this time.

Don't need to get up super early to get to work on time? Have no fear. Here's what time you need to go to bed for an 8am rise: 10.46pm, 12.16am, 1.46am or 3.16am.

The Sleep Calculator website reads: "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.

The calculator works on the principle that everyone sleeps in about five or six cycles which last roughly 90 minutes.

Waking up midway through a cycle can leave you feeling grumpy the next day. The idea is to wake up in between cycles and feel refreshed in the morning.
