Here Is Exactly When You Should Sleep In Order To Wake Up Feeling Completely Refreshed

We have all been there, so tired you can’t keep your eyes open.

You have a commitment just on the other side of sunrise and go to bed early because you need to be up early. But,  despite the 10 hours of sleep, you find yourself feeling more tired.

Research now shows you might be doing it wrong.

Sleeping more does not necessarily leave you feeling more refreshed.

Someone has created a ‘sleep calculator’, being used on Blinds Company site, so you can work out when we need to hit the sack in the click of a button.

A healthy night of sleep is completed in cycles rather than hours. If you wake up at the wrong time during a sleep cycle, you’ll find yourself more tired, regardless how long you’ve been asleep.

7 am Wakeup

Need to make sure you’re awake and getting out of bed at 7 am? Then you need to go to bed at either 9:46 pm or 11:16 pm.

If you’re having a late night and you don’t fancy either of these, then 12:46 am and 2:16 am will also work.

The sleep calculator factors in 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.

6 am Wakeup

To get up at 6 am, you’re looking at a bedtime of 8:46 pm, 10:16 pm or even 11:46 pm or – if you’re feeling like a real night owl – 1:16 am.

8 am Wakeup

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 8 am rise: 10:46 pm, 12:16 am, 1:46 am or 3:16 am.

What are sleep cycles?

One sleep cycle lasts about 90 minutes and includes five stages of sleep – four stages of non-rapid eye movement (NREM) sleep and one stage of rapid eye movement (REM) sleep.

We move from light sleep in Stage 1 to a very deep sleep in Stage 4. It is difficult to wake someone in Stage 4 of a sleep cycle, which is why you might feel more groggy if you wake up during this stage.

The fifth stage, REM sleep, is when most dreaming occurs.

Precise Wake-up Times

For example, if you know getting out of bed at 6:35 is the optimum time so you can not miss the train and be punctual for work, enter it into the sleep calculator and you’ll get a result.

For a 6:35 am rise time, go to bed at 9:21 pm, 10:51 pm, 12:21 am or 1:51 am.

According to the Sleep Calculator website, “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.

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.
