Wanna wake up feeling refreshed at 7am?
Best time to go to sleep if you need to wake up feeling refreshed at 7am
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.
Do not just think by getting more hours of
sleep, you will be more refreshed in the office the next day. Apparently, it is
a bit more complicated than that.
However, 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 is all 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 will find yourself more tired - even if you were
asleep for longer.
If you need to get up at 7am
Need to make sure you are awake and getting
out of bed at 7am? Then you need to go to bed at either 9.46pm or 11.16pm.
If you are having a late night and you do not
fancy either of these, then 12.46am and 2.16am will also work.
The sleep calculator factors in the average of
14 minutes it takes people to naturally fall asleep, so you do not necessarily
need to be in bed by this time.
If you need to get up at 6am
To get up at 6am, you're looking at a bedtime of 8.46pm, 10.16pm
or even 11.46pm or - if you're feeling like a real night owl - 1.16am.
How about 8am?
Do not need to get up super early to get to work on time? Have
no fear. Here is what time you need to go to bed for an 8am rise: 10.46pm,
12.16am, 1.46am or 3.16am.
What are sleep cycles?
A sleep cycle lasts about 90 minutes, during which time we move
through 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 groggier if you wake up during this stage.
The fifth stage, REM sleep, is when most dreaming occurs.
You can even be precise
For example, if you know getting out of bed at 6:35 is the
optimum time so you cannot miss the train and be punctual for work, enter it
into the sleep calculator and you will get a result.
For a 6.35am rise time, go to bed at 9.21pm,
10.51pm, 12.21am or 1.51am.
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.
"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.
