Biohacker reveals simple formula that works out the ‘perfect time’ you should be going to bed at
The doctor revealed exactly how to calculate your ideal wake-up time to avoid feeling 'groggy'
A doctor has revealed a mathematic formula that ensures you wake up feeling ready for the day, after being 'obsessed with getting the best sleep possible'.
Biohacker Dr Charles Puza has shared the ultimate life hack - and it may be life-changing for people who struggle to fully wake up in the morning.
If you're the kind of person who wakes up feeling groggy no matter how much sleep you have, this advice is right up your street.
While most experts recommend getting between seven and nine hours sleep per night, Puza has come up with an easy way to create a completely personalised sleep schedule.

It turns out that your 'ideal bedtime' can be revealed by doing some simple calculations.
Speaking to his Instagram followers, the doctor said: "Does your nap feel more restful than a full night’s sleep? Ever wake up from 8+ hours of sleep and still feel groggy?"
Yes, and yes again.
Providing an explanation, he added: "It’s because you’re going to bed and waking up at the wrong time. You should be timing your sleep to align with natural sleep cycles of around 90 minutes."
According to experts, sleep cycle goes through four stages.
Research suggests that stage one can last for 1-7 minutes, stage two is 10-25 minutes, and stage three - also known as delta sleep or deep sleep - is 10-40 minutes.
REM sleep, which is the deep sleep we hear about more commonly, can last anywhere between 10 to 60 minutes.
In order to work out your perfect bedtime, the formula is simply as follows...
Six full sleep cycles of 90 minutes each equals 7 hours and 30 minutes.
Add another 15 or so minutes to give yourself time to fall asleep, and you arrive at 7 hours and 45 minutes.
Finally, subtract that number from the time you need to wake up to arrive at your bedtime.
Hoorah! A refreshing wake-up awaits you.
An example of this could be needing to be awake for 7am.
Working backwards by 7 hours and 45 minutes would come to a bedtime of 11:15pm.
Puza said he discovered the method after becoming obsessed with maximising the quality of his own sleep.
He explained: "I’m obsessed with getting the best sleep possible - it's essential for anti-aging, muscle recovery, memory and brain health, and so much more!"
