Many of today’s pressures mean we don’t let ourselves get enough sleep. What can be difficult for some is working out how much they really need or still waking up tired in the morning.
A new online calculator found at https://www.hillarys.co.uk/static/sleep-calculator/ could help you make sure you get enough time in bed to achieve a complete restful night’s sleep yet waking out of the right sleep stage so you feel refreshed and ready to go.
The calculator claims to use a formula based on the body’s natural rhythms. Put in a wake time, say 7 am, and the calculator claims to work out the best time to go to bed so you wake up feeling great.
There does appear to be some science behind it as the human sleep cycles operate on a 60-90 minute time frame. Waking out of deep or slow wave sleep can leave you feeling groggy and tired in the morning as the ‘sleep inertia’ wears off. How well the calculator does to estimate your particular sleep cycle? Only you can be the judge, try it and see.
