Calculator Tells You When To Go To Bed To Avoid Feeing Tired The Next Day
A company has created a calculator which works out when you need to go to bed so that you don't wake up feeling tired.
The general rule is that you need five or six 90-minute sleep cycles a night to get enough rest for the following day.
But sometimes that's not possible for whatever reason, so if you tend to miss out on these cycles, the sleep boffins at Hillary's have come to the rescue to explain when you should head to bed.
For example, if you want to be up by 6am, you should aim to be tucked up by either 8.46pm or 10.16pm in order to catch the right sleep cycle. Failing that, you should aim for 11.46pm or 1.16am.
This is taking into account the 14 minutes it takes, on average for a person to fall asleep after getting into bed.
But rather than having to work it all out for yourself, Hillary's has also come up with a calculator that does all that for you.
Speaking to The Mirror, sleep expert Lucy Askew said it was vital people made sure they were getting enough rest every night.
She told the publication: "It is so important to get a good night's sleep as this can really affect how you function the next day. Getting decent sleep helps with your productivity, concentration levels and your cognition so it affects almost every aspect of your life.
"Not only this, but sleep can lower your risk of things like heart disease, helps keep your immune system strong and it is vital for supporting your mental wellbeing."
Failing to get enough kip, she says, could lead to all manner of health problems.
She explained: "Lack of sleep has a bigger impact on your health than you may realise. Not only can it affect the way you function the next day, but it can also change your appearance and age your skin quicker. Being sleep deprived can also cause your skin to break out.
"More serious health problems associated with not getting enough sleep include high blood pressure, diabetes and heart attacks. There are also studies that link not getting enough shut-eye with depression."
And if you needed any more warning from an expert about how bloody important it is to get your fair share of sleep every night, then here it is.
Last year, Neil Stanley, author of How To Sleep Well (so he probably knows his stuff), explained: "Individual sleep need is like height - we are all different and it is to a large degree genetically determined.
"Anywhere between about four and eleven hours can be considered normal, but getting just one hour less sleep a night than you require can have measurable effects on your physical and mental health."
Quite how anyone is managing to get 11 hours of sleep a night I don't know, but it's mighty impressive. Kudos.
Neil also suggested using sleeping apps as well but recommends visiting your GP is you have tried some of these and they aren't working
