Why eight hours a night isn’t enough, according to a leading sleep scientist
We're always told we need to get our eight hours of sleep - but who made that figure up? Was it just plucked out of thin air? Sure, we'll feel tired the next day if we only get a few hours of sleep overnight.
But according to Matthew Walker, author of book Why We Sleep , and Professor of Neuroscience and Psychology at the University of California, it's not just yawn-prevention that's the reason we're advised to get a full night's sleep. It seems there are actually some serious bodily effects you didn't realise could occur as a result of lack of sleep, and it gives real reasoning to the advice to get eight hours a night. Walker spoke to Tech Insider to explain just what happens inside your body if you don't catch enough zeds:.

But it's not just your everyday memory that might suffer, Walker also points out a scientific connection between not getting enough sleep and the onset of Alzheimer's disease. Sleep usually washes away this protein, so the less sleep you get, the more will build up - and the higher your chances of developing Alzheimer's.

It's normally when you feel tired and run down that you get ill, we all know that. But this lethargy can also pave the way for more serious illnesses to bed in. Walker notes that lack of sleep is most likely to play a role in the development of bowel, prostate and breast cancers.
And this isn't just some loose theory, either. During deep sleep, as well as getting a rest, your body experiences what Walker describes as a "reboot of the cardiovascular system". Your heart rate drops and your blood pressure goes down, both of which are vital for good heart health. And there's some firm evidence to prove this correlation.
