It’s not easy to get your eight hours of sleep every night, in fact we would say it’s damn near impossible.

And while we know that we should be getting eight hours, maybe we don’t actually know the real danger behind not getting enough sleep.

A sleep expert has revealed what happens when you don’t get enough sleep and to be honest, it’s rather shocking!

Matthew Walker is professor of neuroscience and psychology at the University of California and author of the book Why We Sleep. So he knows what he’s talking about.

He wrote about the dangers of not getting enough sleep for the Business Insider.

‘We certainly know that a lack of sleep will actually prevent your brain from being able to initially make new memories, so it’s almost as though without sleep the memory inbox of the brain shuts down and you can’t commit new experiences to memory,’ he explained.

So basically without sleep we won’t be able to remember anything! This is especially dangerous if we’re studying for exams.

And on top of that, lack of sleep might actually lead to Alzheimer’s! When we don’t get enough sleep our brain starts to create a toxic protein called beta-amyloid which is linked to Alzheimer’s.

When we sleep we usually get rid of these toxins and without enough sleep we’ll store these proteins.

Oh and he also claims that it can effect our reproductive system and our cancer fighting cells. He says that men who don’t get enough sleep will produce a lack of testosterone.

‘After just one night of four to five hours of sleep, there is a 70 percent reduction in critical anticancer-fighting immune cells called natural killer cells,’ he wrote.

‘And that’s the reason that we know that short sleep duration predicts your risk for developing numerous forms of cancer.’

He added that if we are awake for 19 hours we have the same mental capacity of a drunk person.
