How Much Sleep Do You Actually Need? Horrifying Video Highlights The Effects Of Lack Of Sleep

By now, we all know that a lack of sleep impacts your productivity. However, we generally don’t give much thought to it. That is, until research like this comes along.

A new video has gone viral after clearly demonstrating the horrifying facts of sleep deprivation and the unexpected effects it can have on your mind and body.

The folks at AsapSCIENCE came up with a combination of graphics and facts from various global studies on sleep to shine a light on how much sleep you really need and what exactly happens to your brain when you don’t get it.

The video has already clocked up 6.5 million views since it was first published earlier this week. Alarming headlines on the impact of sleep deprivation it draws attention to include:

Lack of sleep has the same cognitive impact as drunkenness

In one study from the University of Pennsylvania, researchers split a test group of people up into three categories; for 14 days, one group slept for eight hours a night, the second group slept for six hours a night, and the third group slept just four hours a night. Cognitive tests after the fortnight period showed those that had had six hours sleep a night showed a similar reaction time as people whose blood alcohol content was at 0.1 percent – in other words, the equivalent of being legally drunk.

Sleep deprived people aren’t aware of how sleep deprived they are

With chronic sleep deprivation, researchers have found that how sleepy you feel does eventually level off, meaning that, alarmingly, you become less and less aware of your own impairment through sleep deprivation over time.

Less than seven hours a night leads to a 12% higher risk of death

Apart from cognitive issues, individuals who consistently sleep less than seven hours a night have an increased risk of heart disease, obesity and diabetes – not to mention a 12% higher risk of death.

However, the video also made it clear that your genetics are a factor when it comes to how much sleep you actually need every night. Some people able to do just fine on only 6 hours of sleep, thanks to specific genes.
