How Much Sleep Do You Really Need?
You might not get the recommended eight hours of sleep each night, but is that really such a bad thing?
It depends, according to the video below by asapSCIENCE, a YouTube channel focused on exploring scientific questions. On one hand, studies have found that those who got eight hours of sleep for an extended period of time experienced fewer attention lapses and cognitive issues compared to those who consistently slept either six or four hours each night.
In fact, after only two weeks, study subjects who consistently got six hours of sleep displayed reaction times similar to those of an intoxicated person.
On the other hand, however, there are people who are genuinely unaffected by getting only six hours of shuteye. These individuals can thank genetics for this, as a gene mutation allows them to have a more biologically intense sleep session than the average person.
