Tired? We all know the feeling; irritable, groggy and exceptionally lazy. Chances are you didn’t sleep enough last night, or the past few nights. But what exactly is “enough sleep?” And more importantly, can you ever “catch up” on it? While the very function of sleep is still debated by scientists, we do know that it’s necessary to function efficiently and productively. After all, we spend 24 years of our lifetime sleeping, it had better be important. Researchers have tested how much is required each night by assigning groups of people to four, five, and eight hours of sleep over extended periods of time. After 14 days, those with eight hours of sleep exhibited few attention lapses of cognitive issues; however, those with six or four hours of sleep showed a steady decline. In fact, after only two weeks, the six hour group showed a similar reaction time to a person with a blood alcohol concentration of 0.1%, which is considered legally drunk. The four hour sleepers suffered even more, occasionally falling asleep during their cognitive tests. In both groups, brain function decreased day by day, almost linearly with no sign of leveling off. Scientists have dubbed this cumulative effect as sleep debt. So can we recover from it? After a night or two of little sleep, studies show that the body and brain can fully recover with a few nights of good sleep. However, with long term sleep deprivation on the scale of weeks to months, the recovery of cognitive function is much slower, requiring many more nights of quality sleep. On the timescale of months to years, it is unknown whether brain function can be fully repaired, or if it causes permanent damage. Paradoxically, with chronic sleep deprivation, your sleepiness or how tired you feel does eventually level off, meaning that you become less and less aware of your objective impairment over time. So how long should you sleep? Most studies tend to show that seven to eight hours of sleep is the average ideal for humans. Apart from the 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. On the flip side, studies have shown that while sleeping more than eight hours does not impair brain function, it also carries an increased risk of heart disease, obesity and diabetes, and a 30% increased risk of mortality! So too much sleep may also be a bad thing. But variation most certainly exists, and our genetics play a large role. In fact, individuals genuinely unaffected by only six hours of sleep were found to have a mutation of a specific gene. When scientists genetically engineered mice to express this gene, they were able to stay awake for an extra 1.2 hours than normal mice. It turns out these short sleepers have more biologically intense sleep sessions than the average person. Ultimately, while it’s important to know the ideal average of seven to eight hours exists, let your body and brain help you figure out its own needs. After all, no one shoe size fits all.

I wanna know if my sleep deprivation is causing me to hallucinate at 2:44 when I'm reading the word "better"…
I am literally GOING to die
I'd rather be dreaming then be awake to this sad realities lol.
Surprisingly I can go on like 3~4 hours of sleep and still feel energetic and awake,I though this was normal until my friends complained that they cant get less than 8 hours. This is actually convenient because I ultimately have more time to do other stuff such as homework or anything else.

Well i all ready have diabetes i hade it for 3 years and i have school in 7 or 8 days 😭 i can't sleep 😭😭😭😭😭😭😭😭
Watching this while I still have 8 hours to get up…yayyy.
Would have been nice to know which gene ur referring to.
higher risk of death?! yes!
I call bullshit on that mutation that allows you to sleep less with no repercussions, I'm sure such ppl exists, but the explanation sounds stupid, a gene codes a protein, a mutated gene codes an slightly different protein, even if the protein is folded differently, the net effect would be the variation in concentration of the original protein or it's absence in favor of a different protein.
See the problem? if by regulating the concentration of one protein you could just like that cut the sleep requirement of a person by two hours, pharmaceutical companies will go nuts on it, that kind of supplement could potentially become standard around the world.
It would've helped us more if you told us how to test our so called 'objective impairment'.
well I guess 4 hours isn't that great…
