Why do some people sleep 6 hours?

The good news is that researchers at the University of California-San Francisco have identified a family with a genetic mutation that causes members to require only six hours of sleep a night. They even managed to create mice and fruit flies with a similar mutation who also had short sleep cycles.

Are there some people that only need 6 hours of sleep?

unless you happen to carry a rare genetic mutation. According to a new study, some people who function normally on just 6 hours of sleep harbor an altered version of a particular gene, the second gene so far linked to short sleep.

Can you be rested on 6 hours of sleep?

Young adults can get 7 to 9 hours of sleep as recommended by the National Sleep Foundation — with 6 hours being appropriate. Less than 6 hours is not recommended.

Is 6 hours of sleep enough for a teenager?

Sleep research suggests that a teenager needs between eight and 10 hours of sleep every night. This is more than the amount a child or an adult needs. Yet most adolescents only get about 6.5 – 7.5 hours sleep per night, and some get less. Regularly not getting enough sleep leads to chronic sleep deprivation.

Why does 6 hours sleep feel better than 7?

So why do people think they are able to function optimally on 6 hours of regular sleep? This is because of a natural human phenomenon known as ‘renorming’. If someone who regularly sleeps 8 hours a night stays up for 24 hours, the deterioration of how they feel will be evident to them.

Can I survive on 7 hours of sleep?

Best survival rates were found among those who slept seven hours a night. A group sleeping eight hours was 12% more likely to die within the six year period than those sleeping seven hours, other factors being equal. Even those with as little as five hours lived longer than those with eight hours or more nightly.

Is 6 hours of sleep enough for gym?

So if you got seven to eight hours of sleep the night before, get up and hit the gym! But if you’ve been clocking less than six hours most nights that week, you probably want to savor that extra hour of sleep. If you skip it, chances are you’ll log a subpar workout, anyway.

Is 6 hours of sleep enough for an athlete?

How much sleep do athletes need? Pro athletes typically need more than most—it’s recommended that they get 8-10 hours every night. But for the average adult, aim for seven to nine hours of sleep a night to avoid the effects of chronic sleep deprivation.

Will 7 hours of sleep stunt growth?

A single night of no sleep will not stunt growth. But over the long term, a person’s growth may be affected by not getting the full amount of sleep. That’s because growth hormone is normally released during sleep.

Are there two types of short sleep genes?

After a decade of searching, the UC San Francisco scientists who identified the only human gene known to promote “natural short sleep” – lifelong, nightly sleep that lasts just four to six hours yet leaves individuals feeling fully rested – have discovered a second. Ying-Hui Fu, PhD, led the research teams that discovered both short sleep genes.

Why do some people naturally sleep less than 6 hours a night?

Scientists identified a gene that causes people to naturally sleep less than six and a half hours each night without any apparent ill effects. The findings reveal a mechanism affecting quality sleep and suggest an avenue to investigate for new sleep treatments.

Is there a genetic component to sleep disorders?

Research suggests that other sleep disorders also have a genetic component. Narcolepsy is a neurological disorder characterized by daytime sleepiness, cataplexy (or sudden paralysis), hallucinations at sleep onset, and disturbed nighttime sleep.

Why do some people have short sleep cycles?

Using whole exome genome sequencing, the researchers searched for gene mutations that only the naturally short sleepers had. They found a rare mutation in the ADRB1 gene that was being passed through the family. Family members who inherited one copy of this mutant gene had a shortened sleep cycle.
