What is the short sleep gene?

Table of Contents

By 2009, the team published their first finding: There was a mutation in the gene DEC2 which caused short sleepers to stay awake longer. Since then, the team has discovered two more genes – an ADRB1 mutation and a NPSR1 mutation – which alter neurotransmitters in the human brain to create short sleep. Mice genetically engineered to have this mutation slept, on average, 1 hour less per day than controls, the researchers report online today in Neuron . The mutation affects a gene called ADRB1, which encodes a receptor for the common neural signaling molecule noradrenaline. Researchers at the University of California, San Francisco, discovered that some people have a gene that enables them to function well on six hours of sleep a night. This gene, however, is very rare, appearing in less than 3% of the population. For the other 97% of us, six hours doesn’t come close to cutting it. To date, there are no known health problems related to being a true short sleeper. In contrast, studies have found people with insomnia or those who intentionally restrict their sleep to less than six hours per night despite requiring more sleep have a higher risk of numerous health problems, such as heart attacks.

How common is the short sleep gene?

The “short sleep” gene appears to be rare. Fu estimated that it may be found in only three percent of people. Natural short sleepers remained a mystery until 2009, when a study conducted by Fu’s team discovered that people who had inherited a particular mutation in a gene called DEC2 averaged only 6.25 hours of sleep per night; study participants lacking the mutation averaged 8.06 hours. A 2019 study published in the journal Neuron (opens in new tab) also found that a mutation in [the] ADRB1 [gene] leads to natural short sleep trait in humans. The researchers noted that in the human population, this is a rare mutation, with an incidence of 4.028/100,000. The DEC2 Gene Mutation leads to “short sleep,” where carriers only need 4-6 hours of sleep to feel completely rested. Using the SNP analyzer, you can see if you are one of the lucky ones who is a carrier of this gene mutation. If the answer doesn’t lie in this gene mutation, there are many others that may be at fault. But here’s one you might not have thought of: Sleeping habits! One U.S. Bureau of Labor Statistics study, published in AP News, looked at the changes in daily habits and activities of millennials and gen-xers and found that millennials actually sleep a little bit more per day than their gen X counterparts. Vitamin B12 deficiency: a rare cause of excessive daytime sleepiness.

How do you know if you have a short sleep gene?

Is there a sleep gene?

A new study reports the discovery of the first gene involved in regulating the length of human sleep. A mutation in the gene enables some people to function well on only six hours of sleep per night. The results were published in the Aug. 14 issue of the journal Science. Generally, high achievers tend to sleep less, Brager tells CNET. If you look at US presidents, successful CEOs and military leaders, many report sleeping little but feeling fine and don’t need stimulants to stay awake, she says. Daily sleep needs fall along the bell curve like most physiological processes in nature. While most people need around eight hours of sleep to be in tip-top shape, short sleepers need only between four and six hours to function just as well. They don’t need naps or long weekend snoozes to catch up. Reasons this might happen include drinking caffeine or alcohol late in the day, a poor sleep environment, a sleep disorder, or another health condition. When you can’t get back to sleep quickly, you won’t get enough quality sleep to keep you refreshed and healthy.

What gene allows for 6 hours of sleep?

In 2009, researchers described a mother and daughter with a mutation in a gene called DEC2 who felt well rested after with about 6 hours of sleep per night. (Many experts recommend that adults get at least 7 hours.) For most people, 4 hours of sleep per night isn’t enough to wake up feeling rested and mentally alert, no matter how well they sleep. There’s a common myth that you can adapt to chronically restricted sleep, but there’s no evidence that the body functionally adapts to sleep deprivation. If you only sleep for 4-5 hours a night, you may have a sleep disorder like insomnia or sleep apnea. Poor sleep hygiene — like getting late-night bright light, eating large meals before bed, or drinking coffee too late in the day — may also keep you up past bedtime. The Impact of Getting Only 7 Hours of Sleep For most adults, there is no known negative impact to getting seven hours of sleep. But given that seven hours is the minimum that is recommended, sleeping only this amount does not leave much margin for difficulties falling asleep or staying asleep. ‘Speculative’ Results? There was a 65% higher death rate for people who regularly slept less than 5 hours on all nights, compared with people who regularly slept 6 to 7 hours per night. There was a 25% higher death rate for people who averaged 8 hours or more of sleep on all nights.

How do I know if I have the short sleep gene?

The bad news is, there is no widely available genetic test for these mutations. So there’s no surefire way to know if you’re a short sleeper or not. But if you find you’re reaching for coffee or begging for a nap, it’s because you’re not getting the amount of sleep your body needs. Genetic variations have been identified that lead to a short sleep phenotype in which individuals sleep only 4–6.5 h nightly. Negative health consequences have been identified when individuals do not sleep at their ideal circadian timing or are sleep deprived relative to intrinsic sleep need. The “short sleep” gene appears to be rare. Fu estimated that it may be found in only three percent of people. Natural short sleepers remained a mystery until 2009, when a study conducted by Fu’s team discovered that people who had inherited a particular mutation in a gene called DEC2 averaged only 6.25 hours of sleep per night; study participants lacking the mutation averaged 8.06 hours. Some People Have a Superhuman Strength: Only Needing 4 Hours of Sleep. These “short sleepers” don’t necessarily do it by choice—they’re genetically programmed to require less shut-eye. Short sleepers are people who do well with about half of the shut-eye that the rest of us require to function. The pattern of short sleep usually begins in childhood or adolescence and continues into adulthood. Researchers believe it may develop due to a gene mutation. This mutation may be what enables people to function well on fewer than six hours of sleep each night.

How common is short sleeper gene?

The “short sleep” gene appears to be rare. Fu estimated that it may be found in only three percent of people. 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. An ongoing lack of sleep has been closely associated with hypertension, heart attacks and strokes, obesity, diabetes, depression and anxiety, decreased brain function, memory loss, weakened immune system, lower fertility rates and psychiatric disorders. Females, racial/ethnic minorities, and adolescents of low socio-economic status were the most likely to think they were getting enough sleep yet report an inadequate number of hours of sleep. Sleep is essential for both physical and psychological health, as well as academic performance. What is short sleeper syndrome? Short sleeper syndrome (SSS) is a sleep condition characterized by sleeping for fewer than six hours each night. Most adults need seven or more hours of sleep each night to feel rested in the morning. Those with SSS, however, can function normally throughout the day despite less sleep.

How do you know if you have a short sleeper gene?

Diagnosis of Short Sleepers A person may be identified as a natural short sleeper if they habitually get less sleep than other people of their age without feeling drowsy or impaired during the day. Natural short sleepers typically get at least 25% fewer hours of sleep compared to their peers. Sometimes life calls and we don’t get enough sleep. But five hours of sleep out of a 24-hour day isn’t enough, especially in the long term. According to a 2018 study of more than 10,000 people, the body’s ability to function declines if sleep isn’t in the seven- to eight-hour range. Short-term or acute insomnia can be caused by life stresses (such as job loss or change, death of a loved one, or moving), an illness, or environmental factors such as light, noise, or extreme temperatures. Beneath the surface, your body is aging too, and sleep loss can speed up the process. A study done by UCLA researchers discovered that just a single night of insufficient sleep can make an older adults’ cells age quicker. This might not seem like a big deal, but it has the potential to bring on a lot of other diseases. Scientists evaluate that sleeping 5 hours a day is too little and should not be maintained for a long time if you do not want to suffer from the above diseases. Try to get 7 to 8 hours of sleep every night. And for a good night’s sleep, practice good sleep hygiene. Those with an IQ of over 125 tended to go to bed around 12:30 a.m. and wake up around 8:00 a.m. on weekdays, and go to bed around 1:45 a.m. and wake up around 11:00 a.m. on weekends. Those of normal intelligence tended to sleep from 12:00 a.m. to 7:30 a.m. on weekdays and from 1:15 a.m. to 10:15 a.m. on weekends.
