Short-Sleeper : a Genetic Mutation For Better Future
For normal adults, the normal sleep is 7.5 up to 9 hours everyday. For those people who sleep less than it should be will causing a Sleep deprivation, the condition of not having enough sleep; it can be either chronic or acute. A chronic sleep-restricted state can cause fatigue, daytime sleepiness, clumsiness and weight loss or weight gain.It adversely affects the brain and cognitive function.
Even though many doctors advice for people to have enough sleep like it should be to avoid the sleep deprivation, the sleepless effect doesn’t work out for the short-sleeper. A short-sleeper woman from Miami, Florida has been living with only spent 4 hours sleep everyday.
Abby Ross the short-sleeper is a retired psychologist. She shares her experience as a short-sleeper to BBC :
“It’s wonderful to have so many hours in my day – I feel like I can live two lives,”
Short-sleeper like Ross never feel lethargic, nor do they ever sleep in. They wake early – normally around four or five o’clock – raring to get on with their day. What does the factor causing people can have more efficient sleep than others who spent almost half of their day snoozing?
In 2009, a woman came into Ying-Hui Fu’s lab at the University of California, San Francisco, complaining that she always woke up too early. The woman explained that she actually went to bed around midnight and woke at 4am feeling completely alert, and it happens as well to some of her family member.
Later on, Fu and her colleagues compared the genome of different family members. Researchers have found a genetic mutation in two people who need far less sleep than average, a discovery that might open the door to understanding human sleep patterns. The finding, published in the Friday issue of the journal Science.
The gene mutation of short-sleeper was found by scientists at the University of California, San Francisco, who were conducting DNA screening on several hundred blood samples from people who had taken part in sleep studies. They discovered a tiny mutation in a gene called DEC2 that was present in those who were short-sleeper. However, short-sleeper is different with insomnia, which is a sleep disorders.
For a short-sleeper, they can spent more time to do many things when everybody spent their time to sleep. A successful people does it, most of the successful people are sleepless. Do we need to have a genetic mutation DEC2 to be a short-sleeper? Not really.
An independent sleep consultant, Neil Stanley says:
“The most effective way to improve your sleep is to fix your wake-up time in the morning.”
When people try to set their “body alarm” to wake up early, the body will respond and get used to it. That’s not an easy work to be done, but it will automatically turn into a habit if we do it everyday.
