Numerous studies have found that insufficient sleep increases a person's risk of developing serious medical conditions, including obesity, diabetes, and cardiovascular disease. Lack of adequate sleep over time has been associated with a shortened lifespan.

Do high achievers sleep less?

"Daily sleep needs fall along the bell curve like most physiological processes in nature.

Do you age slower if you sleep more?

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.

How common is short sleeper gene?

The DEC2 genetic mutation that affects the body's circadian rhythm is extremely rare. It's estimated that only about 1% of the population are true natural short sleepers. What is the short sleep gene? There are actually three genes that are associated with your circadian rhythm and sleep –– DEC2, ADRB1, and NPSR1.

How rare is the short sleep gene?

Like the mutations in the other known short sleep genes, this mutation is exceedingly rare, occurring in fewer than one in 4 million people.

What is the short sleeper gene?

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.
