A paper published in the scientific journal Sleep this August 1 announces the discovery of a genetic mutation that researchers say explains why some people only need to sleep for about 6 hours per night, maybe even less. Evidence at hand indicates that this genetic mutation that scientists suspect is to blame for the fact that some people need just a few hours of rest to be able to function normally also helps make folks more resilient to the effects of sleep deprivation.
In their paper documenting the discovery of this mutation, researchers with the American Academy of Sleep Medicine explain that their investigation boiled down to analyzing the sleep patterns and the genomes of 100 pairs of twins.
During the investigation, it was discovered that some of the twins only needed about 6 hours of sleep per night to be able to function properly the following day. More precisely, they were found to experience 40% fewer lapses of performance when sleep deprived. Commenting on these findings, study lead author Renata Pellegrino said, “This work provides an important second gene variant associated with sleep deprivation and for the first time shows the role of BHLHE41 in resistance to sleep deprivation in humans.

Interestingly enough, a data obtained during a recent survey carried out by the Centers for Disease Control and Prevention in the US indicates that about 28% of the adults living in this country rest for merely 6 hours, sometimes even less, within a 24-hour period. New research suggests that we shouldn't blame our modern lifestyles and electronic devices for lack of sleep.It turns out people living thousands of years ago only got six or seven hours of sleep per night. Researchers studying three groups of hunter gatherers in Namibia, Tanzania and Bolivia with no access to technology have found they still only sleep for around 6.5 hours per night. The researchers recorded the sleeping habits of 94 individuals around the clock to collect data representing 1,165 days in all.What they found was a surprising similarity across those three groups. To ensure that the data obtained while studying their sleep patterns and genetic makeup would be as accurate as possible, the researchers only enrolled pairs of twins of the same gender. Besides, these twins had an easier time staying alert after going as much as 38 hours without any sleep.

When compared to their siblings, they also slept 1.5 hours less when allowed to rest and recover from the experience of staying awake for 38 hours in row. According to the American Academy of Sleep Medicine researchers behind this investigation, this mutation is a variant of a gene called BHLHE41. Most adults appear to need at least seven hours of quality sleep each night for optimal health, productivity and daytime alertness,” added Dr.
