In today’s fast-paced world filled with screens and distractions, quality sleep is increasingly rare. Alarmingly, over 1/3 of the US adult population is not achieving the recommended amount of sleep nightly.
However, a select few possess unique biological advantages, allowing them to thrive on much less sleep.
Believe it or not, around 1 to 3 percent of the population are “short sleepers” who function optimally on just 4 to 6 hours of sleep each night.
What’s even more fascinating is that scientists are beginning to uncover the reasons behind this phenomenon. They are exploring whether others may eventually gain this ability.
This suggests that, in the not-so-distant future, you may only need four hours of sleep for optimal functioning.
Who Are the Hidden Superheroes?
Natural short sleepers do not achieve their unique traits through mindset or willpower; it is a biological adaptation.
Recent research has identified specific genes that allow some individuals to sleep significantly less without negatively impacting their health.
A notable discovery involves a gene called December 2nd, which regulates orexin levels—a brain chemical that enhances alertness.
While low orexin levels can lead to narcolepsy, those who are naturally short sleepers seem to produce elevated amounts, enabling them to stay awake on less rest.
When researchers introduced this mutation into mice, they found that these mice required less sleep without experiencing cognitive decline typically associated with sleep deprivation.
Since then, at least seven genes have been implicated in this unique sleep pattern, consistently yielding shorter sleep cycles without apparent drawbacks.
According to Professor Guy Leszziner, a neurologist and sleep expert, the evidence points to genetic factors as the key determinant of natural short sleepers.
Such individuals are rarely seen in clinics, as their unique sleep patterns are often mistaken for normalcy unless pointed out by someone close.
“Short sleepers often don’t realize their patterns are unusual until others highlight it,” he explains. “There may be others with similar patterns, particularly if there’s a family history, so it feels normal to them.”
While natural short sleepers are genetically uncommon, research into their mechanisms is rapidly gaining momentum.
This leads to intriguing possibilities: instead of waiting for nature to endow us with this gift, could we one day engineer it?

Introducing CRISPR
CRISPR is a revolutionary gene-editing technology granting scientists the capability to alter DNA with astounding precision. Initially part of bacterial defense systems, it now stands as one of the most potent tools in modern biology.
This technology employs enzymes as “programmable scissors.”
By assigning short genetic addresses to these enzymes, scientists can direct their actions precisely within the genome. Once they cut, the cell’s repair mechanisms can delete genes, correct mutations, or insert new DNA.
Currently, CRISPR is mainly utilized for treating genetic conditions such as sickle cell disease. However, as technology progresses, many researchers speculate it could extend to enhancing human capabilities, including sleep.
At GITEX Global, Dr. Trevor Martin, CEO of genetic engineering firm Mammoth Biosciences, shared:
“They don’t just persevere; they actually require only three hours of sleep. While we discuss longevity, imagine if everyone had access to that!”
His company is focused on creating new CRISPR tools that are smaller and simpler to introduce into human cells than earlier versions.
“Our mission is to eradicate genetic diseases,” he states in BBC Science Focus. “We are developing CRISPR technology capable of extensive editing in every cell in the body.”
While Mammoth is currently addressing rare genetic conditions like familial chylomicronemia syndrome, Martin emphasizes the broader potential of this technology, stating, “There’s no reason to stop there.”
So, how feasible is it to edit someone to become a short sleeper? Leszziner asserts it’s theoretically achievable, though complex.
“In theory, if all responsible genes can be identified, altering someone’s genetic makeup is possible,” he explains. “However, it is not as straightforward as simply removing or modifying one gene.”
Social considerations also come into play. “If everyone suddenly had three to four extra hours each day, society would need a significant reconfiguration,” Leszziner notes. “Would those hours be utilized for work or enjoyment? The answer remains uncertain.”
A “One-Time” Upgrade
Concerns may arise that, even if such a treatment becomes available, access could be limited to a privileged few.
Fortunately, Martin reassures that this technology is inherently designed for accessibility.
“The incredible aspect of genetic medicine, often overlooked, is that it can be a one-time solution,” he explains. “You won’t need continuous medication; a single visit to a healthcare provider could suffice. While cost is a topic, lengthy medical infrastructures won’t be necessary.”
For now, transforming someone into a short sleeper remains hypothetical. Yet, the science of sleep efficiency is expanding rapidly, and CRISPR technology is progressing even faster.
For the first time, researchers can plausibly assert that it might be feasible to increase your waking hours by three to four hours each day.
This may not happen today or tomorrow, but soon, a day will come when sleeping just four hours will be a reality. Prepare yourself to grasp that potential!
