Sleep is a vital part of our lives, but it can often feel like a waste of time. Many people wonder if it is possible to train themselves to need less sleep or none at all. While it may be possible to train yourself to need less sleep, it is not recommended due to the adverse effects of sleep deprivation on both physical and mental health. However, there are a few very rare individuals who can function well on less sleep, known as short sleepers or the sleepless elite.
| Characteristics | Values |

It is possible to train your body to sleep less, but it is not recommended due to health risks
It is technically possible to train your body to sleep less, but it is not recommended due to the adverse health effects of sleep deprivation. While you may be able to function on less sleep, your body will still experience the negative consequences, and you may not even realise it.
Some people claim to be able to get by on very little sleep, like Margaret Thatcher, who allegedly slept four hours a night, or Leonardo Da Vinci and Thomas Edison, who supposedly only needed a couple of hours. However, these claims are often exaggerated or simply untrue. For example, Napoleon allegedly said that sleep was only for the weak, but in reality, he slept quite a lot.
There are, however, a few very rare individuals who can function on five hours of sleep or less without any negative effects. These people are sometimes called the "sleepless elite" and have a mutated gene called hDEC2, which allows their bodies to get the required rest from fewer hours of sleep.
For those without this mutated gene, it is still possible to reduce your sleep to about six hours a night, plus a short nap during the day, but it must be done gradually. In one study, participants who regularly slept seven to 8.5 hours a night were asked to go to bed later each night while waking up at the same time each morning. They pushed back their bedtime by one hour during the first week and then by 1.5 hours for the next three weeks. After this adjustment period, they were able to function and get high-quality sleep on just six to 6.5 hours of sleep each night.
However, just because it is technically possible to train your body to sleep less doesn't mean you should. Sleep is vital for both physical and mental health, and not getting enough sleep can lead to a range of issues, including obesity, heart disease, high blood pressure, reduced alertness, impaired judgment, diminished memory, and increased stress hormones. It is always better to listen to your body and get the amount of sleep it needs to function optimally.

Genetics play a role in how much sleep you need, with some people able to function on less sleep
While it is possible to train yourself to need less sleep, it won't work for everyone. The amount of sleep a person needs is influenced by various factors, including age, physical activity, and genetics.
Genetics plays a significant role in determining an individual's sleep needs and preferences. Research has identified a mutated gene called hDEC2 in individuals who require less sleep, known as "short sleepers" or the "sleepless elite." These individuals can function optimally on just a few hours of sleep each night. For example, a 2009 study found a mother and daughter who consistently went to bed late but woke up bright and early, carrying the hDEC2 gene mutation.
Additionally, studies on mice, flies, and fruit flies have further supported the role of genetics in sleep duration. Researchers found that altering specific genes in these organisms influenced their sleep patterns, with some sleeping less and exhibiting increased resistance to sleep deprivation.
It is important to note that while genetics influences sleep duration, it is not the sole factor. Environmental, cultural, and behavioral factors also play a role. For example, people in hot climates often take afternoon siestas, resulting in shorter sleep durations at night. Similarly, age and daily schedules can impact an individual's sleep timing and duration.
While you may not be able to alter your genetics, optimizing your sleep habits can help ensure you get the most out of the sleep you do get. This includes practices such as avoiding large meals late in the evening, addressing worries before bed, and maintaining a dark and quiet bedroom environment.

Sleep is vital for physical and mental health, and deprivation can lead to serious issues
Sleep is essential for the brain and body to function optimally. When an individual does not get sufficient sleep, their brain is unable to repair or build new pathways, leading to impaired cognitive performance and slower reaction times. Sleep deprivation can also lead to physical and mental health issues, such as obesity, heart disease, and high blood pressure. Additionally, it can cause an increase in stress hormones, such as cortisol and adrenaline, as the body attempts to compensate for fatigue.
The amount of sleep a person needs varies, but most healthy adults should aim for seven to nine hours each night. However, about one-third of Americans get less than seven hours of sleep, according to the Centers for Disease Control and Prevention. This can lead to reduced concentration, confusion, distress, and impaired driving ability.
While it may be possible to train yourself to need less sleep, experts advise against it. Sleep deprivation can have adverse effects on both physical and mental health, and there is a risk of serious issues such as heart disease and high blood pressure. In one study, participants who slept only six hours a night experienced similar cognitive and reaction time impairments as those who went two full nights without sleep.
Some individuals, known as "short sleepers," possess a mutated hDEC2 gene, allowing them to function on fewer hours of sleep without negative consequences. However, for most people, getting less than six hours of sleep will impact their ability to function effectively.
Overall, sleep is vital for physical and mental health, and deprivation can lead to serious issues. While you may be able to train yourself to need slightly less sleep, it is important to prioritize getting adequate rest to maintain optimal health and well-being.

Sleep deprivation affects performance and can be compared to alcohol intoxication
While it may be possible to train yourself to need less sleep, sleep deprivation can have a detrimental impact on performance, comparable to the effects of alcohol intoxication.
Several studies have found that the cognitive and physiological impairments caused by sleep deprivation are similar to those caused by alcohol. Participants in these studies were tested under two conditions: after staying awake for extended periods and after reaching a certain blood alcohol concentration (BAC). The results showed that being awake for 17 hours produced effects similar to a BAC of 0.05%, while being awake for 24 hours was comparable to a BAC of 0.10%. In the United States, a BAC of 0.08% or higher is considered legally intoxicated for driving.
In a driving performance study, sleep deprivation caused greater overall impairment than alcohol intoxication, with more pronounced deterioration in lateral tracking, braking reaction time, and lane-changing time. The participants reported feeling less impaired after drinking coffee when sleep-deprived, but their actual driving performance did not improve, and lateral control and lane-changing time were significantly impacted.
The effects of sleep deprivation on performance are well-documented. In one study, participants who reduced their sleep to six hours a night experienced declines in cognitive performance and reaction times similar to those who went two nights without sleep. This highlights that even a small reduction in sleep can have significant consequences.
While some individuals, known as "short sleepers," may be able to function on less sleep due to a mutated hDEC2 gene, for most people, sleep deprivation can have adverse effects. It is essential to prioritize getting the recommended seven to nine hours of sleep per night for optimal brain and body function.

There are strategies to optimize sleep, such as avoiding screens and a cool bedroom
While some research suggests that it is possible to train yourself to need less sleep, it won't work for everyone. Most healthy adults should aim for seven to nine hours of sleep each night, but about one-third of Americans get less than seven hours. Sleep is essential for cognitive performance, and insufficient sleep can impair us in ways we are often unaware of.
If you're looking to optimize your sleep, one strategy is to avoid screens before bed. Blue light from electronic devices like phones, computers, and TVs can suppress melatonin production and negatively affect sleep quality, duration, and wake times. To mitigate this, you can set a digital curfew by turning off electronic devices at least an hour before bedtime. Creating a tech-free bedroom can also help.
Another strategy is to keep your bedroom cool, dark, quiet, and distraction-free. Ideal sleeping temperatures are between 60 and 68 degrees Fahrenheit. Using a cooling mattress pad, lightweight bedding, or an electric fan can help achieve a comfortable temperature. Additionally, consider room-darkening blinds or a sleep mask to block out light. If noise is an issue, try earplugs or a white noise machine.
Other tips for optimizing sleep include maintaining a healthy body weight, exercising regularly, and eating nutritious foods, as well as having a regular bedtime routine. It's also important to avoid large meals, spicy foods, caffeine, and alcohol before bed, as these can disrupt sleep. While it may be tempting to train yourself to need less sleep, remember that adequate sleep is crucial for the brain and body to function optimally.
