Many people wish they could reduce the amount of sleep they need each night, but is it possible to train your mind to use less sleep? Scientific research shows that some people are genetically predisposed to thrive on less sleep. These so-called 'short sleepers' have a mutated gene called hDEC2, which allows their bodies to get the rest they require from just a few hours each night. However, for those not genetically predisposed to get by with little sleep, there are still ways to optimise your sleep habits and routine to make the most of the sleep you get.

What You'll Learn
The dangers of sleep deprivation
While some people claim that it is possible to train your mind to use less sleep, this idea is not supported by scientific evidence. Sleep expert Jim Horne suggests that people can cut down their regular sleep to about six hours a night, plus a short nap during the day, as long as they do it gradually. However, studies have shown that those who received six hours of sleep per night performed at the same level as those who had been awake for 24 hours. Their cognitive performance and reaction times dropped as much as they did in people who went two full nights without sleep.
Now, here are the dangers of sleep deprivation:
Sleep deprivation can have serious negative consequences on both mental and physical health. It impairs cognitive performance and reaction times, making it difficult to retain information, engage in complex thinking, and stay focused. Sleep deficiency has been linked to physical health issues such as obesity, high blood pressure, and heart disease. It also affects the immune system, making it harder for the body to fight off illnesses and increasing vulnerability to respiratory infections and existing respiratory diseases.
Additionally, sleep deprivation disrupts the balance of hormones that control hunger and fullness, leading to potential weight gain and an increased risk of diabetes. It can also cause irritability, mood changes, and emotional distress, as well as increased production of stress hormones. Sleep deprivation can make it difficult to get quality sleep, leading to a cycle of chronic sleep loss and further negative impacts on health and daily functioning.
Furthermore, sleep deprivation can impair judgement, similar to intoxication with alcohol. People may not realize how impaired they are due to sleep loss, which can lead to dangerous situations when operating machinery or driving. It is important to prioritize getting quality sleep and seeking help for any underlying sleep disorders to avoid the adverse effects of sleep deprivation.
In summary, while some claim that training the mind to use less sleep is possible, it is not supported by scientific evidence. Sleep deprivation has significant negative consequences, and it is crucial to prioritize getting adequate rest to maintain overall health and well-being.

The myth of polyphasic sleep
While it is possible to train your mind to use less sleep, the concept of polyphasic sleep—which involves breaking up sleep into multiple shorter periods throughout the day—is largely a myth.
Polyphasic sleep schedules are not the norm for most humans, who usually engage in monophasic sleep, or one large block of sleep each day. While anyone can adopt a polyphasic sleep schedule, research on its efficacy is very limited, and there is no evidence that it is more beneficial than monophasic sleep.
Polyphasic sleep schedules are marked by multiple intervals of sleep and wakefulness throughout the day. Some popular polyphasic sleep schedules include the Uberman, which consists of six 20-minute naps totalling two hours of sleep per day, and the Everyman, which includes three hours of sleep at night supplemented with three 20-minute naps during the day, totalling four hours of sleep per day.
Proponents of polyphasic sleep claim that it increases productivity, alertness, and the ability to learn and retain information. However, these claims are based on anecdotal reports, and there is a lack of credible evidence to support them. In fact, research suggests that polyphasic sleep schedules can lead to adverse physical and mental health outcomes and impaired performance.
While you can train your body to need less sleep, it is important to note that chronically getting less sleep will make you more vulnerable to performing poorly. Instead of focusing on reducing sleep, it is recommended to prioritize quality sleep and make better use of your waking hours to thrive on less sleep.

Genetic factors influencing sleep
While there are suggestions and tips online about training your mind to use less sleep, there is currently no scientific evidence to support this idea. Sleep studies have shown that the more sleep debt you accumulate, the more vulnerable you become to subsequent sleep loss.
Now, on to the genetic factors influencing sleep.
Genetics plays a significant role in determining an individual's sleep patterns and duration. The amount of sleep a person needs, as well as their preference for waking early or staying up late, is influenced by their genetics. This is similar to how other characteristics, such as eye or hair colour, are determined. For example, people with a slight genetic variation in one or more genes are much more vulnerable to the adverse effects of sleep loss. Additionally, certain sleep disorders, such as insomnia, have been found to have a genetic component, with women being more likely to experience insomnia than men due to genetic factors. Large genome-wide association studies (GWAS) have identified numerous genetic associations with insomnia, including those related to sleep quality, duration, and timing.
Furthermore, the circadian sleep-wake cycle, which regulates the timing of functions such as appetite, hormone release, and metabolism, is influenced by genetics. This is evident in conditions such as advanced sleep phase syndrome (ASPS), where people feel the need to go to bed very early and wake up early, often resulting in chronic sleep deprivation due to social obligations.
Additionally, other sleep disorders, such as obstructive sleep apnea (OSA) and restless legs syndrome (RLS), have been found to have genetic influences. For OSA, while there is likely not a single genetic predisposition due to its complexity, several traits are likely influenced by genetics, such as anatomy and ventilatory control. In the case of RLS, recent genome-wide association studies have identified single nucleotide polymorphisms linked to the disorder, although functional correlations have not yet been established.
In summary, genetics plays a crucial role in influencing sleep patterns, duration, and various sleep disorders. While the exact mechanisms are still being studied, it is clear that genetics has a significant impact on an individual's sleep.

Optimising sleep quality
While it may be tempting to cut down on sleep to maximise productivity, it is important to remember that sleep is not a waste of time. Sleep allows your body and mind to function at their best during waking hours. Most adults need between 7 and 9 hours of sleep a night. Less than that, and you may experience negative effects of sleep deprivation, such as irritability, a weakened immune system, and memory loss.
That being said, there are ways to optimise your sleep quality to make the most of the sleep you get. Here are some tips to improve your sleep quality:
- Exercise in the afternoon: Raising your body temperature with exercise and then allowing it to cool down by bedtime will help you fall asleep more quickly and sleep more deeply.
- Avoid large meals late in the evening: Large meals close to bedtime can disrupt your sleep.
- Address your worries before bed: Setting aside time to think about your worries before bed can help you avoid going to sleep stressed.
- Avoid screens before bed: The blue light emitted by electronic devices inhibits the release of melatonin, a hormone that induces sleep. E-ink e-readers like the Kindle Paperwhite are an exception.
- Limit alcohol and caffeine: Alcohol can disrupt your sleep and cause grogginess the next morning. Caffeine can also keep you awake, so it's best to avoid it after 3 pm or at least 6 hours before bedtime.
- Optimise your sleep environment: About an hour before bedtime, dim the lights and transition to a restful atmosphere in your bedroom.
- Maintain a consistent sleep schedule: Set your alarm for the same time every morning, even on weekends.
While it may be possible to gradually reduce your sleep to 6 hours a night, plus a short nap during the day, it is important to listen to your body. If you feel sleepy during the day, you likely need more than 6 hours of sleep. Sleep deficiency has been linked to physical health problems and cognitive impairment, so it is crucial to prioritise quality sleep.

Sleep hacks for more efficient rest
While it may be tempting to cut down on sleep when you have a busy schedule, sleep deprivation can lead to negative effects such as irritability, weakened immune system, and memory loss. It is also linked to more severe physical health problems, such as obesity, high blood pressure, and heart disease.
Some people are genetically predisposed to be "short sleepers", requiring only 4 to 6 hours of sleep due to a mutated hDEC2 gene. However, for those not in this category, attempting to significantly reduce sleep can lead to impaired cognitive performance and reaction times, similar to the effects of alcohol intoxication.
- Gradual adjustment: If you want to reduce your sleep hours, it is recommended to do so gradually. Start by setting a consistent wake-up time every day, including weekends. Then, gradually delay your bedtime by 15-20 minutes each week until you reach your desired sleep duration. This approach gives your body time to adjust and reduces the risk of sleep deprivation.
- Quality over quantity: Focus on improving your sleep quality rather than solely reducing the quantity. Ensure your bedroom is cozy and restful, dim the lights an hour before bedtime, and establish a relaxing bedtime routine to help you wind down.
- Daily exercise: Engaging in afternoon exercises can help raise and regulate your body temperature, making it easier to fall asleep and improving sleep quality.
- Avoid large meals and alcohol before bedtime: Late-night large meals can disrupt your sleep. Similarly, alcohol may help you fall asleep faster, but it can also lead to disrupted sleep and dehydration, affecting your overall sleep quality.
- Limit caffeine intake: Caffeine can stay in your system for up to 6 hours. Avoid consuming caffeine after 3 pm or at least 6 hours before your desired bedtime to prevent it from interfering with your sleep.
- Address insomnia: If you consistently struggle with falling or staying asleep, consider seeking help for potential insomnia. Lifestyle changes may not be sufficient to improve your sleep quality, and a doctor can provide guidance or treatment options.
Remember, while optimizing your sleep habits can help you feel more rested, it is essential to prioritize getting sufficient sleep based on your individual needs. Most adults require 7 to 9 hours of sleep, and reducing sleep significantly below this range can have detrimental effects on your health and well-being.
