Segmented sleep, also known as biphasic sleep, is a sleep pattern where a person sleeps in two segments per day. This could look like sleeping for four or five hours at night and then taking a two or three-hour nap during the day. While this type of sleep pattern was common for our ancestors, there are mixed views on whether it is safe or healthy today. Some people report that biphasic sleep schedules work for them, making them feel more alert and productive. However, there is limited research on the health benefits or risks of segmented sleep, and it is recommended to consult a doctor before trying this sleep pattern.

Split sleep, also known as segmented sleep, involves breaking sleep into two or more shifts
The idea of segmented sleep is not new. In pre-industrial times, it was common for people to wake up for a couple of hours in the middle of the night. This practice was also observed in cultures near the equator, where residents' circadian rhythms are unaffected by seasonal changes. Today, segmented sleep still exists in some cultures, such as the siesta time in Spain or Italy, where people take a nap in the afternoon before returning to work.
Some people find that segmented sleep works well for them, allowing them to feel more alert and productive. However, there are mixed views on the health impacts of segmented sleep. While some research suggests that splitting sleep can improve cognitive function, vigilance, and mood, there are also concerns about the potential long-term effects on overall health and well-being. It is important to note that the body relies on deep sleep for various restorative functions, and breaking sleep into multiple segments may impact the quality and quantity of deep sleep.
Before adopting a segmented sleep schedule, it is recommended to consult a doctor to ensure it aligns with your health and lifestyle. It is also crucial to be mindful of warning signs that this alternative sleep schedule is not suitable for you.

Split sleep was common for our ancestors, but its health risks are unknown
Split sleep, or segmented sleep, is when you break up your sleep into two or more shifts with periods of being awake in between. This type of sleep schedule was common for our ancestors in the pre-industrial era, with people often going to sleep around 9 or 10 p.m., waking up around midnight for an hour or two, and then sleeping again until morning. This type of sleep pattern has been observed in various cultures and historical records, including medical texts, court records, and literature.
While split sleep was common in the past, its potential health risks in the present are not well understood. There is limited research on the effects of segmented sleep on overall health. Some experts argue that breaking up sleep into multiple chunks is not healthy, practical, or sustainable in today's society. Our bodies rely on deep sleep for various restorative functions, and it is unclear if segmented sleep allows for sufficient deep sleep.
The National Heart, Lung, and Blood Institute (NHLBI) warns that not getting enough deep sleep can lead to an increased risk of high blood pressure, depression, anxiety, heart disease, diabetes, and obesity. Additionally, artificial light during the waking period in the middle of the night can disrupt circadian rhythms, which are crucial for regulating various bodily processes.
However, some people naturally follow a segmented sleep pattern and feel healthy and fulfilled. Before adopting a segmented sleep schedule, it is recommended to consult a doctor to make sure it aligns with your health needs and does not negatively impact your well-being.

Split sleep may be beneficial for vigilance, working memory, and mood
Split sleep, also known as segmented sleep, involves breaking up one's sleep into two or more shifts with periods of being awake in between. This concept is not new, as it was common in pre-industrial times, and some cultures still practice it today, such as siesta time in Spain and Italy. While some people find that this sleep schedule works well for them, others argue that it is not healthy, practical, or sustainable in today's society.
There are mixed views on the safety of segmented sleep due to the lack of research on its effects on health. However, some studies have shown that split sleep may offer benefits to vigilance, working memory, and mood. One study compared the cognitive performance, subjective sleepiness, and mood of adolescent participants in 8-hour split and continuous sleep groups. The results indicated that splitting 6.5 hours of sleep with a mid-afternoon nap boosted cognitive function compared to continuous nocturnal sleep. However, when the total sleep duration increased to 8 hours, both the split and continuous sleep groups performed similarly in vigilance, working memory, and mood evaluations.
Another study examined the effects of split sleep on chronically sleep-deprived adolescents and found that a daytime nap enhanced the consolidation of material learned before sleep and improved the encoding of new information upon waking. This suggests that split sleep may benefit working memory and vigilance by providing a boost to cognitive function. However, it is important to note that the amount of REM sleep in the 8-hour split sleep group was slightly lower than in the continuous sleep group, which could impact certain functions.
While the potential benefits of split sleep on vigilance, working memory, and mood are intriguing, it is essential to consult a healthcare professional before making any significant changes to your sleep schedule. Individual differences, lifestyle factors, and potential health risks should be considered to ensure that any changes are safe and suitable for your specific circumstances.

It is recommended to consult a doctor before trying split sleep
Split sleep, also known as segmented sleep, involves breaking up one's sleep into two or more shifts with periods of being awake in between. While this was a common practice in pre-industrial times, there are mixed views on whether it is safe today. Some people find that split sleep comes naturally to them and works well for their lifestyle, while others feel better on a monophasic sleep schedule.
Before trying split sleep, it is recommended to consult a doctor so that you can make an informed plan that works for you and does not harm your health. This is especially important as there has not been extensive research on the effects of split sleep on health. Clete Kushida, MD, PhD, and medical director of the Stanford Sleep Medicine Center, highlights the many unknowns surrounding split sleep, such as its long-term safety, how it varies across individuals, and how factors like age, medical conditions, and sleep disorders may influence its effectiveness.
By consulting a doctor, you can gain a better understanding of the potential risks and benefits of split sleep for your specific circumstances. They can help you determine if this sleep schedule is a good fit for your lifestyle and health needs. For instance, if you are a shift worker, a new parent, or a student with a demanding schedule, split sleep may be a viable option to ensure you get adequate rest. However, it is important to be mindful of the potential disruption to your circadian rhythms, especially if you plan to sleep during the daytime.
Additionally, a doctor can guide you in creating a split sleep schedule that optimizes your sleep quality and ensures you obtain the recommended amount of sleep, typically close to eight hours in a 24-hour period. They can also advise you on strategies to ease into a split sleep schedule, such as starting with a short, midday nap to gradually adjust your body's sleep patterns. Remember, it is crucial to stick to the schedule once you've established one to maintain your circadian rhythm.

Split sleep may not be practical or sustainable in today's society
Split sleep, also known as segmented sleep or biphasic sleep, is when you break up your sleep into two or more shifts with periods of being awake in between. While this sleep pattern was common in pre-industrial times, it may not be practical or sustainable in today's society for several reasons.
Firstly, there is limited research on the health effects of segmented sleep. Clete Kushida, MD, PhD, and the medical director of the Stanford Sleep Medicine Center, advises against it unless there is a specific reason an individual needs to sleep that way due to the many unknowns regarding its long-term safety, suitability for different ages and populations, and potential interactions with medical conditions or sleep disorders.
Secondly, our bodies rely on deep sleep every night for essential functions such as restoration, physical recovery, memory consolidation, and bolstering the immune system. With segmented sleep, individuals may not be getting enough deep sleep, potentially compromising these critical processes.
Additionally, the modern workday, influenced by industrialization, has shaped the custom of sleeping for one continuous 6- to 8-hour segment at night. This monophasic sleep pattern is now typical of most of the population, and deviating from it may be challenging and disruptive to one's lifestyle and daily routine.
Furthermore, artificial light in the middle of the night, which is common today due to electricity and technology, could impact an individual's circadian rhythms, disrupting their internal clock that controls various bodily processes.
While some people may find that split sleep works for them, it is essential to carefully consider one's lifestyle and watch for warning signs that this alternative sleep schedule is causing harm or negatively impacting overall well-being. It is recommended to consult a doctor before making any radical changes to one's sleep schedule.
