Sleep is a mysterious area of science, but it is clear that it has a significant impact on our health and wellbeing. Our 24/7 lifestyles are characterised by disrupted and insufficient sleep, and there are far-reaching implications for our health. Sleep deprivation has been linked to an increased risk of cancer, metabolic syndrome, obesity, depression, diabetes, stroke and heart attacks. Researchers are looking at ways to improve sleep quality and reduce the amount of sleep we need, but will we ever be able to remove the need for sleep altogether?

What You'll Learn
Will we ever find a 'cure' for sleep?
Sleep is a mysterious area of science with much left to discover. While the ancient Greeks valued sleep for its restorative powers, modern industrialised societies have taken a very different view. Sleep is often seen as an obstacle to productivity, with statements like 'sleep is a waste of time' and 'I'll sleep when I'm dead' becoming increasingly common.
The importance of sleep has been well-documented, with sleep deprivation linked to increased cancer and metabolic syndrome risk, a slowing of reaction time, and increases in obesity, depression, diabetes, stroke and heart attacks. Despite this, researchers are looking at ways to reduce the need for sleep in high-pressure environments such as conflict zones.
Innovations in sleep technology are advancing the measuring and understanding of sleep, with new discoveries opening the door to more effective and personalised treatments for sleep disorders and circadian misalignment. Drastic improvements in sleep quality may be possible in the future, which could lead to a slight reduction in sleep duration.
However, it is unclear if a 'cure' for sleep will ever be found or if that is even desirable. While sleep may be viewed as an obstacle in today's 'always-on' society, it is still a necessary part of our lives and will likely continue to be for centuries to come.

Will we need less sleep in the future?
While sleep is still a mysterious area of science, it is unlikely that we will need less sleep in the future. In fact, considering current work demands, it may be that we need more sleep. Data for the UK and US report an increase in sleep duration for many parts of the population.
However, researchers for the military are looking at what can be done in high-pressure environments such as conflict zones to allow as much alertness as possible to be retained on low sleep. There is also talk of finding a 'cure' for sleep.
Innovations around sleep are advancing the measuring and understanding of sleep, and new discoveries will open the door to more effective and personalised treatments for sleep disorders and circadian misalignment. For example, there are now non-invasive, contactless devices, wearables and smartphone apps that help users learn more about their sleep.
It is also possible that drastic improvements in sleep quality will be possible in the future, and with that, a slight reduction in sleep duration will be the logical consequence.

Will we need more sleep in the future?
Sleep is a mysterious area of science, with much left to discover. Our 24/7 lifestyles are characterised by disrupted and insufficient sleep, with far-reaching implications for our health and wellbeing. The harm of sleep deprivation has been well-documented – increased cancer and metabolic syndrome risk, a slowing of reaction time, it’s been linked to increases in obesity, depression, diabetes, stroke and heart attacks.
Considering current work demands, it may be that our need for sleep has increased. Data for the UK and US report an increase in sleep duration for many parts of the population. Other possible factors contributing to this include improved science communications and sleep awareness campaigns, and more interest in sleep and the benefits it brings.
Innovations around sleep are those that advance the measuring and understanding of sleep. New discoveries will open the door to more effective and personalised treatments for sleep disorders and circadian misalignment – the body clock being out of sync with the external day – as they allow for better at-home testing involving non-invasive, contactless devices, wearables and smartphone apps that help users learn more about their sleep.
It's unlikely that we will ever remove the need for sleep, but drastic improvements in sleep quality will be possible in the future, and with that, a slight reduction in sleep duration will be the logical consequence.

Will we be able to boost alertness in high-pressure environments?
While sleep is still a mysterious area of science, researchers are looking into what can be done in high-pressure environments to allow as much alertness as possible to be retained on low sleep.
Our 24/7 lifestyles are characterised by disrupted and insufficient sleep, with far-reaching implications for our health and wellbeing. The harm of sleep deprivation has been well-documented – increased cancer and metabolic syndrome risk, a slowing of reaction time, it’s been linked to increases in obesity, depression, diabetes, stroke and heart attacks.

New discoveries will open the door to more effective and personalised treatments for sleep disorders and circadian misalignment. For example, non-invasive, contactless devices, wearables and smartphone apps that help users learn more about their sleep.
It is also possible to boost brain waves during deep sleep, improving sleep quality and therefore reducing the amount of sleep needed.

Will we be able to improve sleep quality?
While sleep is still a mysterious area of science, it is clear that it is an important part of our lives. Sleep deprivation has been linked to a range of health issues, including an increased risk of cancer, metabolic syndrome, obesity, depression, diabetes, stroke and heart attacks. It also slows down our reaction time.
Despite this, researchers are looking at ways to reduce the need for sleep in high-pressure environments, such as conflict zones. However, it is unlikely that we will be able to remove the need for sleep altogether.
Innovations in sleep technology, such as measuring and understanding sleep, have already led to drastic improvements in sleep quality. For example, electrodes can be used to boost brain waves during deep sleep. As a result, it is likely that we will see a slight reduction in the duration of sleep needed in the future.
Advancements in the field of sleep will also lead to more effective and personalised treatments for sleep disorders and circadian misalignment. This will allow for better at-home testing involving non-invasive, contactless devices, wearables and smartphone apps that help users learn more about their sleep.

Frequently asked questions
While there is talk of finding a 'cure' for sleep, it is unlikely that we will ever stop needing sleep altogether. Sleep is essential for our health and wellbeing, and sleep deprivation has been linked to a number of serious health issues.
Sleep deprivation has been linked to an increased risk of cancer and metabolic syndrome, as well as a slowing of reaction time. It has also been associated with increases in obesity, depression, diabetes, stroke and heart attacks.
In certain high-pressure environments, such as conflict zones, sleep deprivation can be beneficial as it allows individuals to retain as much alertness as possible. However, the overall benefits of sleep deprivation are limited, and the risks far outweigh any potential advantages.
Researchers are working on new treatments for sleep disorders and circadian misalignment, as well as advancements in measuring and understanding sleep. Electrodes that boost brain waves during deep sleep can also improve sleep quality, leading to a slight reduction in sleep duration.
