Although the just past “World Sleep Day” once again reminded the public to pay attention to sleep through the theme of “healthy sleep, healthy longevity”, but looking around, sleep problems still do not attract enough attention.
It may sound surprising, but data from the World Health Organization in 2018 showed that 27% of the world suffers from sleep disorders, which is more than the world’s smokers combined. In China, 300 million people are affected by insomnia, which means 1 in 4 people have poor sleep and the number is increasing. However, most of the people around us don’t think of sleep deprivation as a disease until related problems such as high blood pressure, heart disease, and obesity appear.
Sleep problems are so important, not only because it can cause many potential harm, but more importantly, for most people, the quality of sleep can never be detected with the naked eye and psychology, and once a problem occurs, it has accumulated to a certain stage. Therefore, in terms of solutions, the best way is to observe data and adjust your sleep according to the rules. Therefore, sleep monitoring services are gradually attracting attention. How technology can help us improve sleep has become the focus of today’s people.
Find the best answer
To achieve targeted control and prevention of sleep problems, the best way is to conduct professional testing in medical institutions, which includes observation and treatment from different aspects such as heart rate, respiration, and brain waves. Just like the physical examination process, all-round inspection yields the clearest results.
Unfortunately, not everyone has the ability to regularly go to professional institutions to check for sleep problems. Therefore, under the constraints of time and cost, most of the time people need a service that can provide daily data monitoring and provide sleep advice. The sleep monitoring service is thus born. From the current point of view, there are three main solutions for this type of service:
1. Smart App monitoring, various apps that record the usage time and habits of mobile phones, conduct sleep guidance and monitoring;
Second, non-wearable devices, pillows with various sensors, bedside breathing monitors and other equipment for sleep monitoring;
Third, smart wearable devices, such as smart watches/bands/rings, etc., perform data monitoring.
The first one is undoubtedly the cheapest to use, but it has certain drawbacks in terms of accuracy and practicality. Medical research has confirmed that when operating mobile phones, tablets and other devices before going to bed, the blue light emitted by the screen will affect the formation of melatonin in the human body and affect sleep. In addition, sleep is only recorded by monitoring the state of the mobile phone, which is accurate. Sex will also be greatly reduced.
Both the second and third are supported by hardware, but compared with devices such as smart pillows and bedside monitors, wearable devices such as smart bracelets/watches are significantly more flexible and sustainable for people who travel frequently . At the same time, in the latter two schemes, software services similar to those in Scheme 1 will also work together, which is more valuable than pure App services.
Therefore, the rise of smart wearable devices has brought a worthwhile route to solving sleep problems, but the question is: Compared with more professional medical equipment, how effective is this product worn on our wrists every day? How can products like smart watches/bands help us sleep better?
keep moving towards precision
The combination of wearable devices and medical research has been carried out since a very early time, including different directions such as sleep problems and heart problems. Professional wearable devices have long become indispensable products for many medical research. However, due to the higher cost and single function of professional medical wearable devices, it brings opportunities to consumer-level smart wearable devices to a certain extent.
Earlier this month, the Stanford University Center for Sleep Sciences and Medicine compared the Amazfit Arc bracelet from Huami Technology with the Actiwatch Spectrum watch from Philips in a sleep research report. , comparing the results in the 48-hour research interval, it is found that the Spearman correlation coefficient of the data obtained by Amazfit Arc and Actiwatch Spectrum is 0.94, and the complete monotonic correlation is +1, and the data of the two are highly correlated.
In this report, if the score of the professional activity recorder Actiwatch Spectrum is used as the gold standard for defining sleep and wakefulness, then the overall accuracy of Amazfit Arc is 99.0%±0.17%, and the sensitivity is 99.4%±0.19%. The specificity of the assay was 84.5% ± 1.9%. This data means that smart wearable devices are close to professional medical equipment in the health field and can be used as an important health reference in daily life.
In fact, in June 2018, the International Journal of Environmental Research and Public Health published a report on
Report on Sleep Monitoring Capabilities of Wearable Devices
As mentioned in the article, smart wearable devices already have high sensitivity due to algorithm optimization and close association with users. With the advancement of technology, such products will provide more reliable sleep measurement data, so they have significant research and practical application potential.

More accurate data is inseparable from the early exploration of smart wearable products. Overseas Fitbit introduced heart rate data into sleep monitoring algorithms in 2017, while domestic Huami Technology began to try sleep monitoring on Xiaomi Mi Band 1 in 2015. With lower prices, all-weather monitoring and a more convenient experience, smart The bracelet does provide a reference data. With the upgrade of exercise and heart rate sensors, the improvement of algorithms, and the collection of more basic user data, smart bracelets are now able to provide more reliable data in sleep monitoring.
Complete sleep monitoring service
Accurate data is the basis of intelligent analysis, and today’s smart wearable devices already have the premise to help users monitor sleep. Therefore, in order to complete their own health assessment, a series of related services around data have a feasible premise, but this also brings new challenges to hardware manufacturers.
As discussed at the beginning of this article, how to improve people’s health awareness while helping people complete data accumulation requires technology companies to provide more comprehensive and systematic services.
The analysis and service of sleep data are inseparable from algorithms and breakthroughs in professional medical research. In this regard, overseas Apple and domestic Huami have made many attempts.
Apple acquired Beddit, a sleep monitoring product company, in 2017, and launched monitoring products placed under the mattress, while focusing on heart health, it mainly cooperates with Stanford University in research. According to Bloomberg, it will be available before 2020 The watch adds native sleep monitoring function.
In contrast, as one of the world’s largest-selling smart wearable brands, Huami Technology shipped 27.5 million smartwatches and wristbands in 2018, and its progress in sleep monitoring has also been rapid. Through the acquisition of Adidas’ Physical Enterprises Inc (PEI) and Zepp and other related algorithm technologies, it has been integrated into many of its Amazfit products. The monitoring of core health data is only the first step. Huami is also cooperating with Stanford University to combine sleep monitoring data and medical services to provide more specific and feasible sleep health services through software.

Among the “Top 10 Breakthrough Technologies in the World” selected by MIT Technology Review in 2019, the wearable electrocardiograph (An ECG on your wrist) is tied with “artificial meat burger” and “smart robot”, becoming the most popular Focus on the direction of the industry. There is no doubt that smart wearable devices have the potential value of human self-knowledge and self-quantification. It is foreseeable that, with the further extension of battery life, the continuous optimization of algorithms and more professional service cooperation, the smart bracelet with 7*24 hours of personal attributes and continuous monitoring of heart rate, pulse and exercise status will become a smart bracelet. A good assistant to help more people solve sleep problems.
And basic sleep monitoring and follow-up services are just the first step. Imagine, under the traditional medical system, how hospitals and doctors can monitor users’ sleep, exercise, heart rate and other core health data on a large scale and uninterruptedly, and how can they gain insight into the general human meaning contained in these data. Statistical rules, and then prescribe the right medicine.
Recently, Apple also announced an unprecedented heart research study in cooperation with Stanford. The 8-month research cycle, covering 50 states in the United States, involved 400,000 people, and sent atrial fibrillation to 0.5% of them, or 2,000 people. Wait for risk warning. The value of wearable products to all mankind is fully demonstrated. And that’s what makes technology sexy.
