Does a smart bracelet/watch detect sleep?

Most of the people living in metropolitan areas now have more or less sleep problems. Some of them are because of high work pressure, high mental tension, difficulty in sleeping, and not enough time for deep sleep; some are snoring because of environmental pollution. I often wake up and even affect my family's sleep. In either case, it is a wake-up call for our health. If you can find out about these problems, it's safe to say that some people just feel exhausted and do not rest when they sleep. This time, according to the doctor's statement, we changed sleep monitoring.

Sleep monitoring in the hospital can provide us with sleep breathing parameters such as EEG, ECG, eye, myoelectricity, breathing, exercise, snoring, pulse, oxygen saturation, pulse wave, respiratory rate, and posture. But going to the hospital for sleep monitoring is not an easy task for most people. Not only is it necessary to go to the hospital for leave, but also to sleep on a strange bed in a hospital with various monitoring equipment, especially during the daytime. This monitoring. And these reasons have led to a new field, that is, intelligent monitoring of sleep.

The so-called smart monitoring sleep is generally divided into three types: mobile phone APP monitoring, wearable device monitoring, non-wearable device monitoring. Are these monitoring the same as the monitoring of the hospital? Is it as reliable as the hospital? We analyze one by one.

Let's talk about mobile phone APP monitoring. The mobile phone APP monitors sleep by using the mobile phone's internal acceleration sensor and gyroscope to monitor sleeping movements, thereby analyzing sleep quality, deep sleep time, and the like. This APP will prompt you to place your phone on a bed, and then begin to record the process from lying down to sleeping, to deep sleep, and waking up according to the vibration of the bed.

This kind of APP generally says that it has functions such as monitoring sleep time, monitoring deep sleep time, recording sleep talk or snoring, and recording awake time. However, it is not difficult to find that the monitoring of the mobile phone APP is based on the principle of the sensor of the mobile phone, which senses the vibration of the bed. This is better for a single person. There is only one person on the bed.

If it is a double bed where the husband and wife sleep together, how about this vibration? In addition, there are problems such as radiation and power consumption that are monitored by the mobile phone APP. For people who are not in direct contact with the monitored person, it is less likely to monitor the pulse and blood oxygen saturation data.

Then wearable devices. The wearable device has its own acceleration sensor that can record your movements without relying on the phone. Whether you wear a wristband, watch, or ring that wears on your body and can move with your body, wearable devices can sense your movements more accurately with the built-in acceleration sensor.

When the accelerometer in the wearable device records your exercise status, you can use Bluetooth to send your data to the mobile phone and analyze it in the mobile phone APP through the personal data provided by the user, such as age. A statistic is given in APP. This statistics will contain what data depends on what hardware your wearable device supports.

For example, if your wearable device has a heart rate sensor, you can record your heartbeat changes during sleep. If you have red LEDs and infrared LEDs, you can also detect blood oxygen levels. These are all useful for your sleep monitoring and are much more accurate than mobile monitoring. And the wearable device is independent and will not affect the monitoring data by people sleeping together.

This measurement method has been much more accurate than the mobile phone, but you want to completely know how your brain wave is active when you sleep, or what the exact analysis leads you to insomnia, a bracelet is far from being able to do of.

Finally, it is a non-wearing device. Non-wearing devices are more common with smart mattresses, smart pillows, smart bed belts, and smart pillows. This intelligent hardware product, designed solely for monitoring sleep, is typically built with high-sensitivity sensors that can record the user's sleep quality, heart rate, breathing, and snoring conditions.

The user can view the software's analyzed sleep report on the phone via Bluetooth connection. At the same time, most of the smart devices that do not wear sleep monitor also have the ability to play background music that promotes sleep. In the morning, there are smart alarm clocks that allow you to wake up with less pain when you are in light sleep.

The biggest weakness of wearables is the inability to record and analyze breathing, which is the advantage of non-wearing devices. Non-wearing devices also monitor the quality of sleep for the individual's movements. Although they are placed on the bed, they are in close contact with people, making the exercise record more accurate.

But again, this kind of sleep monitoring can only achieve the effect of monitoring, although it can help you analyze deep sleep, breathing, heartbeat and other data, but can not tell you exactly where your sleep problem is. There is still a gap between sleep monitoring in the real sense of the hospital.

If you have reached a very bad state of sleep, it is recommended that you go to the hospital for regular testing. If you only want to see your own sleep quality, or if you want to supervise yourself to bed earlier, then Wearable sleep monitoring is a good choice.
