If you have sleep disorders or your sleep is disturbed so often, the reliable indicator of your sleep health is not just wearing a smartwatch, but to conduct a in-home sleep study to obtain reliable and accurate readings.
This is a small device composed of axis-based motion sensing, which can track movement in all directions. Some even have a gyroscope to measure direction and rotation. Using a process called activity recording, your smart device converts your wrist movement into sleep mode.
As you can imagine, it is not always accurate and involves some guesswork in the process. That’s because activity records only track one thing-exercise. Monitoring sleep is more than just tossing and turning.
Brain waves, eye movements, and breathing are also needed to determine the difference between deep REM sleep and light sleep. For instant, reading a book in the bed would be considered as sleep. So, can we sleep on this fact?
Although reliability is questionable, fitness trackers can be a useful guide. Numerous studies have varied results on the reliability of fitness trackers, but in most cases, the consensus is that activity recorders are usually accurate enough to track the sleep of healthy adults with normal sleep patterns. It is not as accurate as home sleep studies that use polysomnography to monitor brain activity.
Before the invention of wearable technology, it is well known that tracking anything related to your health can give you a better understanding of your choices. When you count the number of steps, you tend to do more steps. When you write down your calories, you tend to pay more attention to what you are eating.
Tracking can also help you stick to your health goals or resolutions.
Tracking is not just focusing on a big health goal, such as losing 10 kilograms, but providing you with small daily goals for improving your health.
When the goal is broken down into smaller pieces, you will feel more successful.
On the other hand, if you have a tendency to perfectionism, failing to reach the 8-hour sleep time specified by the smart device may cause more anxiety, which will affect your sleep.
