“I firmly believe that if we look to the future, if we look back, what is Apple’s greatest contribution? I think it will be in the area of physical and mental health.”
That’s what Apple CEO Tim Cook said in an interview with foreign media a few days ago. In the context of this year, more and more people are aware of the importance of physical health, and the use of technology to change life, so that people can manage their own bodies in a more intelligent way, has become a more realistic innovation in the eyes of many people.
Among them, Apple Watch, as the most crucial link in Apple’s ecosystem, is playing a vital role. In the past, watches were only tools to help people keep track of the time at any time, but now smartwatches such as Apple Watch and various sensors are shining in the field of sports and health monitoring, becoming a necessity for more people.
Why smartwatches could be a new monitoring device?
The answer is simple: The watch is the only wearable device that can stick to the body for a long time. And compared with some medical tools, wearing a smartwatch doesn’t affect our daily life and even has extra accessories. For example, since its debut, Apple Watch has satisfied the needs of different consumers through different materials such as aluminum alloy, stainless steel and 18-karat gold.
Compared with traditional watches, smartwatches have many sensors inside them, which make the decorations on the wrist more “smart”. An optical heart rate sensor on the back can monitor the heart rate in real time and present the data on the Watch face. Internal acceleration sensors can also automatically monitor the situation, for example by alerting us to the appropriate training mode when we detect movement or providing emergency assistance in the event of an accidental fall.
Wear Apple Watch
Through the data collected by multiple sensors, Apple Watch can help us provide more valuable information, and we can understand our physical state through these visual data. The addition of more sensors to measure more body data has also been at the center of the Apple Watch’s hardware upgrades over the years. In the new Apple Watch Series 6, Apple has introduced a new blood oxygen sensor to ensure that we can understand our body’s blood oxygen levels.
Of course, with existing sensors, there is still a lot of measurement data worth mining. With watchOS 7.2, Apple has given us a whole new measure of aerobic fitness. After upgrading to the new system, the Apple Watch can measure our VO2 Max at any time, and then present the cardiopulmonary function in the form of data. Apple Watch will judge the state of our cardiopulmonary function according to different ages and genders, and present it in the health app of iPhone in four categories: “high”, “above average”, “below average” or “low”. If our heart and lung function is at “low” levels, we receive not only tips but also advice on how to improve our heart and lung function and talk to our doctors.
It is understood that maximum oxygen uptake (VO2 Max) is a measure of the level of cardiopulmonary function, is also an important prediction of the overall health of the human body. It refers to the amount of oxygen the body can take in during maximum exercise. Since people need oxygen to participate in energy metabolism during exercise, the stronger the amount of exercise requires more oxygen, and the maximum oxygen uptake can reflect the use of oxygen by the human body, and judge the cardiopulmonary fitness of the human body.
In fact, the unupgraded Apple Watch can also measure our VO2 Max, and watchOS 7.2 will further expand the Apple Watch’s ability to detect vo2 Max. In the past, VO2 Max could only be measured under certain scenarios, but now we can measure vo2 Max information during our daily walk as long as we wear an Apple Watch and know what state our body is in.
