Before you buy a smart watch, learn about these life-saving features

The presence of smart watches is getting higher and higher, and it has the momentum to become the second portable device besides mobile phones. Just like the main function of a mobile phone is no longer just to make calls and send text messages, if you buy a smart watch just to check the time, it will be a big loss. So, what to look for when buying a smartwatch?
The functions of smart watches seem to be more and more, but basically there are two categories, sports functions and health functions. The sports function revolves around some common sports methods. The watch plays the role of recording and reminding. Whether it is a bracelet or a watch, the sports functions are basically similar, and even the motion sensors used by different brands of watches come from the same supplier.
The health function tests the research and development capabilities of manufacturers, and is also the place with the highest technological gold content on smart watches.
At present, health-related functions on smartwatches include biochemical functions such as heart rate monitoring and blood oxygen saturation detection, as well as accidental detection such as falls and impacts. Don't look at these functions that seem too conceptual, in specific use, it will really save a life at a critical moment.

Heart rate monitoring
Apple Watch has been equipped with heart rate monitoring function earlier, and many users have been saved by wearing Apple Watch, and many media have reported it many times. For example, in April 2018, Oklahoma student Skylar Joslin was in class when the watch warned of an abnormal heart rate. Joslin had previously suffered from tachycardia, so he deliberately texted the reminder to his mother.

Blood oxygen saturation detection
Blood oxygen saturation detection has been delegated to many smart watches. This function may not be commonly used in normal times, but it really showed a sense of presence during the National Day holiday that just passed.
Many users who travel to plateau areas report that when severe altitude sickness occurs, the watch shows that the blood oxygen saturation is close to 80%, while the normal number is between 95% and 100%. Many users basically adjust their travel and oxygen rhythm according to the reminder of the watch. In addition, pneumonia diseases often drop sharply with blood oxygen saturation. The United Kingdom provides oximeters to people in all high-risk areas of infection, and smart watches equipped with blood oxygen saturation detection functions have also become popular.

fall detection
There are more examples of fall detection. When the user falls, the watch will determine the user's status. If the user is unable to move, the watch will automatically send an alarm and transmit positioning information. This function can provide potential protection for elderly users and users who love cycling and other sports. A young couple hiking in New Jersey accidentally fell off a cliff. Due to the fracture and inconvenience caused by the fall, they thought they would be rescued and died. Unexpectedly, the watch automatically dialed the police to help them call rescue personnel. .

In the future, smart watches must be a health terminal, and friends who buy smart watches must see clearly before buying them.
