How Smartwatches Work

A smartwatch is a wearable device worn as a wristwatch. While usable as a watch, it has much of the functionality of a mobile phone condensed into a smaller package.  Certain models require a Bluetooth connection to a smartphone for full functionality, such as messaging and phone calls. Other types have independent LTE functionality using an embedded eSIM card and don't need to be paired to a smartphone.

Smartwatches typically use Google (Android), Samsung or Apple iPhone operating systems and are fully compatible with smartphones using those operating systems. You can also buy dedicated smartwatches for specific functions like navigation and fitness tracking.

How a Smartwatch Can Help Keep You Active and Safe

Certain smartwatches include fitness tracker applications that check your physical activity. Some have pedometers that count the number of steps you take each day, while others check your heart rate and other vital signs. These features let you track your daily activity and help you stay fit.

Using a smartwatch's fitness tracker function, you can track the number of steps you take against an individual target. UCLA Health recommends seniors walk at least 2,500 steps a day but adds that walking 6,000 to 8,000 steps a day has significant health benefits.

A major advantage of a smartwatch is the ability to use it to monitor your health and call for help if necessary. Because your watch is always on your arm, you don't need to find or reach for a remote alarm device in an emergency. Below are some ways your smartwatch can help keep you safe.

Fall Monitor

The fall monitor detects if you have a fall and automatically sends a message to a service provider, friend or partner. This is a valuable feature for seniors who may be at risk of falls while walking and exercising outside an independent living community. It ensures help is always at hand.

Heart and Respiratory Monitor

Certain smartwatches can check your heart rate, heart rhythm and blood oxygen levels. They send an alarm to the service provider if they detect abnormalities that might occur while you're undertaking an exercise session. Medical alert watch services usually require a subscription and monthly fee.

Emergency Response

Smartwatches have an emergency SOS function. When you activate the function, the watch sends an alert to predetermined contacts together with your GPS location. Some smartwatches send an automatic alert if they detect an accident or sudden impact, like falling off a mountain bike or having a vehicle accident.

Tips to Help You Use a Smartwatch to Meet Your Fitness Goals

Keeping fit is important, especially as your lifestyle may be more sedentary than when you were working. Choosing a smartwatch with a good fitness tracker app can help you keep track of your wellness. Features to consider include:

• Step tracker. This allows you to check how far you walk or run every day and keep track of the overall distance you've achieved over a period.
• Calories. You can keep track of the number of calories you've burned off while exercising.
• Exercise heart rate. This measures your age-related target heart rate to help gauge the intensity of your exercise.
• Customized fitness goals. You can use the app to set fitness targets such as the distance covered, number of steps and calories burned.

Features to Look for in a Smartwatch

When choosing a senior's smartwatch, look for features that make the device easy to use and read. Key smartwatch features for seniors include:

• Large, easily readable display. The watch should have a large display with clear bold text that’s bright enough to be seen outdoors. Icons should be large enough to let you easily navigate the different functions.
• Wearability. Look for an ergonomic design that's comfortable on your wrist. Check that the strap is comfortable, and make certain it's not too heavy. It's best to choose a well-known brand.
• Ease of use. Choose models with simple interfaces that let you set the watch up to suit your needs and preferences. If you're buying a Bluetooth model, make certain it's compatible with your phone.
• Voice activation. Consider buying a voice-activated smartwatch that verbally responds and reads messages and alarms.
• Long battery life. Look for a device with extended battery life to increase convenience.
• Health monitoring and reminders. Depending on your health, consider buying a smartwatch that can monitor your vital signs and provide medication reminders.
• GPS. GPS functionality is useful for activity tracking and essential if you wish to use SOS and fall monitoring features.
• Water resistance. This is a critical feature if you plan to use your watch in the rain or need to keep sweat from damaging it.

Operating system compatibility. Although smartwatch apps can work across different operating systems, you get the best functionality if you stay within the same ecosystem. If you have an Apple smartphone, it's better to get an Apple smartwatch. The same applies to Android and Samsung; ensure your smartphone and smartwatch work with the corresponding operating system.
