(Pocket-lint) - Apple over the years has positioned its Apple Watch as a health accessory - and its new "Fall Detection" feature is a prime example.

The new Apple Watch Series 4 has a multitude of sensors inside that can help it to do everything from ECGs/EKGs to detect a fall. That last bit is especially handy for the differently abled or elderly, as the watch will automatically detect if they trip and fall. If the feature is enabled, and you should stumble over, a pop-up will ask if you're OK. If you don't respond, it will blare an alarm and call emergency services for you.

The thing is, the feature is off by default, as "high impact activity" can sometimes register as a fall for some people. If you want to know more about the feature, including how to turn it on, read on.

What is Fall Detection on Apple Watch?

Apple's smartwatch - specifically the Apple Watch Series 4 - can detect what Apple described as a "significant, hard fall ". If it does, its new "Fall Detection" feature can connect you to emergency services. The watch essentially vibrates, sounds an alarm, and displays an alert. If you're not OK, you can contact emergency services from the watch or dismiss the alert by tapping "I fell, but I'm OK" or "I did not fall."

However, if for some reason you cannot respond to your Apple Watch, and you're immobile for about a minute, it will begin a 15-second countdown while vibrating and sounding a progressively louder alarm. When the countdown ends, your Apple Watch automatically contact emergency services and send a message to your emergency contacts with your location letting them know it detected a hard fall.

But, if your Apple Watch detects that you're moving, it waits for you to respond to the alert and won't automatically call emergency services.
