As experts, we always recommend a full-on waterproof alert device. We mentioned before that most falls happen in the bathtub or shower, so you should think of the bathroom as a hot-spot for medical emergencies. Now, if you go with a water-resistant pendant (or another wearable), it won’t function when submerged or exposed to heavy water use. A waterproof help button, on the other hand, will keep you protected even when submerged. So it’s easy to see the advantage of waterproof alert systems. That said, it’s best to check with the manufacturer to clarify the capabilities of their medical devices before deciding on which one is right for you.
