Your fitness tracker knows: If you’re pregnant
Okay, so your fitness tracker can’t see inside your womb (yet) but one couple found out from their gadgets they were expecting. David and Ivonne Trinidad of New York City discovered the happy news after Ivonne’s FitBit showed a sharp spike in her resting heart rate that lasted for several days. At first they thought the activity tracker was broken, but someone suggested that pregnancy can raise a woman’s heart rate, as the heart must work harder to get extra blood to the uterus. So Ivonne took a test; their baby is due in November. Now, we’re not saying FitBit would make a good name for a child, but it could be a cute nickname?
Your fitness tracker knows: If you’ll die in three years
Your heart rate variability (HRV), or the variation in the intervals between your heart beats, is an important health stat that most people don’t know—but your fitness tracker may tell you. The more variation in your heart rate, the healthier you are, as researchers say it shows that your ticker is resilient and strong. Studies have shown that low HRV is linked with heart disease, metabolic syndrome, and even a higher risk of dying in the next three years.
