In a recent NPR story, Allison Aubrey looks at how to get the most out of the health data from wearable devices. The key takeaway is simple: your numbers become far more useful when they are interpreted alongside the context of your daily life and discussed with your doctor.
Below are key highlights from the article:
- What wearables do well. Wearables can reveal useful patterns in sleep, heart rate, and physical activity. In some cases, they can even help identify serious health issues early. Aubrey reports that a smartwatch may detect an irregular heart rhythm, a potential sign of arrhythmia that can increase stroke risk. Dr. Lucy McBride, a physician in Washington, D.C., shared one case from her practice. A patient’s Apple Watch showed his heart rate dropping dangerously low during sleep. He saw a cardiologist and got a pacemaker.
- What they miss. Not everything that matters to your health can be measured by a device. McBride says some of the most important information comes from your personal story, including stress, relationships, life circumstances, and medical history. Wearables, she notes, tend to focus on what is easiest to measure.
- Make it a team effort. Dr. Sarah Benish, a neurologist with M Health Fairview in Minnesota, helped develop informal guidance for the American Academy of Neurology, recommends reviewing wearable data with your doctor. The goal is to interpret the information together and determine whether additional testing, treatment, or lifestyle changes are needed.
Tips for getting the most from your data
Below are a few additional McBride’s tips:
- Focus on patterns, not isolated readings. McBride says a single unusual day rarely tells the whole story. A week of poor sleep following a stressful event, for example, provides much more meaningful insight.
- Add context. A spike in resting heart rate can mean different things depending on what is happening in your life. Illness, stress, travel, or intense training can all affect the numbers. As McBride puts it, “Data without context is just noise.”
- Do not let the numbers overwhelm you. Tracking can be helpful, but it should not become a source of anxiety. If constant monitoring creates more worry than insight, it may be worth checking your data less frequently. If you are unsure, discuss it with your healthcare provider.
- Bring both kinds of data. Your numbers matter, but so does your story. The most useful conversations happen when you bring both to your next appointment.
The article is less about the technology itself and more about how we use it. Wearables can provide valuable clues, but understanding what those clues mean still requires context, conversation, and professional judgment.
