Wearable health devices have become part of daily life for millions of people, helping users monitor steps, heart rate, sleep, stress levels and even blood sugar. While these gadgets can encourage healthier habits, health experts say people should use them as supportive tools rather than substitutes for medical advice or their body’s own signals.
Speaking to India Today, integrative longevity coach Luke Coutinho said wearable technology works best because it increases awareness and encourages positive lifestyle changes.

“A wearable can be a perfect wake-up call. It gives us data about how many steps we’ve walked, how much we’ve slept or how long we’ve been inactive. That awareness helps people set realistic goals and make better lifestyle choices,” he said.
The popularity of smartwatches and fitness bands has grown rapidly in recent years. According to market research firm IDC, global shipments of wearable devices continue to rise as consumers increasingly seek tools that support fitness and preventive healthcare.
Research has also found measurable benefits. Studies published in leading medical journals have shown that people using fitness trackers walk an average of 1,800 additional steps each day, equivalent to roughly 40 extra minutes of walking, compared with those who do not use wearable devices.
Devices provide valuable health insights
Modern wearables now monitor much more than physical activity.
Continuous Glucose Monitors (CGMs) allow people with diabetes to check blood sugar levels without repeated finger-prick tests. Many smartwatches can also measure heart rate, blood oxygen levels, irregular heart rhythms and blood pressure trends.
Coutinho said these insights help users understand how their daily choices affect their health.
“If a meal causes a large spike in blood sugar, you can make healthier choices next time. You can see how your sleep or workout affects your glucose levels and use that information to improve your lifestyle,” he said.

However, he stressed that wearable devices cannot replace professional medical care.
“A wearable can never replace your doctor,” Coutinho said. “In fact, sometimes the data tells us that someone needs medical attention, and we immediately refer them to a physician. The best approach is to integrate wearable data with professional medical care.”
Medical experts also note that wearable devices may occasionally produce inaccurate readings. Sleep trackers, for example, sometimes confuse quiet wakefulness with sleep, while heart rate and oxygen measurements can vary depending on movement, skin contact and device quality.
Experts warn against becoming obsessed with numbers
Health specialists also caution against relying too heavily on wearable data.
Many users develop “health anxiety” by checking sleep scores, calorie counts and heart rate repeatedly throughout the day. Instead of encouraging healthier habits, constant monitoring can create unnecessary stress.
Some people even feel their exercise has little value unless their smartwatch records it.

Coutinho believes wearable devices should remain supportive tools instead of controlling daily decisions.
“It’s always a guide. It can never be the boss,” he said. “Sometimes the device may say you’re exhausted, but you feel perfectly fine. At that point, you should also listen to your body.”
Healthcare professionals say wearable technology offers its greatest value when users combine its data with regular medical checkups, healthy eating, physical activity and adequate sleep.
As wearable devices continue evolving with artificial intelligence and advanced sensors, experts expect them to play a growing role in preventive healthcare. They also agree that no device can replace professional diagnosis, medical expertise or a person’s own understanding of how they feel.
