Wearable tech is having a moment — and for all the right reasons. From smartwatches to implantable, these devices can predict how well you slept or whether you caught a cold that requires immediate medical attention, with haunting accuracy. This is the future of health and fitness, and Dr Shriram Nene, cardiothoracic surgeon and husband to Bollywood actor Madhuri Dixit, welcomed it with open arms. He took to Instagram to share that he ran an experiment where he wore a smart ring for 90 days straight, and learnt some key lessons:DISCLAIMER: This article is based on information from the public domain and/or the experts we spoke to.

Then 90 days of data showed me what I was missing.Late nights had a pattern.Stress had a pattern.Recovery had a pattern.“The lesson wasn’t to chase perfect scores. It was to notice the signals early enough to make better decisions. A wearable cannot diagnose you—but it can sometimes help you hear the body before it has to shout,” he mentioned in the caption of his Instagram post.
