Can Temple track brain health? Why doctors are sceptical of Deepinder Goyal’s wearable device

The actual content of the Firstpost article wasn't accessible for this piece, so here's what we can work with: the headline tells us Zomato founder Deepinder Goyal has launched or promoted a wearable device called "Temple" that claims to track brain health, and that doctors are reportedly skeptical of its capabilities. Beyond that, we don't have confirmed details on how the device works, what sensors it uses, or the specific medical concerns being raised — so take the following as general context rather than a full breakdown of the story.

Why wearables raise EMF questions for families

Any wearable that claims to monitor brain activity likely relies on some combination of sensors and wireless connectivity — think Bluetooth or similar short-range radiofrequency signals — to sync data to a phone or app. For health-conscious parents, that raises two separate but related questions: does the device actually do what it claims medically, and is a gadget worn close to the head or body all day adding to your family's everyday EMF exposure?

It's worth noting that distance is your friend here — EMF exposure from any wireless device drops off significantly the farther it is from your body, which is why many parents choose to charge wearables across the room overnight rather than under a pillow, and opt for airplane mode when continuous tracking isn't needed.

What this means if you're building a low-EMF household

Whether or not Temple holds up to medical scrutiny, its launch is a reminder that wearable tech is becoming a bigger part of daily life — and for families already thinking about cell tower exposure and home EMF levels, it's one more device to factor into the bigger picture. If you're already working to reduce ambient EMF at home, it often makes sense to look at the full ecosystem of devices in daily use, not just wearables. For instance, families auditing their bathrooms might look into low-EMF hair dryers as a lower-exposure swap for daily routines, while those focused on indoor air and overall home environment sometimes pair that with low-EMF air purifiers that filter without adding unnecessary wireless emissions. Homebuyers specifically concerned about nearby cell towers or dense wireless environments have also explored options like EMF shielding paint as a structural way to reduce exposure at the source.

The bigger takeaway for now: treat bold claims about brain-tracking wearables with the same healthy skepticism doctors reportedly are — and if you do bring one into your home, think about where and how it's worn, not just what it promises to measure.
