Temple: Deepinder Goyal’s Experimental Health Wearable

Temple, the innovative health wearable developed by Deepinder Goyal, founder of Zomato, recently gained attention during an episode of Raj Shamani’s ‘Figuring Out’ show, which aired on January 3, 2026. Viewers were intrigued by an unusual device seen on Goyal’s temple, leading to speculation about a cutting-edge health gadget. This device, known as “Temple,” is designed to consistently monitor brain blood flow.

What is the Temple Device by Deepinder Goyal?

The Temple device represents a new frontier in health technology, emerging from companies associated with Deepinder Goyal, including Eternal, Zomato’s parent company. Goyal elaborated on the device’s capabilities, explaining that it monitors brain activity and cerebral blood flow in real-time. This information could provide crucial insights for doctors and researchers regarding brain health.

How Does the Temple Wearable Function?

Reports indicate that Temple incorporates sophisticated sensors and artificial intelligence to gather data pertaining to brain circulation. With this information, the device may shed light on aspects like cognitive behaviour, stress levels, mental fatigue, and concentration.

Temple is inspired by Goyal’s Gravity Ageing Hypothesis, which posits that gravity silently contributes to the ageing process. Over $25 million (around Rs 225 crore) has been invested by Goyal for extended research and development of this groundbreaking technology. It is suggested that humans typically remain in a vertical position—standing or sitting—thereby limiting upward blood flow to the brain. This proposed limitation may accelerate the overall ageing of the body.

According to Goyal, Temple aims to validate this hypothesis and offer deeper insights into brain functionality. While Goyal has shared teasers about the device on social media, it remains in the testing phase and is not yet available for consumer use. Nevertheless, the wearable has sparked curiosity regarding the potential significance of “brain flow” as a key health metric.
