San Francisco emergency medical workers are going to wear rings that will track their temperature and other vital signs

The Oura rings are the brainstorm of an assistant psychiatry professor:

Two weeks ago, Mason’s study on saunas and extreme heat in the treatment of depression came to a screeching halt when UCSF froze all non-essential research.

A dejected Mason texted Harpreet Rai, the CEO of Oura Health. She had purchased the Oura Rings because they were non-invasive, wearable devices that tracked body temperature. The pair discussed COVID-19 and the CEO began wondering if the ring device that records the wearer’s vital signs could help TSA agents in airports determine whether they are going to get sick.

“I told him, ‘I have no idea how to get you into an airport, but I’d like to put them on the fingers of all UCSF’s emergency staff,’” Mason recalled.

“Let’s do it!” the CEO responded.

The rings have been marketed as a sleep aid.
