Smartwatches detect early signs of PTSD among those watching coverage of the Oct. 7 attacks in Israel

In a three‐year study involving more than 5,000 residents of Israel before and after the mass traumatic events of October 7, 2023, those who watched extensive media coverage of the attacks were found to be more likely to develop post‐traumatic stress disorder (PTSD).

Prof. Erez Shmueli and Prof. Dan Yamin of Tel Aviv University and Wizermed LTD, in collaboration with colleagues from Tel Aviv University and Stanford University, present these findings in PLOS Mental Health.

People who are directly exposed to traumatic events can develop acute stress disorder, which may progress to PTSD. Early detection and treatment can prevent the progression of PTSD.

However, less is known about PTSD among people who are indirectly exposed to traumatic events through media consumption. To address that gap, Yamin and colleagues studied the aftermath of the October 7 attacks.
