TOKYO, March 15 (Bernama-Kyodo) -- A team of scientists at a Japanese university has found that the risk of stroke rises after a typhoon passes, apparently because of a sharp drop in air pressure, Kyodo News reported.
The team at the Institute of Science Tokyo said the finding suggests that the likelihood of strokes may increase as typhoons become more powerful due to climate change.
The researchers analysed 850,294 emergency stroke admissions that occurred between May and October over an 11-year period ending in 2021, when many typhoons hit Japan, tallying the risk of stroke in the six days following the arrival of typhoons with winds of 54 kilometres per hour or higher.
According to the team’s research published in the Nov 5, 2025, issue of the academic journal Environment International, the risk was 1.05 times higher than during periods without typhoons, and the increase was greater between the second and fifth days.
“We need to raise public awareness of the risk of typhoon-caused strokes and how best to respond,” said Hisaaki Nishimura, an assistant professor who led the team.
