Extreme heat increases the risk of preterm births and can also lead to hospitalizations for childhood convulsions, according to new findings published by research teams at the Institute of Science Tokyo.

Meanwhile, the Japan Meteorological Agency has released its latest three-month forecast, predicting higher-than-normal average temperatures nationwide from May through July. In light of the impending summer heat, officials stress that basic safety precautions, such as staying hydrated and utilizing air conditioning, are essential.

A research team led by Shuhei Terada, an assistant professor and specialist in perinatal medicine, analyzed data from about 986,000 births registered in the Japan Society of Obstetrics and Gynecology database between 2016 and 2020.
