Hot, humid weather linked to mental health ED visits
WEDNESDAY, August 31, 2022 (HealthDay News) — Hot, humid weather is associated with an increased risk of mental health (MD)-related emergency room visits, according to research published in the September issue of International environment.
Xinlei Deng, Ph.D., of the State University of New York at Rensselaer, and colleagues conducted a case crossover study to examine whether multiple weather factors could trigger medical-related emergency room visits using data from May to October 2017 to 2018. Solar radiation (SR), relative humidity (RH), temperature, heat index (HI) and precipitation were obtained from a monitoring system in real time.
The researchers found that SR and RH had the highest risk of DM-related ED visits with a lag of zero to nine days for each increase in the interquartile range (excess risk, 4.9 and 4.0% , respectively). A short-term risk was observed for temperature (highest excess risk with a lag of zero to two days, 3.7%). An increased risk was observed over a two-week period for HI (excess risk, 3.7–4.5%), while an inverse association was observed for hours of rain with DM (excess risk , -0.5%). In September and October, stronger associations were observed for SR, RH, temperature and HI. The greatest increase in MD was observed for the combination of high RS, RH and temperature (excessive risk, 7.49%). Investigators observed a stronger weather-MD association for psychoactive substance use, mood disorders, behavioral disorders in adults, men, Hispanics, African Americans, older adults 46 to 65 years old and Medicare patients.
“For people with mental disorders, changes in several weather factors can cause symptoms that pose serious health risks,” Deng said in a statement.
