L.A. Warns Record Humidity Is Driving More Heat Illness ER Visits

1 articles · Updated · Los Angeles Times · Sep 8

Summary

  • Los Angeles County health officials said emergency visits for heat-related illness have risen during this summer’s heat wave as record humidity makes already high temperatures feel even hotter.
  • Humidity sharply raises heat stress because sweat evaporates less easily, forcing the body to work harder to hold its core temperature near 98.6°F, UCLA public health expert David Eisenman said.
  • Officials urged residents to drink water all day, avoid the hottest hours, move to air-conditioned spaces or cooling centers, and call 211 if they need help finding a cool place.
  • 911 should be called for danger signs including confusion, fainting, hot red skin, a body temperature of 103°F or higher, a fast strong pulse, headache, dizziness or nausea.
  • The warning underscores a broader California heat-health threat that has intensified with climate change; a 2021 Times investigation counted 3,900 heat deaths in the state over a decade.
