A heat dome, described as a high-pressure system trapping warm air like a lid on a pot, is impacting the eastern U.S., affecting nearly 160 million people. Temperatures are soaring above 95 degrees in many areas, with heat index values exceeding 100 degrees. This prolonged heatwave, linked to climate change, poses health risks, especially for vulnerable populations. Experts advise taking breaks, staying hydrated, and using sun protection. Similar heat domes have recently affected other regions of the U.S. and globally, highlighting the increasing frequency and intensity of extreme heat events.
