While the North remains chilly, millions of Americans in the Southwest are under extreme heat warnings.
According to Newsweek, temperatures are reaching up to 30 degrees above average in parts of the Southwest, with some areas expected to soar well into the 100s.
Alongside these warnings, residents in southern Nevada, southern California, and Arizona are being advised to avoid coffee and other caffeinated beverages.
The reason is that caffeine can accelerate dehydration.
Newsweek also reports that people are encouraged to skip large or protein-heavy meals, as these can raise body temperature. Additionally, there is a reminder not to leave young children unattended in cars.
"This heat dome is not just early and intense — it is stubborn," Accuweather senior meteorologist Tyler Roys told Newsweek. "A multiday stretch of extreme heat significantly increases the risk of heat-related illnesses."
CBS News reported that the heatwave could persist for several days. On Tuesday, more than 60 temperature records were broken, including Palm Springs, California, reaching 103 degrees. Phoenix hit 100 degrees on Wednesday, marking the earliest such high temperature recorded in the city.
The heatwave is expected to continue through the weekend and into early next week, with record-breaking daily highs and overnight lows.
