Extreme Heat Waves in the Western U.S.: Why Some People Are Collapsing While Walking Outdoors

Residents across the Western U.S. faced a severe heat wave that brought extreme temperatures over the weekend. States like Washington, Oregon, Southern California, Nevada, and Arizona saw dangerously high readings, impacting many people’s health and safety.

In total, about 1.2 million individuals were under extreme heat alerts. Tucson, Arizona, was the most affected, with temperatures expected to reach between 102 and 107 degrees Fahrenheit (39 to 42 degrees Celsius). Inland Southern California also reported alarming conditions.

In addition, around 18.6 million people nationwide faced significant heat risks, affecting outdoor workers and those in homes without air conditioning. Miami was among the cities at risk.

Notably, Portland, Oregon, set a record high for August 22 at 102 degrees (38.9 Celsius), surpassing the previous record of 98 degrees (36.7 Celsius), set in 1942. This surge in temperatures isn’t just concerning for residents; it poses real dangers during community events, too.

During Portland’s annual Hood to Coast relay race, which stretches from Mt. Hood to the Pacific Ocean, some participants felt the heat’s effects intensely. One runner, David Loftus, fainted shortly after completing his leg of the race. He’d hydrated before running, but the heat proved overwhelming. After collapsing, he remembered being helped by a stranger just before losing consciousness. Once awake, he was taken by ambulance and spent the night under observation but ultimately made a full recovery.

As temperatures soared, calls to emergency services also increased. In one day, health officials reported 16 emergency room visits related to heat, with six of those being race participants. Brendon Haggerty from the Multnomah County Health Department stated, “This is the highest heat risk we’ve seen recently.”

Historical data shows that heat-related emergencies are becoming more common. For example, in June 2021, Portland hit a shocking high of 116 degrees (46 Celsius), leading to over 100 deaths. Most victims were seniors, highlighting the greater risks for vulnerable populations in extreme temperatures.

As weather patterns continue to change, experts warn that heat waves like this may become more frequent. They emphasize the importance of staying hydrated, seeking shade, and checking on neighbors, especially the elderly. Adapting to these conditions is crucial for safety on hot days.
