Another October week feels like summer — a stark contrast to the Colorado I remember. As a medical student, I’m more aware than ever of the dangers of extreme heat. Denver reached 100 degrees six times in 2024, the third-highest since 1872. Extreme heat, defined as 90-plus degrees for two to three days or more, is becoming more common. Heat-related deaths in the U.S. rose from 1,602 in 2021 to 2,302 in 2023.

Heat disproportionately affects vulnerable groups like children, the elderly, pregnant people, outdoor workers and low-income residents. It can cause heat stroke, heart attacks, breathing problems and stillbirths. Older adults, especially those living alone without access to air conditioning, are at greater risk during heat waves.

A quarter of Denver residents with incomes below $35,000 lack effective cooling systems. Legislation has improved access to affordable, energy-efficient cooling, but more needs to be done. We must prioritize heat-vulnerable communities by increasing access to heat pumps and other efficient appliances. As a health care professional, I educate patients on staying safe, but education alone isn’t enough. Colorado leaders must address the root causes of heat-related health disparities to protect our communities.
