The Critical Issue of Extreme Heat in the U.S.
Extreme heat holds the notorious title of being the deadliest weather-related phenomenon in the United States, responsible for claiming hundreds, if not thousands, of lives annually. The actual numbers might be even higher since heat factors are often not recorded on death certificates. As climate change intensifies, leading to more frequent, prolonged, and severe heatwaves, the urgency to safeguard human lives becomes increasingly evident.
Addressing this menace comprehensively would require confronting several systemic challenges. These range from combating climate change itself to correcting the disparities concerning who suffers most from heat exposure and who can afford cooling solutions. However, there are practical measures that both the private sector and government agencies could implement to prevent heat-related illnesses and fatalities. These initiatives are not only economically sensible, but they also reflect a compassionate approach to public health.
For optimal job performance, it’s essential to provide workers with the necessary protections.

Extreme temperatures can lead to serious health issues such as heat exhaustion, which includes symptoms like nausea, dizziness, and muscle cramps, and heatstroke, characterized by a core body temperature often exceeding 104 degrees Fahrenheit. Heatstroke can cause organ damage if not treated promptly and can be fatal. Vulnerable groups include the elderly, individuals with specific health conditions or those on certain medications, and people working outdoors. The latter group is exceptionally at risk as the physical nature of their work can further elevate body temperatures.
According to the U.S. Bureau of Labor Statistics, there were on average 34 heat-related worker deaths annually from 1992 to 2022, and about 3,389 instances annually of heat-related injuries and illnesses that led to missed work days from 2011 to 2022. Furthermore, a review of workers’ compensation claims in California revealed three to six times more cases of such illnesses and injuries than reported by the Bureau for that state.
Some states like California and Oregon have instituted “water, rest, shade” guidelines to protect workers. These laws mandate accessible drinking water, sufficient rest breaks, and access to shade or air-conditioned environments to help workers cool down and recuperate. The science backing these policies is robust, and where they have been enforced, they have proven effective.
The success of new regulations often hinges on the administration’s commitment to prioritize public safety.
Unfortunately, state-specific legislation results in a patchwork of protections, leaving many workers vulnerable. Experts have long advocated for a federal standard from the Occupational Safety and Health Administration (OSHA), a proposal that dates back to the agency’s creation in the 1970s. Finally, in 2024, OSHA proposed regulations requiring not just access to water, rest, and shade, but also heat safety training and acclimatization protocols for new and returning workers. The fate of these proposals under the Trump administration, however, remains uncertain.
The current administration needs to enforce this rule robustly and ensure OSHA has the resources to do so effectively. Implementing these standards would not only prevent avoidable deaths but could also enhance economic productivity, as excessive heat can impair mental and physical performance. Providing necessary protections is essential for workers to function at their best.
Some businesses resist regulations on heat health, arguing they are too costly and that individuals should take personal responsibility. However, after a worker’s death at an Oregon farm, the state enacted its heat safety law, proving most protective measures are not only affordable but vital. Heat stress is difficult for individuals to detect in themselves, and workers often skip breaks to avoid appearing unproductive, risking their health and jobs.
The proposed OSHA standard offers flexibility, allowing different implementations depending on the industry, like mobile cooling stations for farms or permanent shaded areas for oil and gas facilities. The aim is to ensure safety without burdening businesses unduly.
For businesses operating across multiple states, supporting a federal standard could simplify compliance and avoid a confusing mix of state regulations. After California strengthened its worker protection laws in 2015, there were notable improvements, largely due to better enforcement, demonstrating the benefits of clear, enforceable standards.
If the federal government fails to maintain the rule, states must be prepared to step up and provide necessary protections. Adapting existing rules like those in California or Oregon could be a straightforward solution for other states.
In regions like Texas and Florida, where laws prevent local jurisdictions from setting their own heat safety regulations, state governments must reconsider these restrictions. With rising temperatures and humidity, workers in these areas are only protected if employed by companies voluntarily implementing safety measures. Ultimately, it is the government’s responsibility to protect its citizens.
Simple cooling solutions are an economical means to ensure safety and come with the added benefit of boosting economic efficiency. As Sharon Block, a labor lawyer and Harvard Law School professor, puts it, implementing heat protection measures is both the right and the smart thing to do.
