Young Adults at Higher Risk of Heat-Related Deaths in Mexico: Study Reveals Surprising Findings

A recent study has shed light on the impact of heat stress on agriculture workers in greenhouses in Jalisco, Mexico. The study, titled “Heat disproportionately kills young people: Evidence from wet-bulb temperature in Mexico,” was published in the journal Science Advances and conducted by researchers from Columbia Climate School.

The study found that 75 percent of heat-related deaths in Mexico occur among people under the age of 35, rather than in older individuals as expected. This surprising statistic has raised concerns about the vulnerability of younger adults to heat stress, particularly those engaged in outdoor labor such as construction and farming.

According to the researchers, between 1998 and 2019, approximately 3,300 people died annually from exposure to heat in Mexico. Alarmingly, nearly a third of these deaths were individuals aged 18 to 35, a demographic that is typically considered to be more resilient to extreme temperatures.

The study also highlighted the vulnerability of children under the age of five, especially infants, to heat-related illnesses. Conversely, the least number of heat-related deaths occurred in individuals aged 50 to 70.

One of the co-lead authors of the study, R. Daniel Bressler, emphasized that as the climate continues to warm, heat-related deaths are projected to increase, with young people bearing the brunt of the impact. Factors such as outdoor labor, lack of air conditioning in indoor workplaces, and participation in strenuous outdoor sports contribute to the heightened risk faced by younger adults.

The researchers noted that while most temperature-related deaths in Mexico are currently due to cold weather, the trend is expected to shift towards heat-related fatalities, particularly among younger individuals. Climate change adaptation strategies will play a crucial role in mitigating the health risks associated with rising temperatures.

In conclusion, the study underscores the urgent need for targeted interventions to protect agriculture workers and other vulnerable populations from the adverse effects of heat stress in greenhouses and other outdoor settings. By addressing the unique challenges faced by younger adults in coping with extreme heat, policymakers and stakeholders can work towards creating safer and more resilient working environments for all individuals.
