University of Georgia study on heat and alcohol use

Researchers from the University of Georgia have identified a correlation between extreme heat and increased alcohol consumption among adults aged 50 and older. The study, published in the journal JMIR Aging, analyzed over 20 years of data from more than 20,000 U.S. adults, cross-referencing longitudinal health data with weather records from the Centers for Disease Control and Prevention.

The findings indicate that each additional day with temperatures exceeding 35°C (95°F) is associated with an incremental increase in weekly alcohol consumption. This increase reaches approximately 6.3% when extreme heat persists for 30 days or more, with the most pronounced patterns occurring in individuals exposed to temperatures above 40.5°C (105°F) for extended periods.

Environmental stressors appear to interact with childhood history. Participants who reported parental substance abuse or encounters with law enforcement during childhood showed a higher tendency to drink during heatwaves. In contrast, those who reported positive relationships with their fathers were less likely to increase consumption. Lead author Hee Yun Lee noted that while drinking may be used to manage stress or heat, it can become a long-term coping mechanism that carries risks of dehydration and cardiovascular harm.
