University of Georgia study links extreme heat to increased alcohol use

A study from the University of Georgia suggests that extreme heat and adverse childhood experiences are linked to increased alcohol consumption among adults aged 50 and older. Analyzing over 20 years of data from more than 20,000 U.S. adults, researchers linked weather records from the Centers for Disease Control and Prevention to longitudinal health data.

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

Beyond environmental factors, childhood history plays a significant role. Participants who reported parental substance abuse or encounters with law enforcement during childhood showed a higher tendency to drink during heat waves. Conversely, those who reported positive relationships with their fathers were less likely to increase consumption. Lead author Hee Yun Lee noted that while drinking may seem like a way to manage stress or heat, it can easily become a long-term coping mechanism with risks of dehydration and cardiovascular harm.
