A recent study has revealed that extreme heat leads to an increase in hospitalizations due to drug and alcohol abuse. This could be a severely underestimated consequence of climate change. The study, conducted by scientists at Columbia University, is the first comprehensive investigation into the possible links between temperature and hospitalizations related to alcohol and substance abuse. According to the authors, hospitalizations for these issues increase significantly during periods of higher temperatures.
The study examined the relationship between heatwaves and hospitalizations related to alcohol and other drugs, including cannabis, cocaine, opioids, and sedatives. The scientists used data from the past 20 years, linking records of hospitalizations for alcohol and substance-related disorders with temperature and relative humidity records. The statistical model showed a direct relationship between rising temperatures and hospitalizations due to alcohol-related disorders.
The increase in hospitalizations during higher temperatures could be due to spending more time outdoors, engaging in riskier activities, increased consumption in pleasant outdoor settings, increased sweating, or driving under the influence. Higher temperatures also led to more hospitalizations for drug-related disorders, but only up to a limit of 18.8 degrees Celsius. This suggests that people are less likely to go outside at even higher temperatures.
The authors note that their study may underestimate the link between temperature increase and substance abuse disorders, as the most severe disorders may lead to death before hospitalization is possible. This study highlights the need for further research into the mental health consequences of climate change and the importance of addressing this issue in public health policies.
