A study published in Nature Climate Change on September 8, 2025, showed that hotter days in the United States are linked with higher sugar intake. Researchers from the United States and the United Kingdom studied how temperatures from 54 to 86 degrees Fahrenheit (12 to 30 Celsius) changed buying habits. The study found that Americans consumed over 100 million pounds (358 million kilograms) more sugar each year than 15 years earlier. Sugary drinks and frozen desserts became the predominant products purchased. The rise was stronger among families with lower income, less education, and outdoor jobs. Experts said the situation is crucial because obesity and diabetes are already persistent health concerns. They added that this pattern is widespread and has significant effects. Data from the National Oceanic and Atmospheric Administration confirmed that average U.S. temperatures increased by 2.2 degrees Fahrenheit (1.2 Celsius) since 1895.

The researchers explained that sugar use was not only about thirst but also about living conditions. Families without clean water or air conditioning were more vulnerable to this pattern. Health experts said that even one extra soda daily may raise diabetes risk by 30 percent. They called the effect adverse and warned that it may intensify with global warming. Specialists added that the pressure on poorer households is considerable, and the difference in health impact is already evident. Scientists described the results as noteworthy, impactful, and even remarkable for public health. They stressed that the link between heat and sugar intake shows a complexand lasting challenge that requires sustainable health solutions.”
