Higher indoor temperatures during the winter may be contributing to rising rates of obesity in the United States and other developed countries, according to a new British study.



Reduced exposure to cold may affect the ability to maintain a healthy weight by minimizing the need for energy expenditure to stay warm, as well as reducing the body's capacity to produce heat, said the researchers.



They found that winter indoor temperatures in the United States and the United Kingdom have increased over the past few decades, which means people are spending more time in milder temperatures.
