Scientists fear rising energy bills may lead to an increase in obesity after discovering a link between poorly-heated homes and higher body fat.
Researchers from the University of Stirling’s Behavioral Science Centre 51 to explore claims that warm indoor temperatures have 52 increasing obesity levels in winter. Instead, the team found that people who live in 53 homes are more likely to have low body mass index (BMI) levels while those who keep their heating 54 or off tend to be heavier.
Dr Michael Daly, behavioral scientist and senior lecturer, said: “We come on to investigate the scientific claims that cooler indoor temperatures help us to 55 ahealthy weight by pushing our bodies to consume more 56 through shivering and generating heat through tissues.” In fact, the research suggests people may eat less and
57 more energy when living in a warmer indoor environment.
The 13-year study, published in the journal Obesity, 58 more than 100,000 adults across England. Researchers found 59 weight levels among people living in homes heated to above 23°C (73F), which accounted for about 15,000 of the households studied.
Dr Daly said: “As national gas bills continue to rise faster than the rate of inflation (通货膨胀), this research suggests the 60 of obesity could worsen where heating dropped below 61 levels or off for lengthy periods to cut costs.
“This is not just about people who live in warm enough homes being in the 62
position to afford more expensive low-calorie foods, exercise classes and sporting activities. 63 , they find it easier to stay at a low BMI level. The study took age, gender, social class and other factors into account.
“The comfortable surrounding temperature of 20.3-23°C is where we feel comfortable in our 64 and are neither hot nor cold. At temperatures above this, we consume more energy and we eat less because our 65 is taken away.”
