Central Heating Could Be Contributing To Obesity

What evidence did the researchers look at? The researchers looked at a range of evidence to support their argument, including: studies in rodents physiological studies in humans on NST and its relationship to heat production studies in humans on cold acclimatisation and its relationship to brown fat activity and decrease in body fat studies on the regulation of indoor temperatures and temperatures which people find comfortable In particular, they quote research from Japan that they say found a decrease in body fat after people spent two hours per day at 17oC (62.6oF) for six weeks. The team also say their own research found that people get used to the cold over time. After six hours a day at 15oC (59oF) for a period of 10 days, people in a study felt more comfortable and shivered less. Importantly, as this was not a systematic review, we are unable to consider what parameters the researchers used when searching for evidence and what evidence they considered but then rejected, for whatever reason. This is why systematic reviews have more weight in terms of evidence than narrative reviews.
