Save Energy to Burn More Calories. Decreasing the Environment Temperature to 19°C and Burn 6% More Calories at Rest
On the northern hemisphere, the days get shorter and the temperatures are falling. I hope you have not turned up your heatings, yet. It is not only the environment that may benefit from a more conscious management of the room temperature. As scientists from the Clinical Endocrinology Branch, NIDDK-NIH, Bethesda have found, reducing room temperature by 6°C (from 24°C to 19°C) will increase human energy expenditure (EE) be 6%! Exposure to 19° C resulted in an increase in plasma and urine norepinephrine levels (p<0.0001), and a 5.96 % (p<0.001) increase in energy expenditure without significant changes in spontaneous physical activity . Exposure to the lower temperature resulted in a significant increase in free fatty acid levels (p<0.01), fasting insulin levels (p<0.05), and a marginal decrease in postprandial glucose levels. A small but significant (p<0.002) increase in serum free T4 and urinary free cortisol (p<0.05) were observed at 19° C. This is of part...
