Lack of Sleep Reduces Calories

Lack of Sleep energy lostStaying up all night turns out to spend as much energy as walking along 1.6 kilometers. The comparison could be said in different ways. Staying up all night means losing 135 calories, equivalent from which is obtained from a stack of bread or with semi-skimmed milk 227 grams.

“As the amount of stored energy seem small, it is far from what we expected,” said Professor Kenneth Wright, writer and director of research at Colorado University’s Sleep and Chronobiology Laboratory. Wright and his colleagues reported their findings in The Journal of Physiology, according to Healthday.

The study involved seven adults who’s sleep patterns were observed when undergoing a diet to maintain body weight. At the first day they get enough sleep for eight hours. Then on day two and three, they made sleep deprivation, which totals 40 hours, which is then restored again with enough sleep for eight hours. Researchers found, within 24 hours of sleep deprivation that the study participants lost seven per cent more energy than when they get enough sleep.

Wright and his colleagues concluded that sleep-wake cycles normally associated with the type of energy use by the body. So that pressing the body for sleep deprivation is like reducing energy. But on the other other hand the results of this study raises another question, why don’t the body store more energy while sleeping?

“There is another function of sleep which is is important and uses energy,” said Wright. “A number of existing energy is redistribution for an important physiological processes, such as learning, memory consolidation and immune function, synthesis and release of hormones.”

But Wright reminded the reduction of sleep should not be used as a way to lose weight. Because some previous studies have confirmed that lack of sleep could also cause cognitive impairment and even weight gain as well.
