The link between short sleep duration and obesity: We should recommend more sleep to prevent obesity联系短睡眠时间与肥胖:我们应该推荐更多的睡眠,以防止肥胖症

Soaring levels of obesity might be linked to children sleeping fewer hours at night than they used to, claims a researcher in the Archives of Disease in Childhood (BMJ Specialty Journals).各级飙升肥胖可能与儿童睡眠时间少,晚上多用,债权研究员档案馆病童年(总量专业期刊).

Dr Shahrad Taheri of the University of Bristol, blames the increasing availability of computers, mobile phones, TVs and other gadgets on the diminishing nightly quota of sleep, and suggests they should be banned from children’s bedrooms.何shahrad塔赫里的布里斯托大学,自责提供更多的电脑,手机,彩电和其他小玩意对减少配额每夜睡眠并建议他们应禁止儿童卧室. Dr Taheri cites the emerging body of research on the impacts on the body of a fall in the nightly quota of sleep, which reflects circumstances in real life, rather than sustained sleep deprivation, which tends to be more extreme.塔赫里博士濒危新兴体的影响研究对身体的一个秋天的夜晚配额睡眠,它反映的情况在现实生活中,而非持续剥夺睡眠,而更趋于极端.

This research shows that shorter sleep duration disturbs normal metabolism, which may contribute to obesity, insulin resistance, diabetes, and cardiovascular disease.这项研究显示,较短的睡眠时间,扰乱正常的新陈代谢,这可能有助于肥胖,胰岛素抵抗,糖尿病,和心血管疾病等. Even two to three nights of shortened sleep can have profound effects, the laboratory data suggest.甚至两至三夜的睡眠缩短,可以有深刻的影响,实验数据表明.

One study indicated that insufficient sleep at the age of 30 months was associated with obesity at the age of 7, suggesting that this could programme the part of the brain regulating appetite and energy expenditure, says Dr Taheri.一项研究显示,睡眠不足的年龄在30个月内与肥胖的年龄在7,并暗示这可能方案一部分的脑调节食欲和能量消耗,博士说塔赫里.

But it is also a problem for teenagers in whom the need for sleep increases during this critical developmental period, he says.但这也是一个问题少年,其中需要增加睡眠,在这个关键的发展时期,他说.

Another piece of research shows that levels of leptin, a hormone produced by fat tissue when energy stores are low, were more than 15% lower in those sleeping five hours compared with those clocking up 8.另一项研究显示,瘦素,一种荷尔蒙产生的脂肪组织时,能量低,均超过15%,低于那些睡眠五小时相比超频比去年同期增长8.

Similarly, ghrelin, a hormone released by the stomach to signal hunger was almost 15% higher in those with a five hour sleep quota.同样,生长素,激素释放的肚子饥饿信号几乎高出15%,在那些有5个小时的睡眠配额.

Sleep loss also disturbs other hormones, including insulin, cortisol (stress hormone), and growth hormone, says Dr Taheri, who adds that hormonal changes could boost the desire for carlorie rich foods.睡眠损失,还扰乱其他激素,包括胰岛素,皮质醇(应激激素),而生长激素,博士说塔赫里,他们又说,荷尔蒙变化,可刺激的欲望减重丰富的食品.

And poor sleep sets up a vicious cycle.而睡眠品质低落成立一个恶性循环. It leads to fatigue, which leads to reduced levels of physical activity….which leads to lower energy expenditure…..which leads to obesity, which itself leads to poor sleep, he adds.它导致疲劳,导致减少身体活动量斜.导致较低的能源开支,比如..导致肥胖这本身导致睡不着觉,他说.

Dr Taheri acknowledges that the mechanisms behind obesity are likely to be complex.塔赫里博士承认,背后的机制肥胖可能会相当复杂. “Sleep is probably not the only answer to the obesity pandemic, but its effect should be taken seriously, as even small changes in energy balance are beneficial,” he says."睡眠可能不是唯一的答案的肥胖流行病,但其效果,应认真因为即使是微小的改变能量平衡,有利于",他说.

“Good sleep could be promoted by removal of gadget distractions from bedrooms and restricting their use,” he suggests."良好的睡眠可以促进去除后顾之忧花招,从卧室,并限制其使用,"他说. (Courtesy of Eurekalert!, by AAAS)(礼貌eurekalert!,由212)
