    You may literally have to add it to your to-do list, but scheduling a good night's sleep could be one of the smartest health priorities you set. It's not just daytime drowsiness you risk when shortchanging yourself on your seven to eight hours. Possible health consequences of getting too little or poor sleep can involve the cardiovascular, endocrine, immune, and nervous systems. In addition to letting life get in the way of good sleep, between 50 and 70 million Americans suffer from a chronic sleep disorder-insomnia or sleep apnea, say-that affects daily functioning and impinges on health. Consider the research:

    1) Less may mean more. For people who sleep under seven hours a night, the fewer zzzz's they get, the more obese they tend to be, according to a 2006 Institute of Medicine report. This may relate to the discovery that insufficient sleep appears to tip hunger hormones out of whack. Leptin, which suppresses appetite, is lowered; ghrelin, which stimulates appetite, gets a boost.

    2) You're more apt to make bad food choices. A study published this week in the Journal of Clinical Sleep Medicine found that people with obstructive sleep apnea or other severely disordered breathing while asleep ate a diet higher in cholesterol, protein, total fat, and total saturated fat. Women were especially affected.

    3) Diabetes and impaired glucose tolerance, its precursor, may become more likely. A 2005 study published in the Archives of Internal Medicine found that people getting five or fewer hours of sleep each night were 2.5 times more likely to be diabetic, while those with six hours or fewer were 1.7 times more likely.

    4) The ticker is put at risk. A 2003 study found that heart attacks were 45 percent more likely in women who slept for five or fewer hours per night than in those who got more.

    5) Blood pressure may increase. Obstructive sleep apnea, for example, has been associated with chronically elevated daytime blood pressure, and the more severe the disorder, the more significant the hypertension, suggests the 2006 IOM report. Obesity plays a role in both disorders, so losing weight can ease associated health risks.

    外貌上你年夜概不得不把睡觉当做是必必要做的事,可是晚上就寝好然则贯串毗邻康健的最明智的甲等年夜事。轻忽自欺那七八个小时的就寝,不只仅冒着白日犯困的伤害,就寝太少还年夜概风险康健,包孕导致心血管病,引起内分泌失踪调、免疫体系失踪调以及神经体系失踪调。

    为了得到精采的就寝,五到七切切的美国人正在蒙受就寝杂沓,失踪眠可能就寝梗塞,主要天天正常糊口,侵陵康健。

    思量一下下面的研究发明:

    1)睡的越少,长的越胖。据2006年科学研究院的呈报表现,每晚就寝少于七个小时的人,打呼噜的时刻少了,也就更轻易发胖。接洽到一项研究发明:就寝不敷似乎会把饥饿荷尔蒙从被抑制状况开释出来。按捺食欲的瘦蛋白淘汰,饥饿激素剧增,刺激胃口年夜开。

    2)更易选择不应该吃的食品。本周,揭晓在《临床就寝医学》上的一项研究发明,患有梗阻就寝呼吸停息可能就寝历程中其余主要呼吸杂沓的人,吃的食品中含有的胆固醇、蛋白质、全脂、饱和脂肪酸更高。女尤为云云。

    3)更易导致糖尿病和葡萄糖耐受性失踪调。2005年揭晓在《内部医学文献》上的一项研究发明,就寝不敷5个小时的人换患糖尿病的年夜概性是凡人的2.5倍,不敷6个小时的人则是1.7倍。

    4)心脏朝不保夕。2003年的一项研究发明,就寝不敷5个小时的女性患有意脏病的年夜概性是比其就寝多的人高45%.

    5)血压易升高。譬喻,据2006年《内部医学文献》呈报表现,梗阻性就寝呼吸停息已经和耐久的日期血压升高接洽起来了,就寝杂沓越主要血压越高。高血压和就寝杂沓,肥胖都是祸首罪魁,是以减肥能够淘汰一些相干的康健隐患。
