一项研究表明，睡眠呼吸中止综合症这个可以使人在夜间喘不过气的睡眠疾病或许与病人舌头上的脂肪量有关。Researchers dont know why fat collects on the tongue, but they do know that larger and fattier tongues are more common among overweight people, who are more likely to experience this serious sleep condition.研究职员们不了解为何脂肪会积聚在舌头上，但他们了解舌头体积大、堆积脂肪量高在超重者中更容易见到，这类人也更大概患有这种紧急的睡眠疾病。In a study of 67 people treated for sleep apnoea who had lost body weight, scans suggested it was the reduction in volume of tongue fat which prompted improvements in their sleep. The researchers say the less fat on the tongue, the less likely it is to collapse1 and block the airways3 during sleep. Sleep apnoea can affect peoples quality of life by leaving them exhausted4 and stressed during the day.一项研究察看了67位同意睡眠呼吸中止综合症治疗且体重减轻的病人，扫描图像显示，正是舌头上脂肪量的降低促进了他们的睡眠得到了改变。研究职员们表示，舌头上的脂肪越少，它在睡眠时松垮并阻塞呼吸道的可能性就越低。睡眠呼吸中止会干扰大家的生活水平，让他们在白天感到筋疲力尽，紧张焦虑。The Pennsylvania researchers say there may be many people with fatty tongues who are at risk of the condition who are not obese5. They now want to find out if some low-fat diets could specifically target fat in the tongue. Exercises for the upper airway2 to improve breathing are also being studied.宾夕法尼亚大学的研究职员表示，可能有很多舌头上脂肪量高却不肥胖的人有患这种病的危险。他们目前想查明一些低脂饮食是不是对减少舌头上的脂肪量有效。同时，为改变呼吸的上呼吸道功能练习也正在研究中。
