睡眠太多容易得大腸直腸癌

我常在電視上講解睡眠和肥胖的關係,睡太多或睡太少都容易變胖,所以總是建議大家每天的睡眠時間最好控制6-8小時之間,這樣對減肥是最好的…

最近我看到一則報導,居然說睡眠過多可能比較容易得大腸癌?!

這是美國哈佛大學的研究,研究者發現肥胖或打鼾的人每天睡眠超過9小時,比肥胖或打鼾但是睡眠7小時左右的人得到大腸直腸癌的機率高1.4-2倍。

推測原因可能是肥胖打鼾的人較容易有睡眠呼吸中止症,血氧在睡眠時長期維持低下的狀態。低血氧對於癌細胞的生長有促進作用,血氧降低等於給癌細胞更好的生長環境,因此癌症的發生率比沒有低血氧或低血氧時間較短的人更高。

反推回來,要預防癌症或已經得癌症的人,最好讓自己的血氧維持高濃度的狀態。方法是經常呼吸新鮮空氣,適度的運動,如果可能的話買個製氧氣提高居家的氧氣濃度似乎也是一個可以考慮的選擇。

Long Sleep Duration Linked to Colorectal Cancer Posted on June 5, 2013, 6 a.m. in Cancer Sleep Long Sleep Duration Linked to Colorectal Cancer Sleep – image from Shutterstock Researchers have found a significant link between long sleep duration and colorectal cancer, particularly among people who snore or who are overweight. Xuehong Zhang, MD, ScD, instructor in the Department of Medicine at Harvard Medical School and associate epidemiologist at Brigham and Women’s Hospital in Boston and colleagues analyzed data from more than 100,000 men and women taking part in two prospective cohort studies. Results showed that people who were overweight or who were regular snorers and who reported sleeping 9-hours or more per day had approximately a 1.4 to 2-fold increased risk of developing colorectal cancer compared to overweight or regular snorers who slept for 7-hours each day. The authors believe that the association between long sleep duration and incident colorectal cancer may be explained by obstructive sleep apnea (OSA), as intermittent hypoxemia, similar to that which occurs in OSA, has been shown to promote tumor growth in animal models. “Future studies should focus on different populations and evaluate to see whether sleep duration and sleep quality is a novel risk factor for colorectal cancer and to understand the mechanisms behind this association,” concluded Zhang.
