與狗狗共眠到底好不好?

The question: Family dogs often spend the night in their owner's bedroom. Might this affect people's sleep?

研究主題：狗狗睡在主人房間是否會影響睡眠?

In this study, the researchers assessed the sleep habits of 40 healthy adults (average age, 44) who had no sleep disorders and who had a dog older than 6 months (average age, 5 years) that slept in the bedroom.

此次研究對于40個健康的成年人的(平均年齡為44歲)，他們睡眠情況良好，并且養(yǎng)狗時間超過6個月(平均時間為5年)，平時狗狗和他們都睡在臥室。

For seven nights, the human participants wore an activity monitor on their wrist, and the dogs wore a similar device on their collar. People spent an average of 7.9 hours in bed and 6.7 hours asleep.

連續(xù)七天晚上，受試者手戴著活動監(jiān)測儀，而他們的狗狗也會在脖子上佩戴相同裝置。據(jù)觀察，這些人每天在床上的時間平均為7.9小時，其中睡眠時間為6.7小時。

Sleep efficiency was worse if the dog was on the bed rather than elsewhere in the room: 80 vs. 83 percent. People also spent less time awake after initially falling asleep if their dog was not on the bed. The dogs' sleep efficiency was not affected by their location.

據(jù)觀察，與狗狗共處一室時，人的睡眠效率為80%;而狗狗在別處時，人們的睡眠效率為83%。如果不與狗狗同床，他們進入睡眠狀態(tài)所用的時間更短。而狗狗的睡眠效率與它們睡覺場所沒有關系。

"A dog's presence in the bedroom may not be disruptive to human sleep, as was previously suspected," the researchers, all affiliated with the Mayo Clinic,reported.

梅奧醫(yī)療集團的研究成員說：“狗狗的在場對主人睡眠的影響并不如之前我們所想的那么大。”

Data came from a small number of participants for a short time. The study did not include people with more than one dog in their bedroom and did not include, for comparison, people who did not sleep with a dog in the bedroom. The findings do not apply to other pets, such as cats.

值得注意的是，本次調查的對象僅針對一小部分人，實驗周期也比較短。研究沒有包括那些在臥室里養(yǎng)多條狗的人，也未包括那些不和狗狗一起睡覺的人。本次研究結果并未推及其他寵物，比如說貓。
