Is It Really Bad to Share a Bed With Your Dog?
与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?
研究主题:狗狗睡在主人房间是否会影响睡眠?

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.
此次研究对于40个健康的成年人的(平均年龄为44岁),他们睡眠情况良好,并且养狗时间超过6个月(平均时间为5年),平时狗狗和他们都睡在卧室。

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.
连续七天晚上,受试者手戴着活动监测仪,而他们的狗狗也会在脖子上佩戴相同装置。据观察,这些人每天在床上的时间平均为7.9小时,其中睡眠时间为6.7小时。

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.
据观察,与狗狗共处一室时,人的睡眠效率为80%;而狗狗在别处时,人们的睡眠效率为83%。如果不与狗狗同床,他们进入睡眠状态所用的时间更短。而狗狗的睡眠效率与它们睡觉场所没有关系。

"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.
梅奥医疗集团的研究成员说:“狗狗的在场对主人睡眠的影响并不如之前我们所想的那么大。”

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,本次调查的对象仅针对一小部分人,实验周期也比较短。研究没有包括那些在卧室里养多条狗的人,也未包括那些不和狗狗一起睡觉的人。本次研究结果并未推及其他宠物,比如说猫。
