【智能手表植入物:追踪大象的睡眠模式以帮助人类改进睡眠】日前,科学家希望使用活动监测器研究动物睡眠,以期改善人类睡眠。来自金山大学Paul Manger教授和他的同事们正在使用Actiwatch跟踪器研究博茨瓦纳的大象睡眠模式。他们去掉手表的带子,用电子胶带和蜡将其隔离,然后连接到大象的鼻子上。通过记录器和GPS套环,研究人员发现大象每天平均睡两小时,大多数时间站着睡,每三四天才躺着睡一个小时,这可能是他们能够进入REM睡眠的唯一时间。Manger表示,了解不同动物的睡眠很重要,有望从中找到提升人类睡眠质量的办法。http://www.looooker.com/archives/41730

Smartwatch implants help track elephant sleep patterns

q-100

Humans are obsessed with sleep. We've not getting enough of it, and the tech world is flooded with wearables that confirm this fact. Now, scientists hope using activity monitors to study how and why animals sleep will help us get a better night's rest.

Professor Paul Manger from Wits University and his colleagues are using a tracker called an Actiwatch to study elephant sleep patterns in Botswana. They removed the watches' bands, insulated them with electrical tape and biologically inert wax, then attached them to the elephants' trunks. The trunk is the most mobile appendage, Manger said, and if it's still for more than five minutes it's reasonable to assume the animal is asleep.

Using the loggers and GPS collars, researchers found the elephants slept for two hours per day on average. They slept standing up most of the time, only lying down for about an hour every three or four days. This is likely the only time they were able to go into REM sleep, which means elephants possibly don't dream on a daily basis. The team also discovered the pachyderms could go without snoozing for up to 48 hours when disturbed by predators or poachers. Instead, they'd walk up to 18 miles away from the disturbance, giving up a night's sleep to avoid danger.

Previous behavioral research found zoo elephants can sleep for around four hours per day, either standing or lying down. If this new study is confirmed, wild elephants will have the shortest-known sleep time of any land mammal.

"Understanding how different animals sleep is important for two reasons," Manger told Phys.org. "First, it helps us to understand the animals themselves and discover new information that may aid the development of better management and conservation strategies, and, second, knowing how different animals sleep and why they do so in their own particular way, helps us to understand how humans sleep, why we do, and how we might get a better night's sleep."
