Why Sleepwalkers Need Regular Sleep
Sleep Deprivation May Make Sleepwalkers More Likely to Foot It
March 19, 2008 -- Sleepwalkers may want to take extra care to make sure they get enough sleep. New research shows that when sleep deprived, sleep walkers are more likely to sleepwalk.
That finding comes from a Canadian study of 40 sleepwalkers.
The study supports recommendations for sleepwalkers to \"maintain a regular sleep cycle and avoid sleep deprivation,\" write the University of Montreal's Antonio Zadra, PhD, and colleagues.
The sleepwalkers in Zadra's study spent a night at a sleep lab. They were videotaped as they slept to record any bouts of sleepwalking. Sleepwalkers typically don't sleepwalk every night.
That night, 20 people sleepwalked, and some of them did so more than once that night, for a total of 32 sleepwalking episodes.
Starting the next morning, the researchers kept participants awake for 25 hours straight to see how sleep deprivation affected the sleepwalkers.
After being awake for 25 hours, participants slept for as long as they wanted at the sleep lab. They hit the hay in the morning, so not only were they weary, they were trying to sleep at an unusual time.
During their catch-up sleep, 36 people sleepwalked for a total of 92 sleepwalking episodes.
Sleep deprivation may encourage sleepwalking in sleepwalkers, Zadra and colleagues conclude.
This study didn't include a comparison group of people who've never sleepwalked. But in their past work, Zadra's team found that healthy people with no history of sleepwalking weren't more likely to sleepwalk when sleep deprived.
The new study appears in the March edition of the Annals of Neurology.
缺乏睡眠可能使梦游者更易发生梦游事件
2008年3月19日，梦游者应该格外小心保证充足的睡眠。新的研究显示当缺乏睡眠的时候，梦游患者发生梦游情况的可能性更大。
这一结论是由加拿大一项包括40名梦游者的研究中得出。
蒙特利尔大学的Antonio Zadra博士和他的同事写到，研究支持梦游者应该“保证规律的睡眠周期，避免缺乏睡眠”的建议。
Zadra研究中的梦游者在睡眠实验室度过了一个夜晚，用录像记录了他们睡觉时候的梦游发作。梦游者典型地不会每个夜晚都发生梦游。
那个夜晚，20人发生梦游，他们中一些人一个晚上还发生了不止一次，总共由32个梦游事件发生。
从第二天早晨开始，研究者让参与者连续25个小时不睡来看看缺乏睡眠对梦游者的影响。
在25个小时没睡之后，参与者在睡眠实验室想睡多久就睡多久。他们在早晨睡觉，所以不仅仅困倦，而且是试图在非正常的时间睡觉。
在他们补充睡眠的过程中，36为梦游者总共出现了92次梦游事件。
Zadra和同事得出缺乏睡眠可能促进了梦游者出现梦游情况的结论。
研究没有包括从未发生梦游对照组人群。但是在他们过去的研究里，Zadra小组发现没有梦游史的健康人缺乏睡眠的时候发生梦游的可能并不增加。
