Study Finds Sleep Drunkenness May Affect More Than 1 in 7 People (1)

Do you get enough sleep?

Ever heard of "sleep drunkenness"? Have you ever tried to reach for your phone when your alarm clock rings? Or when you wake up you don't know where you are? Then you may have experienced what's known formally as "confusional arousal." More than 1 in 7 people in the U.S. may suffer from the condition, according to a study in the journal Neurology. In confusional arousal, sleepers wake up in a disoriented state and perhaps behave strangely in the process.

The condition often occurs when someone wakes up during non-REM sleep and can be caused by a "forced awakening" the study authors wrote. It can potentially cause violent behavior during sleep or right as the person wakes up.

To find out how prevalent sleep drunkenness is, the researchers surveyed 19,136 people age 18 or older in 15 states. They found that 15.2 percent of respondents said they had experienced a confusional arousal in the previous year. The episodes were overwhelmingly linked to sleep disorders, which were present 70.8 percent of the time.
