You've heard of sleep walking, sleep talking, sleep eating but what about sleep texting?
It's a modern day sleep issue plaguing teenagers in particular because they are constantly connected to their Smartphones.
Sleep texting is when you pick up your phone during the night, send a text message and don't remember doing so when you wake up the next morning.
Doctors say the behavior can be problematic because it interferes with sleep patterns and can lead to sleep deprivation.
Dr. Ramon Cuevas, a sleep expert at Vanderbilt children's hospital, says sleep texting is a growing phenomenon.
“They're basically using their Smartphone, they're composing a message, sending it [and] sometimes even sending pictures while they're still asleep,” he explained, adding, “They'll look at it [the next day] and sort of laugh and say, 'Oh, I don't remember doing that last night.'”
While it may sound funny, but Dr. Cuevas says there are serious and sometimes disastrous consequences to sleep texting and the consequences can be particularly bad for teens' health.
“They're not able to disconnect, especially at bedtime when they should be focusing on falling asleep and going to bed,' he said.
Dr. Cuevas says kids often wake up feeling sleepy which can affect school performance and other activities.
He suggests that parents limit their kids' Smartphone use to no more than two hours a day and keep the technology out of the bedroom.
Children should get at least nine hours of sleep each night, according to experts.
