Scientists have discovered why women tend to fall asleep while watching films.
"We're tired. We lead busy lives, we don't get enough sleep and we're usually trying to stay up later on weekends. So when we get cozy on the couch in front of the TV, we relax and get sleepy," Foxnews.com quoted Janet Kennedy, who runs NYCSleepDoctor.com, as saying.
Advertisement"If you're sleep-deprived, you'll get drowsy earlier than others do," added neurologist David Duhon at the Sleep Disorders Center of Central Texas.
Studies say that women more sleep-deprived and more susceptible to conditioned response than men.
On a 10-point "fatigue scale," 78 percent of women and 73 percent of men in one study checked at least one item; twice as many women as men checked all 10.
However, Kennedy countered, "There are plenty of men who conk out when the TV goes on."
Kennedy also suggested skipping alcohol.
"If both partners are drinking the same amount over dinner and then sitting down to watch a movie, the alcohol will affect the woman more," he said.
"Start the movie earlier in the evening. If you got up early and worked a tough day, it will be hard to stay up later than usual to watch a movie. Watching on Saturday instead of Friday can also help if you tend to sleep later on Saturdays... If you find yourself nodding off, pause the movie and stretch or drink a cold glass of water. And don't watch a movie lying down," he said.
