The Taipei Times reports on new research by the Taiwan Society of Sleep Medicine.

Nearly one in two Taiwanese 65 or older has trouble sleeping at least once a week and about 25 percent of them suffer from chronic insomnia, new research by the Taiwan Society of Sleep Medicine shows.

The research found that about 50.8 percent of Taiwanese 65 and older experience difficulty falling asleep, shallow sleep or early morning waking at least once a week.

“There is likely a link between increasing age and sleep difficulties, given that the estimated prevalence of insomnia in people aged between 19 and 59 is only 19.3 percent,” society director-general Lin Chia-mo said.
