More and more Koreans have difficulties going to sleep or experience frequent wakeful periods during the night, a study suggests.
The prevalence of insomnia among adults more than doubled from 3.1 percent in 2005 to 7.2 percent in 2013, according to a study led by Chung Seock-hoon of the Asan Medical Center and Sim Chang-sun of Ulsan University Hospital.
"Increased psychological stress, heavy workloads, alternative work schedules, and high-caffeine drink consumption also can affect insomnia," the study says.
The researchers analyzed National Health Insurance Service data from 2005-2013 and published their findings the journal Psychiatry Investigation by the Korean Neuropsychiatric Association on Tuesday.
Insomnia increases with age. One in five people over 80 or 18.2 percent suffered from insomnia as of 2013. The percentage was 15.2 percent among those in their 70s and 10.3 percent among those in their 60s.
It attributed the increase to aging and decreased physical activity as well as psychological problems such as a sense of isolation and anxiety.
Chung said, "Insomnia can be treated and cured. Patients should first visit a hospital and change their bedtime habits and relieve stress and anxiety."
