Also, regular assessments were made regarding participants' daytime function, stress and life events, and medical and mental health.Īmong the 25 percent experiencing acute insomnia, about 75 percent of subjects recovered good sleep within 12 months, while 21 percent remained poor sleepers with recurring bouts of AI, and about 6 percent developed chronic insomnia. The subjects kept a daily sleep diary for the duration of the study, allowing for a uniquely detailed level of insight into how sleep varies from day to day.

They were verified as good sleepers over the first three months of the study and assessed on a daily, weekly and monthly basis for one full year. The study specifically determines how GS transition to acute insomnia (AI), to persistent poor sleep (PPS) - i.e., recurring bouts of AI without sustained recovery or turning to chronic insomnia (CI), to chronic insomnia, and how many of those affected by AI recover.Ī total of 1,435 adults were recruited nationwide and tracked for one year during 2015-2017.

The findings, (#0359) will be presented at SLEEP 2018, the 32nd Annual Meeting of the Associated Professional Sleep Societies LLC (APSS) in Baltimore.Īlthough some studies have offered the prevalence of insomnia symptoms in large populations, to date this is the first study to offer data on transitions of good sleepers (GS) - defined as those needing fewer than 15 minutes to fall asleep and/or who spend fewer than 15 minutes awake during the night on five or more nights per week. "These findings reveal new insights about the paths that acute insomnia takes and can inform interventions that target poor sleep and help people recover sustained sufficient sleep." "Whether caused by stress, illness, medications, or other factors, poor sleep is very common," said senior author Michael Perlis, PhD, an associate professor of Psychiatry and director of the Behavioral Sleep Medicine program. Insomnia becomes chronic when it occurs at least three nights a week for more than three months. The new study offers the latest data on the prevalence of acute insomnia, which is characterized by difficulty falling asleep or staying asleep for as little as three nights per week for at least two consecutive weeks up to three months.
