There are certain groups of people who are at increased risk for the development of insomnia in comparison to others. It has already been noted that people who are experiencing stressful situations or medical conditions such as depression or those that cause physical discomfort or pain are more at risk to developing insomnia.
Individuals who have very irregular sleep wake schedules are at risk for developing insomnia because irregular sleep-wake schedules weaken the signals from the circadian clock regulating sleep and wakefulness. Those whose jobs involve frequent time zone changes or shift work are at particularly high risk. Other groups include:
"Night owls" who do not have a regular wake time
People who describe themselves as "worriers" are at risk for insomnia. Learning to set one's worries aside can help reduce this risk.
People who do not unwind from the day's stresses are more likely to sleep poorly.
People with genetic predisposition are also more likely to develop insomnia. While there are currently no genetic tests that can identify those at risk for insomnia, however twin studies show that genetics plays a role in insomnia.
Women are twice as likely to experience insomnia as men.
Older adults are more likely to experience insomnia.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
