Research suggests that the behavior of looking at the clock while trying to fall asleep intensifies insomnia symptoms and increases the use of sleep aids. The study, which looked at around 5,000 patients at a sleep clinic, found that time-watching behavior triggers a cycle of worrying about not getting enough sleep, leading to increased stress and difficulty falling asleep. . As a result, individuals are more likely to resort to sleeping pills in an attempt to regain control of their sleep. A simple behavioral intervention, avoiding checking the time, could help manage insomnia more effectively.
Indiana University research led by Spencer Dawson reveals that looking at the clock while trying to sleep worsens insomnia and increases the use of sleeping pills. The study suggests that avoiding checking the clock could be a simple and effective solution to managing insomnia.
Looking at the clock while trying to fall asleep exacerbates insomnia and the use of sleep aids, according to a study by an Indiana University professor – and a small change could help people sleep better.
The research, led by Spencer Dawson, clinical assistant professor and associate director of clinical training in the Department of Psychological and Brain Sciences at the College of Arts and Sciences, focuses on a sample of nearly 5,000 patients presenting for care in a sleep clinic.

“We found that time-watching behavior primarily has an effect on sleeping pill use because it exacerbates symptoms of insomnia,” Dawson said. “People worry about not getting enough sleep, then they start estimating how long it will take them to go back to sleep and when they need to get up. It’s not the kind of activity that helps make it easier to fall asleep – the more stressed you are, the harder it will be to fall asleep.
As frustration with insomnia increases, people are more likely to use sleeping pills in an attempt to control their sleep.

Dawson said research indicates that a simple behavioral intervention could help people struggling with insomnia. He gives the same advice to every new patient when they first meet.
“One thing people might do is turn around or cover their clock, ditch the smartwatch, put the phone away so they just don’t check the time,” Dawson said. “There is no place where looking at the clock is particularly useful.”
