Regular exercise is associated with less insomnia, study shows – CTV

March 27, 2024

Tired from a restless night spent awake? One of the most helpful things to do might be to get some exercise, according to a new study.

“Physically active people have a lower risk of insomnia symptoms and extreme sleep duration, both long and short,” said lead study author Dr. Erla Björnsdóttir, sleep expert and part-time teacher and researcher at Reykjavik University.

The study published Tuesday in the journal BMJ Open looked at data from more than 4,300 people ages 39 to 67 over a 10-year period.

Björnsdóttir is affiliated with a sleep application that tracks sleep and gives tips and resources for better sleep. The company didn’t fund this study, and the authors didn’t report any competing interests.

Participants in nine European countries were surveyed about their frequency, intensity and duration of physical activity as well as their symptoms of insomnia, amount of sleep each night and feelings of sleepiness during the day.
