WEDNESDAY, March 27, 2024 (HealthDay News) — Folks who consistently work out two to three times a week are less likely to suffer from insomnia, a new study says.
That sort of long-term commitment to exercise also helps people get the recommended amount of sleep each night, according to findings published March 26 in the journal BMJ Open.
The paper “indicates strongly that consistency in [physical activity] might be an important factor in optimizing sleep duration and reducing the symptoms of insomnia,” concluded the research team led by Icelandic psychologists Erla Bjornsdottir and Elin Helga Thorarinsdottir.
For the study, researchers tracked the exercise habits and sleep quality of nearly 4,400 middle-aged adults from 21 hospitals in nine European countries.
Participants were specifically asked how often they exercise to the point that they become out of breath or sweaty.
Researchers found that people who persistently worked out at least a few times a week — totaling at least one hour of exercise weekly — were:
-
42% less likely to find it difficult to fall asleep
-
22% less likely to suffer any symptoms of insomnia
-
40% less likely to suffer more than one insomnia symptom
Symptoms of insomnia include taking a long time to go to sleep, waking in the night and feeling excessively sleepy during the day.
People who consistently exercised also were 55% more likely to get the normal, recommended amount of shut-eye, between 6 and 9 hours a night, researchers found.
They were 29% less likely to have short sleep less than 6 hours, and 52% less likely to have long sleep of 9 hours or more, results show.
In addition, folks who became active during the course of the decade-long study were 21% more likely to become normal sleepers than those who remained inactive.
These results jibe with other studies that have linked regular exercise with sound sleep, researchers said in a journal news release.
People who work out not only make their bodies tired enough to get good sleep, but they also are more likely to follow a healthy lifestyle, the researchers noted.
