Being physically fit is associated with a lower likelihood of needing a prescription for sleeping pills, indicating that good physical health may improve sleep quality.
While occasional sleep difficulties are common, a significant portion of the population, between 10-20%, experience chronic and severe sleep issues.
A study of over 34,000 adults suggests that exercise may be a more effective solution for insomnia than sleeping aids. Many individuals who experience insomnia turn to medication, but this new research suggests that physical activity may be a better alternative.
“We’ve observed that people who are in better physical condition have a lower risk of taking prescription sleeping pills,” says Linda Ernstsen, an associate professor at the Norwegian University of Science and Technology’s (NTNU) Department of Public Health and Nursing.
The results of the recent study have now been published in Mayo Clinic Proceedings.
Linked health data to prescriptions
The researchers reviewed participant data in Norway’s large Trøndelag Health Survey (The HUNT study). A total of 240 000 people from Trondheim have taken part in the survey since it began in 1984. Four survey rounds have been carried out to date.
The health survey enables researchers to follow how people’s health evolves over many years. This time they linked the HUNT data to information from the Norwegian Prescription Database. The participants in the third HUNT study (2006-08) were tracked until 1 January 2018.
“Almost 5800 of the participants received their first prescription sleep medication during the study period,” says Ernstsen.
This means that approximately 17 percent of the participants’ sleep issues were serious enough to warrant a prescription from their doctor. But the participants who were in the best condition used fewer of these prescription drugs.
Men benefit the most
“These findings suggest that being in physically fit can also help you sleep better,” Ernstsen says.
Unfortunately, the beneficial effect of exercise is stronger for men than for women. The findings show that the fittest men had a 15 percent lower risk of needing drugs for troublesome sleep issues.
“The corresponding percentage risk for the fittest women was much lower. But women who struggle with sleep can still benefit from getting in better shape,” says Ernstsen.
The extensive study follows the adult population over a long period of time. The researchers, therefore, conclude that these findings should influence the sleep advice that doctors give to their patients.
“Our findings support the idea that improving or maintaining fitness can be an effective alternative for preventing sleep problems,” says Ernstsen.
