Moderate Weekly Exercise Linked With Better Sleep Quality: Study
Getting your recommended weekly dose of exercise could do more than make you stronger and boost your heart health. A new study shows it can have benefits on your snooze quality, too.
The study, published in the journal Mental Health and Physical Activity, found that people who exercised at a moderate to vigorous level for at least 150 minutes a week had a 65 percent better sleep quality than people who exercised less.
The exercisers also felt less tired throughout the day and had fewer leg cramps while sleeping, researchers found.
"We were using the physical activity guidelines set forth for cardiovascular health, but it appears that those guidelines might have a spillover effect to other areas of health," study researcher Brad Cardinal, a professor of exercise science at Oregon State University, said in a statement. "Increasingly, the scientific evidence is encouraging as regular physical activity may serve as a non-pharmaceutical alternative to improve sleep."
The study included health data from more than 3,000 men and women between ages 18 and 85 who participated in the National Health and Nutrition Examination Survey. They wore an accelerometer on their right hip for a week after they were examined, and they were questioned on their sleepiness and quality of sleep.

Poor sleep quality has, in past research, been linked to increased inflammation (which can lead to heart disease and stroke), high blood pressure, and increased blood glucose levels and insulin resistance among people with Type 2 diabetes.
