Some Types of Physical Activity May Cause Poor Sleep
A new study finds that while activities such as walking, aerobics/calisthenics, biking, gardening, golfing, running, weight-lifting, and yoga/Pilates are associated with better sleep habits, some activities actually may harm sleep quality.
Researchers at the Perelman School of Medicine at the University of Pennsylvania (Penn) discovered activities such as household and childcare work are associated with increased cases of poor sleep habits.
The study will be presented at SLEEP 2015, the annual meeting of the Associated Professional Sleep Societies LLC.
The new study breaks down physical activity — normally associated with healthy sleep — and provides detail into activities that significantly help sleep and those that may cause people to lose sleep.
The new study, led by Michael Grandner, Ph.D., looked at data on sleep and physical activities of 429,110 adults from the 2013 Behavioral Risk Factor Surveillance System. From this data set, the Penn researchers measured whether each of 10 types of activities was associated with a typical amount of sleep, relative to both no activity and to walking.
Survey respondents were asked what type of physical activity they spent the most time doing in the past month, and also asked how much sleep they got in a typical 24-hour period. Since previous studies showed that people who get less than seven hours are at greater risk for poor health and functioning, the study evaluated whether people who reported specific activities were more likely to also report sufficient sleep.
Compared to those who reported that they did not get physical activity in the past month, all types of activity except for household/childcare were associated with a lower likelihood of insufficient sleep.
To assess whether these effects are just a result of any activity, results were compared to those who reported walking as their main source of activity.
Compared to just walking, aerobics/calisthenics, biking, gardening, golf, running, weight-lifting, and yoga/Pilates were each associated with fewer cases of insufficient sleep, and household/childcare activity was associated with higher cases of insufficient sleep.
These results were adjusted for age, sex, education level, and body mass index.
“Although previous research has shown that lack of exercise is associated with poor sleep, the results of this study were surprising,” said Grandner.
“Not only does this study show that those who get exercise simply by walking are more likely to have better sleep habits, but these effects are even stronger for more purposeful activities, such as running and yoga, and even gardening and golf.
It was also interesting that people who receive most of their activity from housework and childcare were more likely to experience insufficient sleep — we know that home and work demands are some of the main reasons people lose sleep.”
“These results are consistent with the growing scientific literature on the role of sleep in human performance,” said Grandner.
“Lab studies show that lack of sleep is associated with poor physical and mental performance, and this study shows us that this is consistent with real-world data as well.
“Since these results are correlational, more studies are needed to help us understand whether certain kinds of physical activity can actually improve or worsen sleep, and how sleep habits help or hurt a person’s ability to engage in specific types of activity.”
