Hello, my name is Alex Elsen and thanks for reading! Today will be the first of a few blog posts about the effects of exercise on sleep. I recently found a research article composed by a University in Finland. These researchers sought to see the effects of vigorous late night exercise on sleep quality. The common view is that exercise causes arousal which will decrease sleep quality, but this has not often been scientifically tested. The subjects were 11 young adults, 7 men and 4 women, about 26 years old. The subjects were observed for two days: a day where they exercised before bed and a control night with no exercise. On the exercise day the subjects performed a 35 minute workout that ended about 2 hours before sleep time. Sleep quality was measured with both objective and subjective means. The objective means were tracking brain activity, heart activity, and sleep movement. The subjective mean was a questionnaire. The results of the study showed that vigorous exercise around 2 hours before bed did not disturb sleep quality between the two days. So, for those who say they don’t have time to workout during the day, feel free to work out really hard before bed and not worry about being able to go to sleep. Until next time try not to end up like this guy.
