Exercising before sleep does not guarantee restful sleep

Intense workouts before bed don't necessarily lead to restful sleep, a recent study from Concordia University found.

Thus, according to the study conducted by Emmanuel Frimpong, postdoctoral researcher at the Sleep, Cognition and Neuroimaging Laboratory, and Melodee Mograss, cognitive neuropsychologist and researcher at the PERFORM Sleep Laboratory, intensive training does not promote sleep if it is performed less than two hours before bedtime.

The opposite, however, is observed if it is performed two or more hours before sinking into the arms of Morpheus.

"Based on our analysis, for healthy young and middle-aged adults with no history of sleep disturbances, exercises performed in the evening should be performed in the early evening if possible," Frimpong concluded. . The latter added, on the other hand, that a regular exercise schedule must be established so as not to disturb sleep.

“Finally, sleep hygiene strategies should also be adopted, such as taking a shower between the end of the exercise session and bedtime and avoiding heavy meals or drinking plenty of water before bedtime. 'go to sleep,' he also said.

Research based on 15 previous studies

While the results seemed mixed on the subject, the Concordia University researchers chose to analyze 15 studies to reach their conclusion.

“Some results vary depending on the time of the exercise, others depend on the degree of physical condition of the participants or the type of exercises performed,” explained Ms. Mograss.

The aim of this study was therefore to evaluate the impact of high-intensity training on sleep.

“Researchers statistically analyzed and combined data from the 15 studies to explore variables such as timing of exercise,” reads a statement released Tuesday.
