Increasing the Level of Physical Activity Can Boost Mood: Study
Increasing the level of physical activity can effectively boost one's mood, a study has found.
The researchers, published in journal JAMA Psychiatry, found that increases in physical activity tended to be followed by increases in mood and perceived energy level.
This beneficial effect was even more pronounced for a subset of the study subjects who had bipolar disorder, according to the researchers from Johns Hopkins Bloomberg School of Public Health in the US.
For the study, activity trackers and electronic diaries were used for two weeks in a community sample of 242 (150 women and 92 men) adults, ages 15 to 84, with an average age of 48 years.
The sample included 54 people with bipolar disorder.
Mobile assessments in the study included wrist-worn devices that automatically recorded levels of physical movement in real time and electronic diaries that assessed mood and perceived energy levels four times per day for two weeks.
These real-time mood and energy levels were rated by study participants on a seven-point analogue scale from “very happy” to “very sad” for mood and from “very tired” to “very energetic” for energy.
The findings showed that on average a higher activity level at one time-point was associated with improved mood and increased perceived energy at the next time-point during the day.
Likewise, increased energy at one time-point was associated with increased activity at the next time-point.
These associations controlled for the current levels of mood, energy and activity, respectively.
Activity was inversely associated with sleep duration - more activity tended to be followed by less sleep that night, and more sleep tended to be followed by less activity the next day.
Many of the current interventions for mood, sleep, and physical activity focus on only one of these systems rather than considering the collective impact across multiple systems.
“This study exemplifies the potential for combining the use of physical-activity trackers and electronic diaries to better understand the complex dynamic interrelationships among multiple systems in a real-time and real-life context,” said Zipunnikov.
