Psychology Today came out with an article reporting a new study that shows how low intensity exercise stimulates our brain networks that relate to cognitive control and our attention. Researchers also found that high intensity exercise activates brain networks related with emotional processing. Both intensities of exercise are associated with an increase in positive mood. Including both high and low intensity in a workout can affect how you think and feel. In the past scientists have gone on daily walks to stimulate cerebral brain functions. No matter what the intensity is, physical exercise can help improve your memory and mood!
