Sweat Sessions Work Out the Brain, Too
Forget brainteasers. If you want to keep your mind sharp, break a sweat. In a study, 37 sedentary adults ages 57 to 75 were assigned to either stay inactive or take part in 12 weeks of supervised aerobic exercise training. Researchers tested participants’ memory and overall brain function, and monitored brain changes by measuring blood flow to the brain. In the exercise-training group, but not the inactive group, memory improved and blood flow increased to parts of the brain linked to better mental functioning later in life. Not only that, but exercisers experienced benefits as early as six weeks in.
