Studies indicate that physical activity may actually help!
Research indicates that physical activity actually helps with the formation of new neurological pathways. Studies also indicate that physical exercise, especially aerobics, helps "wake up" the brain by raising dopamine levels and flooding the brain with oxygen.

Take a walk, do some jumping jacks, run in place; studies indicate this will help!
