Forcing your brain to process new information or do familiar things in unfamiliar ways can help stimulate brain function and improve your memory. According to Manning Rubin, coauthor of Keep Your Brain Alive, there are a number of simple mental exercises that can be done daily to boost brain health. Rubin told realsimple.com that improving memory and mental function can be accomplished by regularly exercising each of your five senses. For example, Rubin recommends changing the radio station on your alarm clock and getting dressed in the dark in order to stimulate your brain first thing in the morning. Picking your clothes out in advance and then dressing blindly forces your brain to work harder to compensate for the loss of one of your senses. He also suggests brushing your teeth with your non-dominant hand in order to challenge your brain.
