Exercise Your Body and Brain
Sure, you get toned abs and weight loss. But don't Forget happiness and smarts.
Maybe you exercise to tone your thighs, build your biceps, or flatten your belly. Or maybe you work out to ward off the big killers like heart disease, diabetes, and cancer. But how about sweating to improve your mind? "Exercise is the single best thing you can do for your brain in terms of mood, memory, and learning," says
1. REVERSE THE DETRIMENTAL EFFECTS OF STRESS
Jumping on the treadmill or cross trainer for 30 minutes can be an instant way to blow off tension by boosting levels of "soothing" brain chemicals like serotonin, dopamine, and norepinephrine. What's fascinating, though, is that exercise may actually work on a cellular level to reverse stress's toll on our aging process, according to a May study from the
2. LIFT DEPRESSION
Research suggests that burning off 350 calories three times a week through sustained, sweat-inducing activity can reduce symptoms of depression about as effectively as antidepressants. That may be because exercise has been found to stimulate the growth of neurons in certain brain regions damaged during depression. What's more, animal studies have found that exercise boosts the production of brain molecules that improve connections between nerve cells, thereby acting as a natural antidepressant.
3. ENHANCE LEARNING
Exercise increases the level of brain chemicals called growth factors that help make new brain cells and establish connections between cells to enhance learning. Interestingly, complicated activities, like playing tennis or taking a dance class, provide the biggest boost. "You're challenging your brain even more when you have to think about coordination," explains Ratey. "Like muscles, you have to stress your brain cells to get them to grow." Complex activities also upgrade the capacity to learn by enhancing attention and concentration skills, according to German researchers, who found that high school students scored better on high-attention tasks after doing 10 minutes of a sophisticated fitness routine compared to 10 minutes of regular activity. (Those who hadn't exercised at all scored the worst.)
4. BUILD SELF-ESTEEM AND IMPROVE BODY IMAGE
You don't need to radically change your body shape to get a confidence surge from exercise. Studies suggest that simply seeing fitness success, like running a faster mile or lifting more weight than before, can improve your self-esteem and body image.
5. LEAVE A FEELING OF EUPHORIA
Yes, that "runner's high" really does exist if you're willing to shift into high-intensity mode. Ratey recommends sprint bursts through interval training. Run, bike, or swim as fast as you can for 30 to 40 seconds and then reduce your speed to a gentle pace for five minutes before sprinting again. Repeat four times for a total of five sprints. "You'll feel really sparkly for the rest of the day."
