Diamond Vision Published July 13, 2009 By Master Sgt. John Deegan 755 AES First Sergeant KANDAHAR, Afghanistan -- Want to feel better, have more energy and perhaps even live longer? Look no further than old-fashioned exercise. Need to blow off some steam after a stressful day? A workout at the gym or a brisk 30-minute walk can help you calm down. Exercise stimulates various brain chemicals, which may leave you feeling happier and more relaxed than you were before you worked out. You'll also look better and feel better when you exercise regularly, which can boost your confidence and improve your self-esteem. Exercise even reduces feelings of depression and anxiety. Want to drop those excess pounds? Trade some couch time for walking or other physical activities. When you exercise, you burn calories. The more intensely you exercise, the more calories you burn -- and the easier it is to keep your weight under control. You don't even need to set aside major chunks of time for working out. Take the stairs instead of the elevator. Walk during your lunch break. Do jumping jacks during commercials. Better yet, turn off the TV and take a brisk walk. Dedicated workouts are great, but activity you accumulate throughout the day helps you burn calories, too. Struggling to fall asleep? Or stay asleep? It might help to boost your physical activity during the day. A good night's sleep can improve your concentration, productivity and mood. And, you guessed it, exercise is sometimes the key to better sleep. Regular exercise can help you fall asleep faster and deepen your sleep. The timing is up to you -- but if you're having trouble sleeping, you might want to try late afternoon workouts. The natural dip in body temperature five to six hours after you exercise might help you fall asleep. Exercise doesn't have to be drudgery. Join intramural sports. Check out a local climbing wall or hiking trail. Push your kids on the swings or climb with them on the jungle gym. Find an activity you enjoy, and go for it. If you get bored, try something new. If you're moving, it counts! Are you convinced? Good. Start reaping the benefits of physical activity today!
