Many studies have shown that regular activity and exercise can improve overall health substantially. Exercise reduces the risk of heart disease by up to 35%, stroke by about 28%, certain cancers by 20% and more, and high blood pressure by an amazing 52%. Exercise can also help you to build healthy bones and muscles. Athletes must do physical training on a regular basis to increase their level of performance. Exercising includes walking, running, biking and plenty of other activities as well. My advice would be to pick something you enjoy doing and wouldnt mind pursuing on a regular basis. Then, you must stick to a schedule. You can even pick a few different activities to mix things up and keep it interesting. Also, always stretch before physical activity! This is very important as you do not want to pull muscles. Most importantly, to keep a healthy body you must stay ACTIVE!Understanding a radio programHere at this Chicago High School and others, there has been so much emphasis on the quality of school menus, but this new study says that none of that really matters when fast food is just a short walk away.How can a cafeteria ever hope to compete with this? A new Harvard study says more and more schools now have to. Eighty percent of schools in Chicago with a fast food restaurant less than half a mile away, raising concerns about how easy it is for kids to eat poorly, and whether fast food companies are moving into the neighborhood on purpose.“ they take into account the demographics of neighborhoods, the roadways in neighborhoods, and where the access is to the consumer base.”Doctor Bryn Austin is the studys lead author and says on a typical day, nearly a third of American kids eat fast food. When they do, they consume more fat and calories, fewer vegetables and fruits than on days when they dont.Overall, nearly nine million children in the US are overweight or obese, more than one in every seven kids, a number that has tripled since 1980. McDonalds criticized the Chicago study, saying most restaurants are in heavily trafficked areas. Schools said their spokesmen have nothing to do with it. But child health advocates like Doctor Matte Longjohn say the study shows how recent attempts to improve school menus, even remove soda vending machines, may not be enough to improve childrens eating habits.Listening and speakingPeople talk endlessly about the benefits of exercise. And when they arent talking about it, theyre reading about it in health magazines, watching programs about it on television, or liste
