July-August 2015 – Choose to Say YES to Physical Activity
.
FACT: Childhood obesity has more than doubled in children and quadrupled in adolescents in the past 30 years, the result of a diet high in processed foods as well as reduced physical activity.1
HOPE: A study of 11,743 public school students showed that physically fit students performed better on standardized reading and math tests than those who were not aerobically fit. Weight and BMI were also measured but did not influence the results.2 Parents, remember that encouraging kids be active is just as important as the time they spend on homework!

FACT: In the U.S., nearly 20 percent of adults report moderate to excessive sleepiness during the day, and 11 percent report severe sleepiness.3 
HOPE: The more active you are, the better you sleep. One study of more than 2,600 people, ages 18-85, showed those who accomplished 150 minutes of moderate to vigorous exercise per week reported a 65 improvement in their quality of sleep—and felt less sleepy during the day!4
 
FACT: In 2012, 14.1 million new cancer cases were diagnosed. An estimated nearly 1.7 million Americans will be diagnosed with cancer in 2015.5, 6 Many of these cancer patients face a treatment regimen of surgery, chemotherapy, radiation therapy or some combination.
HOPE: A growing number of studies are showing the benefits of exercise during cancer treatment. Physical activity can have a positive effect on undesirable side effects of treatment such as pain and fatigue as well as providing the benefits of bodyweight, fitness, strength and flexibility. One study showed that women with breast cancer who exercised while undergoing chemotherapy were able to lower their drug dose and had fewer delays during therapy.7 
 
FACT: Those who live without exercise experience greater risk for a number of health problems including high blood pressure, coronary heart disease, anxiety and depression, cancer and obesity.8 
HOPE: In a recent study of a group numbering more than 661,000 adults—most in middle age—those who completed 150 minutes per week of moderate exercise were 31 percent less likely to die over the study’s 14-year period, and those who exercise 450 minutes per week or just over an hour per day saw 39 percent less risk of death. Surprisingly, even those who exercised less than the recommended 150 minutes per week experienced a 20 percent reduction in risk of death. If you only have time for a 10 minute walk, do it! You’re still taking years off your life.
