depression among children, as well as attention deficit hyperactivity disorder. Childhood obesity and type 2 diabetes Childhood obesity and type 2 diabetes are also a major concern as United States youth do not get the physical outlet needed not only for their cognitive development but for their physical health. Statistics show that children are getting 50% less physical exploration and activity than decades before. Research has shown that spending 60 minutes a day doing physical activity can prevent childhood obesity. The U.S. Health and Human Services department also has a guideline for 60 minutes a day of physical activity. But, research has shown that only very few children actually meet this national guideline. Failure to meet this guideline and exercise daily is leading to harmful health issues for children. Recess can be an outlet for students to get some of this physical activity and aid in preventing childhood obesity and diabetes. Timing of recess Another important aspect of recess to consider is what time of day it should be implemented. Traditionally schools have recess after lunch. But, in 2002, the Recess before Lunch (RBL) movement was founded. A health team in Montana created a study on four schools that made this schedule adjustment. After this study, many schools have started adapting the recess before lunch schedule. Research suggests that having recess before lunch can improve the nutrition and behavior of elementary students. Effects on classroom behavior According to the American Heart Association, the CDC reported that there is a link between physical activity and academic performance in 2010. Some benefits to recess include students being more attentive, better academic performance and better behavior. Many different studies show recess as being beneficial to students in the classroom. One of the goals of recess is to help students release excess energy and be refreshed focused upon return to the classroom. According to a 2009 study, children who received daily recess were reported to behave better within the classroom. After a long time in the classroom, students may become restless and disengaged. Studies show that after recess students become more attentive and engaged in classroom discussions. This is because recess gave students a necessary break from the rigorous classroom and learning setting. A 2017 study of fifth graders suggested that 25 minutes of recess could increase students' time on task. Also, recess can reduce the risk of students falling asleep during learning time
