by its physical aspect allows students' bodies to oxygenate and stay awake. Restriction of recess as disciplinary action In many schools around the country recess is taken away from students as disciplinary action. In 2013, researchers form the University of Chicago Illinois found that 68 percent of school districts had no policy or law prohibiting educators to take away physical activity from students. Because of this, many educators and administrators take away recess as a punishment. A Gallup poll conducted in 2009 revealed that 77 percent of principals say that they have taken away recess from students. Oftentimes students serve punishments such as completing late work or talking to the principal regarding behavioral issues during their recess times. However, by taking away recess, students are unable to release any excess energy that they may have. Releasing this excess energy can lead to better behavior and academic performance. Although taking away recess as disciplinary action seems to be the decision in many schools, researchers are coming up with alternatives for the elimination of recess. Some of these alternatives include positive reinforcement which rewards children for positive behavior rather than taking away things for negative behavior. In this situation, every child is guaranteed recess. International recess In the United Kingdom and Ireland, high school (11–16 or 18) students traditionally do not have 'free periods' but do have 'break' which normally occurs just after their second lesson of the day (normally referred to as second period). This generally lasts for around 20 minutes. During break, snacks are sometimes sold in the canteen (U.S. cafeteria) and students normally use this time to socialize or finish off any homework or schoolwork that needs to be completed. Once break is finished, students go to their next class. Lunchtime commences one or two lessons later and usually lasts around 45–60 minutes. This system is more or less the same in junior schools (7–11) in the UK and Ireland and in high schools (14–18) in the U.S., but infant schools (4 or 5–7) normally add another break time towards the end of the day. In Australia, New Zealand, and Canada "recess" or playlunch is generally a break between morning and mid-morning classes. It is followed after mid-morning classes by a more lengthy break, lunchtime. Thus, the structure of the school-day consists of three lesson blocks, broken up by two intervals: recess and lunch respectively. There must be at
