Recess is important because it helps students to release all of their pent-up energy and also to interact with their peers.
Reasons Why Recess Is Important for Students
Furthermore, because students are running around and receiving exercise, it helps them to develop and strengthen their brains.
Generally, the outdoor recess is the best because students get fresh air and Vitamin D, and they also spend time playing sports and games that they do not get to do in the classroom.

However, if the teacher has the impression that the playground is unsafe, then it would be better for the students to do indoor recess such as an arts and crafts project.
Overall, the benefits of outdoor recess exceed the negatives.
