A report has found that more than half about after at behind for in of out up with high school boys and two-thirds about after at behind for in of out up with girls never shower about after at behind for in of out up with a physical education class. Researchers suggest that students don't want to sweat and take a shower, so they are less active about after at behind for in of out up with sports classes. The researchers questioned almost 4,000 children about after at behind for in of out up with schools in Essex, England. Lead researcher Dr Gavin Sandercock said he was surprised about after at behind for in of out up with how rarely students showered. He said: "We know that children aren't getting enough physical activity because we have seen their fitness declining; if the unwillingness to shower is a barrier to working about after at behind for in of out up with a sweat or playing sport, it's something we need to tackle to promote activity about after at behind for in of out up with schools." The BBC says the study did not look about after at behind for in of out up with the exact reasons why the students did not shower about after at behind for in of out up with PE. There are other studies that point about after at behind for in of out up with the fear about after at behind for in of out up with bullying and humiliation may be about after at behind for in of out up with the reluctance about after at behind for in of out up with some students to shower. Undressing about after at behind for in of out up with front of peers may be too much about after at behind for in of out up with some children. Pamela Naylor, spokeswoman about after at behind for in of out up with a health organisation in England, said many children had concerns about after at behind for in of out up with their body image and that schools needed to address this. She said: "Schools, workplaces and local authorities all have a role to play about after at behind for in of out up with shifting attitudes so that physical activity, and what comes about after at behind for in of out up with it, like sweating and the need for showering, is encouraged and accommodated."
