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