Actress Sandhya Mridul says essaying the hardships of a single mother in TV show "P.O.W. Bandi Yuddh Ke!" does take a toll. She says yoga helps her unwind from all the mental and emotional stress.Sandhya is portraying the role of Nazneen Khan, mother of two children who single-handedly brings them up while her husband Imaan Khan (played by Satyadeep Misra) is missing in action since the Kargil War. "I try to put myself into Nazneen's shoes and live her character. It's very difficult to understand the mental trauma that the wives of our war heroes go through. The only way I do it is by honestly approaching my emotions and tapping into the pain that would exist in a character like Nazneen," Sandhya said in a statement.She added: "I do a lot of breathing exercise and breathings on the sets that helps me. When I'm home after shooting for an intense sequence, it's hot water, the tub, Epsom salt, some nice music and yoga that helps me unwind from Nazneen's character." Filmmaker Nikkhil Advani's "P.O.W. Bandi Yuddh Ke!", which will be aired on Star Plus starting from November 7, is an Indian adaptation of Israeli TV drama "Hatufim". It reveals the story of two missing-in-action soldiers who return home after 17 years.
