Shooting in the scorching heat in Dholpur, Rajasthan, has taken a toll on Bollywood actor Irrfan Khan’s health.

According to a source from the film’s unit, Irrfan felt very uneasy due to dehydration and had a blackout while shooting  a scene for his forthcoming film Paan Singh Tomar.

"It was blazing hot. Irrfan had been shooting continuously under the hot sun. It was just too much of heat that caused this dehydration," the source said.
