The monsoon seems to have affected singer Sonu Nigam the most as he is falling ill quite frequently. “This season hit me the worst in terms of health. Every second day some infection. In bad shape since last night. Work, work & work (sic),” Nigam tweeted. “I need to work on my immunity. Getting back to yoga, much needed because clearly enough, staying happy always, doesn’t seem sufficient (sic),” he posted.
