The monsoon seems to have affected 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, " Sonu wrote on his Twitter page.

The singer now plans to get back to yoga and improve his immunity.

"I need to work on my immunity. Getting back to yoga, much needed because clearly enough, staying happy always, doesn't seem sufficient, " Sonu posted.
