Kaniha made her acting debut in the Mani Ratnam produced 'Five Star' directed by Susi Ganesan which also marked the debut of Prasanna. Her most memorable film in Tamil is 'Varalaru' in which she portrayed a powerful character opposite Thala Ajith. Kaniha married Shyam Radhakrishnan in 2008 and son Sai Rishi was born in 2010 and the family is now settled in Kerala.

Kaniha for the first time has opened up about her difficult pregnancy and ailments her son had and she has done so to give confidence to many women out there. The post reads "Yes I had a big baby..I had an oversized,overflowing pregnant belly which I flaunted with pride. I didn't have the luxury of recovering post-delivery like many moms coz my child had to undergo an open-heart surgery soon after birth. Miracles do happen and my little one is a survivor and He chose life."

Kaniha has added "This post is not about that though..It's about how I managed to get back to my normalcy..I followed 1 simple rule. Your life, Your body ,Your right.
Till date I never let people's comments about my looks or my parenting ways bother me.I silently keep working on what I wanna achieve. Even today many of you may think/comment why do I pursue fitness?? Many of you think I do it for the sake of my career etc ..But the answer is NO.I do it for myself.It's an investment I am making for my healthier future.. So guys try to eat healthy, stay fit!! A healthy future lies in your hands today. All it takes is less than an hour everyday. You are definitely worthy so gift yourself good health. If I can do it,why can't you?"
