Aggarwal was born on 11 January 1969 in New Delhi, and was raised in Chennai. She was a gold medalist in sociology at Delhi University. After a brief stint in modelling, and VJing, she made her Bollywood debut with the musical blockbuster Aashiqui, following which she was much in demand. In 1999, she had a near fatal accident in Mumbai and was treated at Breach Candy Hospital, to recuperate after a 29day coma.She lives in Bihar and is single. She practices yoga at the Bihar school of yoga in Munger, Bihar. She is also an amateur powerlifter and after her accident has competed in many powerlifting competitions. She quoted in one of her interviews "To feel strong, to walk amongst humans with a tremendous feeling of confidence and superiority is not at all wrong. The sense of superiority in bodily strength is borne out by the long history of mankind paying homage in folklore, song and poetry to strong women". Nowadays,She is reserved for teaching Mumbai’s slum kids AnuFun Yoga, a healing module she developed after years of experimenting with Vipassana, Craniosacral therapy and Tantra across ashrams in Uttarakhand and Kutch. She teaches it for free. Sanyas mandates that she live frugally, rid herself of the burden of possession. Sometimes, that means shorning her waistlength hair to earlength; at others, it is to sell off her seafacing Worli apartment, leaving with 11 cartons — 10 of them ready to be sent to Dharavi NGO Zaroorat. In 2015, Aggarwal wrote an autobiography titled "Anusual Memoir of a Girl who Came Back from the Dead" recounting her times in Bollywood and the accident that changed her life.
