Saina snapped a 15-month title drought by claiming the India Grand Prix, beating rising star P V Sindhu in the final.
Reflecting on 2013, which saw her battle poor form and injuries, Saina said it was a case of everything going wrong at the same time.
"I was a little disappointed. Obviously, everyone gets disappointed when you play at such high level and suddenly you see yourself not doing so well. I think there were a lot of factors. There was a toe fracture which I never expected would happen at such a time," Saina told PTI in an interview.
"So, Gopi sir (national coach P Gopichand) and I decided that I better skip the Korea Open and take a break for four weeks and come back strong for Malaysia and India Open. I think the time of four weeks really helped us to prepare for these two tournaments," she added.
Saina said her results will depend a lot on her fitness in the months to come.
