A retired woman who has looked after her disabled daughter since she was born has described the pressures of being an unpaid carer in her 70s.
"I spend ages making plans and thinking: 'Well, I'm not going to be here to make sure it's all carried out when the inevitable happens'."
Mrs Naylor's daughter Gabrielle, who has Down's Syndrome, a heart defect and epilepsy, requires regular care that has been given to her by her parents ever since she was born.
"A few weeks ago we were on holiday, all three of us, but Gabrielle had an epileptic fit and then a stomach bug. It puts a dampener on things," she said.
An ageing population has seen growing social care needs and more reliance on unpaid carers, said the report from the University of Sheffield, in collaboration with charity Carers UK.
"I want recognition for all carers from society and government that we're out there doing a damned good job that would be very expensive if we didn't do it," she added.
Carers UK said it was using the research to call for a step change in the way carers were identified across society to ensure they got the practical or financial support they needed.
"Most carers would call themselves a loving partner, parent or child, and do not immediately identify their caring role - meaning many miss out on practical support as a result," she said.
She has already started looking at what they might do when they can no longer care for her, but has her reservations.
"You have to throw money at it. What if you haven't got the money to, though? What if you can't quite trust the people? That's a worry for me. Will they do it as well as I do?"
