The coroner said Ms Lord was on hormone replacement therapy (HRT) for the menopause and was taking medication for epilepsy.
Ms Lake said Ms Lord’s mental health was “noted as stable” in January 2023 but “there was evidence in the more recent past that she was acting out of character”.
A statement from her husband Clive Lord, read out in court, said: “Gaynor had recently watched a TV show about swimming in ice cold water.
“She’s never done it herself but I don’t know if in her confused state she may have been thinking about this.”
He said there was “no reason” for her to be in Wensum Park and it was not a park they had ever visited together.
Mr Lord said he had seen his wife before she went to work and they had discussed planning a holiday to Japan.
