When her Iranian jailors gave her a rare glimpse of joy, she had been separated from her family for months.
She was granted access to a TV with two channels in July of 2016 after months without books or newspapers.
She said that they didn't know what they had given her.
She was able to watch Andy Murray win his second Wimbledon title from her home in north London, but more than 3000 miles away from her prison cell.
Nine months after she was released, the 45 year old met Murray and shared the personal significance of that match, as part of her guest edit of Radio 4's Today programme.
She told Murray that she was in solitary confinement when he won the match. I can't tell you how happy I was to see you win.
She wanted to find tickets to the next year's final so she would email Murray.
She said that it didn't happen because she was in prison for so long.
After moving out of solitary confinement, Nazanin taught other inmates the story of Murray's victory.
She said it felt like an escape. I was close to my house all of a sudden.
Murray said it was the strangest story he had been told about someone watching him.
He said that listening to her experience of that day put issues in his own life into perspective.
"We all have our own problems, but after listening to you and speaking to you I will make sure I'm a lot more grateful for everything that I have," he said.
A British-Iranian woman was about to fly home from Iran with her two-year-old child when she was arrested.
She was accused of trying to overthrow the government in Tehran. She insisted that she took her daughter to visit her family.
She was freed in March after a long campaign by her husband.
If he was in her position, Murray would be very angry.
I would like to hear what you think about it all. He said that if he were in that situation, he would be angry.
At times I feel angry, but I decided to put the anger away and not carry it with me, because it will eat me up for the rest of my life.
When asked about life in prison, Nazanin said she would take refuge in the library and spend most of her time cooking and doing craftwork with other inmates.
She said that she missed her friends when she came out.
It's very strange to say that. I don't know if people can say that you miss prison, but I think that I miss the environment and my friends in prison.
