Every day in October Jess will be cold water swimming. We meet along Hunstanton seafront, where she's chosen to take her morning dip. She explains why she's taking on the challenge.
"We have the most chalk streams in the world, and we need to protect them. Also, Hunstanton is a tourist resort, we want beautiful beaches and for people to feel confident about swimming in the sea without catching any nasty bugs."
As we stand and chat in our warm coats, I ask how she feels about getting into the less than inviting looking cold water.
"I think I'm part seal," she tells me, "Once I'm in, I'm fine - there's an initial shock and I do some breathing exercises to relax, so it takes me a few moments to acclimatise."
"There are days when I think why am I doing this, I'm tired, just done a 10 hour shift, but once I'm in I just come out buzzing and it's actually very life affirming.
"It gets you closer to nature. Swimming is amazing, but swimming in open water, is on a next level. I love it, it makes your skin tingle, it makes you feel very alive.
"And if I do it in the morning, it does wake me up for the rest of the day!"
In her swimsuit, hat and goggles - Jess walks in. Despite all the enthusiasm, I choose to offer encouragement from the shoreline.
Dip a Day is an annual fundraising and awareness campaign run by Surfers against Sewage. The charity says, "Participants commit to taking a cold water dip every day for all 31 days of October to raise money and protest against raw sewage dumping in British rivers, lakes, and seas.
"It's to raise funds to support the charity's clean-water campaigns, data tracking, and putting legal pressure on water companies and lawmakers."
I watch as Jess dives beneath the waves, swims for a bit, and gives me a wave. About ten minutes later, she walks out with the biggest smile on her face.
"That was amazing, it's lovely out there. It was fantastic, I'm just buzzing now." She does indeed look invigorated. "That was really fab, I'm a different person when I come out!" She walks off laughing to grab her towel and warm up.
I leave slightly (ever so slightly!) tempted to take a dip. Well done Jess for taking part in the challenge!
