“Hundreds of sea-swimming novices are taking to the ocean in February for the aptly named ‘Freezbrury’ challenge.

It involves getting into cold water every day of the month, wearing only your bathing suit.

Each day, swimmers stay in the water one minute longer than the last, eventually building up to a full 28 minutes.

The challenge was created to raise awareness around mental health and suicide prevention.

The Irish Sea is at its coldest during the month of February, with temperatures averaging around 6 degrees celsius.

Getting into cold water also has great physical benefits.

It’s been linked to improved circulation, skin and in some cases, even acts as a pain reliever.”
