It's the season to be chilly with festive swims taking place across the region to help cure those Christmas Day hangovers.
From Cromer to Southwold, there are events taking place along the east coast and many raise money for charity too.
Here is a round-up of the seven best Christmas Day and Boxing Day swims taking place in Norfolk and Suffolk.
Cromer
Boxing Day
Organised by the North Norfolk Beach Runners, the Boxing Day swim in Cromer will be raising money for MIND (Norwich and Central Norfolk) in memory of one of their young members Nyall Brown who passed away earlier this year.
The event is back to its original time of 11am this year with a fun run also taking place at 10am, starting from the Cromer Pier forecourt.
The tide is set to be quite high so they will be using the two beaches as they did last year.
If you are planning to swim, make sure to wrap up warm immediately after and St John Ambulance, Cromer Coastguards and RNLI will be in attendance for your safety.
Hunstanton
Christmas Day
The annual Christmas Day swim attracts thousands of spectators every year far and wide and has been running for over 50 years.
The swimmers wear fancy dress and brave the icy waters to raise money for charities in the local area.
Registration begins at the Oasis Leisure Centre in Seagate Road at 10.30am and entrants will parade into the sea at 11am.
There will also be refreshments available from the Waterside Bar and Restaurant on Hunstanton Central Prom.

Mundesley
Boxing Day
Refreshments are served from 10.30am and the dip in the sea takes place at 11am.

Overstrand
Boxing Day
The event will begin at 10.30am at the bottom of the ramp leading onto the beach at the west end of the village.
