SEE ALSO: Secret Swimming, Let's Go Skinny Dipping
If you're already feeling the autumn chill, spare a thought for the 180 or so brave souls who bared all for a mass skinny dip in the North Sea.
The second annual North East skinny dip took place at Northumberland's chilly Druridge Bay, at dawn this Sunday.
"This event isn't about looking good. It's about taking a risk, celebrating our unique bodies, being close to nature, [and] raising money for charity," the official site states.

Registration is £10 per person and individuals were encouraged to individually fundraise too. Last year the naked stunt earned £4,500, the Journal revealed.
Funds raised will be shared between The Mental Health Charity, MIND, and conservation work of the National Trust on the Northumberland coast.
The goose-fleshed event was organised by Jacqueline Higginson, a regular sea swimmer who was inspired after taking part in a similar event in Wales in 2011.
Following the success of the first skinny dip last year, she told Shields Gazette: "I had loads of people email me saying what a life-affirming experience it had been and that they definitely want to do it again."
Simon Lee, from the National Trust, which owns Druridge Bay, told the BBC: "They were from all walks of life, different ages, there was a great team spirit to it, a lot of laughter."
