Open-air swimming is internationally famous on Hampstead Heath with the Ladies’ Pond, the Men’s Pond, the Mixed Pond and the Parliament Hill Lido. The Ladies’ and Men’s Ponds are unique in the United Kingdom in being the only life-guarded open-water swimming facilities open to the public every day of the year. The Lido is a 60 x 27 metre uncovered, unheated swimming pool at Parliament Hill.

Cold water swimming guidelines

Swimming/immersion in cold water at the Ponds/Lido 

An independent safety audit of the Heath swimming facilities by Amateur Swimming Association has identified medical issues surrounding physical acclimatisation (Habituation) and psychological acclimatisation associated with all year round recreational swimmers who enter water that is below 12°C degrees.

Three main problems associated with immersion in cold water have been identified:

  • numb freezing cold injury
  • hypothermia
  • sudden immersion syndrome (SIS)

Before this activity is commenced, it is recommended that a medical check up occurs with the examining doctor having been told the purpose of the examination. For physical Habituation and psychological acclimatisation to occur, swimmers should continue from summer through autumn into winter, preferably three or four times a week, although only brief immersion is necessary to achieve Habituation, say for the order of two or three minutes, on each occasion.
