Cold water habituation following lockdown

Following lockdown all swimmers will need to be careful. The water temperature is colder now than when you last went swimming and you will need to start the habituation process again. Start off slowly, reducing the time you normally spend in the water. Gradually increase your swimming time each day until you are fully habituated.

Please remember the risks associated with cold water swimming, even for regular winter swimmers:

  • Dangers include hypothermia, and cold shock or Sudden Immersion Syndrome.
  • Enter the water carefully, and avoid diving, especially if you are new to cold water swimming.
  • Know your limits and leave the water if you have any concerns or if advised by the Lifeguards.
  • After your swim, warm up slowly with plenty of layers. Sip hot drinks, and avoid hot showers and vigorous exercise - warming too quickly can be dangerous.
  • Speak to your GP about any medical conditions before you swim.
