Frequently Asked Questions
What safety precautions do I need to take?
General guidance
- If you have underlying health conditions (i.e. heart disease, asthma, lung conditions) or any other medical conditions that might be affected by exposure to cold water, or if you are pregnant, then please seek appropriate medical advice before proceeding.
- Read the official tips from The Outdoor Swimming Society
- Do not take part in the challenge under the influence of drugs or alcohol.

- This challenge is entirely at your own risk, so please assess your ability and safety before you participate. Teenage Cancer Trust shall not be liable for any injury, damage or loss to you or your property that might occur as a result of your participation.
- We strongly advise you let friends / family know about your participation in this challenge.

- For further reading and guidance please read the RNLI’s guidance on Cold Water Shock and Outdoor Swimmer’s guide to temperature.
Outdoor swimming
- Please note that Teenage Cancer Trust does not recommend outdoor swimming unless under supervision by trained staff eg. Lido
- Never take part in an outdoor swim alone and always let people know where and when you will be completing your dip. Take your mobile phone.
- Be safe and check local advice when choosing where to swim. Check local conditions, tides and RNLI reports. You are responsible for choosing a safe location and accessing your own ability. Choosing somewhere you are familiar with and can exit the water quickly is recommended. If you choose to swim in open water against our advice, ensure you are with someone qualified to ensure your safety and remember, if open water swimming other vehicles and boats may be using the water too. Wear bright colours so you are easy to see.
- Plan your dip in daylight hours and avoid swimming in the dark.
- Wear something you feel comfortable in that does not affect your ability to swim. Swim caps can help you retain your body heat. Wearing a wetsuit, swim gloves or swim booties can also help retain body heat too. Please make sure you do not wear anything that will become too heavy to swim in when it gets wet.
- When entering the water, allow yourself time to acclimatise to the cold by entering slowly. Do not jump in. Only go into water as far as you can stand. Don’t put yourself in unnecessary danger by going into deep water.
- Swim gently at first, allowing time to overcome the shock and shallow breathing which is a normal reaction to the cold water.
- If you feel very cold, disorientated or dizzy seek help immediately.
- After your swim, warm up gradually. Pat yourself dry and put on warm, dry layers – you could even make a warm drink. Avoid standing around and move to a warm location. Do not drive until you feel well.
