Safety Guidelines

SaunaSwim is about enjoying nature safely. Please read these guidelines before your visit.

Water safety

  • Cold water shock can affect even strong swimmers — enter slowly and never dive in headfirst.
  • Never swim alone. Always bring at least one other person who can call for help.
  • Check conditions before you go. Look up water quality reports and avoid swimming after heavy rainfall.
  • Know your exit point before you get in, and stay within a sensible distance of shore.

Sauna heat guidance

  • Stay hydrated — drink water before, during, and after your sauna session.
  • Limit sessions to 10–20 minutes at a time, especially if you're new to saunas.
  • Cool down gradually. A cold shower or slow walk outside is safer than jumping straight into cold water.
  • Avoid alcohol before or during sauna use. It raises the risk of overheating and dehydration.
  • If you feel dizzy, nauseous, or faint — leave immediately and sit somewhere cool.

What to bring

  • A towel — essential for both sauna and swim.
  • A reusable water bottle. Hydration is key for both activities.
  • A swim buddy. Solo wild swimming is not recommended.
  • Appropriate footwear for uneven or slippery terrain around natural swim spots.
  • Dry clothes and a warm layer for after your swim.

In an emergency

  • Call 999 immediately. In coastal or river emergencies, ask for the Coastguard.
  • Throw — don't go. Use a lifebuoy, rope, or floating object rather than entering the water yourself.
  • If someone is in cold water shock, help them float calmly and call for help. Reassure them while waiting.
  • For heat-related illness in a sauna, move the person to a cool area, loosen clothing, and apply cool water to skin. Call 999 if they lose consciousness.

When not to swim

  • After heavy rainfall — rivers and lakes can contain elevated bacteria levels.
  • In amber or red weather warnings — strong currents, high winds, and lightning all increase risk.
  • If you have a heart condition, epilepsy, or are pregnant — speak to your GP before cold water swimming.
  • If the water temperature is below 10 °C and you're not acclimatised — build up gradually over time.
