Health benefits

Sauna culture is rapidly gaining popularity in the UK, with an increasing number of people discovering the numerous health benefits long-advocated by our European counterparts. Regular sauna use can improve cardiovascular strength, improve respiratory health, boost the immune system, and reduce stress levels.

Mental well-being is often noticeable after just one session, and sauna provides a tranquil space to unwind and focus on self-care. Incorporating regular sauna sessions can aid in post-workout recovery, especially after high-intensity exercises like running. Cold shock/contrast therapy offered by alternating between hot and cold temperatures can have numerous health benefits.

Sauna use is also associated with other wellness practices such as yoga and the Wim Hof Method.

Private hire guests: if you and your group wish, you are welcome to sauna in the traditional way. However, you will need to cover up outside as our sauna is on a public beach. This could be with a hammam towel that you don’t mind getting wet.

Although we do have a small changing tent on site with room for two people, please consider arriving already wearing your swimsuit (if required) and preparing to change on the beach. If you would like to make use of the changing tent, please arrive at least 10 minutes prior to your booking to avoid queueing.

We recommend cooling off outside between rounds by using our watering can showers, or, ideally, by jumping into the sea (if conditions allow).
