Kiki Bosch is a Dutch ice freediver who uses the Wim Hof method of cold water tolerance to dive in extreme temperatures. Kiki specialises in ice dives without a wetsuit and (incredibly) has freedived in sub-zero temperatures – including in the Arctic – wearing only a swimsuit.

Here, Kiki explains how the cold water brought her peace after a traumatic event, and how it feels to freedive in extremely low temperatures without a wetsuit. She also shares a fascinating insight into managing her body and its cold water response.
