As a 4x World Champion freediver M1 2025 and 4x World Records holder M1, Helena Bourdillon performed under literal life-or-death pressure. This isn't metaphorical, because at -79 metres depth on a single breath, Mental Fitness isn't optional — it's what keeps her alive. 

But her expertise doesn't come from achievement alone. It also came from her recovery. 

From the age of 11, she battled severe depression and anxiety, resulting in self-harm, and suicidal ideation. Through her journey of recovery, she discovered that the tools for rebuilding mental health are almost identical to those for achieving sustainable high performance, because Mental Fitness isn't separate from excellence — it is the foundation of it. 

In her keynote, she demonstrates 5 practical, science-backed Mental Fitness tools that rebuild self-trust, eliminate imposter syndrome and decision paralysis, and turn reactive crisis management into clear, confident, and sustainable performance. Not through theory or motivation, but through methods she’s proven work under extreme pressure. 

As an Advanced Oxygen Advantage and Buteyko Method Breathwork Instructor, she combined elite athletic performance, clinical mental health recovery, and professional breathwork certification to deliver what high-stakes sectors actually need: performance architecture that works when pressure is constant and clarity determines outcomes.
