Stig Åvall Severinsen

Stig Åvall Severinsen is a four-time World Champion freediver and holder of two Guinness World Records. Freediving consists of diving deep or long while holding your breath.

He holds a Master’s degree in biology (2001) and a PhD in medicine (2007) from the University of Aarhus, Denmark. During the last decade he has practiced and investigated the beneficial effects of breathing and breath holding on body and mind.

His lifetime passion for water and breath holding lead him to write the book "Breatheology – the art of conscious breathing" which appeared in Denmark in 2009 with the title "Træk Vejret – mere energi, mindre stress". It quickly became a bestseller and was subsequently translated and published in English in 2010 by Idelson-Gnocchi.

Through his company BlueConsult, blueconsult.biz, and his international web community breatheology, he offers courses and lectures on efficient breathing and mental training.
