Physician and Functional Medicine Practitioner Rick Cohen talks to Thomas Seager, PhD about how VO2 max measurements aren't the end all be all for health, how ice baths increased his breath hold time, and how markers of resilience improve health and longevity.

In this episode of Uncommon Living, Thomas Seager, PhD examines three different case studies of individuals who have drastically increased their testosterone levels by adopting a regular practice of cold plunge therapy.

Pamela Butler, a 60-year-old postmenopausal woman; Jeff Daubney, who recounts the greatest testosterone boost he’s ever seen in a client; and Eloise Desoutter, a healthy 30-year-old woman, share with Professor Seager their experiences of ice baths boosting their testosterone.

After sustaining an injury to his pelvis and groin during a training exercise, Fire Captain Sean Smiley was diagnosed with hypogonadism. He tried injectable testosterone, but found that the side effects far outweighed the benefits. However, all was not lost. After accidentally discovering that exercise after cold exposure increases testosterone levels, Sean found that his testosterone levels went from the low 200s all the way up to the 700s, all because he was getting into his cold pool before going to Judo classes. In this episode, Sean and Thomas Seager, PhD discus the science of cold plunge therapy, as well as what it means to be healthy in the modern world.
