Scientists find that these challenges protect us from issues like obesity, heart disease, cancer, diabetes, depression, anxiety, and even a lack of meaning and purpose.

Sauna, cold plunge, and breathwork enhance mental health, immune health, endocrine function, metabolic health, and cellular health. Scientists and doctors have researched the benefits of regular hot and cold sessions for decades, publishing their findings in top peer-reviewed journals.
