What is Biopyrrin
Studies have shown that the production of active oxygen in the body is involved in the development of mental disorders triggered by psychological stress. When the amount of active oxygen increases in the body, a substance called “biopyrrin” increases accordingly in the urine. Biopyrrin has been reported to increase significantly under extreme psychological stress and/or with mental disorders.1-6 In May 2021, researchers (Wake, Miyaoka, Oh-Nishi et al.) from Shimane University School of Medicine discovered that the level of urinary biopyrrin starts to increase in patients with at-risk mental state (ARMS), a condition that existed prior to the onset of mental disorder.
The biopyrrin test is drawing attention as the world's first test method that can quantify the psychological stress that leads to mental disorders.7
Importance of stress care
Stress causes not only mental disorder but also various symptoms such as hypertension. Stress could be attenuated by reviewing daily life (preventing overwork, getting enough sleep and so on). However, it is difficult to be aware of it by yourself whether or not you are under stress and therefore, it is not easy to improve your life by behavioral changing. Urinary biopyrrin test is easy and suitable for frequent test and measurement, because a urine sample is used which can be easily collected anywhere.
