BREAKING! Hormones: Researchers Discover Phoenixin - New Human Hormone That Regulates Thirst Levels
: Medical researchers from Department of Pharmacology and Physiology, Center for Neuroscience Research, Saint Louis University School of Medicine, Missouri have discovered a new human hormone called phoenixin which could play a major role in adjusting a person's level of thirst according to the body's needs.
The breakthrough discovery of the hormone, which is made in the human body, bolsters scientific data showing that the amount of daily hydration is just as critical as how much food we eat.
The new hormone Phoenixin appears to control changes in thirst and other hormones that regulate body fluid balance that occur with aging, according to a recently published paper in the American Journal of Physiology
-Regulatory, Integrative and Comparative Physiology
. The study was initially conducted in animal models. https://journals.physiology.org/doi/full/10.1152/ajpregu.00023.2020
The study, which was conducted in rats, was chosen as an APSselect article for June.
The medical researchers focused on the physiologic control of thirst in females, which was more pronounced during the onset of puberty, menses and following menopause. They also studied how the mechanisms controlling thirst varied as both males and females aged, and how changes in gonadal hormones affected the ability to stay appropriately hydrated.
The research also shows that Phoenixin appears to control changes in thirst even during the ovarian cycle and pregnancy.
Interestingly, the pharmaceutical drug losartan which is used to treat high-blood pressure apparently disrupts the hormone’s functions, possibly implying negative health effects of the drug as Phoenixin is important for fluid and electrolyte homeostasis in the human body.
