For over four decades, Austinites have braved the brisk waters of Barton Springs Pool on New Year’s Day for the iconic Polar Bear Plunge. This cherished tradition, hosted in partnership with the Save Our Springs Alliance, not only brings the community together but also raises awareness and funds to preserve one of Austin’s most treasured landmarks. Beyond the fun and frosty challenge, this event offers participants a chance to rejuvenate, reset, and experience the health benefits of cold water immersion in Barton Springs’ consistent 68°F waters.
If you’ve ever wondered about the science behind cold plunging or are curious about how it can enhance your well-being, Generator Athlete Lab in Austin, TX, has the answers. Dr. Jessica Tranchina, CEO and physical therapist at Generator Athlete Lab Downtown, shares why this practice is more than just a thrill—it's a powerful tool for physical and mental health.
As featured in The Austin Chronicle, the Polar Bear Plunge offers profound insights into the benefits of cold therapy.
What Is Cold Plunging?
Cold plunging, or immersing oneself briefly in water between 50°F and 70°F, may sound daunting, but its effects on the body are anything but. According to Dr. Tranchina, cold therapy activates the sympathetic nervous system, which governs the body’s “fight or flight” response.
“You feel like you’re fighting the bear,” explains Dr. Tranchina. “It activates what we call the sympathetic nervous system, known as the fight or flight [response].”
This activation triggers a cascade of biological reactions, including the release of mood-boosting hormones such as dopamine, serotonin, endorphins, and norepinephrine.
The Science-Backed Benefits of Cold Plunging
The positive effects of cold plunging extend well beyond the initial shock of the cold. Regular exposure can deliver both short- and long-term health benefits:
1. Improved Focus and Mood
Cold plunging increases dopamine levels in the brain, promoting clarity, motivation, and a sense of well-being.
“The more you consistently do cold plunging, the higher your threshold and levels of dopamine in your body,” Dr. Tranchina explains. “Even when you’re not cold plunging or you didn’t cold plunge that day, you feel more focused.”
2. Cardiovascular Strength
When exposed to cold water, the body redirects blood flow to protect vital organs, and upon rewarming, the blood circulates back through the arteries and veins.
“It’s like flexing the muscles of your vascular system,” says Dr. Tranchina. This process improves circulation, boosts cardiovascular resilience, and promotes overall heart health.
3. Immune System Support
Cold therapy also stimulates the lymphatic system and enhances immune function by promoting the release of white blood cells.
“You release white blood cells in this proportion when you’re sick,” says Dr. Tranchina. “The only other time that [white blood cells] are released in this quantity is in a cold plunge – which is basically hacking your body.”
This immune boost helps the body fight off toxins and damaged tissues, making it a valuable recovery tool for athletes and wellness seekers alike.
Safety Considerations
While the benefits of cold plunging are significant, it’s essential to approach the practice safely. Cold therapy may not be suitable for individuals with certain medical conditions, including heart issues. If you’re new to cold plunging, start with shorter durations and gradually build your tolerance.
