Polar Plunge: A Chilly New Year’s Tradition with Potential Health Perks
On New Year’s Day, people across the globe will ditch their cosy cars and heavy winter layers to participate in a bold tradition: the polar plunge. Clad in just bathing suits and towels, they’ll dive into icy waters to welcome the new year.
For some, it’s a symbolic way to wash away the past and start fresh. For others, it’s an opportunity to explore the potential health benefits of cold-water immersion, which include everything from easing depression to improving blood sugar levels.
The Science Behind Cold-Water Immersion
Relief for the Body and Mind
Cold-water immersion has long been studied in athletes for its ability to reduce physical pain and inflammation. According to Dr McMullen, the practice might also benefit mental health by reducing stress and anxiety.
Boosting Immunity
There’s evidence that repeated exposure to cold water may enhance immune system health.
“Cold water immersion has been shown to increase the concentration of certain immune cells and proteins,” McMullen explains. However, these benefits are more likely for those who plunge regularly rather than just once a year.
The Risks of Cold Plunges
While the benefits are intriguing, cold plunges aren’t for everyone. People with certain conditions should consult their doctor before taking the icy leap, such as
- Heart problems,
- High blood pressure
- Hypothyroidism
- Raynaud’s phenomenon
Even for healthy individuals, the risks are real. Cold water immersion triggers a “cold shock” response, which can spike
- Heart rate
- Blood pressure
- Stress hormones
Sudden gasping, erratic breathing, and shivering are common reactions as the body works to keep its core warm.
Safety First
Dr. McMullen advises staying in the water for only a few minutes, especially if you’re a first-timer.
“As benign as it may seem, cold water immersion can be dangerous,” he warns, noting that drowning is more likely in colder water.
The Rising Popularity of Cold Plunges
In recent years, cold plunging has gained traction, thanks to social media and influencers touting its benefits. Thousands of groups now practice it regularly, with many sharing their experiences online.
“It’s surprising to see how popular this has become,” McMullen says. But he emphasizes that while the trend is growing, more research is needed to fully understand its effects.
Should You Try a Polar Plunge?
If you’re intrigued by the idea of a polar plunge, go ahead and give it a try—but take precautions. Start slow, stay safe, and consult a healthcare professional if you have any health concerns. Whether you’re seeking a symbolic fresh start or exploring potential health benefits, diving into icy waters is sure to leave you feeling refreshed—and maybe even a little exhilarate.
