The Science Behind the Benefits: Cold Plunging

The Science Behind the Benefits: Cold Plunging

If you're reading this, you probably already know the invigorating feeling of taking a plunge into icy waters. Not only is taking the plunge an intuitively refreshing and positive experience, but we’ve got science to back that, too. Beyond the initial shock, there's a world of well-studied benefits waiting to be explored.

In this blog post, we'll dive deep into the research-backed advantages of cold water immersion that make Fjord a game-changer in the world of cold therapy.


Antidepressant Effect of Cold Water Immersion

Picture this: you emerge from a super chilly plunge with a refreshed mind and lifted spirits. This isn't just a placebo effect – scientific studies, including sentiments backed by neuroscientist Andrew Huberman, suggest that cold exposure can stimulate the release of mood-boosting neurotransmitters like dopamine and serotonin. A natural, accessible way to chase away the blues? We’re in. In a study conducted by Rymaszewska et al. (2018), findings revealed parallel outcomes as 21 patients witnessed considerable alleviation from depression within a mere two-week period of undergoing whole body cold therapy. 

Metabolic Health: Brown Fat Activation

Unlock the secret weapon in your body – brown fat! According to work at Cleveland Clinic, brown fat activates at colder temperatures, right before you start shivering. Susanna Soberg's work highlights this exact occurrence, which plays a crucial role in burning calories and improving metabolic health. Fjord Cold Plunges provide a convenient means to kickstart your metabolism, supporting your fitness and wellness goals.

Energy & Vitality

Feel the surge of energy and vitality that comes with each Fjord plunge. Cold water immersion has been linked to increased alertness and energy levels, making it an ideal way to kickstart your day or overcome that mid-afternoon slump.

Improved Sleep

Sleep: the elusive desire for many. However, we're excited to reveal that achieving a restful slumber is indeed possible following a cold plunge session. Research, heavily influenced by Dr. Rhonda Patrick, suggests that cold therapy can improve sleep quality by regulating the circadian rhythm and encouraging the release of sleep-inducing hormones. While you may initially feel more alert and invigorated after the plunge, it actually helps synchronize your natural sleep cycles, enabling your internal clock to switch off at the appropriate time for a deeper, more rejuvenating rest.

Mindset: Mental Toughness & Resilience

Wim Hof, also known as "The Iceman," has popularized the concept of cold exposure for mental toughness. Cold plunges push your boundaries, teaching your mind to adapt and persevere in challenging situations. Strengthen your mental resilience with Fjord's accessible cold therapy.

Do you know what healed me? The cold water. It brought me back into reality. Instead of being guided by my broken emotions toward stress and sorrow, the cold water led me to stillness. 
- Wim Hof in 'Why the Cold is a Noble Force.'

Fat Loss

Turn up the heat on your fat loss journey! Studies have shown that cold exposure can stimulate the conversion of white fat (the kind we want to lose) into metabolically active brown fat. As you know from a few points, earlier, brown fat is good fat! Incorporate Fjord Cold Plunges into your routine as a refreshing strategy to support your weight management goals. 



Performance and Recovery

Improve circulation, reduce inflammation, and enhance recovery post-exercise — it’s truly a healthy hack for all. Even mainstream publications like Sports Illustrated boast the benefits. From Lady Gaga and Guy Fieri to LeBron James and Klay Thompson, cold-water immersion has truly become a practice of elite celebrities and performers to the best athletes out there. They swear by the plunge to perform at the level needed to stay in the game. And while we might not all be pro athletes or touring the world with hours on the stage, we likely all want to show up in our best form for life.
