Why I Love Cold Plunging (And Why You Should Try It Too)

Welcome back—I'm so happy you're here!

After a long day (or week), one of my favorite ways to reset my mood is a cold plunge. Now, before I dive into this, I must preface that the jury is still out on the extent to which science truly backs up these findings. But to be completely honest, the split between placebo and proven science doesn't matter much to me—as long as I walk away feeling better. Since this practice has had such a meaningful, positive impact on my life, I want to share what I've uncovered through research and personal experience.

Why I Keep Coming Back to the Cold

If you're thinking this sounds like the last thing you'd want to put yourself through, I get it. That's exactly how I felt initially. Why would I subject myself to cold and discomfort?

Two things keep me coming back:

The mood boost. This is truly the most important and impactful aspect in my experience. As much as I dread it beforehand, I always walk away feeling lighter and brighter, with a spring in my step. The cold water jolts me awake, leaving me energized and simply happier.

The sense of accomplishment. I'm naturally competitive, and setting these little challenges—seeing how cold I can go or how long I can last—is incredibly satisfying. No matter how big or small, having a reminder that we can do hard things and meet (or exceed) our expectations always feels good.

The Science Behind the Sensation

What reinforces this habit and keeps me coming back is that the benefits may be backed by science (though the extent is debatable). There are three main categories of potential benefits: physical fitness, mental health, and cosmetic.

Physical Benefits

Cold water exposure can positively affect your muscles, immune system, and circulation. The exposure is naturally anti-inflammatory, which can reduce joint inflammation and muscle soreness. The cold constricts blood vessels and slows cellular processes, giving your body a chance to recover after hard workouts and potentially reducing that dreaded next-day soreness.

Some studies also suggest cold water exposure may increase white blood cell count, meaning people who regularly cold plunge might get sick less often.

Mental Health Benefits

This is my favorite part, and something I've definitely noticed personally. Mammals have a natural diving response—our bodies conserve oxygen for the heart and brain when they sense we're underwater. Cold water shock, especially when you quickly submerge your face (your whole head isn't necessary), triggers this response and causes your heart rate to slow. It's like a natural chill pill.

Studies also suggest that cold shock releases norepinephrine and dopamine—the happy hormones. At minimum, the cold shock will give you a serious energy boost.

Cosmetic Benefits

The anti-inflammatory effects can reduce puffiness, while improved circulation helps even out skin tone and reduce redness over time (though you'll definitely turn red immediately after getting out while your body warms up).

Cold water can also give you healthier, shinier hair by helping seal the hair cuticle and reducing your skin's oil production, potentially leading to less frizzy, more happier hair.

Ready to Take the Plunge?

Whichever aspect of cold plunging interests you most, I truly hope you'll give it a try. If it's not for you, that's perfectly fine. But you might discover some of the benefits I've described here—or find your own reasons to keep coming back.

You don't need a fancy contrast therapy studio to get started. I'm lucky to have a cold plunge tub at my local gym, but a natural body of water works just as well (especially during off-season months—the beach in May would be more than adequate). Even turning your shower to cold for a few minutes delivers the same benefits.

Why not give it a shot? Your future self might thank you.
