Alright, so I’ve been kicking this idea around for a bit. You hear folks talking, right? Saying how sitting in a sauna, getting a good sweat on, is kinda like exercise. And I got to wondering, specifically about this claim: 30 minutes in the heat, what’s that really equal to in terms of actual, you know, moving your body type exercise? So, I figured, why not give it a go myself, see what the real deal is.

My Little Experiment Setup

So, what I did was pretty straightforward. I headed down to my usual spot, the gym, ’cause they’ve got a sauna there. My plan was to just do my regular 30-minute stint. No fancy stuff, just sit there, let the heat do its thing. I did make sure to wear my fitness watch, though. I was curious to see what my heart rate would get up to. I also made a mental note of how I felt before going in, just my usual self, not particularly tired or energetic.

The Sauna Sesh: 30 Minutes of Heat

Okay, so I got in. It was toasty, like a good sauna should be. The first ten minutes or so, I was just kinda settling in, feeling the warmth spread. Then the sweat started. Not just a little bit, but proper dripping sweat, you know? I glanced at my watch a few times. My heart rate was definitely climbing. It wasn’t like I was busting a gut on a treadmill, but it was for sure higher than if I was just chilling on my sofa watching TV. By the 20-minute mark, I was really feeling it. Just focusing on my breathing, trying to stay relaxed. The last ten minutes, I won’t lie, felt a bit long. Just counting down the minutes until I could get out and cool down. Ping! Thirty minutes done.

How I Felt Right After

Stepping out, I was, well, drenched. And hot. First thing I did was grab my water bottle and take a massive swig. I felt super relaxed, almost a bit floppy, if that makes sense. My skin was all red. But here’s the thing – did I feel like I’d just done a 30-minute workout? Nah, not really. My muscles weren’t aching in that good way they do after a run or lifting some weights. It was more like a deep, penetrating heat feeling, rather than a ‘worked muscle’ feeling.

Trying to Compare Apples and Oranges

So, let’s get back to the main question: what’s it equivalent to?

My heart rate in the sauna, it probably peaked around, say, 100 beats per minute, maybe a touch more. For me, that’s like a brisk walk. Not a super fast one, but a steady pace. If I go for a light jog, my heart rate’s definitely higher than that, maybe 120, 130. So, from a pure ‘making your heart pump’ angle, yeah, it’s doing something. It’s not nothing.

Then there’s the sweat. Man, I sweated a lot. Probably as much as if I’d done a pretty decent 30-minute cardio session. But sweating isn’t the whole story of exercise, is it? You sweat when you’re nervous too, doesn’t mean you’re getting fit.

What’s the Big Difference Then?

Here’s what I reckon is the main thing. When you exercise, like properly move your body, you’re working your muscles, you’re building strength, endurance. You get that feeling of your muscles having done some work. The sauna, it gets your heart rate up, it makes you sweat like crazy, but it’s more of a passive thing. Your body is reacting to the heat, trying to cool down. It’s not like you’re actively contracting muscles to move.

My Final Take on It

So, after going through it and thinking it over, what’s my verdict on this “30 minutes sauna equals X exercise” thing?

I’d say, honestly, it’s not a direct replacement for a proper workout. Not by a long shot. It doesn’t build your muscles, and I don’t think it really boosts your cardio fitness in the same way that, say, cycling or swimming would.

However! It definitely does something. Your heart works harder, you sweat out a bunch of… well, sweat. And it can feel pretty intense. For me, it’s more of a good way to relax, maybe help with recovery after a real workout, or just get those benefits of heat. So, if someone says it’s like a very, very light form of cardio stress, maybe similar to a slow stroll for your heart for a bit, I could kinda see that. But don’t go skipping your actual exercise thinking the sauna’s got you covered. It’s its own thing, with its own unique feelings and, I guess, some benefits. Just not a shortcut to fitness. That’s my two cents on it, anyway, from my own little trial.
