New Research Reveals Sweat Is Not the Ultimate Indicator of Intensity During Exercise
A common notion that those who leave fitness classes looking drenched must have worked harder than their fitter counterparts is not entirely accurate. According to Adam Collins, a researcher at the University of Bath's Centre for Nutrition, Exercise and Metabolism, sweat levels do not always correlate with the intensity of exercise.
While it's true that intense workouts generate more heat, which can lead to increased sweating, there are numerous other factors at play that influence how much you sweat. Temperature, clothing, humidity, fitness level, age, sex, body size, and even climate acclimatisation all contribute to varying sweat levels.
In fact, Collins notes that individuals may sweat heavily during an easy run on a hot day, yet barely break a sweat on a cold day when they're pushing themselves at a high intensity. This highlights the complex nature of thermoregulation, which is the process by which your body regulates its temperature in response to changes.
Sweat itself serves as a marker of dehydration rather than a reliable indicator of how hard you've worked out. Other more accurate measures include breathing rate, perceived exertion, and heart rate, which can be tracked with wearable devices or fitness monitors.
So, the next time you're tracking your workout intensity, don't rely solely on sweat levels – instead, take a closer look at your body's other vital signs to get an accurate reading of how hard you've pushed yourself.

I gotta say, this is super interesting! I used to think that if I was dripping wet after a workout, it must mean I killed it in the gym 
but now I'm thinking it's so much more complex than that. Like, have you ever been on a really hot day and just managed to make it through an easy run? Yeah, you sweat buckets! But maybe your body is just trying to cool down or something? 
Anyways, I love that we're learning more about how our bodies work and can start making more informed decisions about our fitness routines. Wearable devices are the way forward for me! 
! I mean, who hasn't been that sweaty during a workout only to later find out they didn't even give it their all? It's like, our bodies are super smart and can trick us into thinking we're doing more than we actually are. It's all about understanding how our bodies work and not just relying on sweat levels as a measure of intensity.
I knew that sweat was just a myth perpetuated by gym bros everywhere! Who needs all that extra stress when you can just overheat and blame it on the exercise? 
It's not about how much you sweat, it's about how your body is really feeling – so ditch the sweat levels and grab those wearable devices. I mean, let's be real, who doesn't love tracking their breathing rate and heart rate like some kind of fitness robot? 
But seriously, this research is actually pretty cool – thermoregulation is a wild beast, and it's interesting to see all the factors that influence sweat levels. Maybe next thing you know, we'll be able to calculate our exact caloric burn based on the number of selfies taken during the workout... 
. Our bodies are super efficient at regulating temperature and all that jazz 
. Like, if we're not drinking enough water before or after our workouts, we'll sweat more regardless of how intense it is 
.
. Thanks for sharing this info, I feel like I learned something new 
!
! As a parent who's been trying to get my kids to exercise more (aka guilt-tripping them into joining sports teams), it's frustrating when we can't even rely on sweat levels as an indicator of intensity. Like, what if they've just had a hot shower or are wearing super absorbent workout clothes? 
And don't even get me started on the whole "sweat is just a marker of dehydration" thing... how am I supposed to know that?! 
Not sweaty just yet! 
. It just goes to show that our bodies are way more complicated than we think 
.
at least I'm trying
but it's not as simple as thinking "oh they must have worked way harder than me"
