Sweating: The Misleading Indicator of Hard Workouts
It's widely assumed that the more you sweat during a workout, the harder you've pushed yourself. However, research suggests this isn't always the case. According to Adam Collins, a researcher at the University of Bath's Centre for Nutrition, Exercise and Metabolism, sweating is simply a byproduct of thermoregulation – the process of regulating your body temperature.
When exercising, the energy produced fuels activity, generating heat as a byproduct. The more intense the workout, the greater the heat generated, leading to increased sweating. But Collins notes that sweat levels are not always an accurate indicator of exertion. Environmental factors like temperature and humidity also play a significant role in sweat production.
In hot, humid conditions, even low-intensity exercises can lead to excessive sweating due to reduced evaporation efficiency. Conversely, on cold days, high-intensity workouts may result in minimal sweat production despite intense effort.
Individual variations also impact sweat levels. Fitness level, age, sex, body size, and acclimatization to the climate all contribute to individual differences in sweat response. So, while sweat can be a good indicator of dehydration, it's not a reliable measure of hard work. Better indicators include breathlessness, perceived effort, and heart rate – which can be tracked with fitness trackers or smartwatches.
While sweat may not accurately gauge workout intensity, it does indicate hydration levels. If you're left dripping after a session, it's essential to replenish fluids.

I always thought if u were sweaty u must be doing an intense workout but apparently its not that simple... like what even is the point of sweating if its not even a good indicator? 
, but then I read that research article and it makes total sense now. Like, if you're not even breaking a sweat at first, but still getting the same level of tiredness as someone who's been running for like an hour, then maybe they just need to work on their hydration game, right? 
I guess what it means is that sweat isn't as black-and-white of an indicator as we thought, so maybe we should be looking at other signs of exertion too. Like, when was the last time you checked your heart rate or breathing to see if you're pushing yourself hard enough? 
It's actually super misleading! The environment and individual factors have way more of an impact on sweat levels than actual effort. Like, I've been to hot yoga classes where I'm sweating buckets but my friend is over there struggling to catch her breath... guess who's been doing more actual work out? 
. Like, I get that our bodies produce heat when we exercise and that sweating is just a way for us to cool down, but it's not exactly an accurate measure of how hard we're pushing ourselves. Environmental factors like temperature and humidity can totally throw off the sweat levels, and individual variations in fitness level and acclimatization make it super unreliable 
. And hey, if you do end up dripping wet after a session, at least you know you need to refuel with some water 
... but it turns out that's not even close to true 
. I mean, environmental factors are SO big in sweat production – like, have u ever gone for a hike on a super hot day and just lost all your cool? 
No wonder u're sweating buckets, but maybe u weren't even pushing yourself that hard 
. Use ur fitness tracker or smartwatch instead 
, but if we take sweat as an indicator of how hard we're working out, that just doesn't add up, you know? Like, I remember doing a session at the gym and I was literally dripping wet, but it wasn't even that intense... just a casual jog on the treadmill. I think my body temperature must've just gotten outta whack or something 
, whereas me? I'm like a walking sweat factory 
) and I'm doing low-intensity yoga, I get super sweaty 
Can't we just move on from this outdated idea that more sweat means you're pushing yourself harder? 
And don't even get me started on how annoying it is when fitness trackers start telling you to "push through the pain" just because your heart rate is a bit higher than usual...
