Why Do I Sweat So Much When I Exercise? Here’s What You Need To Know


You're halfway through hot yoga, and you can barely see because of the aggressive, blinding stream of sweat pouring down your face.

Meanwhile, your friend next to you is almost completely dry and sweat-free.


Everyone sweats at least a little when they work out (and honestly, if you're the type that can tear through cardio with a mere casual, moist glow, I envy you).

But what's up with the people (such as myself) who tend to feel like they just bathed in their own salty sweat when they exercise?

Elite Daily spoke with Dr. Anthony Balduzzi, founder of the Fit Father Project, to get a better understanding of the science behind your sweat.

He explains,

OK, simple enough -- sweat is not only natural, but necessary when it comes to working out.

But still, why do I always look like Ryan Gosling in that torrential downpour scene from The Notebook after I step off the StairMaster?

Here are five possible reasons why you feel like you're sweating a ton when you exercise.

1. Your Overall Body Size

Dr. Balduzzi tells Elite Daily,

Bottom line: If you have a smaller frame, you will sweat less than your larger gym partners -- even if you're both doing the same workout.

2. The Room Temperature

This might seem obvious, but hot yoga is going to make you sweat a lot more than, say, figure skating.

Dr. Balduzzi says it's important to remember that sweat is your body's main evaporative cooling system -- kind of like an internal fan. 

He explains,

 Alight I'm taking my next workout to the Rockies -- who's with me?

3. The Climate You Were Raised In

Dr. Balduzzi tells Elite Daily every human is born with a virtually identical number of sweat glands.

Yet, not all of these sweat glands are actually able to produce sweat:

And the activity of your sweat glands is largely determined by the climate in which you were raised as a child.

People who grew up in very warm climates typically have a higher percentage of mature, active sweat glands, whereas if those who grew up in a colder climate had less of a need to produce lots of sweat in early childhood to stay cool.

Dr. Balduzzi adds,

Dope. Thanks a lot, Mom and Dad.

4. You May Have A Condition Called Hyperhidrosis

Hyperhidrosis is a condition characterized by excessive sweating, and it affects an estimated 7.8 million Americans.

The condition can be due to an underlying health condition, or it can simply have no cause at all.

If you're not sure about your symptoms, contact your doctor to try to rule out any underlying conditions.

Also, keep in mind that the symptoms of excessive sweating can be effectively treated with proper medical care.

So don't sweat it. Ha. Ha. Ha. OK, bye.

5. TBH, You Might Just Be In Really Good Shape

Studies say sweating a lot may simply be a sign that you're in amazing shape.

I like the sound of that (maybe not the smell, though).

Plus, research suggests that endurance athletes sweat sooner and perspire more in comparison to those who don't train quite as hard on a regular basis.

Basically, the more fit you are, the easier it is for your body to sweat.

When it comes down to it, Dr. Balduzzi says, if you're the type of person who sweats a lot, it's really nothing to fret about:

Sweat on, baby, sweat on.
