Hydration: The Flip Side of Sweat

For many athletes, sweating feels uncomfortable, though SweatHawg products can certainly help with that (our mission in life).

But sweating is of course essential, your body relies on evaporative cooling as the primary mechanism to decrease surface body temperature and prevent overheating.

During activities in the heat, the cardiovascular system works overtime in order to provide blood to the working muscles, as well as increase blood flow to the skin for cooling. Unfortunately, if one area of the body is receiving less blood than needed, performance will be compromised.

While the temperatures may be similar in two different regions of the country, relative humidity is the most important factor having a direct relationship to sweating and cooling, as relative humidity determines evaporation rates.

The lucky athletes are those who train in areas of low humidity and welcome a nice breeze to keep the body from overheating. As for athletes training in high humidity, they are all too familiar with wet clothes and high heart rates during the first ten minutes of training outdoors.

How Much Should You Drink?

If you consume too much water and not enough electrolytes, your body pulls electrolytes from its cells in order to create the right balance for absorption. If you consume too many electrolytes and not enough fluid, your body pulls fluids from within to create the right balance for absorption.

Electrolytes modulate fluid exchanges between the body's fluid compartments and promote the exchange of nutrients and waste products between cells and the external fluid environment.

Heat may cause athletes to lose up to .5-4 L/hr of sweat, depending on body size (surface area), training environment, diet and ability to meet hydration and electrolyte needs. Hydration guidelines are not designed to replace all the fluid you lose while out sweating, but most of it. When you know your sweat rate, you can then aim to hydrate accordingly.

An optimal hydration solution is necessary in order to meet individual calorie and electrolyte needs, so choose carefully. Remember, liquid calories are essential in ensuring a successful performance

Your Sweat Rate Test

Our awesome customer base is made up of folks all at least “above average” in the sweat rate test. Our kind of people!  Anyway, here’s the nitty gritty on sweat rates. We have what you need to keep sweat from your eyes, regardless :-)

Eventually we will get to the flip side~hydration.

Average and Champion Sweat Rates

How much do we sweat? An average person sweats between 0.8 to 1.4 liters (roughly 27.4 to 47.3 oz.) per hour during exercise. To help you with a visual, the smaller bike water bottles typically hold 0.6 liters (20 oz.) of fluid and the larger bottles hold 0.7 liters (24 oz.) of fluid.

The highest recorded sweat rate for an athlete in an exercise situation is 3.7 liters (125 oz.) per hour, recorded by Alberto Salazar while preparing for the 1984 Summer Olympics. The highest human sweat rate recorded is 5 liters (169 oz.) per hour measured on a resting body exposed to a hot environment. At rest, the skin blood flow was maximum and not competing with exercising muscles.

How do you know if you are just an average sweaty person or a truly champion sweater? You need to do some testing.

Your Sweat Rate Test

The easiest way to measure your sweat rate is to weigh your naked self before exercising for one hour. After an hour of exercise, return home, strip down and weigh yourself again. Assuming you did not use the toilet or consume any fluids during exercise, your weight loss is your sweat rate. For each kilogram of lost weight, you lost one liter of fluid. (For each pound lost, you lost 15.4 oz. of fluid.)

If you drink any fluids or use the rest room between the two weight samples, you'll need to include both of these estimated weights in your calculations. Add fluid consumed to the amount of weight lost. Subtract estimated bodily void weight from the total weight lost.

Be sure to record the heat and humidity conditions in your sweat test. Repeat the test in cool and hot conditions. Repeat the test for swimming, running and cycling because sweat rates will vary for each sport and vary with environmental conditions.

Now that you know your sweat rates in each sport, you probably imagine that simply drinking enough fluid will replace what you lose to sweat given the environmental situation. If it were only that easy.

The Strange Brain of the World’s Greatest Solo Climber

Great story about the ultimate “no sweat” free solo climber Alex Honnold (nickname “No Big Deal”). Turns out his brain does not register fear. Helps him do things like climb El Capitan this summer solo no rope in 3 1/2 hours. Comment at the summit? “That was rad!”  
Meanwhile, to keep sweat from eyes and glasses the rest of us can count on SweatHawg Headwear. Pretty rad too.

New Products Help Beat The Heat

New Products Help Athletes & Workers Beat the Heat: Oregon Start-up SweatHawg Launches Sweat Control Headwear Line

Sisters, Oregon

“If you’ve ever had a problem with sweat running into your eyes or glasses while working or playing hard, we’ve got the best solution,” says company founder John Rahm, who came up with the SweatHawg helmet liner when he couldn’t find bike headwear that would fit invisibly in his helmet and stop sweat from staining his glasses. 

(August 28, 2012) – Bringing hope to active people who sweat like beasts, SweatHawg, an Oregon start-up company, has launched a line of innovative head sweat control products.  In time for Labor Day, the first is a helmet liner, promising relief for anyone who wears a helmet and sweats more than average.

Sweat production during exercise ranges between a quart and a gallon per hour, and Rahm is one of many at the heavy end of the range.  Noting recent record-setting heat waves and other trends, Rahm anticipates demand for his next-generation sweat control headwear solution to grow, among outdoor laborers as well as athletes:  

–Approximately six million hard hats are sold in the U.S. annually.

–In 1977, Americans took 1.27 million trips by bike; by 2009 this number had more than tripled to 4.08 million.

–Along with the growth in cycling is a growing need for UV protection in an aging population.  Men in their forties have a 40 percent incidence of male pattern baldness, in their fifties a 50 percent incidence, etc.  And cycling helmets leave gaps where the sun beats down on bare heads.

With its flagship helmet liner product selling briskly—the 500th unit is expected to ship soon—SweatHawg will introduce a head sweat band later this fall, bringing its patent-pending head sweat control technology to runners, tennis players and other athletes.


SweatHawg helmet liners and head bands are a sweat-wicking, hyper-absorbent solution to the problem of sweat in the eyes.  Made in America with imported ultra absorbent fabric, SweatHawgs are a new approach to managing head sweat, outperforming gutter systems and even your favorite bandanna.  Satisfaction guaranteed, or your money back.

Get a SweatHawg Headband for your favorite tennis player.

Of course, tennis players suffer from dripping sweat.
A survey on the Tennis Warehouse website indicates that the most popular solution among tennis players is the headband at 41%, and if you throw in the bandanna people at 19%, that comes to 60%!
There is some desperate creativity as well, visors on backwards, and hats PLUS headbands. Whatever works : -)
Our stuff works, better than anything else, guaranteed, uniquely combining ultra absorbent and highly wicking fabrics.

Go get a SweatHawg headband for your favorite tennis player.

Whatabout SweatHawg X2?

SweatHawg now offers double-absorbency versions of most of our sweat control products, helmet liners, skull caps, and headbands. And we have the hardhat sweat bands, which were double from the start. 

While the single layer helmet liner we first offered solo in 2011 was immediately the most effective sweat management product available, we have been gratefully accepting suggestions from product users ever since. 

Early on, a pro reviewer from Bike Rumor tested our helmet liners in both dry and humid climates. 

Though he loved the drip-free performance in SoCal, back home in humid Illinois, an hour into his ride the dripping began. Based on this feedback, we doubled the absorbent layer and created the X2 helmet liner. Problem solved... no sweat :-) Read review here.

This year we added X2 versions of the headband and the skull cap. We'll keep the sweat out of your eyes and glasses, no matter where you ride...or run or skate or climb or walk or work.

The Easy Way to Make Your Own Sports Drink

No praise for pricey powders...water, sugar, and a bit of salt blind-tested better...

Pop quiz: You’re kitting up and getting ready to hit the road with your crew for a Saturday morning ride. You open the pantry and crack open the tub of sports drink mix to discover—d'oh!—a mere dusting of mix remains. Do you: A) Get to the shop in time to buy a few portable drink mix sleeves or tabs? B) Ask the bunch to swing by 7-11 on the way out of town so you can grab a bottle of something blue and sugary for the ride? C) Say screw it, and hit the road on water alone?

How about D) None of the above. Here’s an über-easy option few of us consider that is now scientifically proven to work just as well as, if not better than, your standard sports drink: Put some sugar in your water.
