Another rivulet of sweat runs down your neck as your usual run turns into a seriously sweaty workout on this hot and humid day. You think to yourself that one of the great things about summer is all these extra calories you're burning because it's so danged hot out!

After all, sweaty workout equals a slimming one, right? Umm…don't break out the double raspberry swirl gelato yet. Take our quiz below and find out which sweat myths you can ditch.

True or False? See if You Can Tell The Sweat Myths from the Truths


True or False?: You sweat all the time.
True. You are always releasing moisture from your skin to help regulate body temperature, although usually not enough to be noticed. And this is taking place over almost the entire surface area of your body.

T/F?: The most that a human can sweat is three liters per day.
False. This is one of the most common sweat myths! A person in a colder climate can sweat up to a liter per hour! A person in a warmer clime can lose between two to three liters per hour.

T/F?: You burn more calories during a hot weather workout.
True. Your heart needs to work harder to both keep your muscles well oxygenated during cardio and to send extra blood to the surface of your skin to keep your body temperature safe. Unfortunately, the calorie numbers are pretty low, so don't think you've earned an ice cream sundae! Think more like one bite of chocolate.

T/F?: Sunblock makes it harder to sweat.
False. Don't let sweat myths like these keep you from being sun safe. "Sunscreen does not affect the sweating mechanism, which is your body's way of cooling itself," says dermatologist Brooke Jackson, M.D., of the Skin Wellness Center of Chicago. Please note that no sunblock is truly "waterproof or sweatproof" so make sure you reapply every two hours.

T/F?: Sports drinks really do make a difference.
True. But only in moderation. When you're sweating heavily you lose electrolytes which need to be replaced through food or drink. Sports drinks can be a quick way of doing that, but keep in mind that sports drinks are often fairly high in calories.  Make sure you don't drink down empty calories that you just got rid of with a hard workout!

T/F?: Your body works harder when it's humid.
True. Your skin relies on the air being somewhat dry so that the moisture from our body can easily evaporate. In humid conditions, the air is saturated with moisture and that makes it harder for the sweat to evaporate. This keeps your body temperature elevated and is why it can feel like such a struggle to do even easy workouts in humid conditions.

Keep cool during hot-weather workouts: Wear light layers that can breathe and rely on light colors (this is not one of the sweat myths!). We love these keep-you-cool workout skirts.

Favorite tip: Soak your favorite baseball cap in cool water before you head out. Works like a charm to keep you cool.
