WHEN WAS THE LAST TIME YOU PERSPIRED?

We're not talking about that moistened-forehead thing from too much hot sauce on your taco, but a full-body torrent of sweat from a normal everyday workout. Did it feel like you were wrapped in a plastic trash bag?

Actually, perpiration is your body's temperature management system in action. When the air around you is too hot to let body heat simply radiate into the atmosphere, your body uses another method to cool itself - it sweats.

When you sweat, heat dissipates through your skin in the form of moisture. When this moisture evaporates, it speeds the removal of heat and helps prevent your body's core temperature from becoming too high.

There are a couple of problems with this system. The first is that when you perspire, essential fluids and electrolytes like sodium, potassium and chlorides, which are needed for proper cellular function are lost. This leads to dehydration.

The second problem is your normal workout gear. It's like wearing a mobile sauna. It traps the moisture and prevents cooling and drying. This keeps your body's temperature management system from working as efficiently as it should. As a result, your body has to work harder to cool itself, using more energy, and actually increasing the production of perspiration.

Both situations relate directly to the amount of energy remaining for your body to perform at its peak. If you want more energy, you've got to increase the efficiency of the cooling process. And that's easy with McDavid InteraWear^TM. Engineered specifically to act as a moisture transport device, InteraWear^TM literally increases the body's temperature management efficiency, and helps you perform better. At any sport. In any season.
