When you’re training hard and your body is pouring sweat, you’re doing more than drenching your workout attire — you’re losing fluids and electrolytes. Neglecting to replenish the lost duo can lead to sluggishness and diminished performance. Not good, especially when you’re trying to stay a step ahead of the competition. So whether you’re about to train, in the midst of a training session, or you’re simply in need of an energy boost, look to P4’s Energy Formula. Why Energy Formula? It’s a potent and delicious workout supplement that can provide you with branched-chain amino acids (BCAAs), carbohydrates, caffeine, a vitamin matrix, and electrolytes that’ll aid you in your quest to keep electrolyte and energy levels up even as the temperatures skyrockets and the sweat continues to waterfall down your body. (Also, for a delicious post-workout drink that’ll keep electrolytes and hydration levels amped, try P4’s Grape Recovery Push Formula.)

But since sweating is something you do every time you gym it up, it pays to know a handful of facts about it, such as …

1. Humans have between two and four million sweat glands that are produced from the eccrine and apocrine sweat glands; the former is found on the body’s surface and are activated by a rise in body temp; the latter is located in areas that are abundant with hair, mainly the armpits and groin.

2. Sweat doesn’t stink, but when sweat mixes with bacteria on your skin—and it’s on everyone’s skin at all times—that’s when B.O is produced.

3. When you’re told to “sweat it out” you’re not doing yourself any good. Sweat only contains minimal amounts of toxins.

4. The primary function of sweat is to cool the body down and to prevent you from overheating.

5. According to WebMD, everyone sweats but for different reasons. Heat and humidity could trigger sweat, but spicy foods and strong emotional responses have the ability to make you sweat as well.

6. Sweat is not a benchmark for how hard you’re working or how many calories you’re burning during exercise.

7. Too much or excessive sweating is known as hyperhidrosis. The most common symptom? Incredibly sweaty hands, feet, and armpits. The good news: a very small percentage of the population is afflicted with hyperhidrosis.

8. As your fitness level improves it should take you longer to sweat, according to Jenny Scott NASM-CPT. The reason being: your core body temperature should take longer to increase.
