10 things you didn’t know about sweat

1| Hold the sriracha. Caffeinated beverages and spicy foods can make you sweatier. The extra sweat mixed with bacteria on your skin can lead to serious BO.

2| According to the journal Psychological Science, a person’s emotions can be transferred through exposure to body odors—also known as chemosignals—carried in sweat.

3| Humans have two types of sweat glands. Eccrine glands, found on the body’s surface, are activated by a rise in body temperature; they secrete mostly water and salt. Apocrine glands, located in areas abundant in hair follicles—like your pits and groin—get stirred up by emotional stress; they secrete more of an opaque fluid.

4| Excessive sweating—hyperhidrosis—afflicts 3% of the global population. The most common symptom? Super-sweaty hands, feet, and armpits. Treatment includes Botox, laser therapy, acupuncture, hypnosis, a gluten-free diet, and herbal remedies such as chamomile and valerian root. The wildest method may be iontophoresis, which blocks sweat glands with an electrical current.

5| Don’t bother “sweating it out.” Toxins can’t be excreted through sweat, so although sweat can contain trace amounts of certain toxins, the primary function of sweat is to cool the body, not detox it.

6| Not being able to sweat normally— anhidrosis—can be dangerous and lead to overheating and dehydration. Depending on the severity, the fix can include chugging liquids or rinsing off in a cool bath or shower.

7| Salirophilia is the sexual attraction to soiling or soiled things (which can include sweaty objects). There are plenty of websites dedicated to this fetish…or so we’ve been told.

8| A single sweat sample has been used to diagnose cystic fibrosis and can even track drug levels. Soon, wearables will be able to provide specific metrics via sweat ions that can help predict an athlete’s likelihood to become exhausted or injure muscles.

 9| Fitness guru Richard Simmons has helped millions of people shed millions of pounds through his Sweatin’ to the Oldies videos.

10| With about 1,000 varieties in North and Central America, sweat bees can be attracted to human sweat and are equipped with short tongues for lapping it up.
