This spike came 10 hours after painting their nails.</p><p>Not much is known about the chemical&#39;s effects on humans, though. A study using animals did link TPHP to reproductive and developmental issues, but it&#39;s still too soon to say if that applies to people.</p><p><i>This video includes images from Getty Images.&nbsp;</i></p>
