The adrenaline and anxiety of making your way through airport security could end up setting off a surprising and potentially embarrassing reason for an extra screening or pat down.  Here's what the TSA says can cause a false alarm on body scanners.

Travelers passing through airport security may be flagged for additional screening due to excessive sweat in the groin area. The Transportation Security Administration (TSA) has stated that body scanners can be triggered by moisture, as electromagnetic waves used in the scanners react to sweat. 

To avoid unnecessary delays, travelers are advised to avoid arriving at security checkpoints while excessively sweaty, particularly after physical exertion. Using appropriate deodorant may also help reduce the likelihood of being flagged during screening.

This one thing could get you flagged by TSA

People are getting flagged at TSA for this embarrassing reason. As if airport security wasn't already stressful enough, while most of us sweat up here, it's the sweat down here that could get you flagged for extra screening. The TSA has confirmed that excessive sweat in your groin area can set off the body scanner, something to do with how the electromagnetic waves bounce off moisture. So maybe don't sprint to your gates soaked in sweat, or better yet, pack deodorant that covers all of the bases.
