DENVER -- Did you catch Donald Trump's sniffing and deep breathing during Sunday's second presidential debate? What about Hillary Clinton's smirks and wide eyes?
Denver body language expert Traci Brown said both gestures say a lot about each presidential candidate.
"Reading body language is key to understanding the truth behind the words," she said.
Brown has more than 15 years of experience and helps train executives on how to use their body language strategically.
Despite his loud breathing, she said Trump didn't have a cold or need a Kleenex.
"Whenever someone takes a big deep breath through their nose they're about to go on the attack," said Brown. "Cops are trained to look for this when people maybe just about to attack physically but guess what -- it's the same when they're attacking with their words."
She said it's a deeply unconscious gesture and points to when Trump did it during the debate.
"It came immediately before a direct attack on Hillary," said Brown.
In most cases, Denver7 found her statement to be true.
"Hillary constantly talking about the inner cities of our country [Trump takes a deep breath] which are a disaster," Trump said during the debate.
"[Trump takes a deep breath] I think it's disgraceful, I think she should be ashamed of herself," Trump said while talking about Bill Clinton's prior transgressions.
Brown also addressed Hillary's smirks and wide eyes.
"Those are signs of contempt," she said. "Moral superiority so she thinks that she is far above Trump as far as the things that she believes.
Brown said both candidates played well to their bases during the second debate, but has this advice if they want to reach undecided voters.
"Hillary could be more animated and Trump could tone it down that way they're going to get those people who are in the middle, those people who haven't made the decision yet," she said.
