Hand gestures while talking are a powerful aspect of communication.
A study analyzing TED Talks found viral speakers used nearly twice as many hand gestures as the least popular speakers. People who "talk" with their hands tend to be seen as warm, agreeable and energetic. The less animated are viewed as logical, cold and analytical.

Hand gestures are healthy and normal

We collect information from others' body language. We naturally feel that passionate people will be more animated and look more enthusiastic. When their gestures are bigger, we process that they must be really passionate about their topic.
This is mostly because body language is vital in helping to communicate our emotions and motivations.

Gesturing helps you understand other people

Hand motions often reveal information that is absent from our talk. It might signal that a point is more important, or that the speaker is still trying to understand an idea.
According to a study published, children that use hand gestures early in life is likely to develop a strong vocabulary and other skills related to sentence structure and better storytelling.

Benefits of hand gestures

A mismatch occurs when we signal something with our hands that is different from our words. It may be a sign that you're learning.
Adults are less likely to trust people who display a mismatch between speech and body language.

If someone has ever made fun of you for making elaborate hand gestures while talking — or you’ve seen footage of yourself speaking, only to be horrified by your flailing forearms — don’t be too concerned.

According to psychologists, those gestures probably are helping you express your thoughts more effectively.

That being said, of course, itis possible for your gesturing to get a little out of hand (pun intended). Here’s a cautionary tale from GOP presidential candidate Ohio Gov. John Kasich, courtesy of “The Daily Show”:

Kasich-level ninja hands aside, gesturing is a healthy and normal aspect of human communication. Here’s what we know about the psychology of why we use our hands to “talk.”

Our bodies play an important role in the way we think.

Hand gestures help us take what’s in our mind and make it intelligible to others.

“Gesture is really linked to speech, and gesturing while you talk can really power up your thinking,” Kinsey Goman said. “Gesturing can help people form clearer thoughts, speak in tighter sentences and use more declarative language.”

A brain region known as the Broca’s area is at least partly responsible for this. It’s connected to speech production, but is also active when we wave our hands, according to Kinsey Goman.

Gesturing helps you understand other people.

We gather information from others’ body language, as well as from their specific words. Hand gestures often underscore the important points someone is making.

“On the receiving end, a lot of this is processed subconsciously,” Kinsey Goman said. “You may not be aware of the connections, but you instinctively feel that when someone is more passionate, their gestures automatically become more animated and they look more enthusiastic. You’re processing that their gestures are bigger, so they must be really into this topic.”

This is largely because body language is crucial in helping communicate our emotions and motivations to others.

“We have an emotion, our body responds, and then we speak,” Kinsey Goman said. “The body responds first. What is really being communicated is the underlying emotion and motivation — how you’re really feeling about something.”

Gesturing can act as a “second language.”

Hand motions can reveal information that may be absent in our speech. For instance, a gesture might signal that a certain point is more important than others, or that the speaker is still wrapping his or her head around an idea.

“Research demonstrates that the movements we make with our hands when we talk constitute a kind of second language, adding information that’s absent from our words,” <a data-rapid-parsed="slk" data-rapid_p="11" data-v9y="0" data-ylk="subsec:paragraph;cpos:18;elm:context_link;itc:0" dir="ltr" href="http://www.businessinsider.com/hand-gestures-reveal-complex-thoughts-2013-6">Annie Murphy Paul, author of Brilliant: The New Science of Smart , wrote in Business Insider. </a>“It’s learning’s secret code: Gesture reveals what we know. It reveals what we don’t know.”

These motions are a healthy part of child development.

Using hand gestures early in life can predict that a child will later develop a strong vocabulary, as well as skills related to sentence structure and storytelling, according to a <a data-rapid-parsed="slk" data-rapid_p="12" data-v9y="0" data-ylk="subsec:paragraph;cpos:20;elm:context_link;itc:0" dir="ltr" href="https://goldin-meadow-lab.uchicago.edu/sites/goldin-meadow-lab.uchicago.edu/files/uploads/PDFs/2014_Demir_SL_SGM.pdf">study published last year in the Journal of Child Language. </a>

The children’s ability to structure a narrative improved over this time period — and children who had expressed a character’s viewpoint using hand gestures at age 5 were more likely to tell better-structured stories later in childhood.

Our gestures and our speech don’t always match up.

Usually, our hand movements work together with our speech to convey a point — but this isn’t always the case.

“Gesture-speech mismatches” occur when we convey something with our hands that doesn’t seem to match up with what we’re saying. Depending on your age, this may be a sign that you’re learning, according to University of Chicago psychologist Dr. Susan Golden-Meadow.

“Children who produce gesture-speech mismatches on a task may have information relevant to solving the task literally at their fingertips and could, as a result, be on the cusp of learning how to solve that task,” <a data-rapid-parsed="slk" data-rapid_p="13" data-v9y="0" data-ylk="subsec:paragraph;cpos:25;elm:context_link;itc:0" dir="ltr" href="http://www-cogsci.ucsd.edu/~coulson/Courses/101c/Articles/goldin-meadow.pdf">she wrote in a 2006 paper published in the journal Current Directions in Psychological Science </a>.
