Many people worry that they have to be extroverted to use body language. But this is far from the truth! Introverts can master body language and nonverbal behavior to strengthen their interactions and gain confidence.

Here are a few tips for introverts:

1. Body Language And Emotions

Body language is not just about how you appear on the outside. It is also about how you feel. Researcher Amy Cuddy from Harvard Business School found that standing in power poses for five minutes can increase your testosterone, the power hormone and lower your cortisol, the stress hormone. So changing your body to be more powerful not only helps other people see you as powerful and confident, but also makes you feel more powerful and confident.

2. Take Up Space

One of the basic concepts of Power Posing is to take up more space in your environment. This helps you claim territory and assert your confidence. So instead of crossing your legs or tucking in your shoulders and head, try being expansive. Keep your head high, your shoulders loose, sit larger in your chair and walk with long strides.

3. Don’t Cross Your Arms

Defeated or low power poses lower your testosterone levels and increase your stress hormone cortisol. So avoid crossing your arms and tightly crossing your legs. Keep your trunk wide open to people around you. Remember, this shows you are approachable to others and keeps you in a more open-minded attitude.

4. Don’t Check Your Phone When You Are Nervous

Introverts tend to check their phone when they are nervous, but this puts you right into defeated body language. So try to avoid checking your phone when you want to feel confident and again try to relax and be expansive. I know someone who carries a newspaper around with him because that is an easier way to take up space.

5. Use the Triple Nod

The triple nod is the non-verbal equivalent of the ellipses. It is a nonverbal cue for someone to keep talking. If you are introverted and aren’t great at making conversations, you want to encourage the person you are speaking with to keep talking. Once they are done speaking and pause, nod three times in quick succession and they will often continue. If not, you can pick up where the conversation left off, but this is a great way of showing engagement and lengthening a discussion.

Simply being aware and wanting more open body language can help you engage people and have better connections.

As someone who frequently writes and edits tech content for SUCCESS, I have a simple meter for how market domination works: if my mom uses or understands it, then it has a chance at becoming wildly successful. My 65-year-old mom became active on Facebook in 2009, around the same time it surpassed MySpace as the leading online social network in the United States. She also got an iPad right before Apple’s most successful selling period of the device, in the first quarter of 2013. Coincidence?

Of course, I’m (half-) joking, but smartphones and similar devices are certainly ubiquitous, even to my dear mother who used to have difficulty double-clicking. And while we have telephone etiquette and email etiquette, the parameters for social media or smartphone etiquette aren’t as clearly defined.

So as we approach the season of holiday parties and family gatherings, you might want to consider this infographic by eBay Deals on smartphone etiquette—what’s considered acceptable (or not acceptable), depending on age group, event and situation.

From unsurprising ambiguity on smartphone usage in the workplace to a surprisingly high percentage of people who approve of texting behind the wheel at the red light, the results are fascinating. I don’t know if I agree with all of the infographic’s findings, but I’m definitely introducing the phrase “phubbing” (short for phone-snubbing, or neglecting people in real life in favor of your smart phone) to my mom to see if it catches on.

What about you? Do you agree or disagree with the smartphone etiquette rules below?
