Let's talk about power poses for confidence booster and how to use power poses body language to project mastery and confidence in yourself in everyday work situations.

It is the cheapest and least technological trick of life that you will find: The poses of power. It is the act of taking a position of trust, even when you don't feel sure of yourself, to make you look more dominant. 

Social psychologist Amy Cuddy got an excellent response when she gave a lecture during TEDGlobal 2012 on the scientific evidence behind the poses of power. His study showed that standing or sitting in a certain way (even for two minutes) increases testosterone levels and reduces the hormone cortisol, which is considered to be stress. 

These immediate changes in your body chemistry can affect the way you do your work and interact with other people. It could even have an impact on your odds of success.

First, we will go through the science of power poses. Next, we will divide what pose to use in seven common situations that affect your work success.

High-powered poses are about "opening up," says Coddy. Expand your body to take as much space as possible. This also works in the Animal Kingdom. When primates feel powerful, they grow their breasts to look bigger.

In humans, this happens in the same way. Studies show that even people born with blindness raise their V-shaped arms and lift their chin when they gain real competition.

In the meantime, people assume weak power positions when they feel vulnerable or defeated. They close, wrap their arms and shrink their knees. 

The poses of power produce significant and immediate changes in your body chemistry. After only two minutes in a power pose, your testosterone levels increase by 20%. They also cause your levels of cortisol, the stress hormone, to fall, allowing you to handle stressful situations better.

High power and low power poses tend to complement each other in individual interactions. One person is in charge, the other is not. Watch how Obama takes the space, while Joe Biden shrinks in his seat.

Now we will tell you "how to do power poses" in seven situations in the working world:

Sleeping: Sleep in an open position, with your legs stretched out.

Feeling great starts with the night before. It is time to forget the fetal position. Sleeping sideways with your arms and legs cramped towards the torso is considered a low-power position, says Cuddy. You can get up feeling sensitive and vulnerable without understanding why, which is not a good way to confront the competing job spaces. 

The alternative power pose is what we call the "Marissa Mayer," which makes you feel bigger and therefore more compelling. It's about putting your arms behind your head.

To speak at a meeting: Cross your arms over your chest and shoulder your back.

This posture can help you strengthen your argument in a meeting. The position of your shoulders in this position is key to model the way the observers interpret the crossed arms. If the shoulders are forward, the others will understand a sign of weakness, sending the signal that you are frightened. But if you roll your shoulders back and hold your head high, your arms folded become a sign of confidence. 

Cuddy says it's important to open your hands to fully extend your arm, taking up space, and not putting your elbow on the table. Women tend to bend their arms more than men. 

To close a deal: Put your hands on the table and lean forward:

When you find yourself in the last part of your presentation and preparing to give an offer, do this pose. Leaning forward while standing still demonstrates that you are in a dominant position. 

For interviews: Plant your feet openly and raise your arms in the shape of a V.

Making this pose of power in the interviewer's office can be taken as offensive, says Cuddy; But there is an alternative, which she calls "The Performer" in honor of Mick Jagger. 

Before the interview, throw your arms in the air and expand, as if you were receiving the applause at a concert. Do it in the elevator or on the stairs when you are going to the office, or to the bathroom before entering the reception. Hold the pose for two minutes and work on those hormonal changes that will give you the confidence you need in the interview.

To do interviews: Rest your arm on the back of your chair, keep your knees apart and rest.

This is the best way to demonstrate your confidence and comfort level when interviewing a candidate. This pose, a little less open than the "Obama," emphasizes opening the body while keeping your feet on the ground. Cuddy calls this pose "The CEO" after seeing a photo of Oprah Winfrey looking like a real boss. 

Variations include putting your hands behind your head and resting a heel on your knee. 

To talk to your boss: Draw your chest, plant your hands on your hip and open your feet a little. 

When your boss joins the line of the coffee machine, you might get nervous thinking about better conversations than "How's your weekend?" 
Channel your favorite superheroine and apply the "Wonder Woman" pose. Raise your chin to maximize your power. This pose has the opposite effect of touching your neck, which suggests anxiety and lack of control, which is considered as the lowest power pose.
