It is very essential to have the ability to read and understand another person's body language. Listening only to the words the other person is saying is not always enough. His or her body language can always tell if that person is being honest in what she is saying and what she really feels deep inside.
Body language entails the gestures and movements involving the body, from head to foot. Each signal of body language may have different meanings, depending on the situation in which it was delivered.
Head
You can signal yes or no by the movement of the head. Nodding usually means “yes” or “I agree”. But in other countries such as Yugoslavia and Turkey, it sometimes means “no”.
Tilting the head backwards or to the side indicates that the person is thinking deeply or considering a though or idea.
Face (Eyes, Nose, Lips)
Facial expressions are obvious visible signs of how someone truly feels, however there are some people who have practiced to take control of their facial expressions by making them somewhat expressionless or passive.
Even with an inexpressive face, nobody could miss what is being expressed through the eyes. The eyes can speak volumes given any circumstance. Eye contact is a strong indication of focus of attention, interest, attraction, and honesty. You can spot somebody lying to you if he or she cannot hold an eye contact for a period of time. When the eyes would look away, it signifies lack of interest, dishonesty, and boredom. But there are times when looking away signifies attraction or simply an occurrence of a slight distraction, for as long as the person will look back to the person he is talking to.
Touching or rubbing the nose is one of the most common self-touching gestures, which is usually done by people who are lying or trying to hide something. Blowing of the nose is a gesture seen as rude by most countries, but it is considered as healthy in some countries in Asia.
Licking or biting the lips is one of the typical signals of flirting done by women. Kissing is a gesture to show one's affection, and also used as a form of greeting. But there are conservative countries, particularly in Asia, which do not allow public display of affection such as kissing. And in some cultures like in the Philippines and Puerto Rico, the lips are used for pointing instead of the finger.
Arms And Hands
There are plenty different hand gestures, and each one has different meanings. The most common hand gestures are hands-in-the-pocket, arms crossed over the chest, hands on the waist, and handshakes. The first one may indicate nervousness or lack of interest. Crossing the arms signifies a defensive posture, and it may also mean doubt or suspicion of what the other person is saying. The hands on the waist may indicate anger or fury, but men also do this to show their masculinity. A handshake, meanwhile, is a form of greeting in most countries.
Legs And Feet
Crossing the legs are done by most people, especially women. Most of the time, it is done as a comfortable position. However, there are countries that regard this action as rude.
The Misuse Of The Ability
The ability of reading someone's body gestures sometimes is not reliable. The gestures performed by a person that are regarded as rude by other people maybe just habits of that person without the intention of being rude.
