Body Language of Shallow Breathing

No picCue: Shallow Breathing

Synonym(s): Hyperventilating, Shallow Breathing, Panting.

Description: An unusually high and quick rate of respiration.

In One Sentence: Shallow breathing indicates a high level of physical or emotional arousal.

How To Use it: Use shallow breathing to prepare for the flight or fight response. It will help oxygenate the blood in preparation for battle. Hyperventilating is an emergency response signal and if perceived by others will offer medical assistance and emotional support. If this sort of sympathy is desired, then shallow breathing can help garner that sort of attention. Use the signal with care so as not to appear overly dramatic or emotionally unstable.

Context: a) Dating, b) General.

Verbal Translation: “I’m getting so excited I need to consume more and more oxygen in order to get the job done.” “

Variant: See Deep Breathing.

Cue In Action: a) She panted with excitement as their lips met – her lust was obvious b) He was left alone in the woods and didn’t know where he was. The more he moved, the more he panicked. He nearly hyperventilated from fear.

Meaning and/or Motivation: a) When sexually aroused, women (usually) will breath with an excited pace as if hyperventilating. This is thought to function as a way to take in more of the aroma of her partner. b) During a state of elation, panic or fear, people will often take frequent, but shallower breaths.

Cue Cluster: a) Various other sexual cues such as increased proximity, eye contact, removing clothing to be more comfortable, preening, and so forth. b) The winning sports team will often be seen with their arms extended, their heads thrown back and their mouths and eyes opened wide in a state of ecstasy.

Body Language of Sex Flush

Body Language of Sex Flush

No picCue: Sex Flush.

Synonym(s): Sex Blush.

Description: A measles-like rash appearing on the breast and chest usually in women (and sometime men) nearing orgasm.

In One Sentence: The sex flush is a nonverbal signal that says an orgasm is near.

How To Use it: Women can use reddening to appear artificially sexually aroused by applying make-up to the cheeks and even the upper chest. This is an artificial likening to sexual arousal which men will find alluring. Otherwise, the cue is not something that can be consciously controlled making it not something that is readily used as a voluntary nonverbal cue.

Context: Dating.

Verbal Translation: “I’m having an orgasm and the flow of blood is increasing to my skin.”

Variant: Blushing.

Cue In Action: Her heart was racing as she panted heavily; she arched her back forced her legs together and went into an erotic tremble. Her skin turned bright pink, glistening, and she couldn’t catch her breath.

Meaning and/or Motivation: The sex flush is found in nearly seventy-five percent of women and twenty-five percent of men and does not occur at any other time and is not a direct reaction to temperature, but tends not to occur in colder climates.

The sex flush, or vasocongestion is an increase of blood flood throughout the skin. In women, the skin turns pinkish under the breast, which spreads to the torso, face, hands and feet. In some cases, the entire body might flush. In men, the skin turns pink in the abdomen, then chest, neck, face, forehead, and occasionally the shoulders and forearms. The sex flush typically subsides quickly after orgasm but can last up to two or more hours and result in increased perspiration.

Cue Cluster: During orgasm breathing often becomes heavy, muscular contractions of the pelvic area including the vagina, uterus and anus, the feet may curl, the legs press together.

Body Language of Ear Blushing

Body Language of Ear Blushing

BodyLanguageProjectCom - Ear Blushing 1Cue: Ear Blushing

Synonym(s): Ear Flushing

Description: Reddening of the ears.

In One Sentence: Ear reddening is a sign that someone is experiencing nervousness, stress, embarrassment, excitement, or is being physically active.

How To Use it: Ear reddening is not a cue that is usefully used and happens autonomically.

Context: General.

Verbal Translation: “I’m getting worked up and blood is rushing to the periphery of my body in effort to produce a cooling effect.”

Variant: See Blanching.

Cue In Action: a) It was Stacey’s turn to present next, her heart began to race and her ears turned a bright shade of red, she was nervous. b) The marathon caused the runner to flush in the face, ears, neck and chest.

Meaning and/or Motivation: Blushing usually appears in the chest and cheeks, but it also occurs in the ears. Blushing signifies stress, excitement, embarrassment and nervousness.

Other times people are prone to blushing with relatively low stress levels as a physiological condition. Blushing can also be the result of high activity levels where blood is pumped all over the body and outer skin so it can give off heat and cool the body off.

Blushing is linked to the release of adrenaline and cortisol which courses through the body. The hormone also diverts blood flow from the digestive system and shunts it to major muscle groups giving them a burst of energy. As a side effect, our blood vessels that deliver blood to our faces dilate, meaning they relax or open, allowing more blood to reach the surface of our ears causing them to turn red.

Cue Cluster: We usually see other nervous body language with blushing such as trembling hands, head lowering, shoulder shrugging, body turned away, eye contact avoidance, shaking the head, overall freezing, and lowered voice volume.

Body Language Of Crying

Body Language Of Crying

BodyLanguageProjectCom - Crying 1Cue: Crying

Synonym(s): Damp Eyes, Teary Eyes, Weepy Eyes, Eyes Glistening.

Description: Eyes that weep due to emotional pain.

In One Sentence: Eyes that tear demonstrate high emotion including joy and suffering.

How To Use it: Use crying to show others that you are either really happy or really hurt. Eyes are an honest signal showing others that you are experiencing intense emotions. Demonstrating pain, can help you bond with other people or gain sympathy if experience emotional of physical pain. Crying has been shown to reduce the level of punishment as it creates feelings of sympathy. Thus, when an authority figure is about to dish out their sentence, crying is nearly certain to be of benefit. Women are likely to benefit most from crying and a first reaction to being wronged is this very condition. Crying is therefore quite common from women facing judge and jury.

Crying when being hit, or being scolded, or when facing authority, often improves the outcome of a situation because it elicits sympathy from the more dominant person thereby lessening punishment. Men are not advised to use crying when facing others as this is usually read as weakness and loss of emotional control. Men are usually permitted to cry only when mourning death.

Context: General

Verbal Translation: “I’m overwhelmed with so much emotion it’s welling up and pouring out of my eyes.”

Variant: Eyes can sometimes be overjoyed due to passion, and love. Likewise, anguish, distress, and bereavement produce so much extra moisture that it makes the eyes glisten.

Cue In Action: When she found out the news, she cried with joy, her baby girl was going to be married.

Meaning and/or Motivation: Damp eyes can have many nonverbal meanings. They can indicate tiredness or suppressed weeping, anxiety or sadness. Crying symbolizes an overflowing of emotions such as sadness from emotional hurt, from pain due to physical hurt, or from extreme joy. However, crying is a universal signal of sadness.

Cue Cluster: Crying appears in a cluster that highly depends on the context. When joy is the cause, crying is accompanied by relaxed and open body language. When crying is due to sadness, closed and tight language appears in cluster.
