Cold emotions are those that are experienced with a low level of arousal. They may well be more cognitive in experience then emotional. In a cold state we may be calm and in control of ourselves. We may also bored, flat and lethargic.
First, it's important to realize that many cold and distant people act that way because of the way they were brought up. For example, they may have been pushed away by their parents when they were younger, and the hurt from that experience causes them to protect themselves emotionally.
Warm emotions give energy and satisfaction and help you develop companionship with the people you serve. Cold emotions cost energy, are frustrating and hinder the development of companionship.
Some people naturally tend to feel colder than others without any discernible cause. However, cold intolerance can also indicate an underlying medical condition, such as hypothyroidism, anemia, or peripheral artery disease.
Unfeeling, unemotional, affectionless; unsmiling—straight-faced (or stone-faced) Cold-hearted, as in "cold fish" or (even worse) an "iceberg" or "ice queen" Lacking empathy and compassion.
Focus on your own feelings
Both Neblett and Gatling agree that if you address someone's emotional unavailability, express how it's affecting you and lead with "I" statements. It's also important to have clear examples of why you think they're emotionally unavailable so that they don't feel ambushed, Neblett emphasizes.
Someone who's coldhearted is detached and unfeeling. It would be coldhearted to stand there, not caring, when you see a little kid fall and hurt herself. Most people are sympathetic and warm, but those who don't have much feeling for others are coldhearted.
They don't get emotional about things and may even be isolated for long time. Cold-hearted people are often unable to feel the same warm feelings that you and I have, such as affection for a friend or enjoyment at the birth of a child, because they lack warmth.
There are many reasons a person blows hot and cold. It could be that they are not ready for a committed relationship; they don't know what they want; they are not sure what to do about their intense feelings for you; or they are emotionally unstable or unavailable.
Post Traumatic stress disorder
People who witness a violent crime, traumatic events, and/or war-like conditions tend to develop post traumatic stress disorder.. People suffering from post traumatic stress disorder grow emotionally detached overtime and can lead to a change in the overall perception of one's emotions.
Friendship.
Emotionally unavailable people find banter, or their shared history with someone, easier to cope with so they'll often keep a friendship at a slight distance. Sadly, it means their friends will never fully know them.
Alexithymia is when a person has difficulty experiencing, identifying, and expressing emotions.
One of the key signs that you're emotionally detached is that you aren't open or forthright with others regarding your emotions. You tend to keep things very private, hidden, and under wraps. Even if you're feeling sad or hurt, you never open up about this to others or let your true emotions show.
Detaching can give you the emotional space you need to take care of yourself. Sometimes, caring too much about another person's life and problems can have a negative impact on your own emotional and physical health. You may start to have headaches, lose sleep, or be more irritable.
Recognize that when a woman shuts down emotionally (or a man!) it is because she is trying to protect herself from getting hurt. Maybe she had a bad experience with a parent or former partner, and she is afraid to be yelled at or abused in some way. Shutting down emotionally is often a form of self-preservation.
You Probably Think They Don't Even Care
When someone has emotionally shut down, they certainly look like they don't care. Their facial expression is usually neutral, with little to no expression of emotion, and their voice tone becomes monotonous. Answers to questions are short.
They avoid commitment
Fear of commitment and fear of getting too close are two common signs of emotional unavailability in men and women. Emotionally unavailable partners might prefer having casual relationships with multiple people or may end relationships if things are getting “too serious.”
One of the common traits of an emotionally distant woman is avoiding all sorts of conversations. When you try, she might appear irritated or might ghost you. She will often make excuses to avoid getting together, connecting, or catching up. Another common trait is, you find her secretive.
Introverts are good at tempering their emotions.
Introverts experience their emotions intensely, although most people wouldn't realize it by looking at them. While their minds might be running nonstop, they often don't show those emotions on the outside. Unfortunately, this sometimes makes introverts look cold.
