Every person must have felt nervous. There are some bad habits that made people to cover her nervousness. These habits seem hard to stop, but actually can be stopped if there is intention. We’re nervous or anxious, the brain systems of the brain will tell the hypothalamus to release the hormone corticotrophin releasing factor (CRF), then these hormones can trigger another hormone that is adrenocortocotrophin (ACTH).
This hormone can enter the bloodstream to the kidneys to stimulate the gland hormone cortisol to release adrenaline. At that time most people will feel excited, cold sweat, trembling even to want to pee. If cortisol attack became part of the brain memory center (hippocampus) it can be nervous when someone becomes forgotten with everything that was in his brain. “Any bad habits is something that is appreciated by these people, because it can make people relax, relaxation or a little more quiet. Because if the habit is not respected, then that person may not want to continue to do so,” says psychologist Carol Goldberg of New York City, as quoted by LiveScience, Thursday (21/1/2010).
Here are some bad habits that people do to mask her nervousness, namely:
1. Biting.
This is the most common habits that affect a third of children, adolescents and 44 percent of 19-29 percent of adults. This habit usually starts from the children or because it follows the style of others.
2. Thumb.
This habit is usually done by a baby who does have any urge to suck. These habits may continue until the children aged 2-4 years or maybe even until adolescence.
3. Overeating.
People who eat too much have a variety of reasons, including to reduce anxiety, frustration or loneliness. The reason people turn to food for the consumption of certain foods can increase the sense of making people happy or relaxed.
4. Smoking.
