Some people feel shy. 
Shy people may fear what others think. They might worry about being teased. This fear can make them want to hide.
Shyness can come from many things. It can come from how you are born. It can also come from what happens to you.
Sometimes, shyness changes as you grow up. Many children feel less shy when they are older.
Being shy is just one way to be. Everyone is different!
Shyness is a feeling of being awkward or uncomfortable. 
Shyness comes from many things. It can come from your genes. Genes are parts of your body passed down from parents. Some studies say shyness is partly genetic. It can also come from your environment. This means the way you are raised. For example, being teased by others can lead to shyness.
Shyness is not the same as introversion. An introvert chooses to avoid crowds. They just do not find them rewarding. But shy people feel distress in social spots. They feel fear or worry.
Shyness can change as you grow. Many children feel less shy by age 13. Some people stay shy for their whole lives. It can even affect how well students do in class. Shyness can make it hard to talk or make eye contact.
Shyness is a personality trait that many people feel. It is a sense of awkwardness or lack of comfort around others. 
Scientists believe shyness can happen in a few different ways. One way is through genetics, which are traits passed down from parents. Another way is through your environment, or how you are raised. For example, emotional abuse like ridicule can cause shyness. There is also a biological side to how shyness works in the body. Some research suggests that having too much cortisol can be a factor. Cortisol is a substance that can suppress the immune system. This might make a person more likely to get sick.
Researchers have studied the history of shyness for many years. Papers about the biological roots of shyness date back to 1988. In 1996, a study looked at how anxiety-related traits are passed down. That study found that anxiety traits might be 40% to 60% heritable. This means they are passed down through genes. Since then, more progress has been made in finding specific genes. One gene is called 5-HTTLPR, which is linked to shyness in grade school children. Scientists also use mouse models to study genes like the one for GABA synthesis. This helps them learn more about how behavior works in humans.
There are many interesting facts about how shyness develops. Some studies show a link between birth weight and being shy. Children born at low birth weights may be more cautious. Another study looked at how much daylight there is during pregnancy. In the United States and New Zealand, scientists found a connection. Children exposed to shorter days during mid-pregnancy were 1.52 times more likely to be shy. This suggests that one out of five cases of extreme shyness might be linked to day length. Even mercury poisoning can cause symptoms like extreme shyness or lack of confidence.
Shyness can change as a person grows up. Many children find they are less shy by the age of 13. Some people may carry shyness as a lifelong trait. Shyness can also affect how well a student does in the classroom. It can make it hard to make eye contact or speak easily. Some people might even act in strange ways to try to be interesting. In some cultures, people show shyness by hiding behind someone else. 
Shyness is a complex personality trait characterized by feelings of apprehension, awkwardness, or a lack of comfort around other people. It is most common in new situations or when interacting with unfamiliar individuals. While people often confuse it with other behaviors, shyness is specifically defined by a fear of how others will judge a person's behavior. This fear involves worrying about negative reactions like being mocked, criticized, or rejected. To avoid these feelings, a shy person may choose to retreat from social settings.
It is important to distinguish shyness from related concepts like introversion and social anxiety disorder. Introversion is a personal preference where a person avoids social contact because they do not find it rewarding. In contrast, shyness is driven by distress and fear. Social anxiety disorder is a narrower, more severe psychological condition. It involves intense worry about being evaluated by others, which can lead to panic. While shyness is a personality trait, social anxiety is often a more intense condition related to depression.
The origins of shyness are multifaceted, involving genetics, environment, and biology. Scientists believe shyness is at least partially genetic, though researchers still debate the exact causes. Environmental factors also play a role, such as experiencing emotional abuse or ridicule during childhood. Biologically, shyness may be linked to an excess of cortisol. Cortisol is a hormone that, in high quantities, can suppress the immune system. This suppression may make an individual more susceptible to various illnesses and diseases.
Research into the genetics of shyness is a specialized field that has existed since at least 1988. One area of study involves the serotonin transporter promoter region polymorphism, or 5-HTTLPR. The long form of this gene has shown a modest correlation with shyness in grade school children. Scientists also study the DRD4 gene, which is linked to both aggression and novelty-seeking traits. In mouse models, researchers have looked at the glutamic acid decarboxylase gene. This gene helps create an enzyme used in GABA synthesis, which is related to behavioral inhibition.
Historical studies have provided specific figures regarding the heritability of these traits. A 1996 study on anxiety-related traits noted that individual variations are 40% to 60% heritable. While specific genes were not identified then, researchers predicted that 10 to 15 genes might be involved. Thalia Eley, a professor at King's College London, suggests a different balance. She argues that only about 30% of shyness is genetically inherited. The remaining 70% may emerge as a response to a person's environment.
Other surprising factors can influence the development of shyness before a child is even born. For example, research has found a link between prenatal day length and shyness. In a study of children in the United States and New Zealand, scientists looked at day length during mid-gestation. They found that children exposed to shorter days were 1.52 times more likely to be classified as shy. This suggests that about one in five cases of extreme childhood shyness may be associated with gestation during months of limited daylight. Additionally, studies show that infants born at low birth weights may be more cautious or risk-aversive.
Shyness can change as a person matures, though it sometimes remains a lifelong trait. Many children find that their shyness fades by adolescence, often around the age of 13. Longitudinal data shows that the extreme personality types seen in infancy often evolve into more predictable patterns. However, people with shy personalities tend to internalize their problems. This means they dwell on concerns internally rather than expressing them. This tendency can sometimes lead to broader issues like depression or anxiety. 
In social and academic settings, shyness can have significant impacts. There is a documented negative relationship between shyness and classroom performance. Shy individuals may struggle with social behaviors like maintaining eye contact or assuming a relaxed posture. They might even exhibit unusual behavior to try to create interest. In some cultures, shyness is expressed by covering the mouth while laughing or hiding behind others.
