Feeling bursts of excitement and occasionally rubbing hands together can be a normal and natural response to certain situations or emotions for some individuals. People express excitement in various ways, and rubbing hands together is one of the possible gestures that can accompany such feelings.
Excitement can arise from positive events, accomplishments, upcoming plans, or other emotionally charged situations. It often manifests in physical and behavioral changes, such as increased heart rate, smiling, laughing, jumping, clapping, or, as you mentioned, rubbing hands together.
It's essential to note that what is considered normal can vary between individuals and cultures. Some people may naturally show more visible physical expressions of emotions, while others might be more reserved or internalize their feelings.
However, if this behavior becomes a compulsion or is accompanied by other distressing symptoms, such as obsessive thoughts or actions that interfere with daily life, it may be a good idea to consult with a mental health professional for further evaluation. They can determine whether the behavior is within a typical range or if it indicates an underlying condition that requires attention.
In general, as long as the behavior is not causing distress or harm to yourself or others and is a spontaneous expression of excitement, it is likely to be considered within the realm of normal human behavior.
