What does nod mean

Shaking his head

Is the shaking of the head the sign for "No" and the nodding of the head the signal for "Yes" all over the world?

An infant turns its head sideways away from the mother's breast when it is full. It is believed that this gesture was imitated and amplified and that this gave rise to the negative shaking of the head.

By increasing the rotation of the head around the central axis of the body and repeating the movement, the signal became clearer. It is considered a sign of rejection in almost all cultures in the world.

However, one should look carefully, because there is a gesture that is very similar to the no, but means the opposite: In Bulgaria and in some areas of India, rocking the head means an unequivocal "yes". In contrast to shaking the head, the face remains facing forward when weighing and the movement is usually carried out a little more slowly.

In these countries, as well as in Greece, the "no" is expressed by throwing the head up. Sometimes the eyes are also closed and the nose wrinkled. The eyes and nose are moved away and protected by the rejected stimulus - just like when you shake your head in the negative.

Unfortunately, however, this movement again closely resembles the sign for "yes" that is common in other cultures and therefore confuses many visitors to these countries. Because the nod of the head is a signal of approval almost everywhere in the world.

Presumably the nodding lowering of the head arose as a gesture of submission or humility. You bend to the imagination of the other person. The repetition of the movement reinforced the signal and today the vertical up and down movement of the head is a clear sign of approval. Culturally different are the sharpness of the movement and the strength of the inclination of the head.
