Physical contact is an important element of communication in Brazil and visitors should not be alarmed or intimidated by this. As in most Latin cultures, a firm and enthusiastic handshake is customary among men, often followed by a slap on the shoulder or squeeze of the upper arm. When women meet, they will normally kiss each other on the cheek (one kiss on the left cheek) and/or give a light hug. Men are also expected to greet women with a kiss, although Brazilians may forgo this with foreigners so as not to make the visitor feel uncomfortable. Physical contact is not confined solely to greetings, but is a normal and constant element of interaction, albeit in slightly different forms. For example, if a Brazilian has something important to tell someone or wishes to abruptly change the subject, he/she will frequently reach out and lightly touch the interlocutor’s hand. A Brazilian may also touch or take someone’s hand in the middle of a conversation when laughing or expressing shock. Brazilians also use their hands a lot when talking, so the visitor can expect constant gesticulation.

This is just a sample of what you'll find in the complete Brazil guide.
