A social chemosignaling function for human handshaking

The study explores the concept of chemo-communication through handshaking, suggesting that the act of handshaking can transfer chemosignaling relevant molecules. The researchers conducted experiments to ascertain the influence of odours on this behaviour, and found that it is indeed odour-driven. The study also addresses potential variables such as handedness and the use of cosmetics. However, the authors acknowledge that further research is needed to fully understand the phenomenon.
