The handshake has been threatened several times throughout history. It was even made illegal in Prescott Arizona due to the Spanish Flu — and yet we keep returning to it. In this episode, Ella Al-Shamahi delves into a possible biological explanation for why we handshake. Studies have shown that we bring our hands close to our face after a handshake, and then subconsciously take a sniff (inhalation through the nostrils doubles). The human body emits over 2000 volatile compounds that change depending on our mood, e.g. if we’re feeling scared, nervous or happy. So, do we handshake to literally sniff out the other person? Ella speaks to neuroscientist Dr Eva Mishor from Weizmann Institute of Science to hear about her fascinating studies involving hidden cameras, life-size mannequins, sweaty smells and why handshakes can help us make better decisions. Great British Bake Off star Michael Chakraverty recounts a particularly important handshake during bread week.
