How Smell, Taste & Pheromone-Like Chemicals Control You

YouTube | Apple Podcasts | Spotify

In this episode, Dr. Huberman explains how we sense chemicals through smell, taste and pheromones. How things smell and taste and chemicals in the tears, breath, and the skin of others have a profound effect on how we feel, what we do and our hormones. He explains the three types of responses to smell, the five types of tastes, the possible existence of the sixth taste sense and how the act of sniffing can make us learn and focus better. He explains how smell and taste reflect brain health and can assess and even promote brain regeneration. Dr. Huberman discusses how eating specific categories of foods makes us crave more of those foods. Both basic science and protocols are described, including making sour things taste sweet and developing a heightened sense of smell and taste.
