How Smell, Taste & Pheromone-Like Chemicals Control You | Episode 25 Huberman Lab

    • Health & Fitness

This episode I explain how we sense chemicals by way of smell, taste and pheromones. How things smell and taste and chemicals in the tears, breath, and on the skin of others have a profound effect on how we feel, what we do and our hormones. I explain the 3 types of responses to smell, the 5 types of tastes, the possible existence of sixth taste sense and how the act of sniffing can make us learn and focus better. I explain how smell and taste reflect brain health and can be used to assess and even promote brain regeneration. I discuss how eating specific categories of foods makes us crave more of those foods. Both basic science and protocols are described including how to make sour things taste sweet and how to develop a heightened sense of smell and taste.
