In this Huberman Lab Essentials episode, I explore how your sense of smell (olfaction), taste, and chemical sensing influence memory, alertness, focus, and even communication between people.

I explain how these senses help us detect chemicals in the environment and respond to a variety of environmental cues. I discuss the connection between the olfactory system and cognitive performance, and I provide practical tools to enhance learning, sensory function, and brain health. Additionally, I examine how chemical signals exchanged between people subtly influence emotions, biology, and social bonds.

Huberman Lab Essentials episodes are approximately 30 minutes long and focus on key science and protocol takeaways from past Huberman Lab episodes. Essentials are released every Thursday, while full-length episodes continue to air every Monday.
