Discover how our sense of smell can transport us back to meaningful memories, shape our emotions, and influence the brain systems involved in memory and mood. Summary: Smell is one of our most powerful and underappreciated senses, with a unique ability to evoke memories and emotions. On this episode of The Science of Happiness, we look at the science behind smell’s close relationship with memory, emotion, and our environment and we explore how paying attention to the scents around us can bring us back into our bodies and help us feel more connected to the present moment.  How To Do This Practice:  Step outside: Spend 10–15 minutes somewhere you can notice natural scents, such as a park, garden, or neighborhood. Breathe through your nose: Take a few slow breaths in through your nose and notice the scents carried in the air. Pay attention: Notice what catches your attention; don’t be concerned with trying to identify smells Follow your curiosity: Move toward different plants, trees, flowers, or other natural elements and see how their scents change. Notice what comes up: Pay attention to any memories, emotions, or sense of place that a particular scent evokes. Stay present: Take a moment to appreciate the experience and notice how you feel after giving your sense of smell your full attention. Scroll down for a transcription of this episode.

单集文稿 ...

  • I went down to the Berkeley Marina.

  • Then a breeze came from the bay and I got my first whiff of seawater, bay water,

  • that salty, salty water smell, which is a very like core, core, core smell.

  • Like that is in the atoms of my soul.

  • It's like a savory, salty, slightly funky smell.

  • It's not super strong, but it's just enough for me to pick up on my nose.

  • And what that brings up for me is tide pooling as a kid.

  • And you kind of saw what in Southern California is called the marine layer, this thick layer of fog.

  • We would be driving into the marine layer in the mornings.

  • That was just such like a fundamental memory.

  • It really is, I would say, transporting is a good word.

  • I really am at the meeting of land and sea when I'm breathing that.

  • And I'm very aware of, like, the ocean environment

  • and the ocean life and the sea life and being at the edge of the world in a way.

  • Like many people, I had a complicated childhood.

  • To me, one uncomplicated thing about that is my relationship to the ocean and my relationship to the water.

  • So I always love being transported.

  • Welcome to the Science of Happiness.

  • I'm Dacher Kildner.

  • Think about the last time a smell stopped you in your tracks.
