Unlocking the Secrets of Your Sense of Smell: Part 6


Our sense of smell is directly linked to the area of our brains that controls our memories. The slightest hint of an odour can transport us thousands of miles to some of our earliest memories—even to those we were not aware that we had.

Our sense of smell is directly linked to the area of our brains that controls our memories.  The slightest hint of an odour can transport us thousands of miles to some of our earliest memories—even to those we were not aware that we had.

With our sense of smell, every odor when broken down to its smallest component is a chemical formula. Chemicals formulas are molecules in specific configurations. When we smell, a chemical formula rises in the nose and lands on thousands of smell receptors which identifies the molecules and forwards the information to the brain.

That our sense of smell is most closely related to our memory is no surprise given its location.

Olfactory receptors are located next to the limbic system which, according to anthropologists, is the most primitive part of the human brain and where our emotions reside.  It is the site that controls or modifies our emotional and sexual responses, our hunger and thirst responses, and our anxiety and fear responses.

 It also controls our artistic abilities, our perception of space as well as regulating our body temperature, and our ability to think.  It receives and stores information from all of our senses.  Essentially, it’s our master control.

When we inhale a scent, the sensation of its odour is first relayed to our cerebral cortex, where cognitive recognition occurs.  However, before we are able to recognize the scent, the deepest part of our brain becomes stimulated.  Thus, by the time we are able to recognize the pine scent of a Christmas tree, its scent has already activated our limbic system and we are transported back to our childhood memory of decorating Christmas trees from our past.

In this same way, when we smell the gingerbread scent from a votive candle, we instantly think of our grandmother’s kitchen, or making cookies with her when we were children.  It isn’t surprising, then, that studies conducted by Dr. Rachel Hertz suggest that our memories which are triggered by our sense of smell are more emotional than our memories triggered by our other senses.

In one study subjects were given visual (an object), verbal (the name of an object) or olfactory (the scent of an object) stimuli and asked to write down their responses to them.

While responses to visual and verbal stimuli tended to be longer, those to olfactory stimuli tended to be memory-based.

Some of the fragrances that help to increase memory include sweet basil, peppermint, rosemary and thyme.

The Sense of Smell and Emotional Response


When oils are inhaled, micro-molecules of essential oils travel through the nasal passages to the limbic system of the brain which is the seat of memory and emotion.
The breathing in of essential oils is thought to trigger memories and emotions within the limbic system, which in turn stimulates a response within the entire system.
With the memory comes instant recall of the associated emotion - pleasure, happiness, laughter, affection or perhaps sadness, pain, grief.
For this reason, it is important to always heed the emotional responses to the aroma of the essential oils you intend to use. If the scent is in any way repellent, then it is wise to adjust your choice of oils for your blend. The subconscious, emotional responses are telling you something of vital importance and you would be wise to listen. Otherwise, you severely curtail the degree of benefit given.
Smell takes a direct, physical route to the brain because they employ nerve cells as transmitters and receivers. Odours travel directly through the olfactory system in the nose and the front part of the head into the limbic area of the brain which processes the smell.

What is that Smell?


Indoor air quality is an important component to keep employees healthy and productive.  Symptoms of deficient air quality can present in many different ways such as fatigue, headaches, difficulty focusing, and soreness of the nose, lungs, throat, and eyes.  These symptoms can be early warning signs for problems that lead to longer lasting health issues.  One indicator of poor air quality or that something un-sanitary is growing in your office building is a foul smell. 

Smell is a strong indicator that something somewhere has gone awry.  Foul odors are also one of the most difficult things to diagnose in a large office environment.  Many times a maintenance manager or a building maintenance company will call an industrial hygiene firm to come out and perform some air tests.  A good industrial hygienist will come out with several pieces of equipment and begin sampling the air.  Typically they will need to take at least one sample in the infected area, one sample outside the infected area, and one sample outdoors.

These different samples allow them to compare the infected area sample with what is in the air “normally” inside and outside.  Sometimes they take more than one sample in the infected area.  In cases where the mystery smell more resembles a musty odor, then the hygienist might pull up a piece of carpet to see if there is any mold growing underneath.  If they see anything that is suspicious looking on the surface then they should take a “surface sample.”  This sample will give the lab something to analyze besides just spores in the air.

Many factors play a role when it comes to air quality.   Bacteria do produce odors and when there is adequate buildup of certain bacteria then there will be smell.  Identifying why those particular bacteria have become prevalent in any situation is the job for an industrial hygienist.  People often try to clean odors with bleach.  While bleach will kill the surface bacteria, it does not penetrate deep and kill the root cause of the bacteria
Indoor air quality is a catalyst for airborne pathogens and should be taken seriously within every office environmentIf you start smelling mystery smells contact an environmental, health and safety firm to perform tests in your office building.  To find a firm near you click here
