The Relaxing Effects of Scents

Maintaining Focus

Scents can be effective in situations where concentration is required. In a study of scent stimulation and its effects, participants were asked to perform a series of simplistic tasks. As a result, participants exposed to scents showed a tendency of time reduction on subsequent task engagements. Repetition of monotonous tasks usually reduce concentration in participants, but the scent was believed to help restore this concentration.

In the same experiment, results also showed that scents helped with drowsiness during tasks. From these results, some believe that scented car fresheners are useful for long-distance drives where drowsiness is easily induced due to the unchanging landscape. Smelling a scent helps us recover from fatigue and prevents us from falling asleep.

Scents Can Improve Our Quality of Life

In addition, scents have been shown to improve mental health. As an example, let’s look at a study of Japanese university students. In this study, students who often used the Student Counseling Room were asked to smell their favorite scent every morning for a week. Researchers investigated the subsequent changes in their quality of life and mental health.

Prior to the study, these students who used the counseling room had the tendency of poor quality sleep, less physical activity, and more anxiety than those who did not use the counseling room. In addition, their mental health and life quality tended to score lower. However, through this experiment, these characteristics continued to improve until there was no quantifiable difference between them and the students who did not typically use the counseling room. It’s amazing how much change occurs when we simply smell a scent that we favor.

Once a Day is All You Need

What’s interesting about the study mentioned above is not just the effect of the scent itself. The key point here is that they were only asked to smell their favorite scent once a day in the morning for a week, yet it produced more than one benefit.

We could use an aroma diffuser or light an aroma candle at home to fill the room with your favorite scent, but this can be unexpectedly tedious, and we might forget some days. What we can do is transfer our favorite aroma into a portable spray bottle for an easy and effortless alternative to carry around.

Different Scents for Different Occasions

Citrus for Stress Reduction

Citrus scents, such as lemon and grapefruit can be refreshing. They also help reduce stress and improve mood. In one experiment, grapefruit scents were presented to subjects who felt stressed after performing a simple task. Researchers measured the participants’ stress levels based on the State-Trait Anxiety Inventory (STAI), and found that their anxiety decreased more than before they had performed the task (Figure 1 below). It is likely that grapefruit had an effect on the reduction of anxiety. Similarly, it also had an effect of increased relaxation.

If you are someone who gets nervous before a presentation or meeting, smelling citrus-based fragrances may help you feel a little more relaxed.

Lavender for Improved Focus

Lavender is recommended when we struggle to keep our focus. In a study that utilized lavender scents, it was shown to improve work efficiency and reduce mistakes. Lavender scent activates the parasympathetic nervous system, thus improving concentration.

In addition, lavender fragrance is proven effective even when the scent is very faint. While lavendar could help improve our concentration, keep in mind that wearing too much perfume can cause discomfort to those around us who are sensitive to smell . A little goes a long way!
