Background of Research

Rohto has conducted research on the functionality of Restful Green and confirmed its effectiveness in reducing mental fatigue and anxiety. This time, the study focused on "digital fatigue" caused by digital operations such as smartphones, PCs, and games, which are believed to be the cause of sleep deprivation and poor sleep quality among the working generation in recent years.

About Restful Green


It is a scent module blended based on Berea Lab's proprietary know-how, and is a unique combination of ingredients extracted from natural plants that have been proven to have anti-fatigue and stress-reducing effects on humans in past research. The company will continue to conduct further research on the effectiveness of this scent module.

Test Method

From June to August 2020, two professional e-sports players (one male and one female) practiced the 3D fighting game "Tekken 7" for 3 hours a day in a controlled environment for 14 days.

The players wore a wearable heart rate sensor myBeat (manufactured by Union Tool Corporation) for 24 hours a day, and in addition to monitoring autonomic nervous system activity and body movement throughout the day, psychological and subjective assessments of sleep were conducted before and after game practice to determine whether the space where the game practice took place had a green aroma component (Restful Green ) on alternating days with and without the green aroma component (Restful Green), and compared the results.


Study Results

The study showed that the use of Restful Green during game practice had an effect on the activation of neural activity during practice, recovery from fatigue after practice, and improved sleep quality, compared to the use of no scent.


Test Subjects' Voices

Test Subject 1


Mr. MASA ( @tekken_masa)

I had some sense that the scent of green calmed me down during practice, but I was surprised to find that it resulted in an increase in my winning percentage and made a difference in the quality and duration of my sleep. The results of this study really changed my awareness of fragrances.
I would like to practice while smelling green fragrance in the space where I usually spend a lot of time (such as my room) and when I sleep, especially on days when I want to sleep well, such as the day before a competition.


Test Subject 2


Mimi ( @mimi00618)
Affiliation: DIGITAL HEARTS Gaming Main Title: Tekken 7

I used to like aroma and use it in my bedroom, but I thought it had nothing to do with improving my game performance. I have a hard time changing my habit of going to bed late at night because the most exciting time of the day is at night when online games are played.
I really appreciated the fact that I could improve the quality of my sleep simply by using the green scent during practice. I hope the scent can be used to help me relax right before a game so that I can improve the quality of my sleep even during a short sleep period.
