Confirmed stress reduction effect when working on a computer with menard and nail colors

 Nippon Menard Cosmetics verified the psychological state and the effect on the living body of the use of nail color, and confirmed that it has "the effect of making the feelings positive" and "the effect of reducing fatigue and stress in the typing work of the personal computer". ..

Nail color is a popular item for a wide range of ages because it has a wide variety of colors and you can easily enjoy your favorite colors and decorations, but the effect of nail color on your psychological state has not been studied much.

In Corona, which has continued since 2020, opportunities to refresh are decreasing due to various restrictions such as refraining from going out and working from home, and the company thinks that nail colors that can be easily enjoyed by oneself may help reduce stress, and verify the effect. 

In the study, eight women were asked to choose one of the 16 nail colors, "a nail color of their favorite color" and "a nail color of a color they have never used before", and nails. Psychological evaluation was performed before and after the use of color. As a result, it was confirmed that there are "positive changes in feelings" such as "feeling up" and "exciting" regardless of which color of nail color is used, and the same is true for colors that have never been used before. Was done.

In addition, in order to verify the effect of nail color on the typing work of a personal computer, 10 women were asked to select a "nail color of their favorite color" from 10 nail colors, and the measurer applied it to the subject. After that, I had them do a certain typing work using a personal computer.

Before and after the work, psychological evaluation was performed using the multifaceted emotional state scale (shortened version), and the cerebral blood flow response during the work was verified using the fNIRS device that measures the cerebral blood flow in the prefrontal cortex. As a result, it was confirmed that when nail color was used, "fatigue" for work was reduced and the amount of change in cerebral blood flow was small.

It is known that cerebral blood flow increases when receiving psychological stress, so it was thought that nail color has the effect of suppressing psychological stress on work. From this, it is expected that nail color will improve work efficiency by reducing fatigue and psychological stress caused by working on a personal computer.

Based on these research results, the company proposes to enjoy nail color as a refreshing method that can be easily implemented for depression and mental stress at home work.
