Influence of the Experimental Mouth Breathing on the Work Efficiency

Originally, nasal breathing is a physiological breathing style of human being, but when the normal nasal breathing is impaired by nasal obstruction such as rhinitis, it is said to reduce the QOL such as headache, fatigue, sleep disorders, drowsiness of daytime, a decrease of attention. In this study, an experimental mouth breathing is created by obstructing the nose of a person whose usually breathing style is nasal breathing, and we investigated how mouth breathing is whether the extent involved in the decline of attentsadokugo ion or concentration to weigh mouth breathing with nasal breathing the work efficiency of the challenges.We was performed the Uchida Krepelin test in adults to 34 people, and the Stloop color word test of 27 adults whose usual breathing style is determined to nasal breathing. The experimental mouth breathing when you have a nasal obstruction was used as the experimental group, and nose breathing that does nothing was used as a control group, so two groups were compared. Evaluation items are the number of incorrect answers and reaction time of Stloop color word test, the average amount of work total average amount of work, the first half of the average amount of work, the second half of the average amount of work, the average amount of work 5 rows of late start, the specific row the number of incorrect answers of the Uchida Kraepelin test.In conclusion, 1. In the Stloop Color Word test, it compared to the control group, those in the experimental group were observed trend of increasing the number of incorrect answers, the extension of the reaction time. 2. In Uchida Kraepelin test, the total average amount of work, the first half of the average amount of work, the second half of the average amount of work, the average amount of work of 5 rows of late start, those in the experimental group was significantly reduced compared to the control group. Accordingly, we found that the work efficiency falls by persons of nasal breathing becomes the mouth breathing temporarily. From this study, the experimental mouth breathing has been suggested possibility of effect a decrease in attention or concentration, and leading to a reduction of working efficiency. but this is a case where it becomes the mouth breathing temporarily present results. Therefore, it is about whether applies to resident basis mouth breathing person, we must continue research in the future.
