A Five-year Study on the Relationships between Alpha-Waves and Business Performance for a Japanese Businessman

It is qualitatively known that alpha-waves enhance business performance. This study aimed at substantiating this fact quantitatively by measuring alpha-waves every morning and evening for seven months, in order to determine (1) if the appearance of alpha-waves in the morning would enhance business performance of that day, or (2) if good business performance would increase alpha-waves in the evening. As a result, constant tendencies of (2) were observed. Then yearly, monthly and weekly differences in the appearance of alpha-waves and business performance were analyzed for a five-year period. In addition, changes in the appearance of alpha-waves due to weather, temperature and humidity were examined. It was found that the appearance of alpha-waves did not vary greatly with weather, temperature and humidity, while business performance changed significantly with the year, temperature and humidity.
