Effect of Blue Colour (453 nm Visible Range Radiation) on Anxiety in College Students

Abstract

The Biological effect of blue color therapy on self-reported anxiety in college students was determined. Female students (n = 150) of age 18 -24 from a Government college (w) Gulberg in Lahore, Pakistan were randomized into two groups (n = 75 each), Group A (chromotherapy) and Group B (control). For the treatment of anxiety, two methods of chromo therapy used were Hy-drochromotherapy (Blue chromotized water) and through watching colors (Blue chart). After 2, 4 and 6 weeks, the number of students experiencing im-provement in their anxiety from Group A were 60, 9 and 0 respectively. In Group B, students that recovered from anxiety were 17, 12 and 7 after 2, 4 and 6 weeks respectively. Relation between therapy and improvement in anxiety was examined using χ 2 statistic. Relation between these variables was signifi-cant, (1, n = 150) = 11.24, p < 0.01. After this study, 453 nm (blue color) was proved to be an effective intervention for anxiety in students. It confers a greater improvement in anxiety than does no treatment (control). This is cost effective yet an effective way of treatment with no apparent side effects.
