The researchers Yun-Fang Tsai and Hsiu-Hsin Tsai belong to the school of nursing in Taiwan; Thomas Wong is from the school of nursing in Hong Kong, while Yeong-Yuh Juang works in the Department of Psychiatry in Taiwan.

For this purpose, the old patients that were hospitalized because of depression in a subtropical climate area are selected. The experiment was conducted in such a way that patients had to sit in front of a light box where they faced 5000 lux early in the morning.
