In recent years, the symptoms associated with the menstrual cycle including pre-menstrual syndrome (PMS) leading to poor body condition and their effects on daily life and work have been recognized as a health problem distinctive to wom-en. There are various coping methods to improve PMS symptoms, and stress management is also important for this improvement.

This study examined the difference in the relaxation effects of planetarium watching after work with regarding to working women during their menstrual cycle. Twenty women in their 20s and up to their 40s were the participants, and they were classified into three groups: pre-menstrual, men-strual, and another period; verification was done using two planetarium pro-grams. Results suggested that premenstrual women showed a rapid increase in body surface temperature while watching the program, and this was not limited to the program structure. In addition, from the analysis results of POMS2, in which there were significant decreases in Confusion-Bewilderment, Tension-Anxiety, and TMD scores after planetarium watching. Accordingly, the planetarium could bring relaxation effects for women in premenstrual period.
