Administration in the healthy life expectancy stretching box (50℃ temperature for 30 min) can cause profuse perspiration and an elevation of body temperature, due to the far-infrared-ray emission effects of the interior of the box containing natural rock. The present study was designed to evaluate the effects of the healthy life expectancy stretching box on chemotherapy-induced toxicities in patients receiving carboplatindoublet chemotherapy. We prepared two healthy life expectancy stretching boxes with and without the interior of box containing natural rock. 10 subjects were randomly administered with and without the interior of box containing natural rock at 3 and 4 cycles of chemotherapy. Subjects experienced the healthy life expectancy stretching box one day before, one day after, and seven days after carboplatin-doublet chemotherapy. Toxicities including general fatigue, nausea, appetite loss and general condition were assessed using a visual analog scale for a week after the chemotherapy. General fatigue and general condition were significantly improved in patients who experienced the healthy life expectancy stretching box containing natural rock, compared to those in control patients without the experience and without the interior of the box with natural rock. Our results indicate that the healthy life expectancy stretching box is useful for the maintenance of general condition after carboplatin chemotherapy in patients with malignancy.
