Recovery Wear "Miranes" Observes Changes in Condition-Related Indicators During Wear
PiquePop Co., Ltd. announced test results showing that wearing its recovery wear "Miranes" leads to statistical changes in REM sleep percentage, subjective sleep evaluation, and fatigue index. The unique "W Far-infrared Design®" aims to support high-quality rest through improved blood circulation.

PiquePop Co., Ltd. (Headquarters: Fukuoka City, Fukuoka Prefecture; Representative Director and President: Ryosuke Yamanaka), which develops the recovery wear "Miranes," conducted a study to verify the relationship between the product, which incorporates its proprietary "W Far-infrared Design®" technology, and biological responses and sleep indicators during wear. The results of this study observed statistical changes in REM sleep percentage, subjective sleep evaluation, and fatigue index when wearing this product, whose primary action is to promote blood circulation.
■ Background
In modern society, the decline in the quality of rest due to busy daily lives is a concern for many people. Miranes views high-quality rest as a "miracle" and aims to support physical recovery and comfort through a scientific approach.
This study was conducted to investigate how Miranes' functions, which support blood circulation promotion and fatigue recovery, affect physiological changes during sleep and the subjective feeling of sleep.
■ Study Outline
The study verified the effects on sleep structure and autonomic nervous system activity when wearing recovery wear with the proprietary "W Far-infrared Design®," as well as the changes in subjective evaluation due to continuous daily wear.
Study Participants: 16 healthy men and women aged 30s to 60s who agreed to participate through public recruitment and were deemed eligible by a physician. (15 participants analyzed)
Study Method: Measurements during sleep were conducted under conditions of wearing this product, which incorporates the "W Far-infrared Design®." In addition, the product was worn continuously for one week in daily life to investigate changes.
Evaluation Items:
・Sleep Structure: REM sleep percentage and the composition ratio of each sleep stage were calculated by polysomnography (PSG) examination.
・Autonomic Nervous System Activity: Autonomic nervous system balance and activity status were evaluated using heart rate variability (HRV) analysis.
・Fatigue Index: Physical fatigue was measured using objective fatigue index measurement.
・Subjective Sleep Evaluation: Sleep satisfaction and fatigue were quantified using a 10-point self-assessment method (questionnaire).
■ Study Results
Changes in Sleep Structure (REM sleep percentage): A statistically significant difference in REM sleep percentage was observed in objective sleep evaluation.
Changes in Autonomic Nervous System Activity (HRV index): A statistically significant difference in autonomic nervous system activity indicators in the early stage of sleep onset was recorded in heart rate variability (HRV) analysis.
Changes in Subjective Sleep Evaluation and Fatigue Index (1 week of continuous wear): Statistically significant differences were observed in all four subjective evaluation items and the objective fatigue index after wearing compared to before wearing. Furthermore, a tendency for changes to become more pronounced with continuous use was confirmed, with larger differences observed after one week.
*These results are reference data for this product, whose primary action is to promote blood circulation, and do not indicate an improvement or enhancement of sleep quality. Also, these study results were obtained under specific test environments and do not guarantee effects in all usage environments.
*Results may vary among individuals.
■ Mechanism of "W Far-infrared Design®"
Miranes recovery wear adopts a unique design combining "special material with excellent thermal conductivity" and "mineral prints that radiate far-infrared rays." This mechanism is expected to provide four effects*: "promote blood circulation," "alleviate muscle stiffness," "support fatigue recovery," and "soothe muscle fatigue," supporting a comfortable daily life.
*The feeling of effects may vary among individuals.
The results of this study suggest that Miranes, whose primary action is to promote blood circulation, shows statistical changes in REM sleep percentage, subjective evaluation, and fatigue index. Utilizing this knowledge regarding product characteristics, we will continue to aim for a garment that supports daily condition and will support physical condition maintenance and comfort through a scientific approach. We hope Miranes will be a part of everyone's rich lifestyle, looking towards the future.
