Investigation of the effect of repeated use of steam heat sheets before menstruation on alleviating menstrual-associated symptoms
Others
To determine the optimal duration of application of steam heat sheets to the lower abdomen for alleviating menstrual-associated symptoms.
Exploratory
Not applicable
Menstrual-associated symptoms (pain) according to the duration of steam heat sheet application (7 days, 1 day, no application).
Differences in menstrual-associated symptoms (non-pain symptoms), and in expressions used to describe pain and perceived effectiveness (subjective descriptors of effect), according to the duration of steam heat sheet application (7 days, 1 day, no application).

In menstrual cycle 1, apply a steam heat sheet to the lower abdomen for 8 hours per day for 7 consecutive days (daily for 7 days, starting 7 days before the expected Day 2 of menstruation). Cycle 2: washout (no application). In menstrual cycle 3, apply a steam heat sheet to the lower abdomen for 8 hours on a single day (Day 2 of menstruation).

Female
1. Females aged 20-49 years.
2. Regular menstrual cycles (cycle length 25-38 days, with month-to-month variability generally within <=3 days) and able to report the dates/durations of the three most recent menstrual periods.
3. Self-reported mild menstrual-associated symptoms (symptoms that do not interfere with daily activities or work).
1. Currently receiving outpatient care, taking medication for, or with a history of gynecological disorders (e.g., dysmenorrhea, uterine fibroids, adenomyosis, endometriosis, cervical intraepithelial neoplasia, cervical cancer, etc.).
2. Regular use of analgesics (including over-the-counter medications) during the premenstrual or menstrual phase.
3. Presence of hepatic, renal, cardiac, respiratory, endocrine, metabolic (e.g., hypertension), neurological disorders, disorders of consciousness, diabetes, or other medical conditions that would preclude participation in the study.
4. Received medication therapy or surgery for a serious illness or injury within one month prior to study initiation and judged by the principal investigator or study staff to be unsuitable for participation.
5. Receiving hormone replacement therapy (HRT) or taking medications that may affect hormonal status (including oral contraceptives).
6. Pregnant, breastfeeding, or planning to become pregnant during the study period.
7. History of eczema or urticaria induced by steam-heat stimulation.
8. Impaired thermal sensation or hypersensitivity to temperature.
9. Any other condition judged by the principal investigator or study staff to render the participant unsuitable for the study.
10. Participation in another clinical trial of drugs or food products within the past month, or planned participation in such a trial during this study.
