Design outcomes

Primary

MeasureTime frame
1. The area under the curve (AUC) of the right palmar skin surface temperature from immediately to 30 minutes after cold water load at examination 12 weeks after consumption (12w)

Secondary

MeasureTime frame
1. The measured values of the right palmar skin surface temperature at each measurement point, and the changes from measurements before and immediately after cold water load at 12w 2. The recovery rate of the right palmar skin surface temperature at each measurement point (except before and immediately after cold water load) at 12w 3. The AUC of the left palmar skin surface blood flow from immediately to 30 minutes after cold water load, the measured values at each measurement point, and changes from measurements before and immediately after cold water load at 12w 4. The subjective cold-related symptoms measured by visual analogue scale (VAS) before and 30 minutes after cold water load at 12w
