Assessment
Primary outcomes
Tympanic temperature (tympanic temperature sensor)
Observed for 2 minutes after taste stimulus
Observed for 50 minutes after heat stimulus
Key secondary outcomes
# Whole body sweating distribution (Minor method: per adult, a mixture of 15 ml of iodine solution, 90 ml of anhydrous alcohol, and 10 ml of castor oil is applied to the skin with a brush, and after drying, starch powder is spread thinly and evenly. The iodo-starch reaction causes the sweating area to turn a dark purple color.)
# Local sweating rate (ventilation capsule method)
# Skin blood flow (local laser Doppler skin blood flow meter, 2D laser blood flow imager for skin blood flow distribution)
# Whole body skin temperature distribution (infrared thermography)
# Axillary temperature (skin temperature sensor)
# Heart rate variability (MemCalc/TarawaTM)
Observed for 2 minutes after taste stimulus
Observed for 50 minutes after heat stimulus

Interventions/Control_1
Experiment Day 1: After 50 minutes of whole-body heat stimulation (room temperature 40 degrees Celsius, relative humidity 50%), 150 mg of red pepper powder is applied to the tongue and included in the oral cavity. Two minutes later, the oral cavity is rinsed with fresh water and observed until each measured factor such as tympanic temperature returns to the same level as before spicy stimulation.
Experiment Day 2: Under neutral room temperature (25 degrees Celsius, 50% relative humidity), 150 mg of each of the various taste stimulants is applied to the tongue and included in the oral cavity. Two minutes later, the oral cavity is rinsed with fresh water and observed until each of the measured factors, including tympanic temperature, returns to pre-taste stimulation levels. The subject is then allowed to rest for 2 minutes. The next taste stimulus is then administered. The entire process is expected to take approximately 1 hour.
