In the present study we examined an effect of application of Eye-Steam-Sheet in comparison with a sham eye mask. The Eye-Steam-Sheet produces heat and steam of about 40°C, when applied on the skin. After the sheet applied on the bilateral eyes of healthy subjects for 10min, the following parameters were measured: Palmar sweating measured by the finite-difference ventilation capsule method; palmar skin blood flow measured using a laser-doppler flowmeter; shoulder tissue hemoglobin measured by near infrared-spectroscopy; pupillary light reflex measured by the closed loop method. After application of the Eye-Steam-Sheet, we found that the palmar sweating decreased, the palmar skin blood flow increased, the shoulder tissue hemoglobin level increased, the miosis rate after light stimulation increased, and sensitivity of the baro receptor reflex elevated. These results suggest that application of Eye-Steam-Sheet on the bilateral eyes of healthy subjects produces parasympathetic predominance and improves peripheral hemodynamics.
