| Outline of Final Research Achievements |
We are always exposed to environmental physical and chemical stresses.To diminish the effect of such stresses on our physical function,epidermal tissue works,where containing stratum corneum water is required for keeping the function of epidermal tissue.We have reported an increase of stratum corneum water by body warming.In this study,we focused on the seasonal effect on the increase in stratum corneum water by body warming.
Result:1.The increase in skin blood flow:The effect in summer was more than that in winter.2.The increase in stratum corneum water: As the increase in blood flow is followed by the increase in stratum corneum water,the effect in summer was also more than that in winter.3.Water vaporing from skin：Water vaporing was detected in summer,but not observed in winter.These results suggest that the capacity of water content in stratum corneum is limited.Therefore,water vaporing takes place as shown in summer,when the water content increases over the threshold.
