艾尔切克医生说，最好用热牛奶，因为相比冷牛奶能够更快穿透皮肤，但他警告说，不要在牛奶浴池里待太久。
'It's a double-edged sword because on one hand you want to stay in there long enough to absorb the nutrients,' he said. 'On the other hand, you will become dehydrated if you stay in too long and the water will literally roll out your skin. I would say anything beyond 15 minutes would be harmful.'
他说：“洗牛奶浴是一把双刃剑：一方面你想待得够久，，让皮肤吸收养分，但另一方面，如果你待得太久，水分会从皮肤流失，导致脱水。我的建议是泡牛奶浴不要超过15分钟。”
