Cold water shower Vs. Warm water shower, which one is better for health?

Taking a shower is a-must routine for Thai people because the weather in Thailand is hot, very hot, and extremely hot! Some people love to take a shower with cold water while some people like to take a shower with warm water no matter how hot the weather is. Do you know the benefits of cold water showering and warm water showering? and what is the difference between these 2 types of taking a shower? ACU PAY would love to tell you.
