“...the cold never bothered me anyway” is a line from a Disney song that has been recorded in languages all over the world. It has won many awards and has been recognized in many countries. In the Thai version, the song is sung by Kam Wichayanee Piaklin. In this part, she sings, "...the cold doesn't cause us much trouble" which may be in contrast to the weather conditions in Thailand which don't know the word "winter" causing them to neglect to take care of their own health when the cold wind blows through

Thailand is close to the equator. It is considered a tropical monsoon zone, causing the weather to be different from other parts of the world. In Thailand, many people often say that Winter doesn't really exist and the cold has never caused much suffering to Thai people. Is that true?
One part of the song Let's it go “...the cold doesn't cause much trouble.” This may resonate with many people because most Thai people rarely experience cold weather. Except for some areas in the northern region and the northeastern region that has suffered from the cold weather But thatdoes not mean that other areas Thailand clearly has winter.As a result, many people neglect health care during the climate change period. The cold wind has returned again. It inevitably brings about disease and sickness without us being aware of it. Just because we think “The cold doesn't cause much trouble.”
