Why is it said that the Thai taboo against touching the head is related to Buddhism, and what exactly is the connection?

Because Thais wear Buddha statues around their necks, and a hand higher than these statues would mean disrespect for them, and Buddhism regards the head as very important, so their heads are not to be touched casually.

Thailanders are all believers in Buddhism, and Buddhist people see the head as a particularly sacred place, so naturally you can't touch it. Thailand also pays special attention to the size of the age and generation of the relationship, especially than their own smaller people can not touch their head, and they and different generations of people greeted in a different way.

In Thailand, a large portion of Thais are followers of Buddhism, and these followers will hang Buddha cards and Buddha statues on their neck parts. If someone else's hand touches their head so that it will be higher than the Buddha statue, this is a big disrespectful behavior for the Buddha, and it is the same thing to cross their head to pass something. But in the daily life of these people, being touched on the head by a more familiar friend, they don't care too much about it, and when you go to a Thai barbershop to get a haircut, the barber will also say sorry to you before giving you a haircut.

Touching the head of this behavior is not only taboo in Thailand, in fact, in many places are more taboo, touching the head means that all kinds of their own luck will be pressed, and more common is to say that touching the head of the growth of the high. So don't just go and touch other people's heads, it will cause resentment.

In Thailand, we must show some respect for the Buddha, even if you do not believe in the Buddha, you must treat the monks. This is because Thailand is originally a Buddhist country, is very respect for Buddhism, see Thai monks, must be polite to them to greet. Some women are even more careful not to touch these monks, because it is not easy to become a monk, and if they are accidentally touched by a woman while chanting, then the monk will have to start all over again! When there is something to be done make sure to have a man do it for them or at a distance.
