Have you ever wondered why adults warn, "Don't sit on the pillow"? Or else you'll get a boil on your buttocks? Let's explore the ancient belief that carries hidden lessons about respect and hygiene, along with surprising medical reasons.
"Don't sit on the pillow or you'll get a boil on your buttocks." This familiar phrase is a warning many have heard from elders since childhood, becoming a deeply rooted taboo in Thai society. From the perspective of belief and astrology, some see it as a superstition or a taboo for good luck. However, ancient wisdom cleverly embeds lessons consistent with science and hygiene.
Looking back at the cultural and social context of old Thailand, this prohibition is based on two main factors:
In Thai culture, the "head" is considered high and the dwelling of sacred spirits or life essence, while the "feet" or "buttocks" are low. Using a pillow meant for the head as a seat is inappropriate because it places something low on something high, which elders view as disrespectful and unlucky.
Ancient people often used fear to teach children. Explaining reasons directly might not stop the behavior, so they warned, "If you sit on the pillow, you'll get a boil on your buttocks" or "Be careful of boils." Since boils are painful inflammations, this scared children into not doing it again.
Analyzing this belief with modern hygiene and medical knowledge reveals that the warning "has some truth in terms of hygiene." Although sitting on a pillow does not directly cause boils on the buttocks, this behavior clearly harms skin health.
A pillow used for the head contacts the face and respiratory passages throughout the night. If the same pillow is sat upon, dirt, bacteria, dust, or sweat residues from clothes and the buttocks accumulate in the fabric. When used again for sleeping, bacteria and dirt come into direct contact with facial skin.
This can lead to "inflamed acne," allergic rashes, or bacterial infections on the face. In severe infections, inflammation may cause painful swelling resembling boils.
Nowadays, with many types of pillows available, sitting on pillows is not illegal or life-threatening. However, in terms of use, pillows should be clearly separated by type. Sleeping pillows should be used for the head only to maintain facial skin and respiratory hygiene. For sitting, cushions specifically designed to support body weight should be used.
Understanding the ancient belief "Don't sit on the pillow" is not merely about disrespect or superstition but about learning to honor culture while properly maintaining personal hygiene.
