Culture-bound syndromes are conditions in which physical or psychological distress is strongly shaped by cultural beliefs, social norms, and local understandings of illness, often without a single clear biomedical equivalent. Filipino examples include Bangungot, associated with terrifying nightmares, sleep paralysis, and sudden nocturnal death; Pasma, linked to weakness, numbness, and body pain believed to result from imbalance or overwork; Usog, commonly associated with fever, bloating, or discomfort after encounters with strangers; and Kabuhi, a Visayan folk illness involving epigastric pain, acidity, nausea, burping, and weakness often linked to stress, hunger, or fatigue.
