SUDDEN UNEXPECTED NOCTURNAL DEATH SYNDROME

Since 1977 more than a hundred Southeast Asian immigrants in the United States have died from the mysterious disorder known as sudden unexpected nocturnal death syndrome (SUNDS). SUNDS had an unusually high incidence among recently relocated Laotian Hmong refugees. All but one of the victims were men, the median age was thirty-three, all were apparently healthy, and all died during their sleep. Despite numerous studies of SUNDS, which have taken into account such varied factors as toxicology, heart disease, sleep apnea and other sleep disorders, genetics, metabolism, and nutrition, medical scientists have not been able to determine its exact cause. Medical opinion appears to favor an impairment of the electrical pathways and specialized muscle fibers that contract the heart. It is widely held, however, that some type of intense stressor is likely an additional risk factor.

The medical folklorist Shelley Adler postulates that a supernormal nocturnal experience that is part of Hmong traditional beliefs can trigger the fatal syndrome. The experience is referred to as a "night-mare," not in the modern sense of a bad dream, but rather in its original denotation as the nocturnal visit of an evil being that threatens to press the very life out of its terrified victim. Hmong refugees in the United States experience a culture-specific manifestation of the universal nightmare phenomenon. The Hmong Nightmare (known as dab tsog) causes cataclysmic psychological stress, which can trigger sudden death. Although the Dab Tsog attack in Laos is related to the worldwide nightmare tradition, the peculiar stresses of Hmong refugee experience transformed its outcome. The power of traditional belief in the nightmare—in the context of the trauma of war, migration, rapid acculturation, and inability to practice traditional healing and ritual—causes cataclysmic psychological stress to male Hmong refugees that can result in SUNDS.

Can SUND be related to sleep paralysis? A lot of the folklores that I've heard about the "Dab Tsog" it seems to have similiar symptoms as SP. People who claimed to have experienced it said it was like they were awake but could not move their bodies no matter how much they tell themselves too. I accidently stumbled upon this site.. and it got me interested. My mother told me that one of her brother died suddenly in his sleep after they moved to the USA after the Vietnam War. Doctors could not figure out why. He was a healthy man in his 30's, whom was a Dentist back in Laos.

talking about SUNDS. Here in the Philippines, we call it "OROM". many of us here experienced that and we found ways to wake up. SUNDS is like, you are very conscious of what is going on around you. you can here your relatives passing by, youre eyes are closed but you can move your eyeballs and the more you strugle, the lesser the chance of walking up again. when we experience this sunds, there are there parts that we know that we can move. our hands, thumbs of our feet and our mouth. we either move our toe or grasp our hands if its not enough, we bite our tounge. usually people here experience sunds when they are very tired and sleep. a study has been made about rice. it may be another factor because asians eat rice and many say that sunds were only experienced by asian people. hope this little info can help.
