A game commonly misunderstood as a means of exciting euphoria. This can be dangerous, and if you're alone, you should'nt attempt it, coz it acn cause death, being misunderstood as a case of suicide. It is played by two method:
1. Strangulation (or increasing pressure on carotid artery and thus influencing baroceptors (mechanoreceptors or sensors) leading to vasodilation(widening of vessels) leading to insufficient blood supply to brain. Can lead to head trauma resulting in death if practised alone.)
2. Hypocapnia or low level of carbon dioxide in blood due to hyperventilation (a form of deep and rapid breathing.) This can causing alkalosis which causes vasoconstriction(or narrowing of vessels) leading to brain, resulting in neuromuscular irritibility and dizziness, misunderstood as euphoria(or exagerrated elation.) This leads to cerebral hypoxia(or less amount of oxygen) leading to unconsciousness.
This can be attempted as a fun game(in local schools) but the lack of oxygen, if not treated properly, can lead to death if left as such.
