IS the risk of dying worth it?? Find another way to raise money instead of putting people at risk with unknown health risks. In the study, published in the Journal of Physiology, Prof Tipton and Prof Mike Shattock of Kings College London explain how rapid submersion in cold water, combined with holding ones breath, automatically activates two powerful responses in the body which may interact and cause conflict for the heart. The bodys cold shock response speeds up the heart rate and causes hyperventilation which can conflict with the diving response, which does the opposite and which acts to conserve oxygen. This can lead to autonomic conflict, causing the heart to go into abnormal rhythms and, on occasions, causing sudden death. The prevalence of heart problems on immersion in water tends to be underestimated because electrical disturbances to the heart are undetectable post-mortem. The incapacitation caused by cardiac arrest, such as gasping for breath and breathing in water, means that death is often ascribed to drowning, but we believe a significant number of these cases could have a basis in autonomic conflict. Immersion-related deaths are the second most common cause of accidental death in the UK with one child a week lost from this cause, according to a spokeswoman for the University of Portsmouth.
