ABSTRACT
Immersion in cold water causes a complex response. In some cases the exposure may be rapidly fatal due to cold shock. A victim who survives this period may not be able to rescue themself because of a loss of power. Divers need to be aware of hypothermia as a diving problem, but it is also a problem if they become hypothermic during the remainder of their time on the water, when they are likely to be less well protected.
