While distress and panic may sometimes take place beforehand,<unk>  itself is quick and often silent. A person close to the point of<unk>  is unable to keep their mouth above water long enough to breathe properly and is unable to shout. Lacking air, their body cannot perform the voluntary efforts involved in waving or seeking attention. Involuntary actions operated by the autonomic nervous system involve lateral flapping or paddling with the arms to press them down into the water in the effort to raise the mouth long enough to breathe, and tilting the head back. As an<unk>  reaction, this is not consciously mediated nor under conscious control. The lack of leg movement, upright position, inability to talk or keep the mouth consistently above water, and (upon attempting to reach the victim) the absence of expected rescue-directed actions, are evidence of the condition. Timing The instinct takes place for typically no longer than the final 20–60 seconds during<unk>  and before sinking underwater. In comparison, a person who can still shout and keep their mouth constantly above water may be in distress, but is not in immediate danger of<unk>  compared to a person unable to do so.
