The instinct takes place for typically no longer than the final 20–60 seconds during drowning and before sinking underwater. [3] 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 drowning compared to a person unable to do so.
The diving reflex is a set of physiological responses that occur in response to cold water immersion, particularly when the face or body is exposed to cold water. It is an evolutionary adaptation that helps mammals , including humans, manage the challenges of being submerged in cold water.
Similar to how reflexes are physically connected and thus do not require control of individual components by the central nervous system, actions can be executed through synergies with minimal executive control because they are functionally connected. Beside motor synergies, the term of sensory synergies has recently been introduced. [37]
Drowning is a type of suffocation induced by the submersion of the mouth and nose in a liquid. Submersion injury refers to both drowning and near-miss incident. Most instances of fatal drowning occur alone or in situations where others present are either unaware of the victim's situation or unable to offer assistance.
Out of 65 sharp-force suicides, only two victims still held their weapon post mortem. This low incidence rate suggests that genuine cadaveric spasm was not exhibited. [4] Gravity may play a large factor in the trapping of limbs and other objects under the body at the time of death, and the subsequent observed placement of limbs after death. [6]

The ridge in the upper part of the picture is the high pressure of the upper esophageal sphincter which only opens for a short time to let water pass.
