Thanks to Eric Russell for this information that is saving lives even as you read:
Drowning is the number two cause of accidental death in children, age 15 and under (just behind vehicle accidents) – of the approximately 750 children who will drown next year, about 375 of them will do so within 25 yards of a parent or other adult. In ten percent of those drownings, the adult will actually watch them do it, having no idea it is happening.
The Instinctive Drowning Response – what people do to avoid actual or perceived suffocation in the water. And it does not look like what you'd expect. There is very little splashing, no waving, and no yelling or calls for help
1.Except in rare circumstances, drowning victims are physiologically unable to call for help. The respiratory system was designed for breathing. Breathing must be fulfilled, before speech occurs.
2.Victims' mouths sink below and reappear above the surface of the water. The mouths of victims are not above the surface of the water long enough for them to exhale, inhale, and call out for help. When the victims' mouths are above the surface, they exhale and inhale quickly as their mouths start to sink below the surface of the water.
3.Drowning victims cannot wave for help. Nature instinctively forces them to extend their arms laterally and press down on the water’s surface. Pressing down on the surface of the water, permits drowning people to leverage their bodies so they can lift their mouths out of the water to breathe.
4.Throughout the Instinctive Drowning Response, drowning people cannot control their arm movements. Victims who are struggling on the surface of the water cannot perform voluntary movements such as waving for help, moving toward a rescuer, or reaching for rescue equipment.
5.From beginning to end of the Instinctive Drowning Response people’s bodies remain upright in the water, with no evidence of a supporting kick. These drowning people can only struggle on the surface of the water from 20 to 60 seconds before submersion occurs.
Keep an eye on your kids in the water, make them swim between the flags, if you suspect a problem yell for help and point, get the lifeguard's attention asap.
