Dry drowning isn’t real: What parents should know about water safety | Expert opinion
Why "dry drowning" is a myth and what steps to take to prevent water-related injuries and deaths.
No parent should lose sleep over a condition that doesn’t exist.
Yet every summer, viral headlines resurface the myth of “dry drowning,” the misleading belief that a child can suddenly die days after a normal swim from water hidden in their lungs.
As a pediatric emergency room doctor, I know these rumors are not harmless. Terms like “dry drowning” create anxiety about letting children enjoy the water. They also generate false expectations about the need for long-term vigilance after swimming. Instead, we must help families recognize the real signs of respiratory distress after a water incident.
Water play and swimming are fun ways for kids to stay cool and active in the summer, but water safety should always come first. Drowning is the #1 leading cause of death in children 1 to 4 years of age in the U.S., and a major risk for older children as well. Inaccurate information can distract from proper prevention, recognition, and treatment, so we must understand the facts to stay safe around water.
What is drowning?
Drowning occurs when water gets in the way of normal breathing. This can happen quickly (in under 30 seconds) and silently; most kids do not scream and splash like in the movies. Drowning is not always fatal; symptoms can present or persist after a child gets out of the water but they occur shortly after the event, not days later.
Symptoms of drowning include coughing, trouble breathing, chest pain, vomiting, pale or blue-appearing skin, or being unusually sleepy, irritable, or less interested in playing. These symptoms occur as a result of the body’s natural response to drowning; the body tries to clear water from the windpipe and lungs through protective reflexes like coughing before critical organs like the heart and brain suffer from a lack of oxygen. Children who develop concerning symptoms should be promptly evaluated by a medical professional.
Drowning can occur in either salt water or fresh water, or any kind of liquid. And it doesn’t just happen in oceans and pools; young children have drowned in bathtubs, buckets, and even toilets. All it takes is a few inches of water.
Why is “dry drowning” a myth?
“Dry drowning” — the idea that a child can look well after a water incident and then deteriorate days later without warning due to water in their lungs — doesn’t exist. Drowning by definition requires breathing issues caused by water. Since oxygen is necessary for life, the body does not wait days before telling you that something is awry.
So how long should parents monitor their child? Multiple analyses of drowning events have shown that symptoms occur immediately or shortly after water exposure — usually within eight hours. If water reaches the lungs, it can trigger inflammation that may take several hours to become apparent. A child who is acting like their normal self is unlikely to develop symptoms from drowning beyond this initial period.
If we recognize drowning and intervene quickly, we can help a child before breathing issues can lead to organ failure and death. The effects of non-fatal drowning range from no injury at all to severe complications, including brain damage or permanent disability. Swift action, however, can help limit the long-term consequences.
If a child gets sick days after playing in the water, they haven’t drowned, but they still need to be seen by a healthcare professional to be evaluated for other serious conditions.
How to prevent drowning
I once cared for a young child who wandered out of her house without her parents noticing, only to be found unconscious in her neighbor’s unfenced pool. Kids are naturally curious and want to explore the world; it is up to us to keep them safe. Using multiple layers of protection can greatly reduce the risk of drowning:
Swim lessons: Swimming is a life skill; the American Academy of Pediatrics recommends that all children start swim lessons after their first birthday. Similar to putting on your own oxygen mask before helping others in an airplane emergency, supervising adults should know how to swim so they can help others. Check out classes in Philadelphia and the surrounding area for you and your children.
Properly fitted life jackets: Small children and weak swimmers should wear U.S. Coast Guard-approved life jackets whenever they are near water, including pools and waterparks. Everyone should wear a life jacket when boating or participating in water-based activities in open water, such as lakes, rivers, and oceans. Inflatable aids like “floaties” are not safe substitutes as they can deflate and do not prevent drowning. Refer to the U.S. Coast Guard brochure for guidance on choosing a properly fitted life jacket.
Four-sided pool fencing with a self-latching gate: Fencing that surrounds pools decreases the risk of drowning by a whopping 83% compared to three-sided fencing or no fencing. Barriers should be a minimum of four feet high, and avoid horizontal bars, chain links, or nearby patio furniture that children could easily climb.
Close supervision: Even with a lifeguard present, adults should closely supervise infants, toddlers, and noncompetent swimmers at all times when near water, staying within arm’s reach and avoiding distractions like phones, socializing, or alcohol. This applies to bathtubs, buckets, and toilets as well. Caregivers should always clearly hand off supervision responsibilities.
Emergency preparedness: Parents, caregivers, and pool owners should be CPR trained in case of an emergency. Older children and adolescents can learn too. For the patient I cared for, CPR saved her life. A year later, she is thriving with no residual deficits.
With the right precautions, we can help kids enjoy the water safely all summer long. Talk to your pediatrician or visit CHOP Pediatric Health Chat whenever you have questions about kids’ health.
