The Evidence on Drowning Prevention, Without the Hype

Key takeaways

• Ages 1 to 4: drowning is a leading cause of death
• Pool fencing: a four-sided fence at least 4 feet high that separates the pool from the house and yard
• Most useful single change: Assign a "water watcher" who watches swimmers without distraction.
• Commonest mistake: Leaving a child alone in or near a bathtub, even for a moment.
• See a doctor if any of the signs under "When to speak to a doctor" below apply to you.

In depth

Drowning is the process of having breathing blocked by being submerged in water. It rarely looks the way it does in movies. A person who is drowning usually cannot shout for help or wave, because all their energy goes into trying to keep their mouth above water. Their body is often upright, head tilted back, mouth at the waterline, with arms pressing down on the surface. A young child may simply slip under silently within seconds. That is why constant, close supervision matters so much.

For young children, most drownings happen in home swimming pools and bathtubs, often during a brief lapse in supervision or when a child gets into the pool area unexpectedly. Older children, teens and adults are more likely to drown in natural water such as lakes, rivers and the ocean, where currents, cold water, alcohol and overestimating swimming ability play bigger roles. Different ages therefore need different layers of protection.

No single measure prevents every drowning, which is why experts talk about layers of protection. These include barriers that keep children away from water, close and focused supervision, swimming skills, life jackets and knowing CPR. If one layer fails, such as a gate left open, the others can still protect. Even good swimmers need several layers, because conditions in open water can change quickly and exhaustion or cold can overwhelm anyone.

Signs and symptoms

• A swimmer whose head is low in the water with the mouth at water level
• Head tilted back with mouth open, or eyes glassy and unable to focus
• Body upright in the water with no effective kicking
• Trying to roll onto the back or appearing to climb an invisible ladder
• A child who suddenly goes quiet in or near water
• After a near-drowning: coughing, trouble breathing, unusual sleepiness or confusion

Causes and risk factors

• Lapses in supervision, even for a few moments
• Lack of barriers such as four-sided pool fencing
• Weak or no swimming skills
• Not wearing a life jacket in boats or open water
• Alcohol use while swimming or boating
• Seizure disorders, heart conditions and autism, which raise risk
• Rip currents, cold water and changing conditions in natural water

How it is checked

Anyone pulled from the water who needed rescue breathing or CPR, or who has symptoms afterward, should be checked by a doctor. Water in the lungs can cause breathing problems that develop over the next several hours. Doctors listen to the lungs, check oxygen levels and may do a chest X-ray. Most people who are alert and breathing normally a few hours after the event do well.

For prevention, your child's doctor can talk with you at well-child visits about water safety, swim readiness and supervision, especially as your child becomes mobile. Swim instructors can assess a child's skills, and pool and spa safety can be checked using guidance from the Consumer Product Safety Commission's Pool Safely campaign.

Treatment and support options

Barriers around water

A four-sided fence that separates the pool from the house and yard, with a self-closing, self-latching gate, is one of the most effective protections for young children. Door alarms, pool covers and pool alarms add further layers. Keep toys out of the pool when not in use, so children are not tempted to reach for them.

Supervision that works

Choose a water watcher for every gathering near water, and rotate the role every 15 minutes or so to keep attention sharp. The water watcher should not use a phone, read or drink alcohol. For young children and weak swimmers, an adult should be within arm's reach, practicing touch supervision.

Swimming lessons

Formal swimming lessons can reduce the risk of drowning. The American Academy of Pediatrics supports lessons for many children starting around age 1, based on the child's readiness. Lessons should also teach water competency skills, such as getting back to the edge or floating. Lessons never replace supervision.

Life jackets and CPR

Children and weak swimmers should wear a properly fitted US Coast Guard-approved life jacket in open water and on boats. Adults should wear them on boats too. Learning CPR prepares you to act immediately if someone is pulled from the water, which can make a big difference while waiting for emergency help.

Prevention

• Never leave a baby or young child alone in the bath, even with a bath seat
• Keep bathroom doors closed and toilet lids down when toddlers are around
• Swim at beaches with lifeguards and follow posted warnings
• Learn to recognize rip currents and how to escape them by swimming parallel to shore
• Check that pool and spa drains have safety covers to prevent entrapment

Day to day

Families with pools or that spend time near water can build safety into everyday routines. Teach children the rule that they always ask permission before going near water. Keep a phone near the pool for emergencies only, and post CPR instructions. After swimming, lock gates and put away toys. When visiting friends or vacation rentals, check for unfenced pools, hot tubs and ponds.

As children get older, water safety shifts to good judgment. Teach them not to swim alone, to enter unknown water feet first, to stay out of water during storms and to avoid alcohol around water. Teens often overestimate their abilities, so continue talking about risks and setting clear expectations for boating, swimming at lakes and rivers and parties near water.

For specific groups

Toddlers

Children ages 1 to 4 are naturally curious and can slip into water quickly and silently. Pools, bathtubs, buckets and even pet water bowls are dangers. Barriers and constant, close supervision are the main protections.

Children with autism

Children with autism may be drawn to water and may wander, which raises their drowning risk. Swimming lessons, door alarms, secure fencing and a plan for wandering are especially important. Ask your child's doctor about local resources.

People with seizure disorders

A seizure in water can quickly lead to drowning. Showering rather than bathing, swimming only with a trained supervisor nearby and wearing a life jacket in open water reduce risk. Discuss water activities with your doctor.

Adults and teens in open water

Alcohol, overestimating swimming skills and not wearing life jackets are major factors in adult drownings. Stay sober around water, swim near lifeguards and always wear a life jacket when boating.

Questions to ask your doctor

• When is my child ready to start swimming lessons?
• Should my child have a check after a near-drowning incident?
• What symptoms after swimming mean we should go to the emergency room?
• How does my child's seizure disorder or autism affect water safety?
• Where can I learn infant and child CPR?
• What water safety steps should we take when visiting homes with pools?

More questions, answered

What is dry drowning or secondary drowning?

These terms are not used by doctors anymore. After someone inhales water, breathing problems can develop over the next several hours. Watch for coughing, trouble breathing, chest pain, unusual tiredness or confusion, and seek medical care if these appear.

Can I rely on water wings or pool noodles?

No. Air-filled toys and foam noodles are not safety devices and can slip off or deflate. Only US Coast Guard-approved life jackets are designed to keep a person afloat, and even they do not replace supervision.

How quickly can a child drown?

Drowning can happen in seconds and is often silent. A child can slip under the water while a parent answers the phone or turns to get a towel. That is why constant, focused supervision is essential near any water.

What should I do if caught in a rip current?

Stay calm and do not swim directly against the current. Swim parallel to the shore until you are out of the current, then swim back in at an angle. If you cannot, float or tread water and wave or call for help.

Are inflatable kiddie pools dangerous?

Yes. Toddlers can drown in just a few inches of water. Supervise children closely when kiddie pools are in use, and empty them and turn them over immediately afterward.

Do swimming lessons make my child drown-proof?

No. Lessons reduce risk and teach important skills, but even skilled swimmers can drown. Supervision, barriers and life jackets are still needed. Children may also forget skills between seasons.
