Fear of the water is one of those primal things. It’s hardwired into our DNA for a reason. Most people wonder, usually at 3 AM when the brain won't shut off, does it hurt to drown? We’ve all seen the movies where someone flails around for five minutes before sinking gracefully into the abyss. It looks cinematic. It looks poetic. But the reality is messy, fast, and surprisingly quiet.
Honestly, the answer depends on which stage you’re talking about. Drowning isn't a singular moment. It’s a physiological process. It involves a sequence of events that triggers every survival instinct you possess. It starts with panic. It ends with a lack of oxygen to the brain. In between, there is a very specific type of pain that most survivors describe as a "burning" sensation.
The Instinctive Drowning Response
Forget the shouting. Forget the waving.
When someone is actually drowning, they rarely make a sound. Francesco Pia, a Ph.D. who coined the term "Instinctive Drowning Response," spent years studying actual footage of people in distress. He found that the body takes over. You can’t wave for help because your arms instinctively reach out laterally to press down on the water’s surface. This is your body trying to leverage itself up just high enough to get a mouthfull of air.
It’s exhausting.
The struggle usually lasts only 20 to 60 seconds before the person sinks. During this time, the "hurt" isn't necessarily physical pain in the way a cut or a break is. It’s the agony of air hunger. It’s the sheer, blinding terror of your brain realizing it is being deprived of its most basic fuel. You’re hyperventilating, but you’re gulping water instead of oxygen.

So, let's get into the mechanics of the "hurt."
When you can no longer keep your airway above the surface, you hold your breath. This is the voluntary phase. It lasts until the carbon dioxide levels in your blood spike. This is what scientists call the "breakpoint." Your body doesn't actually care how much oxygen you have; it reacts to how much $CO_2$ is building up. That build-up creates an overwhelming, agonizing urge to breathe.
Then comes the water.
When you finally inhale, water hits the larynx. For many, this triggers a laryngospasm. Basically, your vocal cords seize up to protect the lungs. It’s a defense mechanism that backfires. You can't breathe water in, but you can't breathe air in either. This causes a vacuum in the chest.
Survivors of near-drowning, like those interviewed in various medical journals and documentaries, often describe a "tearing" or "burning" feeling in the chest. It’s sharp. It’s cold. Imagine pouring acid into your chest cavity—that’s how some have described the sensation of salt water or even chlorinated pool water entering the delicate tissues of the lungs.

Chemistry matters here. It sounds nerdy, but the type of water you're in changes how you die.

If you drown in fresh water, the water is "hypotonic" compared to your blood. This means the water crosses the lung membranes and enters your bloodstream almost instantly. It wrecks your red blood cells. It causes a massive electrolyte imbalance that can lead to cardiac arrest in as little as two to three minutes.
Salt water is different. It’s "hypertonic." It actually draws fluid out of your blood and into your lungs. You essentially drown in your own fluids while the salt water sits there. This process takes a bit longer—usually eight to ten minutes.
Which one hurts more? Most experts suggest salt water is more "active" in its discomfort because the pulmonary edema (fluid buildup) is more intense. Fresh water is a faster "shut down" of the electrical systems in the heart.
The "Peaceful" Myth
You might have heard people say drowning is peaceful once you give up.
There is a kernel of truth there, but it’s morbid. Once the brain is sufficiently deprived of oxygen—a state called hypoxia—you start to lose consciousness. The "fight" ends. This is where the endorphins kick in. As the brain begins to shut down, some survivors report feelings of calm or even euphoria.
But make no mistake: the road to that calm is paved with a violent struggle for life. The "peace" is simply the brain’s way of turning out the lights.
Secondary Drowning: The Silent Threat
Sometimes you get out of the water and think you’re fine. You aren't.
There is something called "dry drowning" or "secondary drowning," though many medical professionals prefer the term non-fatal drowning. Even a small amount of water inhaled into the lungs can cause inflammation or a "washout" of the surfactant that keeps your lungs open. Hours later, you can find yourself unable to breathe.
If someone has a "close call," you need to watch for:

- Persistent coughing.
- Extreme fatigue (brain hypoxia).
- Changes in behavior or irritability.
- Chest pain.
What to Do If You See Someone Struggling
Knowing that it hurts to drown should be a motivator for safety, not just a morbid curiosity. If you see someone who looks like they are "climbing a ladder" in the water, they are likely in the Instinctive Drowning Response.
- Throw, Don't Go: Unless you are a trained lifeguard, jumping in can result in two victims. A drowning person will instinctively climb you like a tree, pushing you under to keep themselves up. Throw a buoy, a rope, or even a cooler.
- Call for Help Immediately: Professional medical intervention is required even if they get out and look okay.
- CPR is Key: If they are unconscious, the priority is getting oxygen to the brain. Start rescue breaths and chest compressions immediately.
Beyond the Physical
We focus a lot on the nerves and the lungs. But the psychological trauma is massive. Survivors often deal with lifelong PTSD. The memory of that "burning" sensation and the realization that the world is disappearing behind a veil of blue stays with them.
The biological reality is that drowning is a high-stress, high-pain event until the very last moments of consciousness. The body fights with everything it has. It’s not a "falling asleep" feeling. It is a metabolic riot.
Actionable Safety Steps
To prevent ever having to experience what drowning feels like, follow these non-negotiables:
- Life Jackets are Non-Negotiable: On a boat, wear it. Even if you're a "strong swimmer." A sudden cramp or hitting your head makes your swimming skills irrelevant.
- Learn to Float: Survival swimming (floating on your back) uses way less energy than treading water. If you're tired, flip over.
- The 10/20 Rule: Lifeguards use this. Scan your zone every 10 seconds and be able to reach a victim within 20 seconds. If you're watching kids at a pool, put the phone away. Drowning is silent.
- Medical Follow-up: If you or a child inhales water and has a coughing fit, go to the ER. Don't "wait and see" if they breathe better in the morning.
Drowning is a preventable tragedy. Understanding the physical reality—the burning, the $CO_2$ buildup, and the rapid loss of control—is the best way to respect the water. It’s a powerful element. It doesn't care how well you can swim if you don't respect the limits of your own biology.
