Getting stuck in quicksand can be a frightening experience, and while it is not as dangerous as it is often depicted in movies, it can still cause minor muscle damage and lead to more serious health complications. When a person or animal steps into quicksand, they begin to sink, and the more they struggle, the deeper they sink. This is because quicksand is a non-Newtonian fluid, meaning it behaves like a solid until it is agitated, at which point it quickly turns to liquid. This non-Newtonian property is due to the mixture of sand with water or air, which creates a soupy, liquefied solid that can be found all over the world. While it is impossible to be sucked down to the bottom of quicksand due to its density, the pressure exerted on the body can cause minor muscle damage, known as crush syndrome, and can lead to more severe health issues if the person remains trapped for an extended period.
| Characteristics | Values |
|---|---|
| Formation | Quicksand forms when wet sand is suddenly dislodged or when soil is exposed to upward-flowing water. |
| Composition | Quicksand is a non-Newtonian fluid, a mixture of sand and water, silt and water, clay and water, sediment and water, or sand and air. |
| Viscosity | Quicksand changes its viscosity in response to stress or vibration, allowing individuals to sink but making it difficult to escape. |
| Buoyancy | The torso is buoyant enough to stay afloat due to the presence of lungs, while the legs may sink due to their higher density. |
| Muscle Damage | Extended pressure on skeletal muscles, such as the legs, can lead to crush syndrome, causing compression damage to muscles and nerves and releasing compounds harmful to the kidneys. |
| Hypothermia | Individuals stuck in quicksand lose body heat up to 25 times faster than on land, increasing the risk of hypothermia. |
| Dehydration | If trapped for an extended period, individuals may experience dehydration. |
| Suffocation | Depending on the position, quicksand can impair breathing and lead to suffocation. |
| Drowning | Drowning is possible if an individual falls into quicksand headfirst or if tides or heavy rainfall occur near the quicksand. |
| Rescue | It is challenging to pull someone out of quicksand due to its strong suction. Rescuers must be careful to avoid causing further harm. |

What You'll Learn
Remaining calm can prevent sinking further into quicksand
Getting stuck in quicksand can cause minor muscle damage due to the pressure of the sand, which can also shut off blood flow and cause nerve damage. This is known as Crush Syndrome, which can lead to the release of compounds that harm the kidneys.
If you are carrying anything heavy, such as a backpack, drop it immediately to make yourself lighter. If possible, take off your shoes, as they can create suction and make it harder to pull your feet out. If only your feet are stuck, take small steps backward to reach solid ground before the quicksand fully liquefies.
If you are stuck deeper, lean and float on your back to increase your body's surface area and make it harder to sink. Wriggle your legs slowly and carefully to help them float towards the surface and introduce more water into the dense sand, loosening the quicksand's hold. Once your legs are free, use your arms to "'swim' to safety" and roll onto solid ground.
If someone is stuck in quicksand, it is important to keep them calm and slowly pull them out. Sudden movements can cause them to sink faster and deeper, making it more challenging to escape.

Removing weight can help you float
Quicksand is a non-Newtonian fluid, meaning it's solid in one state, but if anything agitates it, it quickly turns to liquid, causing you to sink. While it's not very deep—usually only a few inches or feet at most—and it's extremely unlikely that you'll drown in it, quicksand can still be incredibly dangerous. If you're trapped and there's no one around to help, you could suffer hypothermia, dehydration, or even suffocation. You might also be at risk of crush syndrome, which can lead to kidney damage.
If you find yourself stuck in quicksand, the best thing to do is to remain calm and try to reduce your weight to help you float. Here are some tips to keep in mind:
Remove any extra weight
If you're wearing a backpack or carrying something heavy, immediately take off your backpack or drop what you're carrying. The less weight you have, the slower you'll sink. If possible, take off your shoes as well, especially if they have flat, inflexible soles, as these can create suction when you try to pull them out of the quicksand.
Lean back and increase your surface area
By leaning back, you distribute your weight over a wider area, making it harder for you to sink. This is because quicksand is denser than the human body, so by increasing your surface area, you can use your body's buoyancy to your advantage and float.
Grab onto something
If there's a tree branch or vine nearby, grab hold of it. Put as much weight as you can on the object you're holding onto, as this will slow down the sinking process and help you stay afloat.
Wiggle your legs
Wiggling your legs or making slow back-and-forth movements can help liquefy the sand and free your legs. This can also allow water to enter the cavity around your trapped limb, loosening the quicksand's hold.
Breathe deeply and stay calm
Taking deep breaths helps to fill your lungs with air, making you more buoyant and helping you float. Panicking can cause you to flail around, creating a vacuum that will fill in with more densely packed sand, causing you to sink further.
Remember, quicksand is usually sensitive to pressure and vibrations, so the more you move and struggle, the deeper you'll sink. By removing extra weight, staying calm, and using the right techniques, you can increase your chances of safely escaping quicksand.

Leaning back can prevent sinking
While it is rare for people to sink all the way into quicksand, it is still incredibly dangerous. If you find yourself stuck in quicksand, leaning back can prevent you from sinking further. Quicksand is denser than the human body, so people and animals float on the surface. However, our legs are pretty dense, so they may sink. Leaning back increases your surface area, making it harder for you to sink. This is because the weight of your body is distributed over a wider area.
If you are stuck in quicksand, it is important to remain calm and not panic. Panicking can cause you to sink further, but if you relax, your body's buoyancy will cause you to float. Take deep breaths to remain calm and make yourself more buoyant. Keep as much air in your lungs as possible as it is impossible to go under if your lungs are full of air.
If you have any bags, jackets, or anything heavy on you, take them off and throw them away. The less weight you have, the slower you will sink. If you are with someone, grab their hand, or grab hold of a tree branch or vine nearby. Put as much weight as you can on the object you are holding onto. This will slow down the sinking process and help you stay afloat.
If your feet are stuck, try to take a few small steps backward onto solid ground before the quicksand takes hold. Quicksand usually takes a moment to fully liquify, so you have a short window to "unstick" yourself. If your legs are stuck, wiggle your feet to help liquefy the sand and free your legs.

If you are stuck in quicksand, it is important to remain calm and not panic. Panicking can cause you to flail around, creating a vacuum that will fill with densely packed sand, causing you to sink further. Take deep breaths to remain calm and make yourself more buoyant. Drop any heavy items you are carrying to make yourself lighter.
Now, onto the main point: wiggling your legs can help free you. Small, slow back-and-forth movements can let water into the cavity around your trapped leg, loosening the quicksand's hold. Wiggling your feet will help liquefy the sand and free your legs. Try to take small steps backward to get onto solid ground.
If you are unable to free yourself, call for help. It is important that rescuers are careful when pulling you out, as quicksand's suction is incredibly strong and could rip you in half.

Crush syndrome can lead to kidney damage
Getting stuck in quicksand can be dangerous, but it is unlikely to be fatal. While it is often portrayed in films as something that people sink into and drown, in reality, quicksand is typically not deep enough for this to happen. However, there are still several ways that getting stuck in quicksand can be life-threatening. One of the dangers of getting stuck in quicksand is crush syndrome, which can lead to kidney damage.
Crush syndrome, also known as Bywaters' syndrome or traumatic rhabdomyolysis, is a medical condition that occurs when extended pressure is applied to skeletal muscle, such as the legs. This compression damages muscles and nerves, releasing compounds that can cause kidney damage. Specifically, the compression causes the release of muscle breakdown products, including myoglobin, potassium, and phosphorus, into the bloodstream. Myoglobin is filtered by the glomeruli and reaches the tubules, where it obstructs and causes the failure of renal function. Other intracellular components such as protons, phosphate, and nucleotides are also released.
The risk of crush syndrome is why it is recommended that non-professional first-aiders in the UK do not attempt to release individuals with a crush injury who have been trapped for more than 15 minutes. If the pressure is released during first aid, fluid intake must be restricted, and an input-output chart for the patient must be maintained. Treatment for crush syndrome includes the use of a tourniquet to stall the life-threatening consequences of the injury, fluid replacement, and careful administration of intravenous sodium bicarbonate.
To avoid getting stuck in quicksand, it is important to learn to anticipate places where quicksand is likely to be encountered. Quicksand is most commonly found near coastal areas, marshes, and riverbanks. It can also form anywhere groundwater mixes with sandy soil, creating a soupy mixture. If you do find yourself stuck in quicksand, it is important to remain calm and not panic. Drop any heavy items you are carrying to reduce your weight, and try to lean back and increase your body's surface area to slow down the sinking process.
