Globally, around 420,000 people die each year from falls - whether it's from a tall building or a slip in the shower. While these accidents don't always end in fatalities, the human body can recover from extreme trauma. Scientists share tips on how to position your body to minimize damage from a fall. This list explores what happens physiologically when you fall from a great height and one surprising theory on how to reduce the impact's severity and survive the unexpected.

Cells and blood vessels rupture. The brain stops getting blood needed to work.

Falling itself does not end a person. But sudden stopping alters your weight upon impact. Falling from a great height without a parachute means your body weighs about 7,500 times its normal weight when it hits the ground.You weigh 7,500 times.Your brain alone weighs 10 tons at that moment, equal to its normal weight when it hits the ground.
Consider this: if someone weighing 110 pounds falls 10 feet with a deceleration of 1 foot, the force generated from the body equals about 1,210 pounds.The force generated is the force from the body.This force equals about 1,210 pounds.

Rapid deceleration—what happens when the body falls and hits suddenly—causes cells to rupture.Cells can rupture.Blood vessels break open like cells. This stops oxygen from reaching the body. Without oxygen, organs, including the brain, stop working.

Once blood vessels rupture and the heart briefly pumps blood, the result can be internal bleeding.Internal bleeding occurs.A bad fall causes bleeding all over the body, including the brain. Damaged blood pathways let blood pool inside the body.
Even without clear external injury, the body may get this life-threatening condition after severe trauma.Severe trauma results., such as through falling, a car accident, a hard punch, or having a heavy object dropped on the body.

Some people think landing in water cushions a fall from a great height. Landing on water causes damage equal to landing on concrete.Landing on concrete is the same as falling in water.. The water surface acts solid when your body hits it. Anyone who belly flops knows this.
Depending on impact force, solids like rocks or people disperse, acting like water. Water acts like a solid when hit with great force.

How you land changes your skull's outcome. Your skull could crack into pieces. This injury risks brain and spine damage that stops life. Therefore, one should wear a helmet.Wear a helmet to prevent your skull from shattering.when riding a motorcycle, bicycle, or skateboard.
However, a helmet cannot stop serious injury if you fall from a building's height.

Although the brain is small in body mass, it needs about 20 percent of the body's energy. While ourYour reaction times might be faster than you think.The time we feel pain or process trauma slows down when we fall fast—like 250 mph. Signals travel through our brains at about one meter per second.One meter per second..
Depending on the fall's length, one might hit the ground before processing the event.

People spend much time inside homes and other spots. Dangerous falls happen most often indoors. The Centers for Disease Control and Prevention (CDC) reports unintentional falls cause over30,000 deaths occur.America sees these deaths yearly. That number beats car accidents. The CDC points out most people inEmergency rooms see these injuries.Emergency rooms treat injuries from falls.
People usually fall in everyday settings when they suffer fatal injuries from losing balance. WetBathroom environments present risks.public shopping areas are especially dangerous.

The surface a fall hits affects blood spatter. Even if a person lands whole, the impact causes outside harm. These injuries can lead to severe bleeding because blood vessels cannot hold the blood.
An adult human has aboutYou might spill 1.2 to 1.5 gallons.The body holds aboutthe pattern of blood spatterForensic analysts use this pattern to figure out how high, how hard, and how fast someone fell.

A human's terminal velocity, the fastest fall speed, is aroundYour standard terminal velocity is 120 mph.. Calculating wind resistance against a flat body determines this. If you wear an aerodynamic latex suit and dive headfirst, instead of belly flat and parallel to the ground, you might hit speeds ofYou can reach 200 mph..
If someone falls free with arms and legs spread, the limbs catch wind resistance, slowing the faller. A ball shape increases terminal velocity.

Falling, short or long, can leave no visible outside injuries. This meansNo visible trauma may appear.on the body, nor any blood spatter for forensics to examine. A fall may cause all internal injuries, or zero injuries if the landing is soft.
A firefighter jumping from a tall building into a safety net usually avoids injury. However, falling from a great height and hitting concrete is more likely to cause life-threatening harm.

Research shows drinking makes survival from a serious injury more likely, though scientists do not know the exact reason. One idea suggests intoxication lets your body relax, letting you absorb the impact, unlike a tense sober person.
A study at the University of Illinois at Chicago calls this the "Drinking offers a protective effect.." But this is a working idea; the scientific community has not confirmed it yet.
