They don't 'shrink' but they do get shorter. The compression of the discs in the back bone result in less height then in the morning. It returns after allowing them to get relief from the compression of gravity by sleeping.

Can you shrink?

You can not shrink, the reason people say older people shrink is because they get a hunch in their back.


How much do you shrink in the day?

On average, a person can shrink between 0.5 to 1 centimeter over the course of a day due to compression of the spinal discs. This shrinkage typically occurs because of factors such as gravity and fluid redistribution in the body.


Do tall people shrink more than short people?

Yes, taller people shrink more due to gravity pulling on their vetebras and bones. Also, many tall people have some form of scoliosis or other curvature of the spine.


Why do you get wrinkles?

When we are born we are new to the Earth. But as time progresses gravity has a better "hold" on us. Because of this our skin will be pulled downward. THis is known as wrinkling. This is also why older people tend to "shrink". :)


Does gravity effect your height laying down?

When lying down, gravity still affects your height, but the effects are minimal because gravity is acting evenly across the body. When standing, gravity compresses the spine slightly, causing a temporary decrease in height.


Can people shrink?

People shrink as they age. It seems strange, but there are simple scientific explanations for why you get smaller as you get older. It's all in the discs. Over time, discs in the back, which act as shock absorbers and are filled with a gel-like fluid, begin to dehydrate. This process causes the discs to shrink, and the spinal column compresses.


Why do you shrink at night?

Your spine compresses during the day due to gravity, so when you lie down at night, the discs in your spine have a chance to rehydrate and expand, which can make you a bit taller in the morning. This temporary height increase is lost throughout the day as gravity compresses your spine again.


Do you shrink on Saturn?

Saturn has more gravity so it would crush a person.


Can you shrink people?

The answer is no. It is physically impossible to shrink as if you would shrink them like in the movie "Honey I Shrunk the Kids". The reason being because the amount of brain cells would exponentially decrease, causing whoever is shrunk to become "dumber". your liver and other organs would be the size of a few cells and you would be crushed under gravity. This is also the reason that you cannot also have a giant amoebae the structural biology dose not work :)


Is it possible to shrink?

No, because you would lose your strength and would die of metabalic congestion. Yes, as people get older their back bone continues to be pulled closer to earth by gravity and they are usually a few inches shorter than they were at the peak in their life.


Why do elderly people shrink over time?

In our back's we have intervertebral discs. As people age these discs get smaller. So in a sense, yes, one can say that elderly people shrink.


What Effect of gravity?

Gravity causes older people to shrink. Answer Had to chuckle at the first answer though it is not true. Gravity is that force , said to originate from the center of the earth, which affects everything within its influence by attracting it to the earths center. Luckily we have a hard mantle beneath our feet that prevents this from happening.
