Dead body heavier than a live one?

In summary, the conversation discusses the idea that a dead body may weigh more than a live body. However, this is not true as a live body is able to distribute weight and assist in lifting, while a dead body is simply a dead weight with no support. This may give the perception of being heavier, but it actually weighs the same.

Hi

Happened to hear that a dead body may weight more that a live body. Now is that true and if it is, then why?

Thanks in advance,

A dead body has no weight difference compared to a live body. However a live body is able to do things that a dead body can not do. Such as:
Distribute weight to change centre of gravity.
Assist in the lift
Or even distribute their weight across different areas of your body (I.e. holding on around your neck would distribute the weight even more.)

A dead weight basically means that the centre of gravity is where ever you are supporting the weighted load with no support from it. It feels heavier, but it weighs the same.

Yeap, always thought it was the sandbag effect.

Thanks.
 

1. Why is a dead body heavier than a live one?

A dead body is heavier than a live one because when a person dies, their body undergoes a process called rigor mortis. This is where the muscles in the body stiffen and become rigid, causing the body to feel heavier.

2. How much heavier is a dead body compared to a live one?

The weight difference between a dead body and a live one can vary depending on factors such as the person's age, body composition, and the stage of rigor mortis. On average, a dead body can be up to 2-3 pounds heavier than a live one.

3. Does the weight difference between a dead body and a live one affect how it is handled?

Yes, the weight difference can affect how a dead body is handled. Due to the added weight and stiffness, it may require more effort and assistance to move a dead body compared to a live one.

4. How long does rigor mortis last and how does it affect the weight of a dead body?

Rigor mortis typically begins within 3-4 hours after death and can last up to 36 hours. During this time, the body will continue to stiffen, making it feel heavier. After rigor mortis passes, the body will gradually return to its normal weight.

5. Can the weight of a dead body be used to determine the time of death?

No, the weight of a dead body cannot be used to determine the time of death. Rigor mortis and other factors such as body composition and temperature can affect the weight of a dead body, making it an unreliable method for determining time of death.
