What Happens to Your Body in the First 24 Hours After You Die?

Many people want to know what happens to a loved one’s body in the hours after death, and whether there is anything they must do. This article gives a plain timeline. The changes are natural, and none of them requires action from the family.

What happens right away?

Once the heart stops, the body begins to change. Doctors confirm death by a set of checks, described in How Does a Doctor Know Someone Is Dead?. NIH’s StatPearls library calls cooling, color change, and stiffening the classical early changes after death, and they happen while the body is still in what experts call the fresh stage.

What happens in the first few hours?

The body begins to cool, and blood settles. Algor mortis is the cooling of the body until it matches the temperature of its surroundings. Livor mortis is a purple-red discoloration caused by gravity as blood pools in the lowest parts. Reference sources commonly report that it is visible by about 2 hours after death.

When do the muscles stiffen?

Within a few hours. Rigor mortis is the stiffening of the muscles. It starts in the small muscles of the face about 2 hours after death, spreads to the arms and the large leg muscles, and is complete by about 6 to 8 hours. The stiffness lasts for roughly another 12 hours, up to about 24 hours after death. Then it fades, and is usually gone by about 36 hours. Livor mortis typically becomes fixed after roughly 8 to 12 hours, according to reference sources. For more detail, see Rigor Mortis, Livor Mortis, and Algor Mortis.

Does it happen the same way for everyone?

No. Temperature, body size, and other factors change the timing. StatPearls notes that estimating time since death is not exact, and experts combine several signs.

Do families need to do anything straight away?

Not usually. A New South Wales health guide for an expected death at home says you do not have to do anything straightaway, and it is fine to spend some quiet time with the person. The Australian Government’s carer site says there is no rush to move the body, and that you can call a funeral director when you are ready. The Hospice Foundation of America says that when a hospice patient dies at home, the family should call the hospice, not 911. The hospice nurse confirms the death and completes the legal paperwork, and can help with calling a funeral home.

Why do funeral homes and hospitals act fairly soon?

Because the changes continue. Practical steps, such as transport and, if chosen, embalming, are part of caring for the body; see Embalming and Caring for the Body Before the Funeral Home Arrives. For what to do and who to call, see Who to Call in the First 24 Hours.
