- Stage 1 Fresh (1-2 days) This stage begins almost instantly from the moment of death. As the heart stops beating, the body’s cells gets deprived of oxygen and pH changes occurs.
- Stage 2 Bloated (2-6 days) This stage of decomposition includes the first visible signs of decay, namely the inflation of the abdomen due to a build-up of various gases produced by bacteria inside the body.
- Stage 3 Decay (5-11 days) The previously inflated carcass now deflates and internal gases are released. As the tissues break down the corpse will appear wet and strong odours are very noticeable.
- Stage 4 Post-Decay (10-24 days) By the time this stage is reached, decomposition slows, as most of the flesh has been stripped from the skeleton, though some may remain in denser areas such as the abdomen.
While the rate of human decomposition varies due to several factors, including weather, temperature, moisture, pH and oxygen levels, cause of death, and body position, all human bodies follow the same four stages of human decomposition.
Jul 6, 2022 · After 365 days in the coffin, different bodies will have decomposed differently. A body that was embalmed and buried in a steel casket in a cool, dry climate may still be in an early stage of decay, while one in a pinewood box in a hot climate may have already begun to skeletonize.

- 4 Postmortem Stages of Death. After death, the body undergoes a series of changes that occur in a timely and orderly manner. These stages are also affected by the extrinsic and intrinsic factors of the corpse.
- Pallor Mortis. The first change that occurs in a corpse is the increased paleness in the face and other parts. This is due to the cessation of blood circulation.
- Algor Mortis. Humans are warm-blooded organisms, which means that we maintain a constant internal temperature, regardless of the outside environment. The brain is our thermostat, and the circulatory system is the main heat dissipator.
- Rigor Mortis. Immediately after death, a corpse will go flaccid. All the muscles will become relaxed and limp, but the whole body will stiffen after a few hours.
Nov 25, 2013 · During the first stage, called the fresh stage, usually lasting a day or two, the body doesn't change much outwardly, but chemicals released during cellular death begin to attract flies. The second stage begins when the body begins to swell and is called putrefaction or the bloated stage.
Mar 21, 2016 · Here, scientists study how the human body deteriorates in our country’s unique climatic conditions, how different circumstances (whether the body is in the sun/shade, buried/surface, clothed/unclothed etc.) affect the decomposition process, and how the smell of decay changes over time.
