Experts Are Shedding Light on the ‘Death Rattle’ Phenomenon Before Passing

In the final 24 hours of life, many experience a phenomenon known as the death rattle, a noise caused by changes in breathing and secretions in the throat. This natural process, though unsettling to hear, does not cause pain or discomfort to the individual.

What Is the Death Rattle?

The death rattle occurs as swallowing ability diminishes, allowing secretions to build up in the respiratory tract. The sound is often described as a crackling or wet gurgling noise. Fever and temperature fluctuations are also common at this stage, as the body loses the ability to regulate core temperature.

How Long Does It Last?

The average lifespan after the onset of the death rattle is about 25 hours, though it can last longer in hospice care compared to hospital settings.
