Like birth, dying is a physical process consisting of certain stages. The pace of this process can vary, and sometimes even medical intervention is needed for relief. According to a scientific article published on BBC Science Focus, most people lose interest in eating and drinking as they approach death. Dying people also constantly lack energy, so they spend less and less time being cheerful. At the same time, for them, sleep means falling into an unconscious state for longer periods of time.

As a person dies, their heart begins to beat more slowly, their blood pressure drops, and their nails fade. A person’s internal organs work increasingly worse, blood pressure drops. Sometimes, in the last moments of his life, a person may feel anxiety, confusion, gradual sinking into unconsciousness.

As scientists report, there is currently no proven way to understand what people are feeling at the time of death. Recent research shows that the unconscious brain reacts to noise in the room even before death, but scientists do not know what these sounds mean for a person.

Kathryn Mannix explains that unconscious people’s breathing follows automatic patterns created by the respiratory center in the brainstem. Since the deceased cannot feel his mouth or throat, he may breathe hard and noisily, and saliva may be released from the back wall of the throat, but this does not cause discomfort to the person.

Breathing moves from deep to shallow and from fast to slow in repetitive cycles; Then it slows down and becomes superficial. There may be pauses and then breathing stops completely. After a few minutes, the heart stops beating as the oxygen in the lungs is depleted. Source
