What does the last glimmer of light mean

In our lives, many patients will experience a terminal lucidity before they die. The so-called terminal lucidity means that the patient's condition will suddenly improve, but this improvement is only for a moment, and the patient will become particularly energetic, and then the condition will become serious again. In fact, sometimes a terminal lucidity can bring people a glimmer of hope, because everyone will think that they will be happy when their condition is improved. So what does a terminal lucidity mean?

The last breath of life is a common natural phenomenon. When the sun is about to set in the west, the sky will be bright for a short time due to the reflection of the sunset light, and then quickly become dark. In the past, there were no electric lights, and people lit incense oil lamps or kerosene lamps. When the oil in the lamp was about to burn out, it would suddenly light up and then go out. That's because the last drop of oil loses its adhesion or pulling force and rises very quickly, so it suddenly lights up. When we use electric lights now, when the filament life is about to end, the tungsten filament burns and the light bulb will suddenly light up, and the bulb will be scrapped. These can all be seen as a last-glow phenomenon.

People also experience a last-minute lucidity before they die. For example, a patient who has been in a coma for a long time may suddenly wake up and even have a brief conversation with his relatives; a person who has lost his appetite and refuses to eat or drink may suddenly want to eat. These phenomena of "improvement" of the disease are an illusion, giving people the wrong impression that the patient is out of danger. However, experienced people can tell at a glance that this is a last burst of vitality, a signal from the patient to say goodbye to his loved ones.

Why does backlighting occur?

Why do people have a moment of lucidity before they die? Medical science tells us that it is mainly due to the hormones secreted by the adrenal glands. The adrenal glands are a pair of very important endocrine glands, which are structurally divided into the cortex and medulla. The cortex secretes glucocorticoids and mineralocorticoids. Among them, glucocorticoids are mainly used for "emergency situations". They can quickly relieve symptoms and help patients through the critical period through anti-inflammatory, anti-toxin, anti-shock, and anti-allergic effects. The adrenal medulla secretes adrenaline and norepinephrine, both of which can excite the heart, constrict blood vessels, and increase blood pressure, thus saving people from shock.

When a person is on the verge of death, under the control of the cerebral cortex, it quickly instructs the adrenal cortex and medulla to secrete the above hormones, which mobilizes all the positive factors in the body and causes the patient to go from coma to consciousness; from being unable to speak to being able to talk a few sentences and explain his last wishes; from not being able to eat to wanting to eat and drink. These are all the effects of endocrine hormones under the command of the central nervous system.
