sudden spurt of vitality prior to collapse

Return light is a common natural phenomenon. When the sun is about to set in the west, the sky will brighten for a short time due to the reflection of the light at sunset, and then quickly go into darkness. Later, it is used to make people look better.

Scientific explanation reflection is also called "reflection". ① When the sun falls below the horizon, it makes the sky shine for a short time due to reflection. It is used to describe the brief excitement of people's spirit before death. ② It refers to the temporary improvement of things before they decline. ③ It means self-examination. return light is a common natural phenomenon. When the sun is about to set in the west, the sky will brighten for a short time due to the reflection of the light at sunset, and then quickly go into darkness. In the past, there was no electric lamp. People lit incense oil lamp or kerosene lamp. 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 fast, so it suddenly lights up. With an electric lamp, when the life of the filament is about to end, the tungsten filament will burn, and the lamp will suddenly light up, so the bulb will be scrapped. All of these can be regarded as the reflection phenomenon. people also have the phenomenon of returning light before they die. For example, patients who have been in a coma for a long time suddenly wake up and even have a brief conversation with their relatives; people who have lost their appetite and do not eat or drink will suddenly want to eat. The phenomenon of "remission" of the disease is a kind of false image, which gives people the illusion that the patient is in a better situation. The experienced people will know that it is a return of light and a signal for the patient to say goodbye to his relatives. Medical science tells us that it is mainly caused by hormone secreted by adrenal gland. Adrenal gland is a pair of important endocrine glands, which can be divided into cortex and medulla. The cortex secretes glucocorticoid and mineralocorticoid. Among them, glucocorticoid is mainly used for "emergency", which can rapidly relieve symptoms and help patients through the dangerous period through anti-inflammatory, antitoxin, anti shock, anti allergy and other effects. Adrenal medulla secretes epinephrine and norepinephrine, which can excite the heart, constrict blood vessels and raise blood pressure, so they can save shock. when a person is on the verge of death, under the control of the cerebral cortex, he quickly instructs the adrenal cortex and medulla to secrete the above hormones, which mobilizes all the positive factors of the whole body and makes the patient change from coma to soberness; from being unable to speak to being able to talk a few words and explain the future affairs; from being unable to eat to being able to eat and drink. These are all endocrine hormones under the command of the central nervous system It's working. there is also an important substance in human cells that can store and supply energy, called adenosine triphosphate (ATP). When the human body encounters strong stimulation, such as bacteria invasion, dying and other serious situations, ATP will be rapidly converted into adenosine diphosphate (ADP), and release huge energy, so that the body's various systems and organs quickly gain strong power, people will suddenly show extraordinary vitality, such as consciousness suddenly awake, limb strength enhancement, appetite increase. Of course, this kind of vitality supported by transient power can only be a flash in the pan, because the energy of ATP can only be maintained for a short time, so people's excitement before death will be very short. This is the principle of "return light". Shi Puji, Song Dynasty, wrote "all saints are words of dreams. Buddha and all living beings are added words. When they come here, they will shine back and let go."
