Have you ever wondered what happens to our bodies after we die? It can be a bit difficult to imagine, and maybe even scary. But it's something that is common to all of us, an inevitable part of life. So, let's talk a little bit about what "dying" really is, how the body changes at that time, and what its characteristics are, okay? Knowing these things can help us look at this process with a little more understanding.
Simply put, death is the moment when the processes necessary for life in our body stop. You take your last breath. Your heart stops beating. Your brain stops functioning. Also, other vital organs like the kidneys and liver stop working. All the systems in the body that depend on these organs gradually become inactive. Then, the body is no longer able to carry out the ongoing processes that make us "alive."
Death is not a single event, but a continuous process. If we think of "dying" as a series of events, it is easier to understand what happens to the body as it transitions from life to death. From the first breath we take to the last, our existence depends on the processes that the body itself initiates and continues. So, dying is one of the last essential processes that our body performs for us.
How long does it take to die?
It's hard to say exactly when this will happen. It varies from person to person. How long it takes for your body to die depends on many factors, including your health, the treatment you receive, and the cause of death. For example, if left untreated, sudden cardiac arrest can result in death within minutes. However, if you have a chronic illness, it can take weeks, or even months, for your body to die.
Many of the leading causes of death worldwide, such as heart disease, chronic lung disease, and cancer, now have treatments. These treatments not only delay death, but also prolong the process of dying. Because this process occurs slowly, it is also easier for us to recognize the common signs that death is approaching.
What happens to the body before death?
When death occurs due to long-term illness or natural causes, various changes occur as the body's vital processes gradually slow down before they completely stop. Let's take a look at what they are.
Sleeping too much and exercising too little
When a person is nearing death, they are not sleeping to rest their mind and body. In fact, it is because their body no longer has the energy to do any activity. The heart’s ability to pump oxygen-rich blood throughout the body gradually decreases. When there is not enough oxygen, the cells in your body do not have the energy to keep you awake and active. Therefore, rest is an important part of the dying process.
Decreased appetite and thirst
A dying body does not need the same amount of nutrition as a healthy body. Your appetite may decrease significantly in the days, weeks, or even months before death. Your digestive system may have difficulty digesting the food you eat. Eventually, you may lose your appetite completely.
From the day we are born, we learn from our parents and caregivers that feeding is a way of showing love and a necessity for survival. Therefore, your loved ones may force you to eat. However, a doctor can guide you on whether you need to use an artificial feeding device, for example, a ``Feeding Tube``, or if your digestive system is too weak to digest food.
Inability to control bowel and bladder control
As the digestive system slows down, it can be difficult to pass stools. Constipation is a common symptom among people who are dying. Incontinence can also be a problem, as can the muscles in the pelvic area that control urination.
There are stool softeners to help relieve constipation. Medical devices like Foley Catheters and incontinence pads can help keep the bed clean.
Muscle and skin weakness
It is common for people to lose weight and lose muscle mass as they approach death. Changing positions in bed or even talking can be an unbearable strain on the muscles. The skin becomes thinner because new skin cells do not replace the dead cells as quickly as they should. Thin skin can be easily damaged by bruises, cuts, and bedsores.
Your medical team and loved ones can check your skin for infections, and change your position to stop your skin from being too tight against the bed. You can also apply moisturizer to your skin regularly to prevent dryness and minimize the risk of sores.
Social isolation and loneliness
It is normal for a dying person to lose interest in things they once enjoyed. They may prefer to be alone rather than socialize with others. This reduction in contact with others does not mean that they have lost their love for friends and family. As the body changes, so do their needs.
Irregular or decreased vital signs
Your vital signs are your temperature, pulse, respiratory rate (breathing rate), and blood pressure. These values measure the health of your vital organs, such as your lungs, heart, and brain. As you die, your body temperature drops, and your skin may feel cold and clammy to the touch. Other values may become irregular or change unpredictably. This is because, as you approach death, these vital organs are still trying to keep you alive. As you approach your final hours, your breathing rate gradually slows.
Restlessness and agitation
Feeling suddenly energized after a long sleep, or feeling restless, can be a sign that death is approaching. You may feel like you can do things that you really can't. You may try to get out of bed, remove medical equipment such as an ``(IV - Intravenous Drip)``, and become angry at those who are trying to help.
Changing perception of the surrounding environment
Your brain may start to perceive sensory information (such as what you see, hear, smell, etc.) differently than before. For example, a sound that you previously thought was normal may seem scary or threatening. You may mistake one person for another. You may see and feel things that others around you cannot see or feel. These changes may be more noticeable at night than during the day.
Some studies have shown that when death approaches, the brain suddenly releases a large amount of chemicals called neurotransmitters. This can lead to heightened sensations and a state of heightened awareness or hyperreality. For example, people who are dying often report seeing bright lights. They may even see a journey to reunite with a loved one who has passed away.
Periods of unconsciousness
As death approaches, you may fall into a state of unconsciousness, like a ``coma'' or a dreamlike state. You may wake up later, but you may have no memory of being unconscious. As you near the end, you will remain in this unconscious, restful state for a long time.
Research suggests that even when your body is in a state of unconsciousness, you can still feel the comforting touch of your loved ones and hear what they are saying. The two senses that ultimately disappear when we die are touch and hearing.
Changes in breathing pattern
Your breathing pattern can tell you how close you are to death. While normal, steady breathing is a sign of life and good health, erratic breathing is often a sign of failing health or death. As death approaches, the time spent without breathing may be prolonged. If saliva collects in the back of the throat (because the throat muscles are not strong enough to swallow it), a rasping sound may be heard when breathing. This sound is often called a "death rattle."
Finally, you take your last breath.
What happens to the body at the moment of death?
At the moment of death, your body's vital processes completely stop. Your heart stops beating, you stop breathing, and your brain completely stops functioning. Although some studies have shown that there may be some brain activity for a few minutes after someone is declared dead, this brain activity is not consciousness or awareness. It does not mean that someone is aware that they are dead.
These are the signs of death:
- There is no pulse.
- No breathing.
- Reflexes do not respond when tested.
- The pupils of the eyes do not shrink in bright light.
What happens to the body after death?
After you die, your body undergoes a series of changes as it adjusts to its new state. These changes occur quickly, within a few days.
- Muscles relax: Immediately after death, muscles relax, releasing pressure on the bowels and bladder. As a result, many people pass stool and urine when they die. The skin may also sag, exposing the underlying bone structure.
- Body temperature decreases: Body temperature gradually decreases at a rate of about 1.5 degrees Fahrenheit (0.83 degrees Celsius) per hour. Eventually, the body temperature becomes equal to the temperature of the surrounding environment.
- Blood pools downward: Gravity causes blood to pool downward, toward the ground. The skin may appear purple-red where the blood pools.
- Rigor Mortis: The muscles of the face and neck stiffen first. The stiffness then spreads to the trunk of the body, gradually spreading to the arms and legs, and then to the fingers.
- The body becomes loose again: A few days after death, the body's tissues begin to decompose, causing the stiff parts to loosen again.
Is dying painful?
It's hard to say for sure, because it depends on many things. Pain is a part of life, and it can also be a part of death. Just as we experience different types of pain (from the nature of the pain to its intensity) in life, we can also experience different types of pain in death. It often depends on the cause of death and whether pain medication is available. For example, if you die suddenly, you may not feel any pain at all.
Often, dying bodies fight to stay alive. This survival instinct, built into our bodies, can be painful without painkillers. For example, a body that is losing blood to a life-threatening extent will automatically divert its limited blood supply to vital organs. This response keeps those organs alive, but the parts of the body (like arms and legs) that are not receiving blood can hurt. In emergencies like these, medical professionals are trained to try to save your life as well as reduce your pain.
Medical professionals who provide hospice care are experts in providing you with the comfort and care you need when you are dying. They identify the life-sustaining responses that can cause pain in your body and provide comforting medications to help with them.
Take-Home Message
Dying is a natural process that we all go through. However, it is normal to be afraid of death because of the unknown. You may wonder how it will feel for you or a loved one to die. You may have questions about whether it will be painful or how long it will take from the first labored breath to the last. These questions are difficult to answer directly.
But having a clear understanding of what it's like to die can help you cope with your own death or the death of a loved one when the time comes. Also, having an idea of what to expect can help you be more capable and understanding when providing comfort to a dying loved one.
I hope this information is useful to you. Remember, it is very important to talk about and be aware of these things.
