Near-death experiences can be reminiscent of religious visions, yet people across different faiths as well as those with no declared religion have reported them.

A near-death experience is a phenomenon reported by roughly 5% of the population, typically occurring after a traumatic physical event or a brief clinical death.

Accounts of near-death experiences share similarities with hallucinogens, with reports of mystical-like states of consciousness across both contexts.

Near-death experiences have been reported across cultures for millennia.

A radiation oncologist has studied near-death experience reports for over 25 years and compiled around 4,000 accounts in the hopes of finding more patterns that would reveal insights about consciousness and humans' final moments before or around death.

Medical advances that manage to resuscitate people from comas and cardiac arrests have enabled new research into the brain activity of people experiencing near-death experiences and a new (contested) explanation about why they occur.

A leading expert on near-death experiences, psychiatrist Dr. Bruce Greyson, says that during his decades of research on this topic, this area of research has become far more mainstream and accepted as a rigorous area of inquiry.

The body's response to cardiac arrest has been linked to near-death experiences.

What happens in a dying brain?

Near-death experiences usually happen during death or on the border of life and death when a person isn't understood to be conscious. This article details the science of what's going on with the brain during NDEs.

Listen to an avowed rationalist discuss his frightening near-death experience visions from 2020 and how it changed his life outlook.

NDEs typically change people's outlooks drastically and can prompt depression

The phenomena are regularly categorized as hallucinations, but some specialists are interested in their psychological nuances. Many survivors report feeling less anxiety about death, though some surveys show the experiences can increase physiological sensitivities.

The oldest medical report of a near-death experience dates to around 1740.

Some scientists argue NDEs are constructed by the brain, not actually experienced

Despite the powerful memories associated with NDEs, scientists question the idea that the experiences prove consciousness endures after death, opting instead to find physiological explanations for common reports of out-of-body experiences, euphoric and lucid thinking, and more.

The main criticism of a recent neurophysiological explanation for near-death experiences is that these events are too complex to be explained as a neurochemical response to an oxygen-deprived brain.

Brain activity sometimes goes into overdrive around the point of death according to researchers' recent analysis of patients' brains before and after they were taken off their ventilators.

There are psychological benefits to believing in spirits

A number of psychologists believe religion helps subdue our fears of death by giving us a sense of what’s to come and, therefore, a sense of control over how to ensure the best possible outcome.

The University of Virginia has the nation's most established near-death studies division, but institutions including the University of Southampton, the University of Connecticut, and the University of North Texas have also explored the field.

A 'paranormal activity' unit at the University of Virginia studies challenges to mainstream scientific ideas about human consciousness.

Scientists are studying dying patients' brain activity in the final moments of life

In the final moments of life there are distinctive bursts of coordinated neural activity. Researchers are interested in parsing that data to better understand the dying process and also exploring how this data relates to our understanding of consciousness.

Psychiatrist Bruce Greyson created a scale to identify and rate NDEs

Researcher Bruce Greyson is one of the world’s leading experts on near-death experiences. This article explores what the field of NDE research has learned over the last five decades, discusses the difficulties of studying such a controversial topic, and outlines what we’ve ruled out as the cause of these events.

Terminal lucidity is the phenomenon of sudden, heightened mental clarity when on the verge of death

The "Let's Talk Near Death" podcast explores phenomena around the end of life, inviting guests to recount their own experiences. This episode focuses on the phenomenon known as "terminal lucidity," where patients experience clarity, vivid memory recall, and more, typically following a heart attack, stroke, or other trauma.

Meet the Dutch cardiologist who believes consciousness can exist outside the body

Dutch cardiologist Dr. Pim van Lommel conducted one of the largest studies of near-death experiences following cardiac arrest, publishing the results in the prestigous journel The Lancet. He later went on to argue (to significant criticism from peers) that his findings suggest consciousness can exist outside the body.

Afterlife traditions help some humans process death

Watch this video discussing concepts of the afterlife presented through an anthropological lens about one family's experience and traditions passed down from one generation to another.

Researchers have investigated the benefits of extreme pain rituals, exploring how and why we engage in these events when humans generally naturally avoid pain and perceive it as a negative experience.

What can psychedelics teach us about dying?

Psychedelics have made their way into the world of licensed mental healthcare, and the drugs have been proven to help people process and lessen anxiety and depression. What does this mean for people with terminal illnesses who are afraid of death?

How seizures (potentially) alter consciousness

Seizures occur when intense electrical activity floods the brain, prompting significant loss of self-control and a variety of sensory disruptions and hallucinations. Cultures interpret the episodes differently, with many contemporary norms viewing them as negative while others characterize them as intense spiritual occasions. Author Fyodor Dostoyevsky viewed his seizures this way, as well as cultures in Mongolia, some Shamanic indigenous religions, and others.

Exploring a new generation's search for religion

Amid the historical trend toward secularization, young people still search for religion. Lamorna Ash wrote a book on this revival of interest in faith and spirituality, exploring the importance of community and identity in religious conversion. Listen to her experiences and investigations in this podcast.

Ghost stories can help us process death

Scholar Coya Paz’s research into ghost stories indicated that people often use them to grieve and remember tragic histories. Paz notes that specters in stories almost always demand to be acknowledged. She also shares the three most common types of ghosts we hear about are either vengeful, unwelcoming, or comforting.

Emotional relationships with God affect grief

A study published in 2020 examined how internal, emotional relationships with God—rather than external characteristics of one's religiosity like weekly workshop attendance or attire—affected grief and adjustment among bereaved parents.

Dreams have long been used for religious and political power.

Thanatology is the study of death and dying.

What do your dreams mean, according to science

Humans have been interpreting dreams as signs from deities, spirits, or the psyche for ages, and research shows that reflecting on and analyzing one's dreams can be beneficial. In alignment with dreams' elusive nature, they have no objective or clearly assigned meaning. However, variations of common dreams, such as a surprise exam in a forgotten class, are rife with shared primal fears.

The neurobiology of meaningfulness: the benefits of psychedelics

Psychedelics produce powerful emotions in its users, including a profound sense of meaningfulness. The philosopher William James called this sense "noetic" in the late 19th century, but for decades researchers avoided studying the effects of such drugs on the brain. However, the recent resurgence in psychedelic research has heightened interest in the relationship between this noetic sense resulting from the therapeutic use of drugs. Learn what researchers have found out here.

Studies of psychedelic use may help shed light on the nature of consciousness

The nature of consciousness—what it is, where it comes from, and how it manifests as moment-to-moment experience—remains under debate by scientists. Recent studies show psychedelics were found to boost low-frequency brain signals known as delta waves, a behavior also seen during dream states.

How science explains déjà vu

Take a fun look at the science explaining the odd experience of déjà vu, which some theories suggest is actually a sign of a healthy brain.

The history of ghosts, explained

The afterlife has perplexed humans across different periods, cultures, and belief systems. The desire to understand what comes next is often explored through the telling of ghost stories. Learn more about the spooky phenomena here.

The idea of resurrection was not common at the time of Jesus' death

NT Wright, a leading New Testament scholar, argues that first-century Jews held a wide spectrum of beliefs about the afterlife. This included that the early Christian claim of one individual rising bodily from the dead, ahead of the general resurrection, was without precedent in Judaism or the wider Greco-Roman world.

Christians believe Jesus was resurrected, body and all

The Christian doctrine of bodily resurrection—that Jesus rose physically, not as a ghost or spirit, and that believers will do the same at the end of time—was found absurd by ancient Greeks. Plato preferred a disembodied soul escaping the body. Paul, on the other hand, staked the entire faith on it. Theologians describe the resurrected body as the same body, but as a transformed one.
