One researcher found air pilots who experienced unconsciousness during rapid acceleration described near-death experience-like features, such as tunnel vision. Researchers have also explained near-death experiences via cerebral anoxia, a lack of oxygen to the brain. Overall, chemical-based theories lack precision and can’t explain the full range of near-death experience features people experience.Įndorphins, natural DMT, lack of brain oxygen, and brain malfunctions are all explanations for the phenomenon. ![]() However, there is no conclusive evidence to support this view. According to Strassman, the body has natural DMT released at birth and death. ![]() Rick Strassman, a professor of psychiatry, observed in a study from 1990 to 1995 that people had near-death and mystical experiences following injection of DMT. Other theories suggest near-death experiences arise from dimethyltryptamine (DMT), a psychedelic drug that occurs naturally in some plants. Similarly, anaesthetics such as ketamine can simulate near-death experience characteristics, such as out-of-body experiences. Some researchers claim that endorphins released during stressful events may produce something like near-death experience, particularly by reducing pain and increasing pleasant sensations. Scientific author Carl Sagan even suggested that the stress of death produces a remembrance of birth, suggesting the “tunnel” people see is a reimagining of the birth canal.īut due to the fanciful nature of these theories, other explanations have emerged. Whereas scientific explanations for near-death experiences include depersonalisation, which is a sense of being detached from your body. Religious people believe near-death experiences provide evidence for life after death – in particular, the separation of the spirit from the body. This area of the brain is involved with processing sensory information and memory, so abnormal activity in these lobes can produce strange sensations and perceptions.ĭespite several theories used to explain near-death experiences, getting to the bottom of what causes them is difficult. The temporal lobes also play an important role in near-death experiences. While it’s unclear why there are different types of near-death experiences, the different interactions between brain regions produce these distinct experiences. Type two, involving the right hemisphere, is characterised by seeing or communicating with spirits, and hearing voices, sounds and music. Type one, which is associated with the brain’s left hemisphere, features an altered sense of time and impressions of flying. Neuroscientists Olaf Blanke and Sebastian Dieguez have proposed two types of near-death experiences. However, some near-death experiences are negative and include feelings such as lack of control, awareness of nonexistence, hellish imagery, or perceived judgement from a higher being. Most reported near-death experiences are positive, and have even helped in reducing death anxiety, affirming life, and increasing well-being. Children typically describe encountering friends and teachers “in the light”. For example, many Indians report meeting the Hindu king of the dead, Yamraj, while Americans often claim to have met Jesus. They’re surprisingly common, with a third of people who have come close to death reporting having experienced one.Ĭommon characteristics people report are feelings of contentment, psychic detachment from the body (such as out-of-body experiences), rapid movement through a long dark tunnel, and entering a bright light.Ĭulture and age may also influence the kind of near-death experience people have. It typically occurs in people close to death, or during situations of intense physical or emotional pain, but may also happen after heart attacks or traumatic brain injuries, or even during meditation and syncope (loss of consciousness due to a fall in blood pressure). What are near-death experiences?Ī near-death experience is a profound psychological event with mystical elements. But despite the seemingly supernatural nature of these experiences, experts say that science can explain why they happen – and what’s really going on. People who’ve had a brush with death often report seeing and experiencing life-altering events on “the other side,” like a bright white light at the end of a long tunnel, or being reunited with lost relatives or beloved pets. In our never-ending quest to understand what happens to us after we die, humans have long seen the rare phenomenon of near-death experiences as providing some hints. ![]()
