The idea that the soul remains in the body for three days after death is an ancient belief, present in various cultures and religions. Some spiritual traditions claim that during this time, the soul adjusts to its departure, observes what is happening around it, and bids farewell to loved ones. But what does science say about this? Is there any evidence of consciousness after death?
Below, we explore both the spiritual perspective and the most recent scientific findings about what happens in the moments following death.
The “3 Days” Belief: A Spiritual Transition
Many traditions maintain that the soul needs a transition period to fully detach from the physical body:
In Tibetan Buddhism, there is talk of the bardo, an intermediate state that can last up to 49 days, but where the first few days are crucial for the soul to understand that it has died.
In Judaism, it is believed that the soul lingers in the body for three days before beginning its journey to the afterlife.
In some Latin American folk beliefs, it is said that “the soul doesn’t know it has died” and remains near the living for a short time, especially if death was sudden.
These interpretations, although symbolic, have one thing in common: the soul needs time to detach itself and accept its new state.
And what does science say about consciousness after death?
Science cannot speak of the “soul” as a spiritual entity, but it has begun to study what happens to consciousness and brain activity after cardiac arrest. What they have discovered is surprising:
1. Consciousness can last for a few minutes after clinical death
Recent studies have shown that some people who have suffered cardiac arrest and were resuscitated clearly remember what happened during those minutes. They report seeing their body from outside, hearing voices, or feeling a great peace. Science has begun to refer to this as near-death experiences (NDEs).
2. Brain Activity After Death
Research conducted in hospitals has detected flashes of brain activity even minutes after the heartbeat stops. This indicates that consciousness, or at least some form of perception, may persist beyond the point at which a person is considered clinically dead.
A 2023 study published in Resuscitation analyzed cases of cardiac arrest and concluded that, in some patients, a “brain signature associated with conscious perception” was recorded, suggesting that something happens in the brain that is not yet fully understood.
How does this relate to the idea of the soul?
Although science cannot confirm the existence of a “soul,” the aforementioned findings allow us to consider the possibility that consciousness does not immediately cease. This aligns, symbolically, with the belief that the soul needs time to depart.
The idea of the three days could be interpreted as a cultural or spiritual framework that expresses a real, as yet unknown, process of disconnection between the body and consciousness.
Between Faith and Science
The belief that the soul takes three days to depart is part of an ancient wisdom that attempts to make sense of what happens after death. Science, for its part, is beginning to discover that human consciousness is far more complex than previously thought, and that perhaps it doesn’t disappear instantly.
Although there are still no definitive answers, the dialogue between spirituality and science remains open. Far from contradicting each other, both paths may be observing the same phenomenon from different perspectives.
