No, you don't age slower in a coma; your body still undergoes normal biological aging processes, but a coma involves severe brain dysfunction, often with underlying injuries or illnesses, affecting consciousness and bodily functions, though some hormonal cycles might pause depending on brain impact. While it feels like time stops, your cells continue to divide, tissues wear down, and you still age chronologically, but the quality of life and recovery depend heavily on the coma's cause and duration, with potential for long-term deficits.
Because astronauts like the ones on the International Space Station (ISS) are moving so quickly, they're also aging a bit more slowly than the rest of us. Due to a principle of physics known as time dilation, after a six-month stint on the ISS, returning astronauts are just a tiny bit younger than the rest of us.
Symptoms of coma
They may be breathing unusually. They may be holding their body in an unusual posture. Their pupils may be affected in a number of different ways. For example, one pupil is larger than the other or both pupils are constricted.
Prognosis (outlook for recovery)
Comas can last from days to weeks while some severe cases have lasted several years. Recovery depends, to a considerable extent, on the original cause of the coma and on the severity of any brain damage.
A coma doesn't usually last longer than several weeks. People who are unconscious for a longer time might transition to a lasting vegetative state, known as a persistent vegetative state, or brain death.
Some people will make a full recovery and be completely unaffected by the coma. Others will have disabilities caused by the damage to their brain. They may need physiotherapy, occupational therapy, psychological assessment, and support while they're recovering. They may also need care for the rest of their lives.
Keeping them alive requires good basic care (such as turning and changing position to manage skin integrity), a feeding tube, intermittent antibiotics for infections and perhaps some ongoing mechanical ventilation support (such as oxygen at night).
Patients are only kept in an induced coma for as long as is required, which can range from a matter of hours to several weeks. Anaesthetic medicines are infused through drips and the experienced nursing team monitor and adjust the rates of these infusions according to several factors.
NDEs can be experienced in a variety of states: coma, anaesthesia, syncope or even orgasm. The phenomenon is still poorly understood, but scientists today explain it as the synergy of a spike in cerebral electrical activity and the release of certain hormones.
Elaine Esposito (December 3, 1934 – November 25, 1978) held the record for the longest period of time in a coma according to Guinness World Records, having lost consciousness in 1941 and eventually dying in that condition more than 37 years later.
Even in a coma, some women still have their periods – bodies doing their own thing, no rules.
Whether they dream or not probably depends on the cause of the coma. If the visual cortex is badly damaged, visual dreams will be lost; if the auditory cortex is destroyed, then they will be unable to hear dreamed voices.
Annie Shapiro (1913–2003) was a Canadian apron shop owner who was in a coma for 29 years because of a massive stroke and suddenly awakened in 1992. After the patients in the true story Awakenings, Shapiro spent the longest time in a coma-like state before waking up. Her story inspired the 1998 movie Forever Love.
Number of hours in 10 Earth years: 87660 hours. 1 hour on Miller's planet is equivalent to 7 Earth years, which is equal to 61320 hours (7 X 365.25 X 24 = 61,320).
The magnitude of this scale factor (nearly 300,000 kilometres or 190,000 miles in space being equivalent to one second in time), along with the fact that spacetime is a manifold, implies that at ordinary, non-relativistic speeds and at ordinary, human-scale distances, there is little that humans might observe that is ...
Answer 1: It is true that time slows down for someone who is moving at almost the speed of light, and slows down more as they move closer to the speed of light. However, time does not slow down for people who are standing still, it is just the same as always.
As people get closer to dying, they may sleep more, become drowsy or be difficult to wake. They may fall asleep while talking. A person may slowly lose consciousness in the days or hours before death.
Comatose patients do not seem to hear or respond. Speaking may not affect their clinical outcome; time spent with them takes time away from other, more "viable" patients. Comatose patients may, however, hear; many have normal brain-stem auditory evoked responses and normal physiologic responses to auditory stimuli.
This so called Atman, the Soul or the sense breaks due to sudden attack both by injury and mind due to pressure, results in coma. The broken soul in the form of Somatic cell floats along with the blood and moves throughout the body and keeps its heat.
During a coma, a person is unresponsive to their environment. The person is alive and looks like they are sleeping. However, unlike in a deep sleep, the person cannot be awakened by any stimulation, including pain.
Someone in a coma needs intensive care in hospital. They may need help with breathing. They will be fed through a tube and they will receive blood and fluids through a drip inserted into their vein.
An individual who cannot respond to any aspects of the environment, even a painful stimulus, is considered to be in the deepest coma. An individual who can open eyes to command, or attempt to speak is at the upper limit of the comatose scale. GCS scares range from 3 [the most severe] to 15 [the least severe].
Over a 30-day ICU time period, the incremental cost of persistent daily delirium or coma attributable to increased service intensity is about $18,000. This is about $600 per day, however, this cost is variable depending on the day in the ICU, with the highest costs occurring after the first week.
Hypoxic Brain Injury
In most cases, the injury is caused by a medical incident or emergency, such as a heart attack or stroke. If an individual does not receive immediate medical attention or help to restore oxygen flow, the brain suffers irreversible damage, possibly leading to death.
Brain death is not the same as coma, because someone in a coma is unconscious but still alive. Brain death occurs when a critically ill patient dies sometime after being placed on life support.
