Longevity in Persistent Vegetative States
A persistent vegetative state can last for an extended period of time, with individuals often surviving for approximately 10 to 14 days even after artificial sustenance is withdrawn. In this comatose state, the calorie intake of these individuals is minimal. In contrast, those who are healthy and leading an active lifestyle burn calories at a much faster rate, which ultimately reduces their ability to survive without food.
The Impact of Hydration on Survival Duration
Hydrating oneself can have a significant effect on how long a person can survive without food. According to a well-known study, it is commonly believed that a person can only go without food or fluids for a maximum of 21 days. However, this survival duration can be extended up to two months if an individual has access to a source of fluids. Experts assert that consuming a minimum of six cups of water per day is crucial for enduring periods of starvation.
