Water is essential for human survival. Our bodies rely on it to function properly, and without it, life becomes challenging. While humans can survive without food for several days, living without water is much harder. So, how long can a person go without water, and what happens to the body during water deprivation?
Effects of Water Deprivation
When a person experiences dehydration, they become extremely thirsty. This lack of water can make them feel fatigued and have severe impacts on their organs. In extreme cases, dehydration can lead to death. On the first day without water, a person might feel slightly weak. By the third day, vital organs may begin to suffer, according to medical experts.
The impact of dehydration varies among individuals and depends on their endurance level. Since our bodies are made up of 70% water, many essential functions depend on it. Hence, surviving without water for an extended period is difficult.
Survival Without Water
The duration a person can survive without water varies. It could range from two days to a week. There is a concept known as the "Rule of 3s," which suggests a person can survive for:
3 minutes without air,
3 days without water,
3 weeks without food.
A study in the "Archives of Criminology" found that humans can live for about 8 to 21 days without food and water, depending on their lifestyle and environmental conditions.
Daily Water Requirements
General Recommendations:
Men should drink around 3.6 liters of water daily.
Women should drink about 2.6 liters of water daily.
This amount includes water from both liquids and food.
Factors Influencing Water Needs:
Age, physical activity, health, body size, and diet.
People who consume water-rich foods like fruits and vegetables need less additional water.
Those who eat more grains, bread, or dry foods need more water.
Environmental Factors:
The climate and environment where a person lives also affect their water needs.
It's crucial to stay hydrated to keep your body functioning well. Always ensure you drink enough water to avoid the severe consequences of dehydration.
