A Long Walk To Water Reasearch

After 3 days, you need water or you will perish. Some people have survived 8 to 10 days without water. As 65% of the human body, water is essential to people. Water flows through the blood , carrying oxygen and nutrients to cells and flushing wastes out of our bodies.

How Does Dehydration Affect the Body?

Dehydrated women experienced a significant drop-off in energy and mood. Basically, they felt tired and lousy about life. Also, women were more likely to have headaches and report difficulty concentrating. The brain is extremely sensitive to even small changes in the amounts of ions like sodium and potassium found in your body’s fluids. No one can pinpoint exactly why your brain flips out when it becomes dehydrated. The mood and energy changes may be some sort of built-in alarm system, there to let you know you need water. (Men experienced some of these effects, but not to the same extent as women. People say that probably has to do with body composition differences.)

Dehydration is not a simple health issue. Anyone can run out of liquids in their body due to various reasons, so it is important that you always hydrate yourself with water.If your body has lost one to two percent of its entire water content, you will feel thirsty, a sign that you need to replenish the lost liquids.

Dehydration happens when you've lost a lot of water in your body without replacing it, stopping your body to perform its normal functions. Mild dehydration can easily be treated but if it reaches high levels, it can be life-threatening and will require immediate medical attention.

What are the symptoms of Cholera?

Symptoms of cholera can begin as soon as a few hours or as long as five days after infection. Often, symptoms are mild. But sometimes they are very serious. About one in 20 people infected have severe watery diarrhea accompanied by vomiting, which can quickly lead to dehydration. Although many infected people may have minimal or no symptoms, they can still contribute to spread of the infection.

How wide-spread is this disease?

It is not common in the U.S. because of our sewage systems and filters. However, in other countries like Southern Sudan, they don't have a sewage system and filters so it is common in that area.

How is it treated?

Rehydration therapy, which means restoration of lost fluids and salts through rehydration therapy which is the primary goal of treatment.

Antibiotic treatment, which reduces fluid requirements and duration of illness, it is indicated for severe cases of cholera.

Zinc treatment has also helps to improve cholera symptoms in children.

How Deadly is it?

Cholera can be deadly within hours. Cholera is a bacterial illness that causes severe diarrhea and dehydration and can be lethal within hours if a person is not treated. This is a bacteria that actually is in the environment. It's in brackish water in the river.

How can it be avoided?

Drink only water that you already have boiled or treated with chlorine or iodine. Other safe beverages include tea and coffee made with boiled water and carbonated, and bottled beverages with no ice. Eat only foods that have been thoroughly cooked and are still hot, or fruit that you have peeled yourself. Avoid undercooked or raw seafood like fish and crawfish. Make sure all vegetables are cooked -- avoid salads. Avoid foods and beverages from street vendors, and do not bring perishable seafood back to the United States.
