Altitude Sickness And Dehydration
What is Dehydration?
Well, many people confuse the symptoms of dehydration with altitude sickness, but at minimally to moderately high altitudes, dehydration is responsible for more illness than oxygen insufficiency. Every day you lose water through your breath, perspiration, urine and bowel movements. For your body to function properly, you must replenish its water supply by consuming beverages and foods that contain water. Lack of water can lead to dehydration, a condition that occurs when you don't have enough water in your body to carry out normal functions. Even mild dehydration can drain your energy and make you tired. So you should drink roughly 3 liters (about 13 cups) for men a day & 2.2 liters (about 9 cups) for women a day. Symptoms of dehydration usually begin with thirst and progress to more alarming manifestations as the need for water becomes direr. The initial signs and symptoms of mild dehydration in adults appear when the body has lost about 2% of its total fluid. These mild dehydration symptoms are often:
* Dry, sticky mouth
* Sleepiness or tiredness
* Decreased urine output
* Few or no tears when crying
* Dry skin
* Dizziness or lightheadedness
Why should you drink more water at high altitudes?
The atmospheric conditions at higher altitudes will alter the rate of water loss from the body, causing you to lose more. You will need to drink extra water to provide your body with enough fluids to function properly at high altitudes.
What is Altitude Sickness?
Altitude sickness is a pathological effect of high altitude on humans, caused by acute exposure to low partial pressure of oxygen at high altitude. It commonly occurs above 2,400 meters (8,000 feet). It is hard to determine who will be affected by altitude sickness, as there are no specific factors that correlate with a...
