There have been cases where people have died due to fatigue and dehydration leading to heart failure. In 2010, US swimmer Fran Crippen died due to this factor. The air temperature was very high that day and on top of the heat, the temperature of the water was very high too. Severe fatigue led to his death as per the reports, but, the root cause of this fatgue was the heat (Fantz, 2010).
The couple had very high alcohol content in their blood and was quite drunk at the time of their death. Wine causes a huge amount of dehydration (Gordis, 2008). If not treated, there may be delirium, unconsciousness and, in extreme cases, death. Symptoms of dehydration are noticeable after losing just 2 percent of the volume of water. Initially thirst and discomfort appear, possibly accompanied by loss of appetite and dry skin. Athletes may suffer a loss that increases problems by 30 percent. It leads to loss of strength, increased heart rate, increased body temperature, and fatigue. Symptoms become increasingly severe with greater water loss. Heart rate and respiratory rate begin to rise the decline in the volume of blood plasma and blood pressure to offset. In turn, the body temperature may increase due to decreased sweating. Having lost about 5 or 6 percent water, an individual can get sleepy, may have headaches, nausea and tingling in the limbs. If a person loses 10 to 15 percent of body water, the muscles become spastic, skin becomes dry and wrinkle, vision becomes cloudy, urine volume is considerably reduced. Over 15 percent loss is usually fatal (Sarda, 2008).
