Mountain sickness is a condition that is characterized by a lowering of oxygen levels in the body because of the weaker oxygen content in the atmosphere. This results in people becoming fatigued and less on the take. For many US soldiers, this carries an inherent danger during their missions.
For example half of the nation of Afghanistan is located at heights well over 10,000ft. During their stay some US soldiers have reported feeling the strains of fatigue as they go about their military activities. This is hardly a welcomed development. And so when researchers at Stanford got together to check the viability of the adoption of Viagra as a drug which could be used at high altitudes, they had an adoption of the drug by the military amongst their intended aim. Viagra (comprising of the causative compound Sildenafil citrate) works by triggering the relaxation of body muscles. Amongst those affected are numerous blood vessels. As these blood vessels relax, they allow an improved flow of blood to the various organs that need them. In the case of erectile dysfunction, this is revealed to be the male organ.
Viagra has already been found to be extremely useful in the treatment of conditions like pulmonary hypertension. It has also witnessed wide adoption amongst athletes because of its ability to boost oxygen delivery levels to the body. For example, during the course of the research 10 cyclist were made to go through different routes with varying amounts of Viagra in their system. It was discovered that some of the athletes were able to improve their finishing time by as much as 15%. Such results bodes well for its eventual adoption amongst users,
