The sun
Helios, the sun, is a deity who fascinates, conquers, bewitches, renews, gives power, but also capable of annihilating and incinerating his worshipers. Overcome the miseries of men and lead science to copy its secrets. It is the natural clock of every living thing in the universe, a constant cycle of life and death. Nature follows its rhythm as a faithful servant of its will. Many peoples have adored him attributing immeasurable powers to him. Civilizations, which arose in his name like Magna Graecia, got lost in the paths of history leaving dust burned by his darts. The binomial light-darkness is the deity worshiped by all beings.
Sunstroke
We are in summer, under the reign of the sun, and we are forced to reckon with its donations and complications: sunstroke. Sunstroke is a consequence of excessive exposure to the sun's rays and manifests itself with a general and sudden malaise, followed by headache, feeling of vertigo, nausea and scant sweating. The body temperature rises, the skin becomes dry and red. The determining cause is the action of the sun's rays and infrared and ultraviolet radiation on the head. It differs from heat stroke in the triggering cause.
Heat stroke
Heatstroke is caused by very high temperatures, associated with high humidity and lack of ventilation. The body is equipped with a complex system of thermoregulation, capable of adapting it to environmental temperatures. Acclimatization times range from a few days to a few weeks. In the event that there is no possibility of acclimatization due to high external temperatures, reduced ventilation and high relative humidity, the body is unable to disperse heat through sweating and is subject to heat stroke. Heat exhaustion, resulting from heat stroke, occurs from dehydration with excessive loss of water and salts. Most exposed are children and the elderly.
Evolution of sunstroke
Sunstroke or hyperthermia produces heat stress or heat exhaustion with confusion, muscle cramps, nausea with vomiting, and profuse sweating to disperse body heat. Sweating removes heat from the body by moving it to the skin surface and cooling it with evaporation, an endothermic process. The loss of water, resulting from sweating, if not compensated by the introduction of water, leads to dehydration. You stop sweating and your body temperature rises rapidly. Without interrupting exposure to the sun, the body temperature reaches 39-40°C and the real pathology of sunstroke begins. Above 40°C you risk your life, at 41°C the brain mass suffers serious damage starting the process of death, with the epilogue at 45°C. At 50°C there is muscle stiffness and immediate death.
Consequences of sunstroke
Sunstroke causes loss of lucidity, makes rescuers hostile and produces headaches. Dehydration reduces blood pressure and leads to mental confusion or fainting, making it impossible to stand upright. The skin becomes red due to dilated capillaries. The skin of the face takes on a bluish color due to the outflow of blood in a centripetal direction with chills and goosebumps, as in high fever. The very high temperature blocks the functioning of the internal organs causing an irreversible coma. Children exposed to the sun can suffer from convulsions. The elderly are easy prey to sudden sunstrokes with unfortunate consequences according to the degree and time of exposure to the sun.
