Physiological and Cultural Adaptations to High Solar Radiation.
I chose the environmental stress of “high levels of solar radiation” and its effects on those living in conditions of extreme exposure. Geographic locations affected by extreme solar radiation aren't necessarily limited to warm climates . Although extremely hot environments can be a sign of high solar radiation levels, high altitudes and atmospheric conditions with less cloud coverage, as well as constant exposure to the sun, can also be factors . The negative effects of living in these environments consist of electrolyte and water imbalances, which cause heat stroke and dehydration, leading to low levels of energy and, in more extreme cases, death. Organ functionality can be negatively impacted , as organs such as the heart and brain may fail to receive enough oxygen carried through the bloodstream due to the overexertion of energy used to cool the body and conserve water. Vitamin B9 (folate) can also be broken down in the bloodstream, which slows the building of red blood cell...
