Along with individual lifestyle factors like psychology, sports, diet, et cetera, human health and longevity are directly influenced by the local environment and dietary nutrition. Environmental factors include climate (temperature, precipitation, humidity, etc.), and chemical and physical contaminants of the air, soil and water. Nutritional factors include major and trace dietary elements, vitamins, unsaturated fatty acids, and so forth. In the elderly, extreme temperatures have a significant impact on mortality [1,2,3,4,5,6], and exposure, or lack of exposure, to the climatic change often prompts long-term effects of harsh winters can contribute to differences in mortality among these individuals [7]. Hypoxia induced by living at higher altitudes affects health and disease [8]. As for nutrition, areas with low selenium (Se) soil content exhibit endemic diseases [9,10,11]. Omega-3 fatty acids are considered anti-inflammatory, anti-thrombosis, and anti-arrhythmic. They can reduce blood lipids, relax the vasculature, and prevent cancer [12,13].
