Would it be beneficial to human health to fly at lower altitudes?
If planes routinely flew lower than they do, there would be significant impacts on both aviation and public health. In terms of aviation, flying at lower altitudes would result in more air resistance and increased fuel consumption, leading to higher costs and potentially longer travel times.
However, from a public health perspective, flying at lower altitudes would have several benefits. One significant advantage would be the reduction in exposure to ionizing radiation from the Earth's radiation belt. At higher altitudes, such as those typically flown by commercial airliners, passengers and crew are exposed to greater levels of ionizing radiation, which can increase the risk of cancer and other health problems. By flying at lower altitudes, the exposure to ionizing radiation would be reduced, potentially lowering the incidence of cancer and other related diseases.
Additionally, flying at lower altitudes could also lead to a reduction in the incidence of heart disease. It has been suggested that exposure to high altitudes for prolonged periods can contribute to the development of cardiovascular disease, due to the reduced oxygen levels at high altitudes. Flying at lower altitudes could mitigate this risk, potentially leading to improved cardiovascular health for passengers and crew alike.
Overall, while there would be some operational challenges associated with flying at lower altitudes, the potential health benefits make it an intriguing area of study for both aviation and public health professionals.
