How does space radiation affect human biological health?
Answer
By damaging DNA and potentially increasing the risk of cancer
Exposure to ionizing radiation in space presents severe risks to human physiology. When high-energy particles collide with the body, they can cause direct damage to cellular DNA, which is a precursor to long-term health issues like cancer. Furthermore, emerging research indicates that this environment can compromise the immune system and negatively impact cardiovascular health. These biological risks are exacerbated by the interplay between radiation and other stressors of spaceflight, such as microgravity, which together can profoundly affect long-term astronaut health.
