Stress can accelerate aging processes from "summary" of Why Zebras Don't Get Ulcers by Robert M. Sapolsky
Stress is a remarkable phenomenon that can wreak havoc on our bodies in a myriad of ways. When we encounter a stressful situation, our bodies respond by releasing a flood of stress hormones like adrenaline and cortisol. These hormones are incredibly useful in the short term, helping us to fight or flee from immediate danger. However, when stress becomes chronic, these hormones can start to cause serious damage. One of the most insidious effects of chronic stress is its ability to accelerate the aging process. Our bodies are equipped with a remarkable system known as the hypothalamic-pituitary-adrenal axis, which helps to regulate our response to stress. However, when this system is constantly activated due to chronic stress, it can start to wear down our cells and tissues, leading to premature aging. At the cellular level, stress can cause a process known as oxidative damage, where free radicals wreak havoc on our DNA, proteins, and other important molecules. This can lead to a wide range of age-related diseases, such as heart disease, diabetes, and neurodegenerative disorders. Additionally, chronic stress can impair the function of our immune system, making us more vulnerable to infections and other health problems. Furthermore, stress can also affect the length of our telomeres, which are protective caps at the end of our chromosomes. Shortened telomeres have been linked to a variety of age-related conditions, including cancer and cardiovascular disease. By accelerating the shortening of telomeres, chronic stress can speed up the aging process and increase our risk of developing these diseases.- The impact of stress on our bodies goes far beyond just making us feel anxious or overwhelmed. Chronic stress can have profound effects on our cells and tissues, accelerating the aging process and increasing our risk of developing age-related diseases. It is crucial to find healthy ways to manage stress and protect our bodies from the damaging effects of chronic stress.
