Abstract
Stress is an unavoidable part of human life that affects a majority of people: In 2018, 55% of Americans reported experiencing stress (Gallup Global Emotions, 2019). Various factors contribute to the emergence of nervous stress among individuals, including environmental, physical, and psychological stimuli. Physical and psychological issues arise as a result of stress, which is the subject of our research study, giving it significant practical value. Here, we have tested the possible correlation between increase in oxidation species and severe psychological issues at a community level. To understand any possible connections between these two parameters, tests were conducted on 200 rats that were divided into three general groups based on the duration of stress exposure. Each group was further divided into five smaller groups with 10-20 rats. Treatments were setup with or without vitamin E with periods of stress immobilization. Samples were then collected to conduct necessary analyses from control, experimental, and treatment groups. Immobilization stress types, i.e., acute and chronic stress, caused noticeably different physiological changes, especially with respect to nature and severity of response. Chronic stress induced different responses depending on the exposure period as well. Furthermore, vitamin E appeared to have a protective role due to its antioxidant nature, which highlights the need for investigations on oxidative stress-related disease treatment and prevention.
