“The preclinical studies suggesting that quercetin can suppress oxidative stress, reduce the inflammatory response, and decrease atherosclerotic lesions have been challenging to replicate in humans — possibly due to small, non-standardized trials using different amounts and sources of quercetin.”

“Although iron is essential for many physiological processes in the body, it can also be harmful, inducing oxidative stress and hindering neurogenesis. The body typically stores iron in protein complexes until needed, but these storage processes decline with age, leading to iron accumulation in body tissues.”

“Emotional context may influence airway disease, while chronic inflammatory disease may affect the brain in return. Whether training stress-sensitive brain circuits can change asthma's long-term course—or protect brain health—remains an important unanswered question.”

“Exposure to air pollution promotes oxidative stress and increases the risk of developing many chronic diseases, including cardiovascular disease, cancer, hypertension, and diabetes, markedly shortening people's lives.”

“Light also reaches the stress-response system Cortisol is not simply a stress hormone to be driven down. Its normal morning rise helps support wakefulness, while persistently elevated or mistimed cortisol can reflect disruption of the circadian and stress-response systems.”

“In a study in which old mice, 26 to 28 months of age, were administered 300 mg/kg/bw of nicotinamide mononucleotide in their diet for 8 weeks, age‐associated arterial dysfunction and oxidative stress were reversed and arterial SIRT1 activity was increased.”

“Mice that ate on a time-restricted schedule had fewer active genes involved in inflammation and oxidative stress and more active genes involved in metabolism and autophagy – a cellular defense mechanism.”

“These findings suggest that air pollution contributes to the development of eczema. Given that PM2.5 can infiltrate the skin and contribute to skin barrier dysfunction, oxidative stress, and inflammation, addressing air pollution could be a key strategy for preventing and managing eczema.”

“The plastics detected included polyethylene, polypropylene, and PET, the same materials in everyday items like bags and bottles. These microplastics can cause inflammation and oxidative stress, leading to respiratory problems such as asthma and COPD.”

“Plastics may be a hidden contributor to heart disease: chemical additives that disrupt hormone function and damage blood vessels. Evidence indicates that di-2-ethylhexylphthalate (DEHP)—a phthalate used to soften plastics—drives oxidative stress, metabolic dysfunction, and cardiovascular disease.”
