New research has found that short bursts of exercise may significantly improve levels of metabolites that are indicators of key physical health issues. Scientists have known for a long time that there is a link between physical activity and better health. As study say, “Regular physical activity is one of the most important things you can do for your health.”
The CDC note that regular exercise can improve a person’s brain health; help them better manage their weight; reduce their chances of developing various diseases, including diabetes, some cancers, and cardiovascular disease; strengthen their muscles and bones; and improve mental health.
While scientists are well aware of these links, they do not fully understand the precise molecular mechanisms that help explain the link between being physically active and maintaining better health.A person’s metabolism describes the chemical reactions that take place in their body. Metabolites either facilitate these reactions or are the end result of them. Scientists have identified relationships between exercise and certain changes in metabolites.
Dr. Gregory Lewis, section head of Heart Failure at Massachusetts General Hospital (MGH) and senior author of the study, says, “Much is known about the effects of exercise on cardiac, vascular, and inflammatory systems of the body, but our study provides a comprehensive look at the metabolic impact of exercise by linking specific metabolic pathways to exercise response variables and long-term health outcomes.”Cynical hostility might lead to cardiovascular diseaseIn today’s turbulent political climate, hostility is becoming an increasingly familiar part of everyday life. This negative environment not only makes it uncomfortable to socialize, but prolonged, cynical hostility may pose a serious health issue.
According to study appeared in the September 2020 issue of Psychophysiology, cynical hostility may cause an increased risk of developing cardiovascular disease.The findings resulted from data collected from 196 participants in a stress test conducted by the Laboratory for the Study of Stress, Immunity, and Disease at Carnegie Mellon University in Pittsburgh, PA.Participants took part in two lab sessions, 7 weeks apart. Sessions consisted of establishing a 20-minute baseline and a 15-minute psychological stress test.Researchers recorded each person’s heart rate and blood pressure, and the participants completed a standard psychological scale to determine their personality and temperament.
Cognitive hostility’s impact on the cardiovascular system ultimately comes down to how a person deals with repeated exposure to stress triggers.
