British researchers compared stress levels and body weight of more than 2,500 men and women over the age of 54 years who participated in the English Longitudinal Study of Ageing. The research looked at the level of the stress hormone called cortisol in the hair gathered from the participants.
Those results proved that chronic stress associated with a higher risk of obesity. Cortisol is a hormone produced by the adrenal gland that are released into the bloodstream during stress. In addition to suppress inflammation and regulates blood pressure, it helps to keep up supply stabilizes blood sugar and gives a boost of energy to handle emergencies on the body.
Cortisol stream of glucose to the brain, keeping things that happens during stress and plays a major role in metabolism, body composition, and body fat accumulation. The release of cortisol triggered by a receptor located in the dense network of visceral fat – the kind of fat that surrounds the organs – which could explain weight and weight loss correlation.
Cortisol normally tested through blood, urine, or saliva. Cortisol levels fluctuate throughout the day depending on what you eat, stressful situations, and disease. That is why clinical trials on blood, urine, and saliva can show the size are not good for long-term stress.
Stress and obesity
Research has shown that cortisol levels can also be detected in hair follicles. The results showed that chronic exposure to high levels of cortisol may contribute to obesity. However, the researchers could not establish cause and effect that correct.
High cortisol in hair may simply reflect social or biological stress associated with obesity. For example, the social stigma that people with obesity often suffer so can cause stress and high cortisol levels.
Researchers continue to measure study participants every four years to determine, how stress affects the body mass over time. People who experience chronic stress can figure out a way to relieve tension such as meditation or yoga. There is plenty of evidence, cortisol influence appetite and enjoyment choice of high-calorie foods.
