The detrimental effects that stress may have on both the human body and psyche have been demonstrated by yet another study.
Continuous stress can raise the likelihood of developing lethal cancer, according to a study by a team of researchers from the Medical College of Georgia published in the journal SSM Population Health.
The hormone cortisol is released by the body when it is under stress. When a stressful situation is ended, cortisol levels typically decline. On the other hand, “ongoing psychosocial stressors” result in chronic or persistent stress, which means that the levels of cortisol never decrease.
Therefore, the hormone has the potential to seriously injure the body, according to epidemiologist Dr. Justin Xavier Moore in a press statement.
Moore and his team examined these harmful outcomes on more than 41,000 individuals, using information from the National Health and Nutrition Examination Survey (NHANES), which covers years 1988 to 2019.
The participant’s body mass index, systolic and diastolic blood pressure, total cholesterol, and haemoglobin are just a few of the measurements that are recorded in the database.
They selected individuals who had died of cancer and compared this data to information from the National Death Index.
The team discovered that those with higher stress loads were 2.4 times more likely to die from cancer than those with lower stress loads.
According to Moore, if two 20-year-old acquaintances were compared, the one with higher allostatic load—defined as “the cumulative burden of chronic stress and life events”—was more likely to get cancer.
