Hair strands contain valuable information about senior citizens’ stress levels that can be used to determine an individual’s cardiovascular disease risk, according to a recent study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM). Unlike a blood test that captures a snapshot of stress hormone levels at a single point in time, a scalp hair analysis can be used to view trends in levels of the stress hormone cortisol over the course of several months. This approach allows researchers to have a better sense of the variability in cortisol levels. The study found seniors who had higher long-term levels of the stress hormone cortisol were more likely to have cardiovascular disease.
