Summary
Hair cortisol concentration (HCC) offers a promising non-invasive method to track stress hormone levels over time, particularly during pregnancy. Cortisol, crucial in the body’s stress response, is deposited into hair, reflecting past hormone levels. A study led by Dr. Lucy King at Stanford University examined HCC dynamics in pregnant women and postpartum, finding significant increases in cortisol during pregnancy and decreases after childbirth. The study also explored the link between cortisol levels and depressive symptoms, revealing no significant correlation. However, small but significant associations were found between psychosocial stressors and cortisol levels. This method’s ease of use and potential for large-scale application could provide valuable insights into maternal health and stress-related conditions.
