Biological and Lifestyle Factors Contributing to Women's Longer Lifespans Than Men
Summary
Women typically live longer than men worldwide due to stronger immune systems, protective hormones like estrogen, genetic advantages from two X chromosomes, and healthier lifestyle choices that reduce risk-taking behaviors.
Key Points
- Women have stronger immune systems than men, helping them fight infections and diseases more effectively.
- The hormone estrogen in women protects the heart and blood vessels, lowering the risk of heart disease and stroke.
- Women possess two X chromosomes, providing genetic protection by compensating for defective genes.
- Men tend to engage in riskier behaviors such as smoking and drinking, contributing to higher mortality rates compared to women.
