Extreme Weather Disrupts Periods: Hormonal Stress Is The Link

• Extreme weather disrupts menstrual cycles via hormonal stress pathways.
• High temperatures trigger cortisol, suppressing the HPO axis and causing irregular or delayed periods.
• Cold weather affects thyroid function, melatonin, and vitamin D, leading to cycle delays, heavier bleeding, or increased PMS.
• The body prioritizes survival over reproduction during extreme weather, leading to hormonal fluctuations and cycle irregularities.
• Mitigation strategies include limiting exposure, staying hydrated, exercising, improving sleep, and monitoring cycle changes.

Why It Matters: Extreme weather causes hormonal stress, disrupting women's menstrual cycles.
