As temperatures climb each summer, many women find themselves feeling uncomfortable outdoors. However, for women living with polycystic ovary syndrome (PCOS), hot weather can be more than just an inconvenience. Many report excessive sweating, fatigue, dizziness, and difficulty tolerating high temperatures, even when others seem unaffected. While heat intolerance is not considered an official PCOS symptom, growing evidence suggests that the hormonal and metabolic changes associated with the condition may make hot weather more challenging for some women.
