According to Dr Manisha Rao, consultant endocrinologist and women’s health specialist, winters should be packed with mindful healthcare for women with PCOS to prevent symptoms from escalating.

What actually happens in winter

During winter, physical inactivity increases which can worsen insulin resistance one of the major contributors to PCOS. Comfort eating also becomes common, often leading to weight gain and fluctuations in blood sugar levels.

Reduced exposure to sunlight lowers vitamin D levels which has been linked to PCOS and can further disrupt menstrual cycles. Less sunlight also affects serotonin, the feel-good neurotransmitter, contributing to low mood and mental fatigue.

Additionally, higher levels of cortisol the stress hormone, during colder months can interfere with reproductive hormones, lower temperatures also slow down metabolism, making calorie regulation harder and potentially increasing androgen levels which further adds on to the PCOS symptoms.

Steps to manage PCOS during winter
