Stress and PCOS are closely linked through cortisol, which can worsen insulin resistance and increase androgen production. This chapter explains that connection and the approaches that may help. It covers Mindfulness-Based Stress Reduction, Cognitive Behavioural Therapy (CBT) and Acceptance and Commitment Therapy (ACT), describing what each involves and how it can support emotional wellbeing. Sleep is discussed as a key factor, since poor rest raises cortisol. The chapter also mentions herbs such as chamomile, ginseng and ashwagandha that may support the body's stress response, and encourages tailoring these tools to your own lifestyle.
