The things that used to roll off you don't anymore. You are not weaker. Your stress regulation system has been neurobiologically reconfigured by perimenopause. The Swiss Perimenopause Study confirms cortisol rises during the transition — at the exact moment the sex hormones that buffer and modulate it decline. The HPA axis fires at lower thresholds.

From the eating window shift that changed my sleep in week one, to the supplements backed by real clinical research, this is the honest, experience-led guide I wish I'd found first.
