Women’s Health is a dynamic, lifelong journey that spans the very personal experiences of menstruation to the broader goals of longevity and vitality, inviting readers to see their bodies as continuously evolving systems that respond to choices, environments, and culture with measurable shifts in energy, mood, resilience, and function across the decades, while also recognizing the social and historical factors that influence access to care, education, and empowerment.Framing menstruation as an informative signal rather than a nuisance enables more effective attention to sleep quality, nutrition, stress, physical activity, and medical care, so that menstrual health can be leveraged to optimize daily performance, recovery, and long-term wellbeing while dismantling stigma and promoting proactive conversations with clinicians and loved ones.
