Lunaception

Discover Natural Cycle Regulation with Lunaception

Lunaception helps you regulate your menstrual cycle naturally using the scientifically-backed Lunaception method developed by Louise Lacey in 1975. By controlling your light exposure during sleep, you can work toward a more regular cycle without hormones or medications.

How It Works

The Lunaception method is simple: sleep in complete darkness most nights, and use a dim nightlight during your ovulation window (days 14-16 of your cycle). This mimics the natural light patterns humans experienced before artificial lighting, potentially helping to restore hormonal balance and cycle regularity.

The Science

Before electric lighting, women living together often experienced synchronized menstrual cycles that aligned with the moon's phases. Research suggests that light exposure plays a crucial role in regulating reproductive hormones. The Lunaception method recreates the light conditions that may have caused this natural synchronization.

Getting Started

Simply input your last period start date and cycle length during setup, and Lunaception will guide you through the daily light protocol. Track your adherence and
