Why Menopause Steals Your Sleep, and What Actually Helps

Ayurveda

Ayurveda never names menopause as a disease. Sushruta's Sutrasthana simply records that menstrual flow "commences at the age of twelve and ceases at fifty," tying its end to the body's natural aging rather than illness. Insomnia is treated as its own well-developed topic elsewhere in the same texts, listed among the eighty classical disorders of Vata (one of the three governing bodily forces) and also linked to aggravated Pitta, the tradition's heat-related force. Notably, classical treatment for lost sleep involved no herbs at all: oil massage, bathing, nourishing food, calming sound and scent, and keeping a steady bedtime. No surviving Ayurvedic source, however, directly connects the end of menstruation to sleeplessness. That bridge is one we're drawing today, not one the classics drew themselves.

What the science saysModern research confirms sleep disruption rises around the menopausal transition, but this is a connection the classical texts never explicitly made themselves.
