An encyclopedia of holistic health — seven healing traditions and modern science, side by side, with an evidence level on every claim.
AyurvedaScientists have spent two decades tracking millions of sleepers, and the finding that keeps surprising them isn't about too little sleep. It's about too much, and about something even more basic than hours: whether you go to bed at the same time at all.

Therapies
Women's HealthThe classical Charaka Samhita lists "pleasant sound" among a long chain of remedies for lost sleep, alongside oil massage, warm baths, rice with curd, milk, wine, a cheerful mind, pleasant scents, and a comfortable bed. Sound here is one ingredient in a broad lifestyle prescription, not a standalone cure. Notably, the other great classical text, the Sushruta Samhita, never once connects music to sleep. It treats a love of music as a personality trait of certain constitutions, and in places even lists music among behaviors to avoid, showing real disagreement within the tradition itself.
What the science saysModern evidence supports pleasant sound as one piece of a broader sleep routine, matching Charaka's framing as one remedy among many rather than a dedicated sleep therapy.
