Sila and Sleep Hygiene—Ethical Conduct as Foundation

Sila, or ethical conduct, is foundational in Buddhist practice. Dipa Ma emphasized that integrity and moral alignment directly support inner peace and stability. Modern sleep science now validates this ancient insight: guilt, remorse, and unresolved moral conflict keep the nervous system in sympathetic activation. Conversely, alignment between values and actions supports parasympathetic tone. This offers a deeper understanding of why traditional sleep hygiene—consistent schedule, cool environment, no screens—works: it is not merely mechanical but reflects respect for the body's natural rhythms and honest acknowledgment of our limits. The Buddhist understanding of sila extends this: every choice during the day—how we speak, consume media, treat others, manage reactivity—literally becomes the soil from which nighttime rest grows. Dipa Ma's life demonstrated that a person living in alignment with their deepest values sleeps deeply and wakes without the low-grade guilt that undermines restoration. This suggests that sustainable sleep improvement often requires examining not just sleep behaviors but the integrity of how we live.
