Sleep hygiene refers to the collection of habits, routines, and environmental conditions that support consistent, restorative sleep. From the timing of your last meal to the temperature of your room and the light you’re exposed to before bed, small daily choices compound into the quality of rest your body receives each night. Prioritizing sleep hygiene is one of the most foundational things you can do for your overall well-being, touching everything from stress management to hormone balance and immune function.
Quality sleep is when the body does its deepest repair work, consolidating memory, regulating mood, and supporting cellular regeneration. Most adults thrive with seven to nine hours of uninterrupted sleep, yet modern life often works against this natural need. Building a consistent wind-down ritual, limiting screen exposure in the evening, and creating a cool, dark sleeping environment are simple but powerful ways to signal to your body that it is time to rest and recover.
