Research supported by the National Institutes of Health (NIH) has examined environmental noise as a factor influencing sleep quality, stress physiology, and cardiovascular health.

NIH-funded studies indicate that noise exposure, particularly during nighttime hours, can disrupt sleep and contribute to physiological stress responses even in the absence of conscious awakening.

This body of research supports the understanding that repeated sleep disruption and chronic stress activation are key pathways linking long-term noise exposure to increased risks of hypertension and cardiovascular disease.
