Noise affects health

Noise is often seen as an annoyance, but it is also a serious public health hazard with effects beyond hearing loss.

Chronic exposure to loud sounds can increase stress levels by activating the body’s autonomic nervous system and endocrine system, which control heart rate, blood pressure, and other physiological processes.

It can also disrupt sleep, even if a person does not fully wake up, triggering stress responses that accumulate over time.

Long-term exposure to traffic noise, for example, has been linked to hypertension (high blood pressure), coronary artery disease, stroke, and Type 2 diabetes.

These risks are not limited to workplaces; everyday environments like crowded restaurants, public transportation, or fitness classes can contribute to harmful noise exposure.

The World Health Organization (WHO) provides environmental noise guidelines that recommend lower noise levels than workplace standards because they account for longer exposure periods and broader health impacts.
