1. Prolonged exposure to noise pollution increases the risk of heart disease. Constant background noise levels as loud as a garbage disposal unit, traffic noise from a major road and other noises higher than 60 decibels can cause cardiovascular effects, such as high blood pressure, faster pulse rates, elevated cholesterol, irregular heart rate and heart attacks. People living with noise pollution are more likely to take cardiovascular medication

2. Sleep disturbance due to noise pollution affects people's health and mood. Poor sleep is bad for heart health, and causes tiredness, depressed moods and poor performance at many tasks, as well as reduced reaction times. When indoor noise levels are reduced, rapid eye movement (REM) sleep and deeper, slow wave sleep can increase. Greater levels of noise pollution increase in the number of night awakenings and changes between sleep stages. 
3.Noise pollution causes a range of psychological effects. In people vulnerable to mental illnesses, noise pollution can increase the development and symptoms of disorders. It can also contribute to nervousness, anxiety and neurosis, and emotional instability, moodiness and argumentativeness, causing social conflicts.
