During the day, over 40 million Italians—about 72 percent of the population—are exposed to excessively high noise levels, according to the Italian Ministry of the Environment. Among the possible ill effects of prolonged exposure to such noise are accelerated heartbeat, variations in arterial pressure and respiratory capacity, gastritis, and nausea, reports Corriere della Sera. In big cities the noise from traffic interferes with normal sleep. Urban nighttime noise levels can exceed 70 decibels, increasing the risk of a reduction in deep sleep and dreaming. Says Lucia Venturi, scientific director of the Italian environmental association Legambiente: ‘It is estimated that each of the 18 million people who live in large urban areas loses 30 minutes of sleep every night. This would amount to 22 sleepless nights per person each year.’
