Noise pollution is an important environmental factor that has a direct impact on people’s quality of life. As well as damaging the eardrum and the acoustic nerve in your ears, it also disturbs your sleep.<\/p>\n
<\/p>\n
According to the WHO, the maximum safe exposure level is 85 decibels (dB) for a maximum of 8 hours. This is the level emitted, for example, by a fire engine siren. These 8 hours decrease if the level increases, i.e. a noise reaching 200 dB (the sound of the subway passing by, for example) can be heard safely for a maximum of 15 minutes per day.<\/p>\n
Night-time exposure, on the other hand, should not exceed 40 dB (that emitted by a normal conversation, the sound of the refrigerator or air conditioning, or a quiet pedestrian street).\u00a0 However, this level is often not met. In fact, more than 20% of the Spanish population suffers from noise problems in their homes. <\/strong><\/p>\n Furthermore, it should be noted that when you sleep, <\/strong>your body is responsible for restoring your physical and mental balance. It releases hormones that contribute to tissue growth and repair, controls your metabolism and eliminates toxins, boosts your immune system, strengthens your memory, and regulates your emotions.<\/p>\n Consequences of sleeping in a noisy environment<\/strong><\/p>\n
