Noisy environments can significantly and negatively effect our bodies, and are a great villain to concentration, learning, and productivity in classrooms and offices. Headaches are one momentary symptom of noise. But staying exposed to very noisy places can bring greater problems such as hearing loss, lower concentration, high blood pressure, and even poor digestion. It can also trigger high levels of stress, sleep disturbances, mood changes, increased heart rate, and ringing in the ears. This is an invisible enemy and is often neglected in big cities with the noise of heavy traffic, demolition. and noisy equipment, such as generators and air conditioners. However, effective measures can be taken to avoid this unnecessary noise. #noisy#environments#headaches#lowerconcentration#highbloodpressure#cities#heavytraffic#airconditioners#exposed#invisibleenemy#generators#effective
