Noise is any unwanted sound that bothers us. That sound can be very loud, painful, but also inaudible.
Today there is more and more noise. Usually with noise we focus on sounds that are very loud, which makes us irritable, angry, helpless, heart rate increases, blood pressure rises, breathing speeds up, sweating increases, or sudden muscle contractions occur, and after prolonged exposure to depression, damage hearing, reduced ability to work, fatigue, poor communication, concentration problems, dysfunction of the digestive organs, especially the intestines and the functions of the endocrine glands (which produce hormones; pituitary gland, adrenal gland...). Rest and sleep are best for regenerating the body from noise.
