In the hustle and bustle of modern society, noise is like an uninvited guest, quietly eroding our health. Although it is colorless and intangible, it has a profound and complex adverse effect on human function in the daily intrusion.
From the physiological level, noise is the first relentless impact on the auditory system. Long-term exposure to high-intensity noise environment, such as factory workshops, construction sites or areas close to major traffic routes, the hair cells of the inner ear will suffer continuous shock and damage. Once these tiny but critical hair cells are damaged, they can't regenerate, which leads to irreversible decline of hearing. At first, it may be that the perception of high-frequency sound is slow, and it gradually spreads to the daily voice frequency band, and hearing loss and tinnitus will follow, which will bring many obstacles to personal communication.
The "talons" of noise are not limited to the ears, but will launch "attacks" on other systems of the body along neural pathways. When the noise signal is introduced into the brain, it will interfere with the normal operation of the cerebral cortex and break the balance between excitement and inhibition of nerve cells. Over time, neurasthenia syndrome followed. Insomnia, dreaminess and easy waking became the normal state of sleep, while fatigue, inattention and memory loss occurred during the day. If the family works in a noisy environment for a long time, the coherence of thinking is blocked, the work efficiency drops sharply, the work error rate rises quietly, and the career development is therefore overshadowed.
The cardiovascular system is also hard to escape the noise. The stress reaction caused by noise promotes the secretion of adrenaline, norepinephrine and other hormones in the body, vasoconstriction and blood pressure increase. If you experience this physiological stress frequently, the risk of cardiovascular diseases such as hypertension and coronary heart disease will increase significantly. People living near airports or busy downtown areas often have higher incidence statistics of cardiovascular diseases than those living in quiet and livable areas.
Moreover, noise will disturb the endocrine balance of the human body. It interferes with the hormone secretion rhythm of endocrine glands such as thyroid and pituitary, and affects the normal process of metabolism. For example, thyroid function may be inhibited or over-activated, which may lead to a series of problems such as energy metabolism disorder, abnormal weight fluctuation, emotional anxiety or depression, and the whole body function will fall into a state of chaos and imbalance.
What is even more worrying is that children, as a special group, are at a critical stage of physical and mental development, and the impact of noise on them is far-reaching and incalculable. The noisy growth environment may hinder the development of language learning ability, slow vocabulary accumulation and inaccurate language expression. It is also difficult to concentrate, and it is easy to disperse when learning new knowledge, and it is difficult to improve their academic performance, which in turn affects their self-confidence and future academic trends. At the same time, the development of body organs may also be disturbed by noise, and bone growth and immune system maturity may deviate from the normal track.
In the fast-paced moment, we may have become accustomed to the surrounding noise, but it is actually a health "killer" lurking everywhere in life. Only by facing up to the harm of noise, improving the living environment, formulating strict noise control standards, and enhancing personal protection awareness, can we turn this hidden threat away, protect ourselves and the physical and mental health of our families, and return to a quiet and healthy life and work.
