The impacts and harms of noise on humans generally include hearing impairment, sleep disturbances, headaches, irritability, and elevated blood pressure.
1. Hearing impairment: Prolonged noise exposure can affect the auditory nerves, leading to symptoms such as tinnitus and hearing loss.
2. Sleep disturbance: Noise, such as car horns and renovation noise, can disrupt normal rest and study. This can easily affect rest and sleep, causing symptoms such as difficulty falling asleep and frequent awakenings.
3. Headache: Noise can irritate nerve cells in the brain, leading to neurological disorders and symptoms such as dizziness and headaches.
4. Irritability: Prolonged exposure to noisy environments can affect both mental and physical health, causing symptoms such as depression, anxiety, and irritability.
5. Elevated blood pressure: Long-term exposure to noise can trigger a stress response, increasing adrenal secretion and causing vasoconstriction. This can cause transient increases in blood pressure, and in severe cases, can develop into hypertension.
In daily life, it is recommended to keep the living environment quiet and clean, and avoid excessive noise. It is also necessary to closely monitor your own condition. If you experience any discomfort, go to a regular hospital for treatment in a timely manner.
