Environmental health care: a quiet living and working environment is most closely related to the health care of the heart. Noise has the most obvious influence on the auditory system and cardiovascular system. If you suddenly hear a strong voice, your heart will speed up, your jumping strength will be strengthened, and you will be flustered. Long-term noise stimulation will not only damage the auditory system, but also damage the cardiovascular system. If you live or work in a noisy environment for a long time, the incidence of cardiovascular disease and hypertension will increase obviously, and you will be emotional and impatient, so you should choose a quiet place to live and work. If the noise in the environment is large (above 60 decibels), we should actively take some necessary measures to reduce the noise intensity. If the noise around the living environment is large, the relevant departments should be required to solve the noise source problem and reduce the noise intensity; Or install double glazing to reduce noise. The audio, TV and other electrical appliances in the room are prone to noise. When using them, the volume should be low so as not to affect yourself and others. You can also go to an empty and quiet place to exercise or avoid noise interference.
