Air pollution is one of the hidden health killers. With the continuous development of urbanization, the pollution sources such as industry and automobile exhaust are increasing, which leads to the gradual decline of urban air quality and poses a great threat to people's health. With the passage of time, people exposed to polluted environment for a long time are prone to respiratory diseases, cardiovascular diseases and other diseases.
Good living habits are also an important factor to keep healthy. Smoking, drinking, eating junk food and other bad habits will affect physical function and health. In addition, long-term work stress and mental stress will also have a negative impact on physical health. We should try to live a healthy lifestyle, such as proper exercise, no smoking, no drinking, and keep regular living habits to fight against potential invisible killers.
