Formaldehyde may induce high blood pressure or hypertension in patients, and environmental factors have an effect on blood pressure itself. In addition to the environment, there are genetic factors and the patient’s daily lifestyle, all of which may directly affect the patient’s blood pressure level. For example, patients who have been in a polluted environment for a long time, always have a high salt diet, high fat diet, and smoke and drink heavily. The probability of hypertension in such people is much higher, which is exactly why for patients with initial hypertension, the first step is to carry out 1-3 months of lifestyle intervention to improve it, because lifestyle itself is closely related to hypertension. It is recommended that people with hypertension must pay attention to a low-salt, low-fat diet, exercise to lose weight, and keep their mood happy, in order to keep their blood pressure under better control.
