High pressure of 135 and low pressure of 100 are classified as grade 1 hypertension, which does not require antihypertensive drugs for the time being, and the first consideration is to intervene in the lifestyle. Lifestyle changes include reducing body weight, increasing exercise, reducing sodium intake, increasing potassium intake, reducing fat intake, quitting smoking and limiting alcohol, and keeping a happy mood. Specific implementation details include: try to keep body mass index below 24kg/c㎡; be more active, but avoid extreme sports; consume up to 6g of sodium per person per day; eat more fresh vegetables and fruits to increase potassium intake; eat less fatty meats and more vegetables; try to quit smoking and limit alcohol consumption; and reduce mental stress and relax your mood. If blood pressure does not return to normal after the above lifestyle changes, further oral antihypertensive medication may be prescribed. The use of antihypertensive drugs should be regulated and directed by a doctor.
