What is the normal range of high blood pressure?

Normal adults have high blood pressure between 90 and 140 mmHg, and low blood pressure between 60 and 90 mmHg. Therefore, high blood pressure of 110 and low blood pressure of 70 are normal, and no special medication is needed. If it is greater than or equal to 140/90 mmHg, you should consider that your blood pressure is elevated. Under normal circumstances, the following methods can be used for prevention and treatment: 1. Reduce sodium salt intake. It is currently recognized that sodium salt intake is correlated with hypertension, so the daily salt intake should be controlled and should not exceed 6g. In addition, you should be careful not to eat foods with high salt content, such as pickles and pickled meat, which can prevent hypertension to a certain extent. 2. Appropriate supplementation of potassium salt. Potassium salt and sodium salt have a certain antagonistic effect, and potassium-rich foods can be supplemented, including high-quality proteins such as milk and eggs, as well as fresh vegetables and fruits. 3. Exercise. If there are no contraindications such as serious cardiovascular disease, moderate-intensity exercise should be performed 5-7 days a week for more than 30 minutes a day, and at the same time, certain resistance exercises should be combined. 4. Control weight and avoid being overweight or even obese. 5. Quit smoking and limit alcohol. 6. If necessary, a doctor will prescribe antihypertensive drugs.
