Among the environmental factors, a diet high in sodium and low in potassium can increase the risk of hypertension. Environmental factors associated with the development of hypertension also include chronic mental stress, smoking, and weight gain. Maintaining a good lifestyle, such as eating a light diet, reducing sodium and fat intake, eating more vegetables and fruits, controlling weight, increasing exercise, maintaining a good state of mind, avoiding mood swings, not being fatigued and staying up late, quitting smoking, limiting alcohol, and ensuring a reasonable amount of sleep, are all important in preventing the development of hypertension. For patients who have already developed hypertension, it is important to control blood pressure for a long time through active lifestyle regulation and the selection of reasonable antihypertensive drugs.
