Hypertension can be prevented by adopting a combination of healthy lifestyle habits, including:

• Eating a balanced diet rich in fruits, vegetables, whole grains, and low-fat dairy products, while reducing sodium (salt) intake and saturated fats. The DASH (Dietary Approaches to Stop Hypertension) diet is a well-recognized eating plan that helps lower blood pressure

• Engaging in regular physical exercise, such as aerobic activities (walking, running, cycling, swimming) and resistance training. Exercise helps maintain a healthy weight and directly lowers blood pressure

• Maintaining a healthy body weight, as overweight and obesity increase the risk of developing hypertension

Together, these measures-balanced diet, regular exercise, and healthy weight- are effective in preventing hypertension
