High blood pressure can be caused by various things such as being over weight and smoking. High blood pressure is common in older people too. Best to prevent high blood pressure would be to maintain a healthy diet, exercise regularly, and live a healthy life.
First off, you should eat a balanced diet. Exercise. You dont have to run every single day, but you need to move around regularly. Meaning, you shouldn't stay in one place for too long. Limit your Alcohol consumption Eat a lot of fruit and veges, because they have a lot of vitamins. You hsould cut back on the sodium hydroxide (salt or NaOH). These are a few examples. I hope this helped :)
