The main causes of high blood pressure or hypertension are as follows:

Main causes of high blood pressure
Dietary habits:

Excessive salt intake: Excessive salt (sodium) in food causes water retention in the body and increases blood pressure.

Lifestyle:

 

Lack of exercise: People who do not exercise enough are more likely to have high blood pressure.

Obesity: When you gain weight, the heart has to work harder to pump blood, which increases pressure.

Stress:
Continuous mental stress increases BP by increasing heart rate and narrowing blood vessels.

Unhealthy habits:

Alcohol and smoking harm blood vessels and increase blood pressure.

Genetics:
If your parents or close relatives have high blood pressure in your family, you are more likely to have it.

Age and other diseases:
As we age, the elasticity of blood vessels can increase. Similarly, diabetes and kidney diseases can also increase BP.

 

Things to keep in mind to control BP:
Reduce salt: Reduce the amount of salt in your diet as much as possible.

Exercise: Practice brisk walking for at least 30 minutes every day.

Food: Include vegetables, fruits, and nuts in your diet.

Rest: Practice regular sleep and meditation to reduce mental stress.
