What causes high blood pressure? I mean physically.?

What all of those risk factors you mention do is decrease the diameter, compliance or increasing the contraction of blood vessels. When you narrow the volume of the blood vessels but maintain the volume of blood, the pressure of the blood increases.

This could be a number of things First of all they are not dangerously high they are on the Normal/Higher range. Causes could be poor diet, High cholesterol etc or even what some people call " white coat syndrome " Which is where people get nervous when their blood pressure is taken and their readings will go up as a result. Im a Healthy 26 year old and run marathons and my blood pressure goes up to 150/90 when I visit the doctor but when I am in the comfort of my own home it drops to 110/60 Try taking your BP in a relaxed environment it could be all in your head :)

Emotionally stressed?

Avoid being emotionally stressed. This type of stress will temporarily increase the level of your blood pressure. High blood pressure associated with emotional stress is not long lasting and simple therapies should bring the pressure down to normal. This includes relaxation, meditation and yoga.

Having too much caffeinated drinks?

Just like stress, caffeine temporarily causes elevated blood pressure. Some people however develop tolerance to caffeine and thus high blood pressure is not sustained.

Drugs:

OCDs (over the counter drugs) and many prescriptions either cause or exacerbate high blood pressure. Take inflammation drugs like nonsteroid antinflammatory drugs for example. They have antiprostaglandin properties which contribute greatly to raising blood pressure.

Weight and Exercise:

Lack of exercise in your life is just as well life-threatening. Exercise improves blood circulation thereby helping in reducing blood pressure. Persons who do not exercise their bodies miss on this natural and easy way of maintaining normal blood pressure. Being overweight contributes to high blood pressure. Exercise and proper diet should help you loose some weight. Putting on more weight than we need to is one of the main causes of high blood pressure. So watch the waistline !

Diabetes :

diabetics are prone to high blood pressure. Having diabetes also increases the chance of developing high blood pressure because it does affect the blood vessels by hardening them, a condition referred to as atherosclerosis.

Age

Age on other hand plays a role, whereby the older you become, the less you exercise, and that is the single most likely cause of high blood pressure.

The above mentioned are just some of the many causes of high blood pressure.

Life style is often part of the issue. Life style changes now could delay or prevent you from getting diabetes later. Learn here https://tr.im/MHtYq

What you eat is not actually the cause of diabetes, but how you live can be. If you sit on the couch all day, your chances of developing diabetes goes up greatly.

Just do the best you can to not gain weight and to maintain an active life style and that will greatly help reduce some of your risks.

i think smoking lower's blood pressure. Anything that causes the heart to beat faster will raise blood pressure, running, sex, etc

Diet and stress.Some people have high blood pressure that is inherited.
