Getting your daily coffee fix may seem necessary to help you
wake up in the morning, but does caffeine raise blood pressure? Is caffeine
consumption safe for those who have already been diagnosed with hypertension?
Here's what all men and women should know about how caffeine may affect your
Increase Blood Pressure Levels?
Caffeine intake can cause raised blood pressure in some
individuals. Your beginning blood pressure level plays a role in how much of an
increase you will experience. Individuals who have normal blood pressure may
only experience a temporary increase in blood pressure, according to Health
Services at Columbia University. The increase tends to be more significant for
those who have already been diagnosed with high blood pressure, however.
Does caffeine raise blood pressure more drastically if you
consume it frequently? Actually, while research has found that your tolerance
of caffeine does play a role in how much your blood pressure will be affected
by consumption, the opposite seems to be true. A Harvard study found that
people who drank coffee for several weeks experienced a smaller increase in
their levels than those who were not used to drinking coffee.
Keep in mind that while caffeine consumption can raise your
blood pressure levels, it is not considered a cause of hypertension, according
to Health Services at Columbia University. If you have normal blood pressure
levels, you will generally not need to worry about cutting out caffeine.
If you have already been diagnosed with high blood pressure
and are concerned about the effects that caffeine may have on your levels, it
can be ideal to limit your intake to 200 mg a day, according to Mayo Clinic.

When Should You Avoid
There are certain times when you are advised to avoid
caffeine to keep your blood pressure levels under control. In his Mayo Clinic
article, Sheldon G. Sheps, M.D. recommends avoiding caffeine prior to exercise,
weightlifting, or hard physical labor, since your blood pressure levels will
already be naturally elevated. According to the American Pregnancy Association,
women should avoid caffeine during pregnancy to reduce the risk of increased
blood pressure. Also be sure to avoid caffeine consumption before having your
blood pressure taken to help ensure an accurate test result.
Does caffeine raise blood pressure levels enough for you to
be concerned? People who fall into the normal blood pressure range generally
don't need to worry about it. If you have high blood pressure, it can't hurt to
limit your intake, but ask a licensed healthcare provider to find out how much
caffeine is safe for you.
