does your blood pressure go up when you have a fever?

And if you're sick or in pain, it's normal for your blood pressure to be higher than usual. If your blood pressure is consistently high, this is considered high blood pressure (also known as hypertension.) High blood pressure makes your heart work harder than it should.

Blood pressure generally is higher in the winter and lower in the summer. That's because low temperatures cause your blood vessels to narrow — which increases blood pressure because more pressure is needed to force blood through your narrowed veins and arteries.

The researchers report that another study has found that eating hot chillies causes a temporary increase in blood pressure in humans, but that the longer-term effects are not known. Until more research is done, people with high blood pressure should not try substituting their blood pressure medication with chillies.

A fever is a temporary increase in your body temperature, often due to an illness. Having a fever is a sign that something out of the ordinary is going on in your body. For an adult, a fever may be uncomfortable, but usually isn't a cause for concern unless it reaches 103 F (39.4 C) or higher.

But sometimes blood pressure rises so quickly and severely that it becomes a medical emergency requiring immediate treatment, often with hospitalization. In these situations, high blood pressure can cause: Memory loss, personality changes, trouble concentrating, irritability or progressive loss of consciousness. Stroke.

And you shiver and raise your body temperature to that elevated level. When the fever breaks, the thermostat gets set back to 98.6. That's when you start to sweat, throw off the covers, and hopefully begin to feel better.

So, while it's not exactly a fever, a slight uptick in your body's temperature may clue you in to the fact that your progesterone is higher than usual. But if you find yourself with symptoms of a fever, like body chills or aches and pains, be sure to visit your doctor.

During the stress response, your adrenal glands are stimulated and produce adrenaline, which causes your heart rate to increase and your blood pressure to rise. This increased heart rate can raise blood pressure and cause a hot flush.

You probably have high blood pressure (hypertension) if your blood pressure readings are consistently 140 over 90, or higher, over a number of weeks. You may also have high blood pressure if just one of the numbers is higher than it should be over a number of weeks.

Viral infections like the flu also put added stress on your body, which can affect your blood pressure, heart rate, and overall heart function. That can raise your odds of having a heart attack or stroke. But none of this has to happen. The flu is easy to prevent.

A flu infection does this by increasing the stress on the heart -- increasing heart rate, blood pressure and increasing intrinsic stress hormones called catecholamines. It's a considerable "stress test" on the heart, and for those who have little reserve, they may not be able to handle it.

Fever causes an increase in the heart rate, breathing rate and blood circulation to the skin. This is how the body tries to reduce the heat caused by fever. The symptoms of fever can include: Feeling and/or looking unwell.

These fluctuations generally happen within a normal range. But when blood pressure regularly spikes higher than normal, it's a sign that something isn't right. Doctors call the condition labile hypertension, and it merits investigation.

While facial flushing may occur while your blood pressure is higher than usual, high blood pressure is not the cause of facial flushing.

Short term: Your heart beats harder and faster and your blood vessels dilate, pushing more blood into your large muscles and raising your blood pressure. Long term: Consistently elevated heart rate, blood pressure, and stress hormones can increase your odds of heart attack, stroke, and hypertension.

Blood pressure might rise during a heart attack because hormones, such as adrenaline, are released. These hormones are released when the “fight or flight” response is triggered at times of intense stress or danger. This automatic response might make the heart beat faster and stronger.

Many people think that blood pressure rises as the heart beats faster. That's not true, according to the American Heart Association. Healthy blood vessels dilate when the heart pumps faster, allowing blood to flow through more easily.
