hypertension simply means force with which your heart have to push blood into the blood vessels against resistance . body temperature depends on your higher brain functions and some basic physiological structures e.g sweat glands , cutaneous blood flow , vasodilation or constriction etc
Usually it would cause low blood pressure from dehydration and hypovolemia.
Decreasing the temperature of the system would NOT cause an increase in pressure. According to the ideal gas law, pressure and temperature are directly proportional when other variables are constant. Therefore, decreasing the temperature would result in a decrease in pressure.
Because blood is liquid, its boiling point is affected by pressure changes. Extremely low pressure would lower the boiling point enough that the blood would boil at a temperature less than body temperature.
If you mean that your skin is flushed, then it can happen when you drink alcohol. Alcohol can raise blood pressure. You may also have high blood pressure even if you avoid alcohol. You can check your blood pressure yourself at those 'do-it-yourself' BP boothes at many drug stores. Or you can get a checkup at the doctors. Also, if the ambiant temperature where you live is high, the high heat can cause flushing as well. There are certain foods that can cause high blood pressure, such as licorise. Hope that is what you are looking for.
temperature increase The pressure of a contained sample of gas can be increased by increasing its temperature, or by decreasing its volume, or by injecting additional mass into it.
it is hard to say exactly how long it takes but it is roughly 2-3months as doing it to soon can cause high blood pressure and can cause heart attacks so it would be best to wait 2-3 months to let your blood enhabit its temperature this question relates to a passenger!
Blood pressure would decrease
An increase in temperature would cause air pressure to rise. As air warms, its molecules gain more kinetic energy and spread further apart, leading to an increase in pressure. Cold air entering a region or moisture entering the air would not directly cause air pressure to rise.
The kidneys retain salt when the blood pressure is low. This keeps fluid in the body, thus maintaining the blood pressure. The kidneys cause vasoconstriction in the body when the blood pressure is low. This raises the blood pressure.
high
I would say yes. If you got hit in the head there may be an internal bleeding whereas the blood may also clot. There is no spac to get that bad blood out so as the blood increases there is pressure placed on that side or that area where you got the hit causing your heart pressure to rise then leading to High Blood Pressure.
There are several things that can cause this. Hypovolemic shock comes to mind. This means you may have too little blood flowing in your body. This, by its self, will cause your blood pressure to fall. When your body recognizes that the blood pressure is too low (because your tissues will not be being perfused adequately), your heart rate will increase to attempt to compensate for the low blood pressure.
