But what if we go to an environment with higher or lower pressure?
It turned out to be low blood pressure, and I found another doctor.
This could be a problem if you already have low blood pressure.
The front then died out, but it left behind two areas of low pressure.
Also an important source of energy was water power at low or high pressure.
Why low pressure would do that is not certain, he says.
People who say they are happy tend to have low blood pressure.
For some people, it also helps lower high blood pressure a little.
Many people with low blood pressure don't have any symptoms.
At times the low pressure and lack of water was dangerous.
