It is known that salt intake can affect our body temperature and blood pressure. Researchers keep on doing research on this subject. Recently, a study done at Case Western Reserve University School of Medicine and Kent State University gave some concluding findings. According to this research Salt intake can raise the blood pressure because our cardiovascular system finds it hard to regulate blood pressure and body temperature. For many years medical researchers have been doing research on hypertension, which is caused by salt-induction.
They have found that some people are sensitive to salt, whereas other people are salt resistant. This is difficult to explain why some people have a different response towards salt. Researchers and scientists have tested to find out the dual roles of the cardiovascular system so that they can explain how salt ingestion causes salt-sensitive hypertension. This team of researchers included, Robert P.Blankfield MD and MS, a clinical professor of family medicine at Case Western Reserve University School of Medicine, and Ellen L.Glickman PhD, professor of science at Kent State University.
The test was conducted on 22 healthy men; a group was given only water, whereas the second group was given salt and water. After every hour that the subjects consumed salt and water or just water, their blood pressure, temperature, cardiac index and urine output were monitored.
The researchers found that salt and water lowered body temperature at a faster rate than by just taking water. They also found that the temperature of the body decreased more in men who is salt resistant than in men who is salt sensitive. The temperature is well maintained in men who is salt sensitive, but they suffered from higher blood pressure Blankfield says that people who are salt sensitive are able to have a more stabilized body temperature in comparison to those who salt resistant individuals.
So this theory can explain hypertension due to salt-induction. A research fellow, Matthew D.Muller at the Penn State College of Medicine said in his paper, that we can understand the role of salt in producing hypertension and high blood pressure. Those who consumed salt and water had a higher level blood pressure and hypertension. Whether this increase in blood pressure is brief or prolonged, it causes changes in the walls of the arteries, thus affecting our heart.
He says that, these days the doctors tell their patients that the real cause of high blood pressure is still unknown. But after the above mentioned theory soon the doctors will be able to explain to their patients the reason of high blood pressures.
In the journal entitled Hypertension Research, an article, on the subject, was published in the issue of 14th of April.
