The blood pressure brings many people to the head and the hypertension it’s already a health problem to global level that affects 1.280 million adults, according to the World Health Organization (WHO). Spain is in the tail of Europe Regarding patients with this silent ailment, main risk factor in cardiovascular and cerebrovascular diseases: 14 million adults suffer from it. In other words, 42.6% of the population over 18 years of age is hypertensive, specifies the study ‘[email protected]’ of the Spanish Heart Foundation (FEC). There is not one cause concrete for this disease, but there are different guidelines to have it under controlas the medication and a low sodium diet. Now, Japanese scientists say there is a totally natural method to combat the prevalence of this condition: thermal baths.
The researchers of the Beppu Hospital of the Kyushu University have linked the fact of bathing in hot springs at more than 40 degrees of temperature, which in Japan is called ‘onsen’, with a decrease in blood pressure. Specifically, they have found evidence that this type of bathroom, especially made at nightabsorb the lowest cases of hypertension in people older than 65 years.
The history of humanity with hot springs dates back to the Ancient Egypt, more than 5000 years ago. There is even reference to the ‘onsen’ in the oldest books of Japan and in the myths of creation, these scientists recall. In addition, people have promoted the health benefits to submerge in this type of water until well into the modern era.
“I wanted to find out if the onsen baths in the long term they had some preventive effect on hypertension. Previous research has shown that the traditional thermal therapy and hot spring baths are effective against various diseases, including hypertension,” explains Satoshi Yamasaki, professor of internal medicine at Beppu Hospital and first author of the study. In addition, he points out that the high pressure It is “the leading cause of hospital visits in Japan and long-term drug use.”
Study carried out with data from 11,000 people
The research collects information since 2011 on the medical historythe habits of hot springs and even what kind of ‘onsen’ they frequent more than 11,000 people, almost a third of the residents of Beppu older than 65 years. It should be noted that in Japan there are more than 27,000 health sources, of which 3,085 are hot springs.
From the data set, Yamasaki’s team was able to conclude that 4,001 people currently have high blood pressure or a history of the disease. He also corroborated that having high blood pressure also increases the probability that the individual has other pathologies, such as drop, arrhythmiasa renal disease and diabetes.
“He was observing the onsen habits of an individual when we find something interesting. Then we found out that people who bathed in hot springs after 7 p.m. have about 15% less likely to have hypertension”details Yamasaki in the study published in the journal ‘Scientific Reports’edited by ‘Nature’, on November 14.
Less stress and better sleep
The team hypothesizes two main reasons for these findings: lower stress and one faster falling asleep. Along these lines, the scientist points out that previous research has shown that a faster onset of sleep can improve its quality and improve control of hypertension. In addition, it has been shown that thermal therapies, such as sauna bathsrelease the tension and help to relaxthus decreasing the levels of macadores of blood stresswhich also leads to a better blood pressure relief.
