Natural Health News – The next time you are shopping for food, be sure to pick up a watermelon – or two. It could save your life.
A new study by Florida State University Associate Professor Arturo Figueroa, published in American Journal of Hypertension found that watermelon contains substances that help cold reduced blood pressure and related health problems.
Figueroa has conducted several studies on the benefits of watermelon. In the past, it discussed the impact function of blood post-menopausal women and blood pressure readings of adults with pre-hypertension .
So the team decided to investigate whether watermelon – or more specifically amino acids containing -. They could also help reduce the risk of stroke or heart attack due to environmental stress
More people die of heart attacks in cold weather. This is due to the stress of low temperature it causes blood pressure to increase and the heart has to work harder to pump blood into the aorta, leading to a decreased blood flow to the heart.
Therefore, people with obesity and high blood pressure face a higher risk of stroke or heart attack when exposed to cold, either during the winter or in rooms with low temperatures.
The warm climate fruit relieves cold stress
The 12-week study, focused on 13 obese men and middle-aged women who also suffered from high blood pressure. To simulate cold weather conditions, a part of the subject is immersed in water of 39 ° F (4 ° C), while scientists took their blood pressure and other vital measures.
Meanwhile, the group split into two. During the first six weeks, one group received four grams of the amino acid L-citrulline and two grams of L-arginine per day, both watermelon extract. The other group received a placebo for 6 weeks.
Then changed for the second six weeks.
Participants also had to refrain from taking any medication for blood pressure or make any significant changes in their lifestyle, particularly in relation to diet and exercise during the study.
The results showed that consumption of watermelon had a positive impact on aortic blood pressure and other vascular parameters.
In particular, the study participants showed improvements in blood pressure and heart stress while at rest and when exposed to cold water.
“The pressure in the aorta and heart decreased after consuming watermelon extract,” Figueroa said. “That means less strain on your heart, so the heart will easily work during a stressful situation such as exposure to cold.”
