In a recent study, researchers from the University of California, Irvine (UCI) and the University of Copenhagen, in Denmark, found that antioxidants in tea open ion channels and can relax the muscles that line blood vessels, which may lower the blood pressure.
The researchers demonstrated, for the first time, that two antioxidants in tea, known as catechins, open a protein channel in the membranes of the smooth muscle cells that line blood vessels. This allows positively charged potassium ions to leave the cells.
For their study, the scientists used computer modeling and mutated versions of the channel protein to show that the two catechins bind to a section that senses voltage changes.
Senior study author Prof. Geoffrey Abbott, of the Department of Physiology & Biophysics at the UCI School of Medicine, explains: “This binding allows the channel to open much more easily and earlier in the cellular excitation process.”
A new study, carried out by researchers from the University of California in San Francisco, US, finds that people who walk more also have lower blood pressure.
For the study, the scientists analyzed data provided by 638 participants within the study called the Framingham Heart Study. The participants were prescribed to wear an Apple Watch every day for at least 5 hours.
The device recorded the number of steps made every day. Also, all the participants had to measure their own blood pressure on a weekly basis at home during the study period (5 months).
Lead author Dr. Mayank Sardana says: “This study solidifies our understanding of the relationship between physical activity and blood pressure and raises the possibility that obesity or [BMI] accounts for a lot of that relationship. […] It would be useful to look at how smart devices might be leveraged to promote physical activity, reduce the burden of obesity, and potentially reduce blood pressure.”
A new study from the Asklepieion General Hospital in Voula, Greece, suggests that having a midday nap is not only good for boosting your energy but also can lower high blood pressure.
For the study, the researchers examined 212 people with the mean blood pressure of 129.9 mm Hg. The participants’ average age was 62 years. During the study, the analysis showed that people who took a midday nap experienced 5.3 mm Hg drop in systolic blood pressure.
One of the study researchers, Dr. Manolis Kallistratos says: “These findings are important because a drop in blood pressure as small as 2 mm Hg can reduce the risk of cardiovascular events, such as heart attack by up to 10 percent.”
Drinking kefir, fermented milk drink, has been proved to have many health benefits. In a new study, the scientists from Auburn University in Alabama, USA, and the University of Vila Velha in Espirito Santo, Brazil, explained how it can protect cardiovascular health.
For the study, they worked with a rat model trying to see if kefir’s probiotic properties could influence gut health and help to lower blood pressure.
After analysis of the received data, the scientists concluded that the rats who regularly consumed kefir for 9 weeks, showed lower levels of endotoxins, harmful substances that contribute to inflammation. These rats also demonstrated lower blood pressure and improved intestinal structure.
According to a study, recently published in the journal Psychological Science, the more time you spent with your best friends in childhood, the likelier you have a healthy weight and blood pressure in adulthood.
For the study, the researchers analyzed data from a large study of 267 adults whose social lives were monitored between the ages of 6 and 16. The results of the analysis showed that adults who used to spend a lot of time with their buddies in childhood had lower blood pressure levels and body mass index (BMI) at the age 32.
Jenny M. Cundiff, one of the study authors from Texas Tech University in Lubbock, USA, says: “These findings suggest that our early social lives may have a small protective influence on our physical health in adulthood, and it’s not just our caregivers or financial circumstances, but also friends who may be health protective.”
