Aerobic training is known to regulate blood pressure more effectively when practiced in the evening than in the morning. Researchers who conducted a study of elderly patients concluded that evening exercise is better for blood pressure regulation thanks to improved cardiovascular control by the autonomic nervous system via a mechanism known as baroreflex sensitivity. "There are multiple mechanisms to regulate blood pressure, and although morning training was beneficial, only evening training improved short-term control of blood pressure by enhancing baroreflex sensitivity. This is important because baroreflex control has a positive effect on blood pressure regulation, and there aren't any medications...

Keeping blood pressure under control could be crucial for women in preventing uterine fibroids, new research shows. Middle-aged women tracked for up to 17 years in a new study were 37% less likely to develop these painful growths if they treated their high blood pressure with medication. On the other hand, "patients with new-onset hypertension had a 45% increased risk of newly reported fibroids," said a team led by Susannah Mitro. As outlined in the study, uterine fibroids are benign but painful tumors that arise in the uterus and affect up to 80% of women by the age of 50....

High blood pressure, or hypertension, remains a global health concern, contributing to 19% of deaths worldwide. In an international review, biologists highlight the pivotal role of dietary fiber in managing hypertension and reducing cardiovascular disease (CVD) risk, and call for the inclusion of dietary fiber in clinical guidelines for hypertension. The review sheds light on the often-overlooked importance of dietary fiber in blood pressure management. Said Francine Marques, "Dietary fiber has emerged as a crucial yet underappreciated part of hypertension management." "Our comprehensive analysis emphasizes the evidence supporting the effectiveness of dietary fiber in lowering blood pressure and reducing the...

Sleeping fewer than seven hours is associated with a higher risk of developing high blood pressure over time, according to a study. The current analysis pools data from 16 studies conducted between January 2000 and May 2023, evaluating hypertension incidence in 1,044,035 people from six countries who did not have a prior history of high blood pressure over a median follow-up of five years (follow-up ranged from 2.4 to 18 years). Short sleep duration was significantly associated with a higher risk of developing hypertension after adjusting for demographic and cardiovascular risk factors. Furthermore, the association was found to be even...

A study provides compelling evidence for clinical practice to direct efforts toward preventing white matter damage in individuals with hypertension in order to protect against cognitive decline and dementia. Gray matter is where the brain cells exist, whereas white matter constitutes the network of nerve fibers that provides the communication connection between different areas of gray matter. The study, led by Dr. Jing Du, found that compared with gray matter, white matter is more vulnerable to raised blood pressure. "Because gray matter has a greater amount of small blood vessels, and therefore a greater supply of blood compared to white...

More than half of adults living in the U.S. label themselves as "mouth breathers"—breathing primarily through an open mouth. However, according to research, breathing through the nose leads to several benefits, including lower blood pressure and other factors that could predict heart disease risk. Blood pressure and heart rate can be predictors of heart disease. Breathing patterns can affect these bodily functions due to the crosstalk that occurs between the respiratory and cardiovascular systems. Nasal breathing has been shown to relax the airways and improve breathing efficiency. A group of 20 young adult volunteers participated in a crossover study consisting...

New research in the Journal of the American Heart Association from Columbia and partnering universities found an uncanny connection between couples and high blood pressure. “Many people know that high blood pressure is common in middle-aged and older adults, yet we were surprised to find that among many older couples, both husband and wife had high blood pressure in the U.S., England, China and India,” said senior study author Chihua Li. “For instance, in the U.S., among more than 35% of couples who were ages 50 or older, both had high blood pressure.” In total, about 38% of U.S. spouses...

Millions of people with normal blood pressure may be misclassified as having blood pressure that is too high because of improper positioning when measurements are taken, research suggests. Guidelines call for a patient to be seated in a chair with feet flat on the floor, their back supported and the arm wearing the blood pressure cuff supported at heart level. Doing so helps ensure an accurate reading. But many health care professionals take blood pressure measurements while the patient is seated on an examining table, leaving their legs to dangle and their back and arm unsupported. Being misclassified with high...

Your morning alarm clock might not just be annoying. It could be raising your blood pressure, putting you at greater risk for adverse cardiovascular events, such as stroke and heart attack, according to research. Yeonsu Kim studied how being forced awake contributes to morning blood pressure surge, an increase in blood pressure that happens when people move quickly from being asleep to awake. Kim studied 32 participants over two days. The first night, they were told to awaken naturally, without an alarm. The second night, they were instructed to set an alarm to awaken them after only five hours of...

A 12-week course of daily beetroot juice supplement for people with chronic obstructive pulmonary disease (COPD) lowered blood pressure and improved how far patients could walk in six minutes in research. COPD includes chronic bronchitis and emphysema, causes breathing difficulties and severely limits people's capacity for physical activity. The new research tested a concentrated beetroot juice supplement that is high in nitrate against a beetroot juice placebo. Professor Nicholas Hopkinson said, "There is some evidence beetroot juice as a source of nitrate supplementation could be used by athletes. Higher levels of nitrate in the blood can increase the availability of...

Short sleep lengths, daytime napping and even long sleep lengths have been linked to an increased risk of elevated blood pressure and cardiovascular disease, a new study has found. Using data from the UK Biobank, the study is the first study to demonstrate that independent of other factors, circadian rhythm-disrupting behaviors, including shift work, have an adverse effect on blood pressure regulation. "We found that compromised sleep health or nightshift work are associated with elevated blood pressure in both males and females and across all age groups," Professor Morag Young said. "What we've found is that having circadian rhythms out...

Nearly everyone can lower their blood pressure, even people currently on blood pressure- reducing drugs, by lowering sodium intake, reports a study. "In the study, middle age to elderly participants reduced salt intake by about one teaspoon a day compared with their usual diet. The result was a decline in systolic blood pressure by about 6 millimeters of mercury (mm Hg), which is comparable to the effect produced by a commonly utilized first-line medication for high blood pressure," said Deepak Gupta, M.D., MSCI. "We found that 70-75% of all people, regardless of whether they are already on blood pressure medications...

Measuring blood pressure while patients are standing rather than sitting may improve the accuracy of readings, researchers report. Their findings could lead to significant improvements in early detection of high blood pressure in healthy adults. UTSW researchers measured the blood pressure of 125 healthy patients ages 18-80 with no history of hypertension, previous use of blood pressure medication, or other comorbidities. The statistical analysis used to assess the overall accuracy of each test in diagnosing hypertension revealed that measuring standing blood pressure either on its own or in addition to sitting blood pressure significantly improved diagnostic accuracy. Researchers used several...

An estimated 40% of the global adult population have high blood pressure, or hypertension, which puts people at risk of cardiovascular disease and other dangerous health conditions. Recent studies suggest that probiotics may offer a protective effect. A study adds two new strains to the list of potential antihypertensive probiotics. In experiments on hypertensive mice, treatment with the two probiotics, Bifidobacterium lactis and Lactobacillus rhamnosus, returned blood pressure to normal levels. Previous studies have connected the rising rates of hypertension worldwide to increasing consumption of sugar. It likely boosts blood pressure through many mechanisms—increased insulin resistance or salt retention, for...

An estimated 80% of older adults in the U.S. have high blood pressure. A study found that adding a relatively minimal amount of movement, about 3,000 steps per day, can significantly reduce high blood pressure in older adults. This study sought to determine if older adults with hypertension could receive these benefits by moderately increasing their daily walking, which is one of the easiest and most popular forms of physical activity for this population. The study focused on a group of sedentary older adults between ages 68 and 78 who walked an average of about 4,000 steps per day before...

Antihypertensive use is associated with a reduced risk for dementia compared with untreated hypertension, according to research. Matthew J. Lennon, M.D. and colleagues examined the associations of hypertension history, antihypertension use, and baseline-measured blood pressure (BP) in late life with dementia in longitudinal, population-based studies of aging adults participating in the Cohort Studies of Memory in an International Consortium group. The analysis included 17 studies with 34,519 community-dwelling older adults (mean age, 72.5 years) and a mean follow-up of 4.3 years. The researchers found that individuals with untreated hypertension had a significantly increased risk for dementia compared with healthy controls...

People who had high blood pressure while lying flat on their backs had a higher risk of heart attack, stroke, heart failure or premature death, according to research. The autonomic nervous system regulates blood pressure in different body positions; however, gravity may cause blood to pool when a person is seated or upright, and the body is sometimes unable to properly regulate blood pressure during lying, seated and standing positions. To examine body position, blood pressure and heart health risk, the researchers examined health data from the longitudinal Atherosclerosis Risk in Communities (ARIC) study. 16% percent of participants who did...

Miscuffing results in inaccurate blood pressure (BP) measurements, according to a study. Junichi Ishigami, M.D., M.P.H. and colleagues examined the effects of using a regular BP cuff versus an appropriately sized BP cuff on automated BP readings in a randomized crossover trial of community-dwelling adults. A total of 195 adults underwent four sets of triplicate BP measurements, using an appropriate, too-small, or too-large BP cuff in random order, followed by a fourth set with an appropriate BP cuff. The difference in mean BP when measured with a regular BP cuff compared to an appropriate BP cuff was assessed as the...

Static isometric exercises—the sort that involve engaging muscles without movement, such as wall sits and planks—are best for lowering blood pressure, finds a pooled data analysis of the available evidence from clinical trials. In a bid to potentially update information on the best form of exercise for controlling blood pressure, they trawled research databases looking for clinical trials reporting the effects of an exercise training intervention lasting two or more weeks on resting blood pressure. The exercise interventions were classified as aerobic (cardio); dynamic resistance training; a combination of these; HIIT; and isometric exercises. Healthy resting blood pressure was defined...

Purpose The most important variable risk factor for developing glaucoma is intraocular hypertension. Timely lowering of high intraocular pressure (IOP) significantly lowers the likelihood of developing glaucoma. The aim of this study was to evaluate the effects of the food supplement Mirtogenol® (Mirtoselect® and Pycnogenol®) on IOP and ocular blood flow in a product evaluation study. Methods Thirty-eight asymptomatic subjects with intraocular hypertension were either given Mirtogenol® (20 subjects) or were not treated (18 subjects). The visual acuity, IOP, and ocular blood flow were measured at two, three, and six months. Results After two months of supplementation with Mirtogenol®, the...
