Five minutes of exercise a day could lower blood pressure

Findings show importance of activities that raise heart rate for blood pressure control

2024-11-07
(Press-News.org) New research suggests that adding a small amount of physical activity – such as uphill walking or stair-climbing – into your day may help to lower blood pressure.  

The study, published in Circulation, was carried out by experts from the ProPASS (Prospective Physical Activity, Sitting and Sleep) Consortium, an international academic collaboration led by the University of Sydney and University College London (UCL).  

Just five minutes of activity a day was estimated to potentially reduce blood pressure, while replacing sedentary behaviours with 20-27 minutes of exercise per day, including uphill walking, stair-climbing, running and cycling, was also estimated to lead to a clinically meaningful reduction in blood pressure. 

Joint senior author Professor Emmanuel Stamatakis, Director of the ProPASS Consortium from the Charles Perkins Centre said: “High blood pressure is one of the biggest health issues globally, but unlike some major causes of cardiovascular mortality there may be relatively accessible ways to tackle the problem in addition to medication.” 

“The finding that doing as little as five extra minutes of exercise per day could be associated with measurably lower blood pressure readings emphasises how powerful short bouts of higher intensity movement could be for blood pressure management.” 

Hypertension, or a consistent elevated blood pressure level, is one of the biggest causes of premature death globally. Affecting 1.28 billion adults around the world, it can lead to stroke, heart attack, heart failure, kidney damage and many other health problems, and is often described as the ‘silent killer’ due to its lack of symptoms.  

The research team analysed health data from 14,761 volunteers in five countries to see how replacing one type of movement behaviour with another across the day is associated with blood pressure.  

Each participant used a wearable accelerometer device on their thigh to measure their activity and blood pressure throughout the day and night.  

Daily activity was split into six categories: sleep, sedentary behaviour (such as sitting), slow walking, fast walking, standing, and more vigorous exercise such as running, cycling or stair climbing. 

The team modelled statistically what would happen if an individual changed various amounts of one behaviour for another in order to estimate the effect on blood pressure for each scenario and found that replacing sedentary behaviour with 20-27 minutes of exercise per day could potentially reduce cardiovascular disease by up to 28 percent at a population level.  

First author Dr Jo Blodgett from the Division of Surgery and Interventional Science at UCL and the Institute of Sport, Exercise and Health said: “Our findings suggest that, for most people, exercise is key to reducing blood pressure, rather than less strenuous forms of movement such as walking.  

“The good news is that whatever your physical ability, it doesn’t take long to have a positive effect on blood pressure. What’s unique about our exercise variable is that it includes all exercise-like activities, from running for a bus or a short cycling errand, many of which can be integrated into daily routines.  

“For those who don’t do a lot of exercise, walking did still have some positive benefits for blood pressure. But if you want to change your blood pressure, putting more demand on the cardiovascular system through exercise will have the greatest effect.” 

Professor Mark Hamer, joint senior author of the study and ProPASS Deputy Director from UCL, said: “Our findings show how powerful research platforms like the ProPASS consortium are for identifying relatively subtle patterns of exercise, sleep, and sedentary behaviour, that have  significant clinical and public health importance.”

Social media likes and comments linked to young men’s obsession with perfect pecs and a six-pack

2024-11-06
Social media platforms like TikTok and Instagram are fuelling unrealistic, unhealthy obsessions with a lean and muscular physique among many young men, according to a new Australian study. Men who place higher importance on receiving likes and positive comments on their posts are significantly more likely to experience symptoms of what is termed “muscle dysmorphia” (MD) – a belief that their bodies are small and weak, even though many of them have a good physique. In an online survey of almost 100 men, aged between 18-34, all admitted to viewing celebrity, fashion, and fitness content on social media sites, but the link with MD was only significant when it came to ...

$2.1M aids researchers in building chemical sensors to safeguard troops
2024-11-06
The U.S. Army has awarded a team of researchers led by Judith Su, University of Arizona associate professor of biomedical engineering and optical sciences, $2.1 million to build a handheld version of her record-breaking FLOWER sensing device for active military personnel. The device picks up target compounds at zeptomolar (10 to the power of negative 21) concentrations, an astonishingly minuscule amount of 600 particles per liter. FLOWER is useful for drug testing and a wide variety of other applications, such as health diagnostics.  The military ...

Climate change parching the American West even without rainfall deficits

2024-11-06
Key takeaways Higher temperatures caused by anthropogenic climate change turned an ordinary drought into an exceptional one that parched the American West from 2020–2022.  A study by UCLA and NOAA scientists has found that evaporation accounted for 61% of the drought’s severity, while reduced precipitation accounted for 39%.  The research found that since 2000, evaporative demand has played a bigger role than reduced precipitation in droughts, which may become more severe ...

Power grids supplied largely by renewable sources experience lower intensity blackouts
2024-11-06
New research into the vulnerability of power grids served by weather-dependent renewable energy sources (WD-RESs) such as solar and wind paints a hopeful picture as various countries around the globe attempt to meet their climate emissions targets – with the research showing grids with high penetration of WD-RESs tend to have reduced blackout intensities in the US. This research – just published in leading international journal Nature Energy – was conducted with US blackout data from 2001 to 2020, but the results are of great interest from the perspective of any country transitioning to power grids primarily ...

Mayo Clinic researchers recommend alternatives to hysterectomy for uterine fibroids, according to study

2024-11-06
ROCHESTER, Minn. — Uterine fibroids are a common condition that affects up to 80% of women in their lifetime. Nearly half of those women will experience symptoms that affect their quality of life and fertility, including severe pain and anemia. Uterine fibroids are the major reason for the removal of the uterus by hysterectomy. However, Mayo Clinic researchers recommend minimally invasive treatment alternatives to hysterectomy, in an invited clinical practice paper published in the New England Journal of Medicine. "Less invasive ...

Very early medication abortion is effective and safe

2024-11-06
Clinics and hospitals currently defer medication abortion until ultrasound confirms a pregnancy inside the uterus. However, a large international study led by researchers from Karolinska Institutet now indicates that treatment can be equally effective and safe even before the sixth week of pregnancy. The study is published in The New England Journal of Medicine. 35,550 abortions took place in Sweden in 2023, over 60 per cent of them before the end of the seventh week of pregnancy. Often, the procedure is held off until intrauterine pregnancy is confirmed by vaginal ultrasound to rule out the possibility of an ectopic pregnancy, in which the embryo attaches ...
