High blood pressure, or hypertension is one of the more common medical conditions worldwide. Luckily, doctors screen for high blood pressure at most check-ups, so if you do have it, it’ll be caught quickly and you can reduce your risk with easy lifestyle changes.
First things first: If you’re worried about high blood pressure, speak to your doctor. It’s a condition that can have serious long-term ramifications for your health, experts warn – with hypertension being a leading cause of strokes and heart attacks. “Blood pressure measures the force that one’s heart requires to push blood through the blood vessels and the arteries to supply oxygen and nutrition to the body’s organs,” says Mayo Clinic cardiologist Dr Elijah Behr. “If it is too high, it can cause damage to the organs, especially the heart itself, the brain and the kidneys. High blood pressure is also a common cause of cardiovascular disease.”
If you’re curious about what it takes to lower your blood pressure, or just want to keep an eye on your health with lifestyle changes you can implement now, we’ve got you covered with advice from experienced doctors and nutritionists.
• How to lower blood pressure
1. Stop drinking alcohol
To lower your blood pressure, stop drinking alcohol as it can have serious effect on your heart by narrowing blood vessels, making it harder for the heart to pump blood around the body.
It can also trigger the release of hormones like cortisol and adrenaline, which are linked to stress and raise blood pressure almost immediately.
While it’s best to avoid alcohol completely, if you’re looking to learn how to lower blood pressure, cutting down is a good first step. “You should limit alcohol intake to no more than two drinks twice a week,” says Dr Chinelo Ojukuwu, a GP at Pall Mall Medical with over 20 years of experience.
2. Relax
While it’s important to learn how to lower your cortisol levels and prevent stress on a longer-term basis, relaxing can help lower blood pressure quickly.
“Practice stress-reduction techniques such as mindfulness, meditation, deep breathing exercises, yoga, or hobbies that promote relaxation,” says Dr Shirin Lakahni, a registered GP.
3. Drink some water
If your blood pressure has risen suddenly, research suggests that drinking a glass of water – and maintaining a healthy water intake throughout the day can lower it.
A study from Central South University found that drinking the recommended six to eight cups of water per day had a “favourable” effect on blood pressure in adults.
“When it comes to drinks, consuming caffeine and alcohol may increase your blood pressure,” says Vitality’s registered nutritionist James Vickers. “It’s advisable to limit the amount you consume. Instead, reach for water or juices such as apple, tomato or pomegranate juice which can all help to lower your blood pressure.
4. Get some sleep
If you’re experiencing high blood pressure, learning how to sleep better is one of the best ways to lower it. “Aim for seven to nine hours of quality sleep per night,” says Dr Lakhani. “Poor sleep can contribute to weight gain, high blood pressure, and other risk factors for heart disease.”
Sleep and stress are also innately linked. You might feel more stressed if you consistently aren’t sleeping very well, and vice versa. Speak to your doctor about possible further lifestyle recommendations and treatments if this is the case.
5. Do some exercise
Exercise is both a quick fix for high blood pressure and a way to reduce hypertension in the future. “Walking, swimming, and cycling are all beneficial exercises as they get the heart pumping but are low impact, which means they are gentler on the joints and may be suitable for people experiencing musculoskeletal issues too,” says Dr Lakhani.
“Weight training [also known as resistance or strength training] can be beneficial as well, as it helps to maintain muscle mass that naturally decreases as one ages.
The NHS recommends at least 150 minutes of moderate-intensity exercise every week. This means working out to the level where you feel slightly uncomfortable but can still maintain a conversation. These minutes can be spread throughout the week by going swimming every day, for example, or in three longer sessions.
6. Lower your stress levels
Chronic stress – that’s stress that’s ongoing for weeks, months, and potentially even years, leading to burnout from work and other serious mental health conditions – can have a seriously negative impact on heart health. So as well as practising relaxation tips in the moment, it’s important to reduce stress on a longer-term basis, says Dr Lakhani.
7. Limit salty foods
Salt gives our food flavour, but it’s something to avoid if you’re looking to learn how to lower blood pressure. Salt is sodium, which is perfectly fine in smaller amounts but if you eat a lot of salty food, it can cause the body to retain fluid (which also causes bloating). This increases blood volume and pressure exerted against the blood vessels’ walls.
“You can try switching salt with things like herbs and spices when you cook to ensure you don’t miss out on flavour,” says Vickers.
8. Eat a heart-healthy diet
However, the experts say the best way to lower blood pressure in the long term is to change your lifestyle. Most importantly, Dr Lakhani says: “Cut your sodium intake and eat more fruits, vegetables, protein, and fibre.”
It’s also a good idea to limit processed foods, refined carbohydrates, added sugars, and ‘unhealthy’ fats, she notes. “These can contribute to inflammation, weight gain, and an increased risk of heart disease. Eating a varied and balanced diet, and maintaining a healthy weight and active lifestyle, can help support heart health.”
9. Talk to your doctor
As with all medical concerns, it’s best to speak to your doctor if you’re concerned about high blood pressure and want to know how to lower it effectively. They’ll be best placed to answer your questions.
Your doctor can also suggest alternatives if lifestyle changes don’t do the trick. “”You might be prescribed antihypertensives to help keep your blood pressure under control, says Dr Lakhani.
“The choice very much depends on how well an individual will tolerate the medication, especially if there are side effects,” adds Dr Behr. “Very occasionally, keyhole procedure can be untaken to reduce very resistant blood pressure, known as renal artery denervation or ablation.”
• Foods that can help lower blood pressure
* Fatty fish: Fish like salmon, tuna and mackerel are great sources of omega-3 fatty acids, which can help lower blood pressure.
* Leafy green vegetables: This includes spinach and kale, pumpkin leaves, bitter leaf, other leafy vegetables which are rich in various vitamins and minerals.
* Sources of healthy fats: Nuts, olive oil, avocado, and seeds, for example.
* Wholegrains: Grains such as brown rice, barley, quinoa, and bulgar all count as wholegrains.
* Low-fat dairy: Fat-free or 1% yoghurt, cheese, and milk can be beneficial foods for those who want to lower their blood pressure.
* Sources of lean protein: Chicken, fish, turkey breast, beans, lentils, and chickpeas are all examples of lean protein.
• Does eating bananas help lower blood pressure?
Bananas are another food recommended by experts to help lower blood pressure as it’s rich in potassium. This mineral has been shown, via studies in the Journal of Human Hypertension, to help get rid of sodium in the body and reduce the effects of sodium on the blood vessels. It also helps relax the blood vessels.
One banana contains 420mg of potassium, which works out at 11% of the 16mg daily recommended intake.
