High blood pressure, also known as hypertension, is a condition where the force of blood against the artery walls is consistently too high.

Understanding blood pressure numbers
Blood pressure is recorded as two numbers:

• Systolic (top number): pressure when your heart beats.
• Diastolic (bottom number): pressure when your heart rests between beats.

Category	Systolic (mmHg)	Diastolic (mmHg)
Normal	Under 120	Under 80
Pre-high (at risk)	120–139	80–89
High (Stage 1)	140–159	90–99
High (Stage 2)	160+	100+
Severe (Hypertensive crisis)	180+	120+

Hypertension is often referred to as the "silent killer" because it can lead to severe health problems without showing any clear symptoms.

1. Overworks your heart
   • High BP forces your heart to pump harder, which can cause the heart muscle to thicken or weaken.
   • This increases the risk of heart failure, heart attacks, and arrhythmias.
2. Damages arteries: constant high pressure can cause arteries to become narrow, stiff, or clogged, reducing blood flow. This can lead to: Atherosclerosis (hardening of the arteries), Heart attack, Stroke.
3. Possibility of a stroke
   • High BP is the #1 risk factor for stroke.
   • It can cause blood vessels in the brain to burst or become blocked, leading to brain damage or death.
4. Harmful effects on kidneys
   • High BP can damage the blood vessels in the kidneys, leading to chronic kidney disease or even kidney failure.
5. Affects vision
   • It can damage the delicate blood vessels in the eyes, causing hypertensive retinopathy, which can lead to vision loss or blindness.
6. Causes pognitive Problems
   • Over time, high BP reduces blood flow to the brain, increasing the risk of dementia, memory loss, and reduced cognitive function.

Fortunately, in many cases, you can manage or even reduce high blood pressure through natural lifestyle changes.

Here are some GP-approved tips to naturally control high blood pressure.

1. Adopt a heart-healthy diet

Your diet has a major impact on your blood pressure. Focus on the Dietary Approaches to Stop Hypertension (DASH diet), which emphasises:

1. Eat plenty of fruits and vegetables
   • Aim for 4-5 servings of vegetables and 4-5 servings of fruits per day.
   • These are rich in potassium and fibre, which help regulate blood pressure.
   • Examples: spinach, broccoli, berries, bananas, oranges, carrots, sweet potatoes.
2. Choose whole grains
   • Whole grains provide fibre, which supports heart health and helps with weight management.
   • Examples: Brown rice, quinoa, oats, whole-wheat bread and pasta.
3. Include low-fat or fat-free Dairy
   • Aim for 2-3 servings per day.
   • Dairy provides calcium and protein.
   • Choose low-fat milk, yogurt, and cheese.
4. Incorporate lean protein
   • Opt for lean meats, poultry, and fish (2 or fewer servings of lean meat per day).
   • Include plant-based proteins like beans, lentils, tofu, and nuts.
5. Limit sodium intake
   • The standard DASH plan recommends no more than 2,300 mg of sodium daily.
   • For even better results, reduce sodium to 1,500 mg per day, especially if you already have high blood pressure.
   • Tips: Use herbs, lemon, and spices instead of salt to flavour food.
6. Cut back on saturated fats and sweets
   • Minimise foods high in saturated fat (e.g., fatty meats, butter, full- fat dairy).
   • Limit sweets to no more than 5 servings per week.
   • Examples: soda, candy, pastries, sugary cereals.
7. Add nuts, seeds, and legumes
   • These provide healthy fats, magnesium, and fibre.
   • Recommended: 4-5 servings per week.
   • Examples: almonds, sunflower seeds, kidney beans, lentils.

2. Stay active

How exercise helps Lower Blood Pressure

• Strengthens the heart, reducing the effort it needs to pump blood.
• Improves blood vessel flexibility, allowing better circulation.
• Aids in weight loss, which directly reduces blood pressure.
• Lowers stress hormones, such as adrenaline and cortisol.

Recommended types of physical activity for hypertension

1. Aerobic exercise (Cardio)
   • Best for lowering blood pressure
   • Aim for 30-60 minutes per day, at least 5 days a week Activities include:
     • Brisk walking
     • Jogging or cycling
     • Swimming
     • Dancing
2. Strength training (resistance exercise)
   • Helps build lean muscle mass and supports metabolism.
   • Aim for 2-3 sessions per week, working all major muscle groups.
   • Bodyweight exercises (squats, lunges, push-ups).
3. Flexibility and balance training
   • Helps with overall fitness and injury prevention
   • Include stretching or yoga 2-3 times per week
   • Yoga and tai chi ( a gentle form of exercise and meditation which involves a series of slow, flowing movements combined with deep breathing and mental focus) also reduce stress and aid blood pressure control

Tips for getting started safely

• Start slow if you're new to exercise- begin with 10-15 minutes a day and gradually build up.
• Warm up and cool down with gentle stretching or walking.
• Stay hydrated and avoid exercising in extreme heat.
• Monitor how you feel: stop if you experience chest pain, dizziness, or extreme shortness of breath.
• Check with your doctor before starting a new routine, especially if you have heart conditions or other medical issues.

3. Maintain a healthy weight

Carrying extra weight puts strain on your heart and blood vessels. Losing even 5-10% of your body weight can significantly reduce blood pressure levels.

• Combine diet changes with physical activity for best results.
• Focus on gradual, sustainable weight loss rather than quick fixes.

4. Reduce stress

Chronic stress may contribute to high blood pressure. While we can't always eliminate stress, we can learn healthier ways to manage it:

• Practice deep breathing, meditation, or yoga
• Spend time in nature or with supportive people
• Prioritise adequate sleep

5. Limit Alcohol and Avoid Smoking

• Alcohol: Limit to no more than one drink per day for women and two for men.
• Smoking: If you smoke, seek help to quit. Every cigarette increases your blood pressure temporarily-and long-term use damages your arteries.

6. Monitor Your Blood Pressure at Home

Keeping track of your blood pressure helps you understand how lifestyle changes are working.

Here are some tips to monitor your blood pressure at home:

1. Use a Validated Monitor
   • Use an automatic, upper-arm blood pressure monitor approved by the British and Irish Hypertension Society (BIHS).
2. Prepare properly
   • Rest for 5 minutes before measuring.
   • Sit upright, with your back supported, feet flat on the floor, and arm at heart level.
   • Avoid caffeine, smoking, or exercise for 30 minutes beforehand.
3. Position the cuff correctly
   • Place the cuff on bare skin above the elbow.
   • Ensure it's snug but not too tight-you should be able to fit one finger under it.
   • The tubing should run down the front centre of the arm
4. Take the reading
   • Press the start button and let the monitor inflate and deflate automatically while staying still
   • Note the systolic and diastolic numbers
   • Some monitors also give your heart rate (pulse)
5. Take two readings
   • Wait 1-2 minutes between readings.
   • If the two readings are very different, take a third and average the last two.
6. Record your results
   • Keep a log of your readings: date, time, and numbers.
   • The NHS recommends checking twice each morning and evening for 7 days, then sharing the average with your GP.

Managing high blood pressure doesn't have to mean a lifetime of medications. With the right strategies, many people can naturally control their blood pressure and lower their risk of serious complications like heart disease and stroke.
