What is Blood Pressure?

Understanding Blood Pressure: Readings & Care Tips

Blood pressure is defined as the force of blood against the walls of the arteries while the heart pumps blood throughout the body. It is an important health metric that provides insights about cardiac and overall well-being. 

Blood pressure can vary due to physical activity, stress, sleep, posture, caffeine intake, and time of day. Thus, you must know what it is and how it is measured. Read ahead to understand more about blood pressure readings and their implications. 

What do Blood Pressure Readings Mean?  

The blood pressure readings appear as two numbers separated by a / in units of millimeters of mercury (mm Hg), such as 130/90. The numbers at the top and bottom of a blood pressure reading represent the following: 

• Systolic pressure: The number above the / (130) describes systolic pressure. It is the pressure in the arteries when the heart contracts and pumps blood. 
• Diastolic pressure: The number below / (90 is the diastolic pressure. It represents the pressure in the arteries when the heart relaxes between beats. 

How to Measure Blood Pressure?   

The blood pressure is measured through a sphygmomanometer. If measured manually, the medical professional will follow these steps: 

• Step 1: The cuff connected to the gauge will be wrapped around your arm above the elbow.   
• Step 2: Squeeze the ball attached to the gauge to inflate the cuff and secure it around your arm. Applying pressure firmly temporarily halts blood circulation in the brachial artery. At this point, the gauge should show a reading of 200 mm Hg.   
• Step 3: The cuff is deflated by loosening the attached valve, and a stethoscope is used to listen to the blood flowing through the brachial artery. Upon deflation, the gauge needle falls down. 
• Step 4: The gauge reading is noted when the pulse starts again. This is recorded as the systolic pressure. The valve is opened to loosen the pressure, so the blood starts flowing again through the brachial artery. 
• Step 5: The diastolic pressure is recorded when the Korotkoff sounds disappear completely as the cuff pressure continues to fall. 

You can also use a digital blood pressure monitor to automatically check your blood pressure anytime.   

What do Different Blood Pressure Ranges Represent?  

Oftentimes, 120/80 mm Hg is considered the normal blood pressure reading for most people. However, it can differ depending on their medical background. Here is a guide on blood pressure ranges: 

Blood pressure below 90/60 mm Hg may be considered low, particularly if it causes symptoms such as dizziness or fainting. It can make you feel dizzy and sometimes negatively impact your health. High blood pressure can lead to potential cardiac complications like a heart attack or stroke. 

However, it doesn’t show any notable symptoms. The only way to determine if you have high blood pressure is to consistently check your blood pressure levels.    

What Factors Contribute to Blood Pressure?  

The following are some common factors that can contribute to high blood pressure: 

1. Genetics and Age: A positive family history of high blood pressure and increasing age are non-modifiable risk factors. 
2. Consuming too much salt: Excessive salt in the body, combined with low dietary potassium, can also increase the risk of high blood pressure. 
3. Being Overweight: Excess body weight or obesity can cause high blood pressure. 
4. Alcohol and Smoking:  Smoking, chewing tobacco or vaping can raise blood pressure immediately. 
5. Lack of Exercise: Physical inactivity is associated with blood pressure. Maintaining a healthy weight is essential to staying healthy.   
6. Excessive alcohol consumption: Drinking too much alcohol is associated with blood pressure. 
7. Stress: Stress can cause short-term increases in blood pressure and may indirectly contribute to long-term hypertension through lifestyle factors.    
8. Other Medical Conditions: Some health problems, like thyroid, diabetes, and kidney problems, can lead to high blood pressure. 

What are the Tips to Manage Blood Pressure Levels? 

Lifestyle modifications are essential to managing blood pressure levels. However, if you have a persistent high blood pressure profile, your doctor may prescribe certain medications to manage your blood pressure. 

Here are a few tips to effectively manage blood pressure levels: 

• Avoid smoking completely. Use nicotine gum to fight off addiction effectively. 
• Follow a heart-friendly diet loaded with fruits, vegetables, and whole grains. 
• Reduce the intake of salt in your meals. Add other herbs and spices to enhance the flavor of food. 
• Follow a regular exercise routine combining cardio, muscle training, and breathing exercises. 
• Limit alcohol intake in line with medical advice, generally not exceeding one drink per day for women and two drinks per day for men. 
• Maintain a healthy body weight. You can achieve this by following a fat-loss diet and regular exercise. 

Blood pressure can increase with age, so it is essential to build healthy habits to manage it effectively. This requires a long-term commitment to a multifaceted approach, which can be achieved through a balanced diet, an exercise routine, and stress management techniques.
