Study Notes
Blood Pressure
Blood pressure is the force exerted by the blood against the walls of the arteries as the heart pumps blood throughout the body. It is measured in millimeters of mercury (mm Hg) and is typically expressed as systolic pressure (the pressure when the heart beats) over diastolic pressure (the pressure when the heart rests between beats). Normal blood pressure is considered to be 120/80 mm Hg, but this can vary based on age and other factors.
Systolic Blood Pressure
Systolic blood pressure is the pressure inside the arteries when the heart contracts, pushing blood through the body. It is the higher number in the blood pressure reading. Elevated systolic blood pressure, known as hypertension, can cause damage to the blood vessels and lead to heart disease and stroke.
Diastolic Blood Pressure
Diastolic blood pressure is the pressure inside the arteries when the heart is at rest between beats. It is the lower number in the blood pressure reading. Low blood pressure can cause dizziness or fainting, especially if it drops suddenly.
Factors Affecting Blood Pressure
Several factors can affect blood pressure, including genetics, lifestyle, and environmental factors. Some of these factors include:
- Genetics: Certain genetic variations can increase the risk of developing high blood pressure (Webb et al., 2008).
- Diet: A diet high in sodium and saturated fats can lead to increased blood pressure (AHA, 2013).
- Exercise: Regular physical activity can help lower blood pressure (AHA, 2013).
- Weight: Obesity can contribute to high blood pressure (AHA, 2013).
- Age: Blood pressure generally increases with age (AHA, 2013).
- Stress: Chronic stress can lead to increased blood pressure (AHA, 2013).
Lowering Blood Pressure
There are several approaches to lowering blood pressure, including medication, dietary changes, and lifestyle modifications. Some effective methods include:
- Medication: Prescription medications, such as ACE inhibitors and beta-blockers, can help lower blood pressure (AHA, 2013).
- Diet: Reducing salt intake and increasing the consumption of fruits, vegetables, and whole grains can help lower blood pressure (AHA, 2013).
- Exercise: Regular physical activity can help lower blood pressure (AHA, 2013).
- Weight loss: Losing weight can help lower blood pressure, especially in overweight or obese individuals (AHA, 2013).
- Stress reduction: Techniques such as meditation, yoga, and deep breathing can help lower blood pressure (AHA, 2013).
Conclusion
Understanding blood pressure and its factors is crucial for maintaining cardiovascular health. By being aware of the factors that can affect blood pressure and taking steps to lower it when necessary, individuals can reduce their risk of developing heart disease and stroke.
