Understanding Blood Pressure and CBD
Managing cardiovascular health is a priority for many, especially with the rising prevalence of hypertension. Blood pressure is measured using two numbers: systolic and diastolic. Systolic pressure, the higher number, reflects the force of blood against artery walls during a heartbeat. Diastolic pressure, the lower number, measures the same force when the heart is at rest. A healthy reading is typically below 120/80 mmHg.
Hypertension is categorized into two types: primary and secondary. Primary hypertension develops gradually and is often linked to genetics, age, or lifestyle. Secondary hypertension, on the other hand, arises suddenly due to underlying conditions like kidney disease or hormonal imbalances. Addressing the root cause can often resolve secondary hypertension.
What Is High Blood Pressure?
High blood pressure, or hypertension, occurs when the force of blood against artery walls is consistently too high. This condition can strain the heart and damage blood vessels, increasing the risk of serious health issues. The World Health Organization estimates that over 1 billion people worldwide are affected by hypertension, making it a global health concern.
