Hypertension: Understanding the Silent Killer
The World Health Organization (WHO) estimates that 1.28 billion adults worldwide have hypertension, yet nearly half are unaware of it. Because high blood pressure often has no symptoms, it is crucial to have regular check-ups.
The Impact of High Pressure
Persistent high blood pressure damages the lining of the arteries, making them less elastic. This restricts blood flow throughout the body and forces the heart to work harder, eventually leading to heart failure or stroke.
Strategies for Control:
- The DASH Diet: High in fruits, vegetables, and lean protein; low in salt.
- Salt Reduction: Aim for less than 5g of salt (1 teaspoon) per day.
- Consistency: Regular, moderate exercise like brisk walking is more effective than occasional high-intensity training.
