On World Hypertension Day, we’re reminded that high blood pressure—often known as the “silent killer”—can quietly damage the body without causing any obvious symptoms. While many are aware that an unhealthy diet, lack of exercise, and obesity contribute to high blood pressure, other lesser-known culprits could be quietly pushing your numbers up.
We spoke with Dr T. S. Kler, Chairman and head of the department at BLK-Max Heart and Vascular Institute, to understand some surprising triggers behind rising blood pressure and why awareness is key.
“Many people associate high blood pressure with diet and age, but there are other silent factors that often go unnoticed and untreated. Addressing these can make a big difference,” says Dr Kler.
Here are 7 such hidden reasons you should be aware of:
1. Chronic Stress
Daily stress isn’t just exhausting—it can be harmful to your heart too.
“When you're under constant stress, your body releases hormones like cortisol and adrenaline. These narrow your blood vessels, pushing up your blood pressure over time,” explains Dr Kler.
“Stress also drives people toward unhealthy habits like smoking or junk food, which only worsen the issue.”
2. Sleep Disorders Like Sleep Apnea
Snoring loudly at night? It might be more than just annoying for your partner.
“Sleep apnea, where breathing stops and starts during sleep, drops oxygen levels and spikes blood pressure. If you feel tired even after a full night's sleep, it’s worth getting evaluated,” warns Dr Kler.
3. Hidden Salt in Processed Foods
You may not be shaking the salt shaker, but that doesn’t mean your diet is low in sodium.
“Packaged foods like soups, cold cuts, breads, and snacks are loaded with hidden salt. Even so-called ‘healthy’ items can have high sodium,” notes Dr Kler.
“Reading nutrition labels is essential.”
4. Medication Side Effects
Some commonly used medications can sneakily affect your blood pressure.
“Over-the-counter painkillers like ibuprofen, decongestants, antidepressants, and even birth control pills can raise blood pressure,” says Dr Kler. “Always review your medications with your doctor, especially if your BP remains high despite treatment.”
5. Alcohol ConsumptionThat nightly glass of wine may not be as heart-friendly as you think.
“Alcohol raises blood pressure, especially in excess. It can also interfere with the effectiveness of your medication,” warns Dr Kler.
“Stick to recommended limits: one drink per day for women, two for men.”
6. Low Potassium Intake
Potassium helps balance out the effects of sodium. Without enough, your BP can rise.
“A diet low in fruits and vegetables often means low potassium. Bananas, spinach, and sweet potatoes are great sources,” suggests Dr Kler.
7. Loneliness and Isolation
Your mental well-being plays a bigger role than you may think.
“Loneliness can lead to chronic stress, and that, in turn, can elevate blood pressure. Staying socially connected supports better heart health,” Dr Kler explains.
High blood pressure isn’t just about one bad habit—it’s a combination of lifestyle, hidden triggers, and even emotional health.
“Medication helps, but addressing these hidden causes is just as important. A holistic, informed approach to hypertension can save lives,” shares Dr Kler.
