High blood pressure affects more than 25 per cent of all UK adults, according to the NHS.
The condition, which is also known as hypertension, increases the risk of some deadly complications, including heart attacks, heart disease and strokes.
Making some small dietary changes could help to prevent signs of high blood pressure.
Drinking a mug of hibiscus tea could help to lower your blood pressure, scientists have claimed.
Drinking hibiscus tea before eating breakfast could lower both patients’ systolic and diastolic blood pressure, according to scientists in Mexico.
The tea may lower blood pressure by as much as 15/11mmHg, they claimed.
The best type of hibiscus tea is that made from Hibiscus sabdariffa, added biochemist Dr David Williams.
“If you have high blood pressure, your diet is one of the primary ways by which you can lower your blood pressure numbers without medication,” he said.
“Combined with appropriate lifestyle changes and targeted nutritional support, changing your diet can not only reduce your blood pressure numbers, but significantly improve your overall cardiovascular health.
“Hibiscus tea has been a traditional remedy for high blood pressure in Iran and other countries around the world.
“However, this remedy is one that must be used continuously to maintain its positive results.”
When patients stop drinking hibiscus tea for just three days, their blood pressure could increase again, warned Williams.
You could also lower your blood pressure by eating more celery, he added.
Celery contains a chemical that smoothes the muscles lining the blood vessels, while also allowing blood to flow easier, he said.
A daily cup (110g) of celery could be enough to lower your blood pressure.
High blood pressure rarely has noticeable symptoms, said the NHS. The only way to reveal whether you’re at risk of hypertension is to get it checked.
If you have extremely high blood pressure, some patients may have headaches, chest pain or find blood in their urine.
People eating an unhealthy diet or leading a sedentary lifestyle are most at risk of hypertension.
All UK adults over 40 years old should check their blood pressure at least every five years.
Speak to a GP or pharmacist to have your blood pressure checked.
