High blood pressure affects about 16 million people in the UK, and many people won’t realise they have it, according to the NHS.
The only way to find out if you have high blood pressure is to get it checked.
Having hypertension puts extra strain on your blood vessels, heart and other vital organs.
But, you could lower your risk of high blood pressure by taking fish oil supplements everyday.
“A type of fat called omega-3 fatty acids is found in fatty fish like mackerel and salmon,” said medical website WebMD.
“Large amounts of fish oils may help reduce high blood pressure, but their role in prevention is unclear.”
Nutritionist Dr Josh Axe added: “One of the main causes of high blood pressure is inflammation in the arteries over time.
“Taking a high quality, 1,000mg fish oil dose every single day with your meals is one of the best natural ways to lower blood pressure.”
You could also lower your blood pressure by eating a Mediterranean-style diet.
The diet is rich in fruit, vegetables and seafood, which are packed full of omega-3 fatty acids.
Potassium helps to protect against the effects of sodium, so eating more potassium-rich foods could help to lower your blood pressure.
Bananas and coconut water are both great sources of the essential element.
A blood pressure reading between 120/80mmHg and 140/90mmHg means you could have hypertension, the NHS said.
High blood pressure increases the risk of heart disease, heart attacks and strokes.
All adults over 40 should get their blood pressure checked every five years.
Your local GP and some pharmacies can check your blood pressure.
