High blood pressure, or hypertension, affects more than one in four UK adults, according to the NHS.
Symptoms are usually difficult to spot, unless your blood pressure is extremely high.
Finding blood in your urine, or having severe headaches, vision problems and a pounding in your chest, could all be signs of high blood pressure.
But, you could lower your blood pressure by cutting back on coffee and tea.
Meanwhile, eating avocados could help to lower your risk of high blood pressure, it’s been revealed.
They contain healthy fats, that may help to deal with high blood pressure.
Nuts, seeds, coconut oil and extra virgin olive oil also contain healthy fats.
But, eating too many avocados increases your risk of obesity, as just one half of an avocado contains up to 200 calories.
“It’s not always clear what causes high blood pressure, but certain things can increase your risk,” said the NHS.
“Drinking more than four cups of coffee a day may increase your blood pressure.
“If you’re a big fan of coffee, tea or other caffeine-rich drinks, such as cola and some energy drinks, consider cutting down.
“It’s fine to drink tea and coffee as part of a balanced diet, but it’s important that these drinks are not your main or only source of fluid.” Caffeine’s effect on blood pressure varies from person to person.
If you’re more caffeine-sensitive, coffee could raise your blood pressure more than others.
Getting a good night’s sleep could also help to lower your blood pressure, the NHS added.
Long-term sleep deprivation is linked to a rise in blood pressure, so it’s a good idea to get at least six hours of sleep every night.
Being overweight or obese makes it harder for your heart to pump blood around the body, which increases blood pressure.
Losing just a few pounds will make a big difference to blood pressure.
Having high blood pressure puts extra strain on your blood vessels, and vital organs.
Hypertension increases the risk of heart disease, strokes, and vascular dementia.
The only way of finding out if you have hypertension is to get your blood pressure checked.
Some pharmacies and your GP can check your blood pressure for you.
