How does green tea help in controlling high blood pressure?
Green tea and its role in reducing high blood pressure is backed by science.
There are pieces of evidence that show the effectiveness of the beverage in helping the blood vessels relax.
The reason behind this effect is the polyphenol content of green tea.
The polyphenol EGCG (or Epigallocatechin Gallate) in green tea helps in lowering high blood pressure. It does this by ensuring the elasticity of your blood vessels so that blood flows properly through them.
It also works towards preventing the formation of deposits in your arteries. As a result, the BP stays normal.
Other kinds of polyphenols present in green tea help in maintaining the right levels of bad cholesterol (LDL) in the blood so that the arteries don’t get clogged up!
Polyphenols also help in reducing the production of angiotensin in the body. It is a hormone that raises the BP of the body.
Overall, polyphenols have a pivotal role to play in improving the pumping function of the heart and regulating blood flow for good cardiovascular health.
Additionally, it has been found that consuming green tea reduces your total cholesterol levels and LDL (bad cholesterol levels).
It is LDL that blocks your blood vessels and increases the chances of a heart attack. Therefore, it is important to keep your LDL levels in check.
In order to reap the blood-pressure-lowering benefits of green tea, studies indicate that you need to consume 5 to 6 cups a day.
However, the consumption of the beverage should not be more than this, or else it can lead to adverse effects.
Can you drink green tea if you have low blood pressure?
A lot of people suffer from low blood pressure. The condition can make you feel dizzy without a warning. It occurs only because the amount of blood flowing to your head is not sufficient.
Mild cases of low blood pressure or hypotension can be easily dealt with using simple home remedies.
Sipping on green tea is one great way to get your low blood pressure back to normal. A single cup of green tea has 25 mg of caffeine that works really well in enhancing your body’s blood flow.
However, it is best advised to consume the tea within limits.
Does green tea harm or affect those on blood pressure medicine?
Those who are consuming high blood pressure medicines need to be a little wary while consuming green tea.
According to research conducted by the Japanese, it has been found that green tea can block the effects of nadolol, which is one of the most commonly prescribed drugs to high BP patients.
Green tea renders the drug less effective by not letting it completely get into the bloodstream.
However, this fact does not make green tea unhealthy. It has a number of other health benefits to offer.
To resolve the issue of the interaction of green tea with nadolol, it is suggested that high blood pressure patients leave a gap of 4 hours between their medicine intake and green tea consumption.
Does the caffeine in green tea constrict blood vessels?
No! In fact, green tea helps in keeping the arteries relaxed and supple so that there is no problem when there are changes in blood pressure.
A study indicates that green tea is capable of helping vessels relax.
Green tea makes the cells on the lining of the blood vessels secrete chemicals that facilitate the relaxation of the vessels.
The flavonoids in green tea are the antioxidants that ensure the flexibility of the blood vessels. They also have a role to play in preventing the formation of blood clots.
Final Thoughts
Green tea, ample exercise, and a healthy diet have to be a part of your lifestyle if you are suffering from high BP.
However, if you are already on medication for high blood pressure, it is best advised that you talk to your doctor regarding green tea consumption.
This is important because green tea has an effect on medicines meant for high BP patients.
