Used as a medicinal drink for thousands of years across Asia, the health benefits of green tea have long been recognised.  These benefits aren’t just an old wives’ tale though. There is some interesting science behind the ideas. Here are 5 of the most interesting health benefits that drinking green tea can provide.

It boosts your metabolism

Some studies have shown that green tea can actually help to increase your metabolism: the rate at which your body processes energy and burns fat. This means that drinking green tea could potentially help you to lose weight, if you’re following a healthy lifestyle and taking regular exercise.

It contains beneficial antioxidants

It’s been proven that certain types of green tea contain powerful, natural antioxidants known as catechins. These can have a range of beneficial effects on your health. Antioxidants are molecules that prevent damage to your cells. Because green tea isn’t processed and fermented, it’s naturally rich in catechins.

It can improve the oral health

The natural chemicals in green tea have been found to kill harmful bacteria in your mouth in some cases. This may help to reduce the risk of damage to your teeth from decay or gum disease. That said though, don’t rely on just green tea to keep your teeth health—use it as a supplement with regular brushing and flossing!

It can potentially lower your blood pressure

There is some evidence that green tea can help to lower your blood pressure and cholesterol levels. Thanks to its high levels of antioxidant catechins, green tea can keep the level of sugar in your blood stable, potentially helping to reduce your overall blood pressure and cholesterol.

It can help you relax and destress

Perhaps the health benefit that most people drink it for, green tea has been proven to help you relax. This is due to the presence of theanine—a natural amino acid— found in green tea leaves. Scientists have shown that theanine can have a calming effect on your mind, reducing stress and anxiety in some cases and helping you to relax.
