Population studies suggest that drinking three or more cups of green tea daily is linked to a decreased risk of death from heart disease or any cause.
Very few long-term studies have investigated the effects of tea on heart disease risk.
But there is evidence that suggests that green tea might have beneficial effects on some heart disease risk factors, including blood pressure and cholesterol
The free radicals created in the body are responsible for corroding the body in various ways, one of which we see as the signs of aging and its related symptoms. Antioxidant-rich green tea neutralizes the oxidants or free radicals present in the body.
Green tea is chock full of Vitamin B2 and Vitamin E, both essential for skin health maintenance. B2 plays an essential role in maintaining collagen levels for youthful skin structure and firmness.

In a preliminary study published in February 2010 in Cancer Prevention Research, mice exposed to green tea polyphenols in drinking water showed better skin cell repair after UV ray damage, though it’s not yet clear if this same effect would be observed in humans
The antioxidants in green tea, specifically the catechin EGCG has shown benefits for reducing metastasis and improving outcomes for cancers of the breasts, lungs, colon, skin, and others.
