Green tea has a powerful effect on your mind.
Green tea has many health benefits and can also make you happier.
Previous studies have shown positive effects of green tea, such as reducing the risk of heart disease and stroke. Okinawans have lower rates of cancer, heart disease and dementia than Americans, and women there live longer than anywhere else on the planet. Many believe the Okinawan diet contributes to their longevity, with jasmine tea being a popular drink.
Additionally, scientists say green tea can improve mood.

“The bioactives in green tea help the mind stay focused and relaxed. It is no exaggeration to say that this tea contributes to the happiness of the people of Okinawa. Locals often enjoy jasmine green tea,” said Maggie Moon, brain health nutrition expert and bestselling author ofMIND Diet,tellWell + Good.
The main components of green tea include caffeine, theanine, arginine, and EGCG, explains Moon, of which EGCG is the most active and the most studied phytochemical.
The combination of these bioactive ingredients can enhance mood during the day and long term as well as have anti-inflammatory, longevity potential.
A 2018 study found that people who consumed at least three cups of green tea per week had a 21% lower risk of depression than those who did not.
“Green tea is culturally associated with moments of stillness. The caffeine and L-theanine combine to create a calm, yet alert state of mind,” explains Moon. The caffeine content in green tea is lower than in coffee, so it’s less likely to cause jitters, while the L-theanine reduces stress.
According to a 2017 review, combining stimulants with amino acids has been shown to reduce anxiety, improve brain function, and enhance memory and attention. Green tea’s anti-inflammatory properties are another reason to enjoy a cup. A 2023 meta-analysis found that people who followed an anti-inflammatory diet had a 29% lower risk of depression.
Flavonoids in green tea promote the growth of new brain cells and keep existing brain cells healthy. Flavonoids suppress inflammation in the brain and counteract the negative effects of stress.
You can reap the benefits of green tea whether you drink it a few times a week or a few times a day. If you drink it daily, be aware that too much caffeine can cause restlessness and insomnia at night.
However, according toNew York Post, a study in October 2023 found that adults who consumed more caffeinated beverages had significantly better physical health.
“Coffee and tea are staple beverages in many parts of the world, including Singapore. Our study shows that consuming caffeinated beverages in middle age may reduce the risk of physical frailty in old age,” said Professor Koh Woon Puay (National University of Singapore), who led the study.
