Tea & Brain Health
Along with being a great productivity booster, tea also shows promise for long-term cognitive improvement. A study in Singapore compared the brains of people who drank green, oolong, or black tea at least four times a week for at least 25 years with the brains of non-tea drinkers. They found that the brain regions of tea drinkers were interconnected in a more efficient way than non-tea drinkers, even when adjusting for lifestyle and general health.
To illustrate the significance of this result, Assistant Professor Feng Lei, the team leader of the study, compared the paths of the brain to roads. “When a road system is better organized, the movement of vehicles and passengers is more efficient and uses less resources. Similarly, when the connections between brain regions are more structured, information processing can be performed more efficiently," he explained.
Some herbal teas have also shown promise in improving brain health.
Power Couple: L-Theanine + Caffeine
Any tea made from the Camellia sinensis, which includes all black, green, oolong, and white teas, contains an amino acid called l-theanine. On its own, l-theanine can reduce stress and anxiety, but combined with tea’s caffeine, can improve brain function. Several studies have found that the combination of caffeine and l-theanine is more effective than caffeine alone in increasing subjects’ self-reported alertness and energy, as well as improving performance during demanding cognitive tasks. So when you're trying to stay focused for a long work or study session, a cup of tea will be more effective than an energy drink or iced coffee any day!
Improved cognitive function isn’t the only benefit of the combination of l-theanine and caffeine, though. Research shows that along with boosting caffeine’s best effects, l-theanine can also decrease caffeine’s unwanted effects. L-theanine mitigates caffeine’s interaction with the brain and can prevent the jitters and crash that some experience when consuming caffeine alone.
The amounts of l-theanine in a cup of tea can vary significantly, but green tea tends to have the most. Matcha stands out as the type of tea with the most l-theanine; up to five times more than regular green tea. The tea leaves used to make matcha are grown in the shade, which enhances the l-theanine content.
