The ability to think normally reduced when the body is feeling tired. But with a cup of tea, the brain is still guaranteed to be invited to think hard though the body in a state of tired and do not have the energy for physical activity.

Compared to coffee that only rely on caffeine as a booster fitness, teas have other content that is compound L-theanin. This compound is an amino acid that is able to increase their vigilance and ensure that the brain is always awake in any seletih condition.

Simply by sipping a cup of tea, L-theanin effects could be felt during the next 20 to 70 minutes. Concentration stay awake, the mind can still be relied upon even though the physical body is not able to do strenuous activity.

Dutch researchers have proved this through a study published recently in the journal Nutritional Neuroscience. In that study, researchers used various types of tea including green tea and involved 44 volunteers aged less than 40 years.

The combination of L-theanin and caffeine in a cup of tea proven to improve the accuracy of counting the volunteers, and reduce drowsiness. Similar effects are not found in other groups who were given only a placebo in the form of other beverages that do not contain two compounds.

“Our results indicate that the combination of L-theanin and caffeine bsia maintain cognitive ability or the ability of the brain to think,” wrote the researchers in its publication.

The researchers also said the benefits of tea will not be reduced by adding a little milk to variations in the presentation. Milk does not inhibit the absorption of flavonoids and antioxidants and other compounds that are useful in a cup of tea.

In addition to maintaining brain function during fatigue, other benefits of drinking tea has also been frequently demonstrated in various studies. Among them are able to increase bone density and reduce the risk of cancer, heart attacks and Parkinson’s.
