As we all know, drinking tea can refresh the mind, and the benefits of tea to the brain are more than that. A new study finds that regular tea drinkers have healthier brain structures in old age, helping to slow down cognitive decline. A team of international research teams led by the US recently published in the American Journal of aging that the ingredients in tea can directly affect the connections between the brain regions. Regular tea drinking helps the brain resist structural changes caused by age.
A team of 36 people over the age of 60, collected information on their physical status, lifestyle and mental health from 2015 to 2018. Neuropsychological tests and magnetic resonance imaging were performed on them. By analyzing their cognitive performance and imaging results, researchers found that people who drank tea at least 4 times a week for 25 years had higher brain connectivity than those who did not drink tea, whether green tea, oolong tea or black tea. Researchers explain that when road traffic is well planned, vehicles and pedestrians travel more efficiently, and when brain regions are better connected, the brain processes information more efficiently. The team found in 2017 that drinking tea every day reduces the risk of cognitive decline by 50% in old age. This study further confirms this conclusion. Researchers say that the brain of tea drinkers can avoid interference with ineffective connections and help slow down cognitive decline.
