A cup of tea is a morning ritual for many people around the world.
So, here’s some good news for those who can’t do without their daily brew – researchers have discovered that habitual tea drinking modulates brain efficiency.
For their study, Dr. Junhua Li and Dr. Lei Feng recruited healthy older participants and split them into two groups according to their history of tea drinking.
They then investigated both functional and structural networks to understand the role of tea drinking on brain organisation, and as a result, observed the suppression of hemispheric asymmetry in the structural connectivity network. The authors did not observe any significant effects of tea drinking on the hemispheric asymmetry of the functional connectivity network.
“In summary, our study comprehensively investigated the effects of tea drinking on brain connectivity at both global and regional scales using multi-modal imaging data and provided the first compelling evidence that tea drinking positively contributes to brain structure making network organisation more efficient,” they commented.
The researchers also noted that the majority of studies to date have evaluated tea effects from the perspective of neurocognitive and neuropsychological measures and direct measurement of brain structure or function aren’t as well represented in literature.
Meanwhile, in another study published last month, experts found that individuals who consumed either green tea, oolong tea, or black tea at least four times a week for about 25 years had brain regions that were interconnected in a more efficient way.
Full study results have been published in the journal, Aging.
