A recent study found encouraging results that tea consumption boosts your brain connectivity. The study was based on a small population of people who drink tea regularly and those who rarely drink tea.
For many people, it a common belief that tea can heal their illness, it is challenging to find relative evidence. This is particularly true when tea consumption is related to brain health.
Till now, researchers have found no significant evidence regarding tea benefit on mental health. However, certain studies have found associations between tea consumption and mental health.
A study found that elderly who drink tea regularly did not commonly show depression-related symptoms.
Another study conducted back in 2008 included 2,501 individuals who drank tea regularly. The study concluded that tea consumption on a regular basis was linked with reduced risk of cognitive impairments.
In another study, the researchers included only 58 participants. Their main focus was to identify more cognitive benefits of drinking tea. They concluded that drinking black tea increases your attention and alert capabilities.
Effect of tea on lines of communication in the human brain
In the most recent study, researchers from the National University of Singapore focused on a different approach. They tried to access brain connectivity with regional and global metrics which are derived from structural and functional imaging.
Researchers wanted to discover whether the lines of communication within the brain of tea consumers were more organized or not. They particularly focused on brain connectivity in the default mode network (DMN).
DMN basically connects a large number of brain regions. It plays a key role in developing a sense of oneself, moral reasoning, imagining the future and empathy.
Some scientists also believe that DMN plays a role in brain aging and some neurological conditions.
They also investigated hemispheric asymmetry. It means that the lines of communication are not evenly spread on either side of the brain.
The researchers selected only 36 adults with age 60 years and above. They collected data from the participants regarding their psychological well-being, overall health, and lifestyle.
They asked all the participants to get an MRI scan. Later, the researchers let them go through their psychological paces with a series of tests.
The participants were divided into two groups. One group included 15 tea drinkers while the other group contained 21 non-tea drinkers.
The researchers compared the results of the neuropsychological and cognitive measurements of both groups. They found no significant difference.
However, when they compared the brain connectivity between the two groups, they found some differences.
The result showed that the tea drinkers had more structural and functional connectivity than non-tea drinkers. This was due to increased DMN efficiency.
The study is just the beginning of shreds of evidence
Professor Fung Lei said when the connections in the brain are more organized, the information can be processed more efficiently.
Since the study was observational, it is possible that some other factors may create differences in results. Moreover, the study was based on a small population. Thus, we cannot completely rely on the observed findings.
For instance, in a social person, the significant social life and conversations are enough to make his brain function more efficiently.
Although the recent study had a hi-tech approach, researchers need to work more regarding brain connectivity and efficiency.
