According to the Centers for Disease Control and Prevention (CDC),

seasonal influenza information and prevention guidelines from the CDC
,
flu activity in the United States typically peaks in January or February.

The severity of each flu season can vary, and while some years are milder than others, the CDC continues to recommend annual vaccination as the most effective way to protect against the virus.

Tea drinkers, however, may benefit from additional support due to naturally occurring compounds found in tea, particularly catechins and theanine.

The relationship between tea and influenza has been examined in

this research study investigating green tea consumption and influenza incidence in children
,
conducted by researchers at the University of Shizuoka in Japan and published in the Journal of Nutrition.

While earlier research had focused on adults, this study specifically examined school-aged children, analyzing data from approximately 2,600 participants living in tea-growing regions of Japan.

The findings suggested that children who consumed green tea regularly—particularly those drinking five or more cups per week—experienced fewer cases of influenza and fewer absences from school compared to those who drank little or no tea.

Researchers attributed these effects to catechins, which may interfere with viral mechanisms, and to the combined influence of catechins and theanine in supporting immune function.

Theanine, a compound also associated with relaxation and reduced stress, is explored further in
