Cold plunging has become a popular wellness practice for its ability to activate thermogenesis—the body’s natural heat-producing process that helps boost metabolism and burn fat. Interestingly, several scientific studies have shown that green tea extract can trigger a similar thermogenic response, but from the inside out.

Research published in journals such as the American Journal of Clinical Nutrition has reported that compounds in green tea, especially EGCG (epigallocatechin gallate) combined with naturally occurring caffeine, can modestly increase energy expenditure and fat oxidation through thermogenesis. In simpler terms, both cold exposure and green tea extract encourage the body to use stored fat as fuel—yet one does it through a shiver, and the other through a sip.

While greenteaHAWAII makes no medical claims and was not involved in these studies, we’ve intentionally formulated our beverages with green tea extract and L-theanine to help support clean, balanced energy—offering a refreshing way to feel good without the chill.
