Researchers have found, for instance, that drinking tea lowers levels of the stress hormone cortisol. And evidence of long-term health benefits is emerging, too: drinking at least 100 millilitres (about half a cup) of green tea a day seems to lower the risk of developing depression and dementia.
What kind of tea reduces cortisol?
Research from 2014 shows that some herbal teas — in particular, Melissa officinalis, or lemon balm extract — can lower levels of cortisol, the stress hormone, in the body. A 2018 study suggests that even just inhaling tea aroma — black tea, specifically — can help lower stress levels and produce a calmer mood.
Research study shows that drinking five or more cups of green tea on a daily basis may reduce the incidence of psychological distress by up to 20 percent. Drinking green tea lowers levels of the stress hormone called cortisol.
