Tea Reduces Stress and Lowers Cortisol

Stressed out? Reach for a soothing cup of black tea.

A recent study conducted by University College London researchers evaluated the effects of black tea on stress in the body.

Tea Reduces Stress, Lowers Cortisol and Boosts Relaxation

In the study, 75 regular tea drinkers were split into two groups. All study participants gave up their normal tea, coffee and caffeinated beverages. One group was given a caffeinated tea mixture made up of the constituents of an average cup of black tea. The control group was given a caffeinated fake-tea placebo drink. To eliminate the ‘comforting’ effect of drinking a cup of tea, the drinks were tea-colored, but masked in the sensory cues typically associated with tea drinking. Then, the groups were subjected to challenging tasks to evaluate their body’s stress response as measured by the hormone cortisol, blood pressure, blood platelet and self-rated levels of stress.

The tasks caused similar stress levels in both groups. However, 50 minutes after the task, cortisol levels had dropped by an average of 47 per cent in the tea drinking group compared with a mere 27 percent in the fake tea group. Researchers also found that blood platelet activation, which is linked to blood clotting and the risk of heart attacks, was lower in the tea drinkers, and that this group reported a more relaxation in the recovery period after the task.

Drink Organic Black Tea for Less Stress

Because tea is chemically complex, researchers can’t yet pinpoint the ingredients responsible for the beneficial effects. What the researchers do know is that enjoying black tea may speed up our recovery from the daily stresses in life, which can help reduce the risk of chronic illnesses such as coronary heart disease.

Stock up on healthy and delicious organic black tea. It’s calorie-free, packed with powerful phytonutrients and can help soothe away stress, too.
