Caffeine in Tea... Friend or Foe? Balancing Caffeine Benefits and Blues

Did you know your cup of tea may be providing you with some caffeine benefits? If you've been concerned about caffeine in your tea, keep reading to learn about potential benefits of the naturally occurring caffeine in your delicious, healthful cup of tea.

If you enjoy one or more of the wonderful teas from the Camellia sinensis tea plant (including black, oolong, pu-erh, green, and white teas), it's a good idea to stay informed about the potential benefits and side effects associated with caffeine, since each of these teas does contain some caffeine. (Learn more about the amount of caffeine in tea here.)

Many of us tend to have a love/hate relationship with caffeine. Although we worry about caffeine's possible side effects (like insomnia, anxiety, and headaches), we still relish the physical and mental benefits caffeine can provide!

While caffeine's potential negative side effects do receive a lot of attention in the media, remember that caffeine (in moderation) can be good for us in many ways, as well! Here are some of the benefits caffeine may provide.

Caffeine Benefits at Work

Boost energy and stamina with caffeine

If you're feeling fatigued or need a boost to get through the next few hours to finish a project or your afternoon at work, a cup (or pot!) of tea may help!

Studies have shown that consuming a moderate amount of caffeine can lessen physical and mental fatigue, increase energy, and leave you feeling less tired after a busy day. Learn more about this research here.

Improve cognitive performance with caffeine

Not only can caffeine provide a much-needed lift when your energy is low, but it may improve your cognitive functioning in many ways, as well. 

Caffeine can increase alertness, enhance short-term memory, improve accuracy, boost problem-solving and decision-making skills, and help you focus better and longer on tasks that require your full attention (like exams or an important presentation at work), too.

How long do caffeine benefits last?

The effects of caffeine can last for up to six hours or more, so you may enjoy these physical and mental caffeine benefits for some time after you've finished that last drop of tea!

And, since research suggests that consuming moderate amounts of caffeine on a regular basis can provide consistently improved cognitive functioning, why not consider adding a cup or two of healthy, beneficial tea to your daily routine to enjoy these caffeine benefits?

Support good brain health with caffeine

Including some naturally caffeinated tea in your diet may benefit your overall mental health, too.

A recent study (you'll find it here) suggests that caffeine boosts long-term memory, and other research has indicated that regular, moderate caffeine consumption (especially in coffee, and in tea, as well, to a lesser extent) may provide protection against age-related cognitive decline, dementia, and Alzheimer's disease. (Learn more about this research here.)

Caffeine Benefits

And, more good news - research targeting the effects of caffeine on Parkinson's disease has found that caffeine intake may help to prevent the onset and progression of this common neurodegenerative disorder (you'll find more information about this research here).

Herbal teas (which are also called 'tisanes'), such as Rooibos, cinnamon, chamomile, and peppermint, are naturally caffeine free. An exception is yerba mate, which is an herbal tea that does contain caffeine.
