Everyone knows that coffee and black tea can be pretty great at helping you feel energized in the morning. That’s because caffeine is a jolt to your system, speeding up your heart rate and increasing the rest of your body’s normal functions. Coffee and black tea also improve attention and increase problem-solving skills that you’ll need at your job or just around the home taking care of chores. Even one cup a day is enough to get that brain excited for challenges. Scientists have noted that drinking coffee helps prevent age-related memory loss, including the dreaded Alzheimer’s disease.

However, if you struggle with anxiety, you will want to limit the amount of caffeine you drink. It excites your nerves and can heighten the tension that you already experience. And if you already have depression, the caffeine crash can worsen your symptoms. Stick with one cup of coffee in the morning and then a cup of green tea to perk you up in the afternoon. Green tea is powerful in the fight against both anxiety and depression and can even help with other mental health problems, including bipolar disorder and schizophrenia. With less caffeine, you will have fewer jitters and a less-overwhelming crash, and the high levels of antioxidants just may override those unpleasant side effects altogether.
