4. Anxiety
Can you believe that an excess intake of caffeine can lead to anxiety and stress? Despite the fact that a cup of coffee is supposed to give you energy and adrenaline to focus and be able to function, higher doses can do more damage than good. Most people have been known to experience anxiety, mood swings, and similar symptoms at exceptionally high daily doses of 1,000 mg or more, although caffeine-sensitive people may have the same symptoms with even a moderate intake.
Furthermore, it has been demonstrated that taking little amounts all at once might speed up breathing and raise stress levels. Please remember that each individual is different, which is why you need to follow your own everyday reaction to coffee to learn how much your body can handle.
