Coffee on your stress level
Does this mean that the anxiety-triggering effects of coffee depend on your tolerance to caffeine or how much you regularly drink in a day? A study conducted on 25 healthy male individuals found that those who drank about 300 mg of caffeine actually had double the amount of stress as those who drank the placebo.
Also, it has been found that the stress levels were actually similar between regular coffee drinkers and less frequent coffee drinkers. This suggests that caffeine has the same effect when it comes to stress levels whether you are a frequent coffee drinker or not.
How to drink coffee for alertness
You also have to consider the fact that the caffeine content in a cup of coffee varies. But generally, a grande coffee cup from Starbucks would have around 330 mg of caffeine. If you are drinking coffee to become more alert, take a low-to-moderate dose.
Larger coffee doses can trigger edginess and anxiety. It helps to observe how you respond to the amount of coffee you are drinking to determine how much you can tolerate. To be safe, if you feel that you are jittery or nervous, it is a good idea to reduce your caffeine intake.
