Caffeine makes you feel alert because it blocks adenosine - a neurotransmitter that activates drowsiness and exhaustion. That is why caffeine often feels like a quick fix. However, caffeine can cause serotonin depletion in the long run. When serotonin is low, there is a risk of mental health problems such as anxiety and depression.
