Caffeine withdrawal is a physical and mental condition that occurs when a person suddenly stops consuming caffeine after having regularly consumed it for a prolonged period of time. Caffeine is a stimulant found in coffee, tea, and energy drinks and is one of the most widely consumed psychoactive substances in the world. 

When a person suddenly stops consuming caffeine, they may experience a range of symptoms including headaches, fatigue, irritability, difficulty in concentrating, dysphoria, and even depression. These symptoms typically peak within the first 24-48 hours of quitting caffeine. As per research, it can last up to nine days. Caffeine withdrawal is not life-threatening but can be unpleasant and uncomfortable.


According to research, the most common symptom of caffeine withdrawal is a headache. This is caused by the sudden drop in blood pressure and the body’s need to adjust to the lack of caffeine. Caffeine consumption causes constriction of blood vessels in the brain, which reduces blood flow.


A 2012 research of 213 frequent caffeine drinkers found that avoiding caffeine for 16 hours enhanced sensations of tiredness. As caffeine is a stimulant, when it’s removed from the body, it can cause extreme fatigue.
