When you remove the caffeine it has the opposite affect though, and you can start to feel overtired and drowsy. Adenosine is the chemical compound that makes us feel drowsy (2), hence why a cup of coffee helps us feel more awake. We are looking for that boost and feeling of alertness we get from our morning coffee.Ĭonsuming caffeine reduces fatigue and increases your alertness by blocking receptors to a adenosine. Most of us enjoy our coffees in the morning, and this is not by coincidence. The severity and length of the headaches will depend on how big the change in rate is and also on how quickly your brain can adjust to the new flow. It is the sudden change in blood flow rate, that is responsible for the painful headaches associated with caffeine withdrawal. When you stop drinking coffee or reduce your caffeine intake, this allows your blood vessels to open up again and you have an increase of blood flow to the brain. The reduced flow causes the blood vessels to constrict. Just 2 cups of coffee contain enough caffeine to reduce cerebral blood flow by more than an quarter (27%) (1). We are not just referring to average headache though, no, withdrawal headaches are more severe like those associated with migraines. Of all the reported caffeine withdrawal symptoms, the headache is the most common.
