Neurologists have warned that drinking black coffee on an empty stomach may increase anxiety, nervousness and mental stress, as caffeine is absorbed more rapidly without food, overstimulating the brain and nervous system.
According to neurologists, caffeine enters the bloodstream much faster when consumed on an empty stomach, causing a sudden stimulation of the brain and nervous system.
This can lead to symptoms such as a rapid heartbeat, trembling hands, restlessness and feelings of anxiety, particularly in people who are already sensitive to caffeine.
Experts said the body's stress hormone, cortisol, naturally reaches higher levels around 30 to 45 minutes after waking up.
Drinking black coffee during this period may further elevate the body's stress response, making feelings of anxiety and nervousness more intense.
Lack of food speeds up caffeine absorption
Medical experts explained that when the stomach is empty, there are no proteins, healthy fats or complex carbohydrates to slow the absorption of caffeine.
As a result, caffeine reaches the brain more quickly and blocks chemicals that promote relaxation, increasing alertness but also raising the likelihood of jitters and anxiety.
Coffee doesn't need to be avoided
Neurologists stressed that there is no need to give up coffee altogether.
Instead, they recommend drinking coffee after breakfast or eating a light snack beforehand, even if a full meal is not possible. Consuming food before coffee can help moderate caffeine absorption and reduce unwanted side effects.
People with anxiety should be more cautious
The experts particularly advised individuals who already suffer from anxiety disorders or chronic stress to avoid drinking black coffee on an empty stomach, as they may be more vulnerable to caffeine-induced symptoms.
Medical professionals also emphasised that the information is intended for general awareness and should not replace professional medical advice. Anyone experiencing persistent anxiety or other health concerns should consult a qualified healthcare provider.
