Many observers fasting during Ramadan may experience headaches, often described as a throbbing or dull ache, signaling caffeine withdrawal.

While some attribute these headaches to hunger or low blood sugar, scientists point to caffeine withdrawal as the primary cause.

This condition, known as "withdrawal headache," is a physiological response to the sudden absence of caffeine.

Caffeine narrows blood vessels in the brain; abrupt cessation causes these vessels to expand, increasing blood flow and pressure on nerves, leading to headaches, irritability, poor concentration, and fatigue.

Research suggests that adenosine accumulation in the brain after caffeine withdrawal contributes to drowsiness and headaches.

The simultaneous abstinence from coffee and tea during the long fasting hours of Ramadan intensifies withdrawal symptoms, especially for those consuming over 200 mg of caffeine daily (two to four cups of coffee).

Studies indicate that headaches typically begin within 24 hours of caffeine cessation and can last for several days as the body adjusts.

Nutritionists advise waiting one to two hours after Iftar (the evening meal breaking the fast) to drink coffee, preventing strain on the stomach and nervous system, particularly with rapid blood sugar increases after eating.

Experts caution against breaking the fast with coffee, emphasizing the importance of starting with water and dates to restore fluid balance and energy before consuming stimulants.

To mitigate caffeine-related headaches during Ramadan, experts recommend gradually reducing caffeine intake before Ramadan, drinking water first after Iftar to replenish fluids, and waiting one to two hours before drinking coffee to avoid dizziness and stomach upset.

They also advise against excessive consumption to prevent headache and tension recurrence.

In many Arab households, coffee is integral to Iftar, a habit blending social custom and biological dependence on caffeine, making sudden withdrawal challenging.
