Feeling your heartbeat in your head is often due to the sensation of blood pulsing through the scalp arteries, which expand with each heartbeat. This becomes noticeable when the heart is pumping harder than usual or blood vessels dilate. Common causes include physical activity, changes in body position (such as lying flat or bending forward), stress, caffeine intake, sinus congestion narrowing venous outflow, or high blood pressure, which makes arterial pulsations more forceful. This sensation can also be linked to pulsatile tinnitus, where blood flow changes near the ears or head transmit the beat of the pulse, sometimes heard as a rhythmic thumping or whooshing sound. While usually benign, it can sometimes signal issues like atherosclerosis, blood vessel disorders, or high blood pressure that warrant medical evaluation. If you regularly feel your heartbeat in your head, especially if accompanied by other symptoms like headache, dizziness, or if it is persistent and bothersome, it is wise to consult a healthcare provider to rule out serious causes and get appropriate management.
