Many people have had the unusual sense of hearing their heartbeat while resting in bed. For some, this rhythmic sound piques their interest, while others are concerned about potential health risks. Here’s all you need to know about this phenomena, including when it’s natural and when you should seek medical assistance. Why do you hear your own heartbeat on your pillow?
Hearing your heartbeat while lying on your side is usually natural. According to Dr. Anthony Youn, a US surgeon, this sound is frequently generated by the carotid artery pressing against your pillow. The carotid artery is a significant blood channel that supplies blood to the head and neck. When you lie down, the proximity to your ear can magnify the sound of your pulse, much like a bass drum.
The peaceful setting of nighttime can make internal sounds like your heartbeat more audible. This impact is most noticeable when external noises are minimal, allowing you to detect your body’s natural rhythm. The Importance of Pulsatile Tinnitus. If the heartbeat sound persists or becomes unpleasant, you may have pulsatile tinnitus. Pulsatile tinnitus differs from typical tinnitus in that it fits the rhythm of your heartbeat rather than a constant ringing or buzzing.
According to Tinnitus UK, this illness is frequently caused by changes in blood flow near the ear or an increased awareness of that flow. Dr. Youn notes that while pulsatile tinnitus is normally harmless, it is crucial to seek medical attention if the sound is persistent or disturbing, as it can occasionally suggest underlying health problems. Common Causes of Pulsatile Tinnitus. Pulsatile tinnitus can be caused by numerous sources, including:
High blood pressure raises the force of blood flow, making it turbulent and noisy. Atherosclerosis: Hardened arteries near the ear can induce turbulent blood flow, which magnifies interior sounds. Anemia and hyperthyroidism increase blood flow, which can cause pulsatile tinnitus. Ear Abnormalities: A ruptured eardrum or thin bone structures in the ear might amplify blood flow noises. In some situations, head or neck tumors may cause pulsatile tinnitus by pressing on surrounding blood vessels.
