Ask the experts
When I lie down at night with my head on my pillow I can hear my heart beating loudly in my ears. It is often so loud that I cannot get to sleep. I have borderline high blood pressure, could that be it?
It is very common to sense your heart beat while lying in bed - rarely is it anything serious, but certainly this sensation will be aggravated if your blood pressure is high. If your blood pressure is normal, it most likely is not a cause of concern. It may also be intensified by any heightened "catecholamine" release (for example, adrenaline) state, such as caffeine consumption, anxiety, fear, etc.
