Why do i wake up with a fast heart rate if i don't drink?

sometimes i wake up during the night and my heart is racing as if i%26#039;m having a panic attack. it takes ages for it to return to normal regardless of how much i try to calm down. i don%26#039;t remember having had a nightmare or an especially %26#039;active%26#039; dream prior to waking, although it%26#039;s possible i did and just don%26#039;t remember.

a similar thing used to happen to me when i drank alcohol, but i%26#039;ve since stopped drinking so it can%26#039;t be alchohol-related. i eat a stable, healthy diet and exercise daily. does anyone know why this is happening?? i have a normal heart beat during the day...

hopefully it is nothing serious. However, if you answer yes to any of the following when your heart is racing, then you should see a doc:

chest pain, shortness of breath, lightheadedness.

Your idea of having nightmares is my best guess. And a lot of the time people do not remember their dreams. When in REM sleep, your mind is organizing memories and producing dreams; any thought [that your brain creates during sleep] can trigger your heart beat to race.

If you don%26#039;t drink? Do you mean not drinking enough water:

Your heart may have to work extra hard to pump blood to your body and brain if you are lacking fluids in your diet (Remember that a lot of your blood is made up of water). Also, for different people [maybe for you!] a lack of water or even something you ate or drank right before bed, can cause a reaction in the body where your veins will

Shrink and become narrow: blood travels much faster.

or

Widen: it is harder for the heart to pump blood when the blood vessels are wider.

Create a journal and record what you have eaten, drank, and any physical/mental activites you participate in 8-10 hours before bed. This may help you come up with your own answer to you problem!
