Can insomnia cause heart to beat fast?

Answer 1

Yes, an increased heart rate at night could cause insomnia. An increased heart rate tends to induce feelings of the fight or flight response or anxiety. This is something which you should discuss with your doctor in order to rule out any serious health conditions.

Answer 2

If you seem to have a rapid heart rate while you can't sleep at night, it may be anxiety, which is also what's keeping you awake. There are some natural and prescription sleep aides that may help, but if it is anxiety, you also have to address the issues that are troubling you. Be sure to see your doctor.
