Can heart palpitations be caused by a lack of sleep?

Absolutely. Sleep deprivation is a known risk factor for many heart problems, including palpitations. Not only does lack of sleep cause your heart to work harder due to the body's stress response, it can also disrupt hormones that help regulate blood pressure and electrolyte levels in the body, affecting your cardiac rhythm. In addition to physical effects, emotional stress from being sleep deprived has been associated with increased instances of arrhythmias (irregular heart beat).

So if you're having trouble sleeping or are feeling particularly stressed out, it is important to address these issues before they become more serious problems for your heart health. Make sure you're following good sleep hygiene habits and managing any stress triggers in order to keep your heart healthy!
