5. Hormones
Have you thought about your hormones? It could very well be your hormones that are the cause of your heart palpitations, especially if you’ve already read through most of this list as it is and been unable to find the cause for your suddenly accelerating heart rate. There are many reasons that your hormones could be out of balance, and just some of these reasons can include your diet, going through phases in your life like menopause or puberty and external factors – it’s been proved that consuming certain types of food will up and lower your hormone levels accordingly.
This can do a lot of different things to your body, only one of which is increasing the pressure on your heart – and a surge in heart rate that you will likely experience as heart palpitations when they happen. You should visit your doctor if this is the case with you.
