Treatment And Prevention

Treatment for heart palpitations depends on the cause. For most people, palpitations will go away on their own without any treatment. For others, treating the underlying cause of the palpitations can help stop or prevent them. The following tips may give relief from heart palpitations:

Stop being anxious

If anxiety or stress leads to heart palpitations, look for ways to reduce your worry. This may include activities such as meditation, gentle exercise, yoga, or tai chi. If these techniques aren’t enough, work with your doctor to find a medication that can ease symptoms of anxiety.

Remove tricky food and substances

Drugs, medications, and even foods can lead to palpitations. If you identify a substance that’s causing palpitations, eliminate it from your consumption. For example, cigarette smoking can lead to palpitations. Stop smoking for a period of time and see if the heart palpitations end.

Embrace healthy living

It’s crucial to take care of your body by staying hydrated, eating healthy, and getting regular exercise. These components of a healthy lifestyle will reduce your risk for heart palpitations.

Look for a cause-related treatment

Let’s assume your heart palpitations are due to an illness or disease, your doctor will work with you to find a suitable treatment. This treatment option may include medications and procedures.

Take a shot at relaxation techniques

Stress can trigger or worsen heart palpitations. This is because stress and restlessness can make your adrenaline spike. But managing your stress through relaxation can help. The good options include meditation, tai chi, prayer, and yoga.

Try a cold shower

You can take a cold shower or simply splash cold water on your face. Or apply a cold towel or icepack to your face for 30 seconds. Consequently, the jolt of the cold water will stimulate the vagus nerve which connects your brain to your heart.

Drink water

Also, dehydration can cause heart palpitations.  For the reason that your blood contains water. This means that when you become dehydrated, your blood becomes thicker. Therefore, the thicker your blood is, the harder your heart works to move it through your veins. This can increase your pulse rate and possibly lead to palpitations.

Hence, if you feel your pulse going a notch higher, reach for a glass of water. If you notice your urine is dark yellow, drink more fluids to prevent palpitations.

Restore electrolyte balance

Equally, some electrolytes that can benefit your heart health include potassium, calcium, magnesium, and sodium. These are better obtained through foods like avocados, bananas, sweet potatoes, and spinach. And eat more dark leafy greens, dairy products, nuts, and fish. Likewise, supplements may help restore electrolyte balance. Still, it’s wise to discuss with your doctor first.

Bottom Line

Finally, why does my heart palpitate at night? The reasons why I get heart palpitations are now clearer. Firstly, I am afraid and anxious about the future. Secondly, I am stressing over the effect of the COVID-19 lockdown on my family and business. Then again as soon as I identified the reasons – fear, anxiety, and stress, the solutions became obvious. Subsequently, I tried to calm down with a more positive attitude to life. I know what I can control. And accept what I can’t. From then on, I noticed that the palpitations at night stopped.

In addition, it’s worth remembering that, while heart palpitations at night can be concerning, it’s likely nothing to be worried about. Since the palpitations will likely go away on their own without any lasting issues.

However, if these sensations continue and you’re worried they may be a sign of an underlying health issue, see your doctor. As tests can help your doctor eliminate any possible serious issues, find a diagnosis and a treatment.
