We all have certain pillow preferences. You might prefer a single, flat pillow; your partner might need to surround himself with 10 separate pillows of all different sizes in order to nod off. (Psst—here’s how to pick the perfect pillow for the best night’s sleep!)
But your pillow choices could be a sign of more than just your personal preferences. Cardiologist Dennis A. Goodman, MD, explains that people with congestive heart failure commonly feel more comfortable when they sleep with multiple pillows.
Here’s why: People with heart failure tend to experience shortness of breath while they lie flat; this discomfort goes away when they sit up. Difficulty breathing can obviously hinder your ability to sleep, so stacking multiple pillows relieves the discomfort and helps with sleep. If you’ve noticed yourself or a family member recently experiencing shortness of breath while lying down or needing more pillows than usual in order to sleep well at night, this could be a red flag for heart failure symptoms.
It might seem strange to feel short of breath while lying down (as opposed to jogging or taking the stairs), but it has to do with the fluids in your body. When you lie down, fluid recirculates from the legs and puts increased pressure on the lungs and cardiovascular system, which means a weakened heart (one with heart failure) has to work harder to pump.
If you are experiencing shortness of breath while lying down and have not yet discussed this with a doctor, schedule an appointment soon to get tested for heart failure and—if necessary—get treatment for your heart failure symptoms.
