Boost Your Immune System to Improve Your Heart Health This Season

The colder months with lower temperatures are upon us, which results in a slower immune response and leaves people more susceptible to infection. As our immune system and heart have a direct relationship it is imperative to strengthen your immune system this season.

The Relationship Between Your Immune System and Heart

Did you know that one person dies every 34 seconds in the United States from cardiovascular disease? A few causes of heart disease include smoking, bad diet, lack of exercise, high blood pressure, diabetes, and family history. However, numerous individuals with cardiovascular events do not fall into those categories—inflammation in the body is a significant risk factor.

The most common type of heart disease is coronary artery disease, caused by the build-up of lipids and inflammation that affect blood flow to the heart and interrupt the supply of oxygen, a process referred to as atherosclerosis.

The cholesterol crystals in the plaque build-up in atherosclerosis trigger the release of molecules from the immune system. The molecules cause inflammation and promote blood vessel injury and plaque instability, leading to heart attacks, strokes, and death. Immune cells have receptors that serve as sentry guards, sensing potentially harmful molecules. Moreover, they send out molecules to remove these threats—the strength conditional on your genes.

In summary, the heart and the immune system exchange information and work together through cytokines, hormones, and neurotransmitters.

How to Improve Your Immune System

The heart can modify the function of the immune system, and vice versa; therefore, it is vital to take excellent care of your immune system to sustain heart health. Here are some ways to boost your immune system this holiday season:

  • Stay hydrated

  • Eat nutrient-dense foods

  • Maintain a healthy weight

  • Physical activity

  • Adequate sleep

  • Avoid excessive alcohol

  • Reduce your stress levels
