Every day, your body fights off countless threats thanks to the powerful defense your immune system provides. But did you know that the same habits you use to strengthen your immunity also protect your heart? It’s true, and the connection runs deeper than you might think. Chronic inflammation, often triggered by poor lifestyle habits, is a key driver of both weakened immunity and cardiovascular disease.
Enhancing your immune system not only fortifies your defenses against illnesses but also plays a pivotal role in maintaining heart health.
While the latest research shows that most people miss more than a week of work every year due to illness (CDC), heart disease remains the leading cause of death in the U.S., claiming more lives than all forms of cancer and accidental deaths combined (American Heart Association).
The good news is that by making small, intentional choices each day, you can build resilience from the inside out — helping your heart beat stronger and your immune system stay ready for whatever comes your way.
Ready to set yourself up for success? Here are four simple ways to build resilience from the inside out.
Strengthen immunity & heart health with these 4 daily habits
- Exercise Regularly to Boost Immunity and Heart Health
Do you spend more time in one spot or more time in movement? Do you look for the closest parking spot or park farther away to get more steps? In physical therapy, exercise is what we preach to our patients every day as science has proven time and time again that “movement is good medicine.”
The cells of your body help to keep you alive. They need nutrients and they produce waste products that must be exported. Movement facilitates this process. As you move your body and avoid sitting for long periods of time, your muscles help pump your blood just like an extra heart. As your muscles squeeze, the lymph fluid which sits and builds up in your tissues also gets pumped out of your body. When this process works better, your body has more energy to work on its own defense systems.
Also, when you exercise regularly your body goes into “autophagy.” This means your body kills off the sick and diseased cells that you are carrying around which drag you down and make you sick. Autophagy is your body’s natural way of keeping the good cells strong and getting rid of the excess baggage of sick and dying cells.

Research suggests that 20–40 minutes of movement per day can enhance circulation, reduce inflammation, and promote overall resilience (BJU Health Insights).

- Fuel Your Body with Heart-Healthy, Immune-Boosting Foods
Are you a “convenience eater” or an “emotional eater”? Do you often eat fast-food or “cook” meals that come in a freezer box? Do you include natural foods in their natural states throughout the day? Are you consuming enough fresh fruits and vegetables? What does your diet look like?
Science has shown that foods with added sugars can significantly increase blood sugar levels, triggering the release of insulin and inflammatory proteins throughout the body. This inflammation doesn’t just harm your immune system — it also contributes to the development of heart disease by promoting arterial plaque buildup. High-sodium foods, while damaging to immune function, can also increase blood pressure, a leading risk factor for heart disease. Salt can suppress the body’s natural anti-inflammatory responses and disrupt the balance of gut bacteria, further contributing to systemic inflammation. Fried foods, similarly, can weaken the immune system by promoting inflammation, causing cellular dysfunction, and damaging gut health. As our gut bacteria becomes compromised, it leads to what scientists refer to as “leaky gut.” This condition, where gaps form in the intestinal walls, allows harmful pathogens to enter the bloodstream, triggering immune system dysfunction and increasing the risk of chronic diseases, including heart disease.
A diet rich in immune-boosting, heart-healthy foods, like fatty fish, nuts, and fiber-packed legumes, can help lower inflammation and support optimal function. Omega-3s, found in foods such as salmon and walnuts, are particularly beneficial for reducing the risk of heart disease while strengthening immune defenses (EatingWell).
👉 Try this: Add a serving of fatty fish to your meals twice a week and snack on a handful of nuts daily.
- Prioritize Quality Sleep for a Strong Immune System and Healthy Heart
When was the last time you woke up without an alarm and it was in time for you to go to work or get the kids up and off to school? When you wake up do you feel rested? Do you have a regular bedtime and make sure you follow the same sleep and wake patterns daily?
According to the Center for Disease Control, 1 in 3 Americans don’t get enough sleep. How much is enough? While different people require different amounts of shut-eye based on a variety of factors, the CDC advises consistently getting 7–8 hours per night.
During sleep, your body releases proteins and antibodies which help fight off infections. When your sleep is compromised, this cell production is also compromised, and it is easier for infections to take hold. Additionally, long-term lack of sleep will increase your risk of obesity, diabetes, and cardiovascular disease, which in turn will increase your susceptibility to opportunistic diseases such as pneumonia and Covid-19.

Do you want to know one more thing that you can do to help you sleep better each night? Exercise is the answer! Studies show that those who exercise regularly, fall asleep faster and do a better job going into deep sleep and REM sleep, which in turn helps your body heal and stay more resilient while also supporting your heart health. So work movement into your daily routine to enhance your bedtime routine.
👉 Try this: Create a relaxing bedtime routine — like reading or a warm bath — to signal to your body that it’s time to wind down.
Sleep VS Exercise: Which Is More Important?
Many people struggle with the question of whether to prioritize sleep or exercise. The quick and easy answer (when you are really in a bind), is prioritize sleep. However, both sleep and exercise are very important to our overall wellness.
- Manage Stress to Strengthen Your Immune System and Heart
Do you find yourself feeling anxious and stressed out each day? Do you have healthy “coping mechanisms” to deal with the stress of life, or do you find yourself making unhealthy choices in the heat of the moment?
Mind management is where the 3 strategies above all come together! When we manage our minds appropriately, we sleep better, we make healthier food choices, and we select more healthy coping mechanisms including exercise to deal with stress. AND, as we incorporate the 3 strategies covered above, we better manage our minds. It’s a two-way street!
The American Psychological Association highlights how stress management is essential for both mental and physical health (APA). Incorporating stress-reducing techniques like deep breathing, meditation, or yoga can lower cortisol levels and support overall well-being.
When we experience stress and we are unable to cope appropriately, our body shifts into “fight or flight” nervous system response (the sympathetic nervous system). In chronic “fight/flight” our body releases excessive amounts of cortisol and adrenaline which over time weakens immune system and increases the risk of heart disease. Additionally, did you know that they way you breathe may keep you in a more painful state each day, can result in feeling increased anxiety and can slow your body’s healing processes?

One strategy for shifting out of the sympathetic nervous system and into the parasympathetic (rest and repair) is proper breathing. We must SLOW our breathing to shift our nervous system state. Try this simple strategy at home while sitting comfortably: Breathe in for a 4 count, hold for 2 counts, and then exhale for 6 counts. Practice this for a couple of minutes and you will be surprised how your body moves into a better state of “calm.”
👉 Try this: Set aside 10 minutes each morning for mindfulness meditation to start your day with a calm, focused mindset.
How physical therapy supports your heart and immune health
Your heart and immune system are deeply interconnected, and the habits you cultivate daily can significantly impact both. Whether it’s exercising regularly, fueling your body with the right foods, managing stress, or getting quality sleep, these simple yet powerful practices can help fortify your immune defenses and support your cardiovascular health. However, sticking to these healthy habits can sometimes feel overwhelming, and that’s where physical therapy can play a key role.
