According to behavioral cardiologist Michael Miller, MD, listening to music, attending a comedy show, and enjoying a bowl of fresh blueberries are a few ways you can improve your mood and, in turn, prevent or heal cardiovascular disease.

During his July wellness talk, Dr. Miller, explained how chronic stress causes cellular aging, which can damage blood vessels and lead to clogged arteries. The good news: We can avoid and reverse the effects of this life-threatening process by cultivating positive emotions.

Here are some of Dr. Miller’s mood-lifting tips for optimal heart health:

Play music

Listening to your favorite tunes can lift your spirit and decrease stress. Dr. Miller has found that stress causes the blood vessels to close up and harden, preventing proper blood flow. Over time, this can lead to major issues in your cardiovascular system and cause heart disease.

The next time you find yourself in a stressful situation Dr. Miller recommends grabbing your mp3 player or popping in a CD. Listening to music or playing an instrument can have a refreshing and joyful effect on the body, which will help keep those blood vessels open. Try not to become attached to the same song; eventually you will become immune to those enjoyable jingles.

Laugh a little

Dr. Miller believes laughter is not only good for the soul but also excellent for the heart. As with music, he’s found that daily laughter can decrease stress, which helps to regulate blood pressure and open up blood vessels.

Try unwinding with funny video when coming home after a long day, or replace a dinner date with an evening of stand-up comedy. Having a good belly laugh consistently can help release built-up tension and defend your heart against threats.

Get a cinnamon boost

If you’re feeling fatigued or suffering from a clouded memory, grab a jar of cinnamon. According to Dr. Miller, smelling cinnamon can improve your memory and alertness. That’s not all this spice can do; eating cinnamon can optimize your heart health by regulating blood glucose, lowering blood pressure, and reducing triglycerides, whiich can contribute to heart disease if levels are too high.

To give yourself a daily mood and energy lift, Dr. Miller recommends using a cinnamon or peppermint fragrance as a freshener in your car to reduce fatigue. At home, try adding cinnamon bark oil to a steam inhaler, which has been found to induce euphoria, or swirl one-half teaspoon of cinnamon into your morning cup of coffee to help jump-start your day.

Enjoy Nice Cream

To conclude the July event, Lisa Miller, DPM—a holistic podiatrist in the Johns Hopkins health system—demonstrated how to make her Blueberry Nice Cream, a delicious raw, vegan, gluten-free, and dairy-free ice cream alternative with heart-healthy ingredients. The recipe is featured in Dr. Michael Miller’s acclaimed book Heal Your Heart, and you can find variations online.

Developing safety, persistence, trust

Healing is facilitated through safety, persistence, and trust.

  • Persistence: “People did not simply progress through this sequence and experience healing. The healing journey was a recursive, back and forth process. They found helpers, used the skills/resources that those helpers provided, found other helpers that provided more resources and used those skills and resources. As this process continued, people experienced a gradual amelioration of their suffering. Although many despaired at times, all demonstrated the quality of persistence—they refused to give up.”
  • Safety & Trust: “To connect to helpers, it was essential for people to feel safe in those relationships and able to trust that the person would be a helper and not a barrier to healing. Persons whose wounds included a violation of trust were especially careful about testing the safety of new relationships.”

Acquiring Resources

Resources support us as we heal. They include reframing, responsibility, and positivity. “Making connections enabled participants to acquire and refine resources and skills that were essential in their healing journey. People also brought their own personal strengths to the journey.”

  • Reframing: “A particularly important skill was the ability to reframe—that is to look at suffering through a different lens.” This does NOT mean minimizing trauma or pain, but rather it often means the opposite: understanding what happened was wrong, unfair, or uncontrollable and that we are not to blame for it.
    • “I think I kept trying to convince him I was crazy. And he kept saying, ‘No, you’re not crazy.’ […] You wouldn’t necessarily say a Vietnam Vet was crazy. You’d say they are responding like you’d expect to extraordinary circumstances.”
    • “I’m not the only one who have [sic] this problem. A lots, millions of people, you know. […] They don’t have nothing to do with that. I guess I have to live.”
  • Responsibility: While we don’t have control over what happened to us, we are the only ones who can help ourselves heal. “A third essential resource that people acquired or refined was the ability to take an appropriate amount of responsibility for their healing journeys. They participated actively in the process of healing. Once again, some participants already had developed this skill, and some acquired or refined it from their helpers.”
    “You need a lot of energy and a lot of work … it takes a lot of work. It doesn’t just happen. It’s not like a magic wand.” This patient understood that they had to actively participate in the healing process.
  • Positivity: “Another resource that people acquired or refined during their healing journey was choose to be positive—that is to have some optimism about their situation.” People have varying predispositions to positivity. In the study, positivity was important in helping people heal. This doesn’t mean a toxic positivity, but rather simply finding some good in life and feeling hopeful about our situations.

Helping Relationships

“Connection to others was an essential part of all the healing journeys.” Humans are social creatures, and even the most introverted of us need close relationships. Friends and family add meaning and value to life and help support us, in good times and bad. When we experience relational trauma, relationships can feel scary, but reestablishing safety and trust in relationships is where the healing happens. (To be clear, we do not mean reestablishing safety and trust with abusers, but rather finding other healing relationships.) “When safety and trust had been established, people were able to connect with helpers. The nature of the behaviours of helpers that fostered healing ranged from small acts of kindness to unconditional love.”

  • “Moving from being wounded, through suffering to healing, is possible. It is facilitated by developing safe, trusting relationships and by positive reframing that moves through the weight of responsibility to the ability to respond.”
  • “Relationships with health professionals were among these but were not necessarily any more important to the healing journey than other kinds of helpers, which included family members, friends, spirituality and their God, pets, support groups, administrators, case workers and supervisors.”


Healing probably means different things to different people, but one definition that emerged from the study is: “The re-establishment of a sense of integrity and wholeness.” Healing was an emergent property that resulted from each individuals’ complex healing journey, a result of bridged connections between resources and relationships. Healing, in this sense, does not mean cured—none of the study participants were cured of their ailments—”but all developed a sense of integrity and wholeness despite ongoing pain or other symptoms.” In varying degrees, “they were able to transcend their suffering and in some sense to flourish.” When we begin to heal, we find increased capacity for hope, renewed motivation to help others, and are more able to accept ourselves as we are.


Suffering is the ongoing pain from wounding. There is debate about whether or not one actually needs to experience suffering on the path to healing.


Wounding happens when we experience physical or emotional harm. It can stem from chronic illness or by physical or psychological trauma for which we do not have the tools to cope, or a combination of those factors. “The degree and quality of suffering experienced by each individual is framed by contextual factors that include personal characteristics, timing of their initial or ongoing wounding in the developmental life cycle and prior and current relationships.”
