Healthy Val: The Science of Love and Your Heart

They say love makes the heart race, but does it also make it healthier?

It’s been twenty days into the "month of love," and I’ve been thinking about what to share on Scripted Care. This time, I didn’t eavesdrop on my senior colleagues’ conversations, nor did I discover an extra nipple beyond the ones I’ve already shared about (please read previous posts). So, I needed a new punchline to guide my thesis, and here it is:

As a young adult, building relationships and breaking the ones that need to be broken,I can testify that love, whether Agape, Platonic, Erotic, or any other type, affects the body in ways we often don’t realize.

A priest once said that the reason miracles happen consistently to people with faith is that they open their hearts to the love of Christ. That unwavering love births trust, which in turn enhances miracles. While Christ performs the miracle, their body's receptiveness plays a role. I believe this because I have witnessed it.

But here comes the big question: How does love affect the body biologically?

Let’s explore this together.

 

Did you know that love is powered by four key hormones?

• Oxytocin (the "love hormone")

• Dopamine (the "pleasure hormone")

• Serotonin (the "mood stabilizer")

• Cortisol (the "stress hormone")

Oxytocin is a biochemical regulator that plays a major role in reproduction, bonding, and behavior. It is produced in the brain and released into the bloodstream by the pituitary gland. This hormone not only strengthens relationships but also protects the heart and repairs injuries such as heart attacks and heartbreak.

Dopamine is a neurotransmitter responsible for feelings of pleasure, motivation, and satisfaction. It plays a key role in attraction and romantic excitement.

Serotonin is an endocrine signal, found in the gut, that regulates digestion, mood, and sleep. Have you ever been so drawn to someone that you couldn’t sleep? That’s the result of increased serotonin and oxytocin production!

However, hatred and jealousy disrupt the heart’s rhythm. Chronic anger introduces stress-related heart diseases over time, narrowing blood vessels and increasing the risk of cardiovascular issues.

 

The Dark Side; When Love Hurts the Body

Love isn’t always sweet. When relationships break, the body reacts.

Cortisol is released by the adrenal glands in response to stress, including heartbreak. When heartbreak occurs, it triggers the body’s "fight-or-flight" response. A significant increase in cortisol can lead to:

• High blood pressure (HBP)

• Increased heart rate

• Difficulty concentrating

• Weight gain

• Digestion problems

Broken Heart Syndrome

Heartbreak physically affects the heart. It can weaken the heart muscle, mimicking a heart attack or, in some cases, causing an actual one. The heart’s structure changes temporarily under extreme emotional distress.

Symptoms include:

• Sweating

• Irregular heartbeat

• Shortness of breath

• Chest pain

• Dizziness

 

Love and the Body Beyond the Heart

We’ve sailed this far, but before I let you off the hook, here are some important health facts:

• Happiness and affection strengthen immunity, hate and stress weaken it.

 

• Love improves digestion, while heartbreak and stress contribute to ulcers and indigestion.

• Love reduces pain and promotes relaxation.

If Christ were to heal you right now, the state of your heart would matter. A heart filled with love and peace enhances healing, whether spiritual or physical. This is why bitter and resentful people often struggle with healing. Not only because bitterness is a negative state for the soul, but also because it physically restricts blood flow and weakens the heart.
