Red Light Therapy & Heart Health 🌅❤️
This American Heart Month, we’re spotlighting photobiomodulation (red + near-infrared light) — a modality that supports cardiovascular health at the cellular and vascular level.
🔬 What the science suggests:
• Mitochondrial & cellular energy support:
Red and near-infrared light stimulate mitochondrial activity, increasing ATP production — essential for heart muscle cells, which have high energy demands.

• Nitric oxide & blood flow:
Photobiomodulation may increase nitric oxide availability, promoting vasodilation and improved endothelial function — both important for healthy circulation and blood pressure regulation.

• Inflammation & oxidative stress modulation:
Research shows red light can reduce oxidative stress markers and inflammatory signaling, which are closely linked to cardiovascular disease progression.

• Emerging cardiovascular applications:
Preclinical and early clinical studies explore PBM for myocardial protection, recovery after ischemic injury, and cardiovascular aging pathways.

✨ Why this matters:
Red light therapy offers low-stress, non-invasive support for cellular function, circulation, and vascular health — making it a powerful complement to a heart-healthy lifestyle when used consistently.
⚠️ Red light therapy is not a replacement for medical care but may support overall cardiovascular wellness alongside movement, nutrition, and stress management.
