Red light therapy (RLT) is widely used for boosting skin health, reducing inflammation, and supporting cellular energy. But what happens if you’re feeling under the weather — should you continue using it when you’re sick?
How Red Light Therapy Works
RLT uses low-level red and near-infrared light to penetrate the skin and stimulate mitochondria — the energy centers of your cells. This increases ATP (cellular energy), reduces inflammation, and promotes healing.
Potential Benefits While Sick
When used during mild illnesses like colds or fatigue, red light therapy may offer:
- Immune system support by improving circulation and reducing inflammation
- Faster recovery by enhancing cellular repair
- Energy boost when you’re feeling tired or weak
- Relief from sinus congestion when used around the nose and face
Many users report feeling more energized and less congested after sessions during colds or flu-like symptoms.
When to Avoid
- If you have a fever, serious infection, or sensitive skin due to illness, it’s best to pause therapy.
- Always consult a healthcare provider if you’re dealing with a chronic condition, taking medications, or unsure if RLT is appropriate during your illness.
Conclusion
For most people with mild cold symptoms, red light therapy may help support healing and ease discomfort. However, if you’re experiencing a more serious illness or fever, take a break and focus on rest first.
