Does Red Light Therapy Help Your Immune System?
Can Red Light Therapy Make Your Immune System Stronger?
Yes, it can help. Red light therapy gives your cells more energy, which helps your immune system work better. This means your body can fight off germs, like viruses and bacteria, more quickly.
It can also lower long-term inflammation in your body. Too much inflammation makes it harder for your immune system to do its job. When your inflammation is balanced, your body can respond faster when you get sick.
Many people who use red light therapy say they don’t get sick as often and recover faster from colds or small infections. It’s not a replacement for eating healthy, washing your hands, and getting rest, but it can give your immune system extra support.
Can It Help Prevent Colds and Flu?
By helping your immune system work better, red light therapy may lower your chances of getting sick. It helps your body make more immune cells and get rid of viruses faster. Some studies show people recover quicker from colds when they use red light therapy.
This works because red light boosts blood flow, lowers inflammation, and helps repair cells. Using it during cold and flu season may help you stay healthier, recover faster, and have milder symptoms.
Can It Increase White Blood Cells?
Yes, it may. White blood cells are your body’s “security guards.” They fight off germs and repair damage. Some studies show red light therapy can increase how active and how many white blood cells you have.
It may also improve blood flow to areas where immune cells are stored and activated. While more research is needed, the early results suggest it can help your immune system stay alert and ready.
Which Conditions Benefit the Most from Red Light Therapy?
- Allergies: Less congestion and itching.
- Respiratory Infections: May help you recover faster (but still see a doctor).
- Skin Irritation: Can help reduce redness and calm the skin.
What Science Says
Scientists look at how red and near-infrared light affect the immune system. Your cells use this light energy to make changes that can either calm an overactive immune system or boost a sluggish one.
What to Expect from Using Red Light Therapy
You might notice calmer skin, less irritation, and faster recovery after being sick. Some people see milder allergy symptoms during allergy season. Results depend on how often you do it, the type of device, and your health starting point.
How to Plan Your Sessions
- Session Time: Start with 10-15 minutes per area.
- Frequency: 2-3 times a week for 4-6 weeks, then switch to weekly sessions if you see progress.
- Before & After: Clean your skin, remove makeup, and drink water.
- Seasonal Adjustments: Use it more often during allergy season or times when you get sick easily.
Safety Tips
Red light therapy is gentle and noninvasive. Most people find it relaxing. Check with your doctor first if you:

Avoid using it over open wounds unless your doctor says it’s okay and always protect your eyes.
