Blue light is part of the visible spectrum, and it plays a critical role in adapting our body to light and dark cycles, helping us establish our circadian rhythm. You might already know about the effects of blue light on the brain, and that’s why many reading glasses filter out blue light.

Blue light keeps us awake at night, simulating sunlight. It tricks the brain into believing it’s still daytime, and that’s why you struggle to get to sleep after checking your phone and playing around on Instagram before you settle down for the night.

However, blue light therapy in a regulated and controlled setting can be beneficial to your health. The use of a blue light laser provides your body with several advantages.


What Is Blue Light?

A blue light laser is a variety of electromagnetic radiation wavelengths within the known electromagnetic spectrum. You get both invisible and visible light, with UV and infrared light sources accounting for the invisible ranges, while the rest are visible.

Colors occur due to the different wavelengths of light moving in the spectrum. Out of all the colors in the visible spectrum, blue light has a wavelength of 446 – 477-nm, promoting the strongest reaction in our circadian rhythms and physiology.

The pigments in your skin and eyes react to this blue light wavelength, allowing for treatments to enhance your skin and vision.


What are the Health Benefits of Blue Light Therapy?


Eliminate Bacterial Vaginosis

BV is a bacterial infection caused by several factors. Douching or cleaning the vagina after sex can strip it of its beneficial bacteria, creating an imbalance of the microorganisms living in your vagina. We all have beneficial bacterial in our tummy and our vagina, and when they get out of balance, it starts to cause issues.

Blue light therapy can help to resolve BV faster than leaving it alone. Your doctor will likely prescribe your antibiotics and probiotics to help you bring the situation under control. Adding blue light therapy to your treatment program can accelerate your recovery.


Control Depression

During the winter in the Northern Hemisphere, the skies turn grey, and so does the demeanor of the population. It’s common for people to experience a drop in mood around the beginning of the winter. It’s such a common occurrence that it even has a medical term – SAD (Seasonal Affective Depression).

While SAD will lift when the weather improves, it can ruin your sense of well-being if it gets out of hand. Blue light therapy can assist with elevating serotonin levels in the brain, lifting the affected individual out of their seasonal depression.


Resolve Skin Problems

People living with skin disorders like psoriasis, eczema, keratosis, and acne may have issues affecting the health of their immune system, and its effects on the skin. The increase in immune system T-cells increases the presence of localized inflammation, promoting the formation of keratinocytes.

Blue light therapy has an anti-inflammatory effect on the IL-1alpha cytokine production, with the high-intensity light radiation killing off the excess T-cells causing the issue.


Stop Fatigue

If you’re dealing with chronic fatigue during the day, blue light therapy might help you recover your normal energy levels. By using blue light, you can alter the circadian rhythms, keeping your brain in rhythm with its wake and sleep cycles.
