Brain Waves and the Effects of Red and Near-Infrared Light

Our bodies are full of natural frequencies that influence what we feel, do, and think—and vice versa. Brain waves, which we’ll mention frequently, are electrical impulses flowing through the brain, measured in cycles per second, or Hertz (Hz).

There are six primary types of brain waves, each linked to different states of consciousness:

Gamma waves: Associated with memory and information processing. (>30 Hz)
Alpha waves: Linked to calmness, relaxation, and healing. (8–12 Hz)
Beta waves: Related to alertness and wakefulness. (12–30 Hz)
Delta waves: Connected to deep sleep and the unconscious mind. (0.5–3.5 Hz)
Theta waves: Involved in dreaming and deep meditation. (4–8 Hz)
Infra-low waves: Associated with basic brain timing and function. (<0.5 Hz)

These waves help us regenerate while we sleep and keep us alert and energized when awake. Depending on which waves dominate, they influence how our body and mind function. Higher-speed waves typically correspond to alertness, while slower ones are associated with relaxation or sleep.

A 2021 study showed that low-level laser therapy (LLLT) operating at 10 Hz with an 850nm wavelength significantly boosted brain activity. The results demonstrated a notable positive impact on alpha and theta waves, with higher dosages potentially affecting beta and gamma waves and lower dosages primarily impacting alpha and theta waves.

The Science Behind Pulsing

The pulsing feature in red-light therapy devices offers targeted benefits, such as improved memory, enhanced focus, and better cognitive function overall. If you’re familiar with Photobiomodulation (also called low-level laser therapy), you know that red and near-infrared light penetrate the skin to energize cells, almost like charging a battery.

At a pulse rate of 10 Hz, combined with near-infrared light, this effect can penetrate deeper into the body. This boosts nitric oxide production, improving blood circulation and cerebral blood flow. Better circulation means more oxygen and nutrients for the brain, promoting alertness, reducing brain fog, and enhancing overall cognitive performance.

This targeted effect is especially beneficial for specific treatments rather than full-body applications.

The concept of pulsing initially gained traction in medical research, particularly in studies on Alzheimer’s disease. Alzheimer’s brains are characterized by β-amyloid plaques, which are detrimental to cognitive function. Pulsing red and NIR light at specific rates has shown promising results in reducing plaque density. While we’re not medical professionals or producing medical devices, we believe it’s vital to share knowledge about the science and technology behind pulsing and its broad applications.

What is Brain Fog?

Brain fog isn’t a medical condition but rather a term used to describe mental sluggishness. Everyone experiences brain fog occasionally, especially during periods of stress, poor sleep, or aging. However, persistent brain fog can negatively affect both mental and physical well-being.

Common signs include:

Difficulty focusing on thoughts or conversations.
Trouble remembering information.
Challenges multitasking or switching between tasks.
Zoning out during conversations.
Struggling to pay attention to surroundings.

Brain fog can stem from various causes, including medical conditions like ADHD, long COVID, insomnia, or nutritional deficiencies. It’s important to discuss persistent brain fog with a healthcare professional to determine the underlying cause.

While it’s not synonymous with fatigue, brain fog can coexist with other symptoms. Addressing lifestyle factors like nutrition, sleep, and exercise is often the first step in managing it.

What Helps Combat Brain Fog?

Experts recommend evaluating lifestyle factors, including diet, physical activity, and sleep quality. Some nutrients that support brain health include:

Vitamin D
Vitamin C
B-Complex vitamins
Magnesium
Omega-3 fatty acids
Zinc

Here are additional tips for maintaining a healthy brain:

Learn new skills or pursue educational activities.
Engage in regular physical activity.
Eat a nutrient-rich diet with whole foods.
Limit caffeine intake to avoid its rebound effects.
Participate in social activities.
Prioritize good-quality sleep.
Reduce screen time, especially before bed.
Focus on one task at a time instead of multitasking.

Lastly, incorporating Photobiomodulation, particularly pulsing red light, can provide significant benefits for brain health.

How to Use the Luminous Labs Essential “Brain Boost” Setting

Our brain-boost setting is specifically designed to support cognitive health. Use it in the morning and switch to continuous light an hour before bed. Pairing the pulsing function with near-infrared light allows for deeper penetration and more pronounced benefits.

Pulsing vs. Flicker

Pulsing should not be confused with flicker, which can have negative effects on eye health and potentially cause headaches.

Pulsing: A controlled on-off pattern of light designed to enhance therapeutic effects.
Flicker: Unintentional changes in brightness, often from household lighting, which can stress the brain and eyes.

Flicker is something we aim to avoid in red-light devices.

Conclusion

Our bodies rely on specific frequencies to regulate emotions, behavior, and regenerative processes. Applying pulsing near-infrared light has shown benefits like:

Clearing brain fog.
Enhancing focus and concentration.
Improving cognitive functions.
Supporting cellular regeneration.

Pulsing is distinct from flicker, which can have negative effects. The Luminous Labs Essential now features a pulsing setting at the scientifically proven optimal frequency of 10 Hz. Curious? You can check it out here.
