Red Light Therapy for Anxiety, Depression & Mental Health

A record number of people are facing anxiety, depression, and mental health issues. Now is a great time for new ways to tackle these problems. Red light therapy is one such innovative treatment.

While the full impact of red light therapy on mental health is still debated, the evidence is promising. The question is whether LEDs can reach deep into the brain. Can they emit enough red or infrared light to affect deeper brain areas? Fortunately, studies show that light therapy can help with anxiety and depression.

How Red Light Therapy Works for Mental Health

Light is a source of energy. While blue and UV light can harm us, red and infrared light offer many benefits. They can clear skin of pimples, improve eyesight, burn fat, and stimulate hair growth.

Red light therapy, which includes both red and infrared light, is popular among athletes. It helps with muscle growth and rejuvenation. In the last three years, the beauty and anti-aging industries have embraced RLT. Let's explore how it works.

Human body cells are filled with mitochondria. These organelles are key to our cells' energy. They are found in eukaryotic cells.

When exposed to red or infrared light, mitochondria get activated. This light range is between 600 to 1000 nm. It boosts cell growth and repair.

Research shows that energizing mitochondria offers many health benefits. It's a game-changer for our well-being.

Initially, scientists thought it only helped physically. But, they found it might also treat mental health issues. This includes Parkinson’s Disease, PTSD, stress disorders, Alzheimer’s, depression, anxiety, and more.

However, new studies raise concerns. They question if red light therapy can reach the brain. This is where diseases like Parkinson’s and Alzheimer’s start.

Yet, red and infrared light can still help with stress, depression, and anxiety. It shows promise in these areas.

It's crucial to note that infrared lasers should not be used on some body parts. Red laser lights can be harmful, especially to the eyes. LEDs are safer for red light therapy.

Red light therapy is not a substitute for professional mental health care. It should not replace established treatments.

Understanding the Pathophysiology of Mental Health

To understand how red light therapy can help with mental health issues like anxiety and depression, we need to know about brain activity. This activity is key to our mental well-being.

There are several theories on why mental health problems like depression and anxiety happen. We'll look at three simple ones to grasp without getting too deep into science.

1. Neurotransmitter imbalance – This theory says that chemical imbalances in the brain can cause emotional/mental problems. These imbalances happen because of a lack of neurotransmitters like serotonin and dopamine. Also, GABA imbalance can harm brain neurons.

2. Decreased cerebral blood flow – This happens when there's not enough nitric oxide in the brain's frontal lobe. It leads to less oxygen and can damage the brain.

3. Decreased cell energy – This is due to low glucose levels in the brain and problems with mitochondria.

Is Red Light Therapy Good for Mental Health? Data from Studies

Study 1: A 2009 study showed promising results. It involved 10 patients with major depression and anxiety. They received near infrared light therapy, which had positive effects.

This study, along with a bright light study, showed light therapy's benefits. It helped 58 patients by reducing their depression and anxiety.

In all three pathophysiological theories, it's said that depression's causes include brain cell damage.

Red light therapy boosts mitochondria growth and health. This means it can repair and grow new brain cells.

Early studies on PBM (light therapy) for brain issues show promise. It might help with depression, anxiety, and even suicidal thoughts. The data suggests PBM is safe and could be a good treatment for depression. (source)

How Quickly Does RLT Improve Mental Well-Being?

Where is the light shone on the body?

Light is usually directed at the forehead. This is because the prefrontal cortex, behind the forehead, is targeted. It's thought to help with mood and brain function.

The light aims to go through the skull and into the brain. This could change how the brain works and help with healing. But, always get advice from a pro to make sure it's safe and works well.

For how long each day and how many days a week?

For 20-30 mins a day, 3-5 days a week.

How long does it take to see results?

Most see results in 2-4 weeks of use. Many see results even sooner.

At what distance or irradiance?

Helmets sit close to the skin because they block less light. For panels like our TotalSpectrum series, keep 6-12 inches away. This distance lets light penetrate deeper, reaching about 125mW/cm2.

Because everyone's needs are different, it's crucial to talk to a healthcare expert about light therapy. They can help find the best settings for you.

There have been important studies on how light therapy works.

Dr. Theodore Henderson's study [1] showed promising results. A group with mental health issues like depression got 20 red light treatments. They all felt better.

When checked 6 months later, those still using red light therapy at home felt strong. But, those who stopped therapy saw their issues come back in 2 weeks.

This study suggests red light therapy is safe and effective at home. It's a strong reason to keep researching.

What is the Best Light Therapy for Mental Health?

Red light therapy is a safe and affordable way to treat depression. It offers long-lasting results. This makes it a good option for those looking for light therapy.

White light therapy is also effective for seasonal depression. It targets SAD, or seasonal affective disorder. This shows that different light therapies can help in various ways.

Green light therapy is showing promise too. Recent studies suggest blue light therapy can help with mood and anxiety. For more information, check out this guide on light therapy colors.

Which Red Light Wavelengths are best for Mental Health?

Wavelengths are measured by frequency and intensity. At higher levels, any kind and color of light could do damage to the human body. As far as red light therapy, it is best delivered at a wavelength frequency of 600 to 1000 nm with a light intensity of up to 150mW/cm2.

Red Light:

630-660 nm: This range is often used for its ability to promote wound healing, reduce inflammation, and alleviate pain. It has also been investigated for its potential benefits in treating skin conditions and mood disorders.

Near-Infrared Light:

810 nm: This wavelength is being looked at for better brain function. It might help with depression and improve mood.

830 nm: Studies are checking if it's good for brain health. It could help with neurological conditions and boost cognitive performance.

850 nm: Like 830 nm, it's being studied for brain health and thinking skills.

Combination of Wavelengths:

Some studies have used a mix of red and near-infrared wavelengths for better results. If you want a top-notch red light therapy panel with various wavelengths, look at our TotalSpectrum ULTRA.

Red Light Therapy Devices for Better Mental Health

The last piece of the puzzle involves choosing the right devices to deliver red light therapy.

Red light therapy is a new idea, and people are working hard to make the best light sources. Right now, there are some great and affordable panels available.

The 7 Band TotalSpectrum ULTRA has 450nm 610nm 630nm 660nm 810nm 830nm & 850nm wavelengths.

When rating red light therapy devices, we look at how well they work, their features, how long they last, and their cost. Here are five devices that get good reviews:

• Red light therapy beds
• Full body panels
• Specially designed RLT helmets
• Red light therapy head bands

If you struggle with stress, depression, mood swings, or anxiety, visiting your doctor every month for a new prescription can be tough.

Red light therapy might be a better option. It could help with many mental and physical health issues. It's worth considering under the right conditions.
