The vagus nerve and the facial nerve are both very important to health and well being.

Nerve Stimulation for Good Health

The Vagus Nerve

The concha of the ear, which is the bowl shaped area just outside of the ear canal, is a very good place to stimulate the vagus nerve. The vagus nerve runs through many areas and organs of your body. Chronic tension and pain in muscles (as well as many other health problems) can be caused by an improperly functioning vagus nerve. Stimulation of the vagus nerve is very important to reduce stress and pain, improve digestion, improve mood and memory, and to help our bodies restore health and well being.

The DopaLights headband has a light on each end. I place the brightest area of one light directly over the concha of my ear, on my right side which is the side where my shoulder hurts. The light on my left side lands just behind my ear, which is also a good place to target the vagus nerve.

The place where the second light lands may vary, depending on the size of your head, but anywhere in front of, or on the concha, or behind the ear, will stimulate the vagus nerve. However, the concha is the preferred target because the nerve is very close to the surface in that area.

You can also use the individual light pieces from the DopaLights wristband to shine light on the concha, or to shine or tape the light on the path of the vagus nerve. I use black kinesiology tape to cover the light from shining out, which helps direct the light inward and holds it on the spot where I want it. When shining light into the concha of the ear, you also increase dopamine. We have light sensitive proteins in our brains which detect light entering through our ears and produce dopamine in response to that light in order to keep us awake and alert during the daytime.

Different colors of light are more or less stimulating to our brains, and can have different effects on our mood. White/blue lights are most stimulating. Green/yellow lights are moderately stimulating. Orange/red lights can still be stimulating, but can also be very relaxing, like looking at a sunset. Our brains know what time of day it is, based on the colors of light in the sunlight spectrum. Although sunlight looks mostly white to us, it is actually made up of all of the different colors, in varying amounts of each color based on the time of day. For example, It is mostly red at sunrise and sunset, and mostly blue at noon. This tells our bodies what time it is and how stimulated or relaxed we should be, based on the time of day.

Stimulating the vagus nerve can be very relaxing, even when using a stimulating light color. This can give you a very pleasant “relaxed and stimulated at the same time” feeling, if you dose yourself correctly. It may take some experimenting to find what colors of light and amounts of time work best for you. Some people respond much more intensely and quickly to the effects than others.

Please be careful not to overdo it or fall asleep while wearing DopaLights. Start with small amounts of time (2-3 minutes) and increase gradually as needed.

The Facial Nerve

Applying the bright, targeted colored lights to the pathways of the facial nerve, not only stimulates and soothes the facial nerve for improved facial firmness and beauty, but it also has been  shown to improve focus and concentration abilities, including the ability to focus on a human voice when there are distracting noises around.

The facial nerve can become inflamed, causing swelling and aching in the face, jaw, cheeks, eye areas, and temples. Light therapy is very soothing and anti-inflammatory for the nerves.

As you can see in the facial drooping on one side of the face in a person with Bell's Palsy, when the facial nerve is not working optimally, it causes sagging and drooping of the face. A healthy facial nerve lifts and firms the face for a more youthful, healthy appearance.

The red, orange, and yellow Dopalights light pieces can be held together or used individually and traced over the jawline, the ear to mouth area, ear to eye area, and ear to forehead area for a few minutes everyday to improve the health and function of your facial nerve.

Light Therapy for Health and Well Being


Our ancestors spent all day everyday out in the sunlight. Our bodies and minds respond to light in amazing ways. Have you ever noticed how a bright sunny day affects your mood and your energy level? Or how gazing at a fireplace or a sunset calms your mind? Did you know that your skin has light-receptors in it also, so that different colors of light can affect your mood and energy even if you can't see them? 

Dreary, cloudy days or artificial indoor lights can be very detrimental to your mood and energy levels. With DopaLights, you can wear the light on your wrist for the same benefits you might get from looking at the lights, which gives you a lot of added control over how the light in your environment affects you.

We have a light color for every mood, available in our DopaLights Soft Vinyl Wristband. 

Red: Relaxed

Orange: Centered

Yellow: Cheerful

Green: Motivated

Blue: Energized

Violet: Inspired

White: Alert

The light pieces slide into a clear plastic pocket on the inside of the wristband and shine light into your wrist. You can change out the pieces with different colors for different moods, or you can use the light pieces individually to shine light on acupoints, wrinkles, spider veins, or areas of pain/injury. 

Each individual light piece is rechargeable and comes with a USB cord. The charge will last for 5-7 hours of use and then must be recharged for 3 hours or more.  

Recommended Supplements

There are some supplements which help to break down acetaldehyde. Alcetaldehyde is a known carcinogenic and may contribute to many chronic illnesses. These supplements also seem  to reduce or eliminate the detoxification type side effects some people report when they "overdo" Dopalights.

What is Light Therapy?


Light therapy is the process of applying light to the body. It can be done with many different wavelengths of light, including red and infrared, and can be done with lasers or LED lights. Low Level Laser Therapy (LLLT) can be used to describe either one, lasers or LEDs. 

Another term which can apply to various types of light therapy is photobiomodulation or PBM.

Light is energy that travels in waves. The distance between waves is called the wavelength. The number of times a wave oscillates per second is called frequency. The longer the wavelength is, the lower the frequency is, and the deeper it penetrates the skin. The human eye is only able to see a small part of the electromagnetic (light) spectrum. The wavelength of the light determines what color we see and what effects the light may have on us. While all of the natural light colors have beneficial effects on us, each color has slightly different effects.

Research - Light Therapy for Inflammation

“One of the most general benefits of PBM that has recently emerged, is its pronounced anti-inflammatory effects... The local reduction of edema, and reductions in markers of oxidative stress and pro-inflammatory cytokines are well established. However there also appears to be a systemic effect whereby light delivered to the body, can positively benefit distant tissues and organs. ”

We have a separate page of our website dedicated to referencing research studies about light therapy and red light therapy, and the benefits which have been found in scientific research studies.

Frequently Asked Questions (FAQ)

Which one should I get? Red Light Therapy or White Light Therapy? Wristband or Headband?

White light therapy is very stimulating. It is good for people who need help waking up or staying awake, such as night shift workers, or to recover from jet lag. Red light therapy is more gentle and soothing, but can also be very stimulating. Red light therapy is a better choice for people who are likely to only tolerate short sessions of a few minutes at a time (such as people with Parkinson's). The wristband is very convenient and comfortable, especially if you plan to wear it for many hours per day. The headband adds the benefits of aural light therapy and stimulation of hair follicles.   

How long should I wear my light therapy headband or light therapy wristband?

Start very slowly, with just 2-5 minutes with any of the light bands, and wait at least a few hours before using it more, to see how you react. People who have chronic illnesses, such as Parkinson's disease, or high toxicity, may experience detox type symptoms (headache, nausea, etc.) if you wear DopaLights too long, which can be even just a few minutes for some people. Gradually add time each use and each day, as tolerated. Some people can tolerate it all day long, and benefit more and more from increased use.  

Should I get the rechargeable wristband or the battery operated wristband?

If you only need 15 minutes per day or less, then a battery operated unit will last you a long time on one battery. The battery in the battery operated wristband will last approximately 30-60 hours and should be changed before it completely runs out because it continues to gradually become dimmer and dimmer until it runs out. The dim light does not produce as strong effects as the bright light. If you are relatively healthy and plan to wear the wristband many hours per day, the rechargeable wristband would probably be best for you.

Which light setting should I choose? Constant on or flashing light?

All of the DopaLights white and red light therapy headbands and wristbands come with 4 optional settings: constant on, slow flashing, and fast flashing. It is only for your preference. Choose any of the settings you like best. Currently, we do not know of any significant differences in effects from any of the settings. Try them all and choose the one you like best. Click on, then keep clicking until you reach the setting you prefer. When you are ready to turn it off, click it through the settings options until it turns off.
