FAQ | Find your answers to common questions the CERA System

In the context of red light therapy, the term "wavelength" refers to the distance between two peaks in the electromagnetic wave of red or near-infrared (NIR) light used for therapy. Red and NIR light used in therapy have different wavelengths, and the specific wavelength range used can affect the therapeutic outcomes.

Red light therapy typically uses wavelengths in the range of 620 to 750 nanometers, while near-infrared light used in therapy typically ranges from 750 to 1200 nanometers

The CERA Headband is a red light therapy device that uses multiple wavelengths for therapeutic purposes.

The wavelengths used in the CERA Headband are:
630 nanometers (nm)
850 nm
940 nm
1070 nm

These wavelengths have been chosen for their specific therapeutic effects.
In order for light to penetrate the skull and reach the brain, longer wavelengths of light are needed. This is because longer wavelengths, such as those in the near-infrared (NIR) range (e.g., 850 to 1070 nm), are able to penetrate deeper into tissue than shorter wavelengths (e.g., 630 to 660 nm).

The skull is relatively thick and dense compared to other tissues in the body, and shorter wavelengths of light are absorbed more readily by the tissue and scattered, limiting their ability to penetrate deeper. Longer wavelengths, on the other hand, are less absorbed and scattered by the tissue, allowing them to penetrate deeper and reach the cortex of the brain.

This is why red light therapy devices that are specifically designed for brain stimulation use longer wavelengths in the NIR range.

A brain wave, also known as neural oscillation, refers to the electrical activity that is produced by the brain when it is functioning. Brain waves are generated by the synchronized activity of large groups of neurons as they communicate with each other through electrical impulses.

Brain waves, or neural oscillations, are thought to exist because they facilitate communication between different regions of the brain. The brain is a complex network of neurons that are constantly communicating with each other to perform various cognitive, sensory, and motor functions. Brain waves are generated by the synchronized activity of large groups of neurons as they communicate with each other through electrical impulses.

These electrical signals produce different patterns of brain waves that are associated with different states of consciousness, mental activity, and sensory processing. For example, slow delta waves are associated with deep sleep, while fast gamma waves are associated with attention and conscious perception.

Brain waves are also thought to be involved in various cognitive processes, including memory consolidation, attention, and sensory processing. For example, studies have shown that alpha waves are associated with attentional focus and memory consolidation, while theta waves are associated with creative thinking and problem-solving.

There is growing scientific evidence to support the use of modulated light to influence brain waves. It may work by entraining the brain to a specific frequency. This is based on the concept of neural entrainment, which suggests that the brain has a natural tendency to synchronize its activity to external rhythmic stimuli.

In the case of modulated light, the rhythmic changes in the light frequency may influence the brain's electrical activity and cause it to synchronize with the frequency of the light. This can result in changes in the amplitude and frequency of brain waves, which can affect cognitive states such as relaxation, focus, and alertness.

The CERA Headband employs pulsed frequencies at 7.8 Hz, 10 Hz, 40 Hz, and 100 Hz.

The pulsed frequencies in the CERA Headband are configured in its six preset programs, each with a distinct function based on its name. Users have the option to manually select the program, but it is recommended to seek guidance from a brain coach. Additionally, there is an option to choose a program with a constant wave that does not have pulsing frequencies.

The CERA System emits red light that penetrates the skull to reach the brain, as well as irradiating the gut, where it activates photoreceptors and triggers a series of biological responses that promote the production of energy and neurotransmitters, leading to improved brain function and enhanced gut-brain communication.

The CERA System has 6 pre-set programs that will allow you to select the most appropriate protocol for your own wellness goals. To get the most from the system we do recommend taking up the CERA brain coaching sessions, or seeking the advice of a qualified expert.

The CERA System can be used with the pre-set programs to give a general increase in wellness and body harmony over time. In order to use the system in the most effective way, a brain coach will take your case history and possibly some measurements of brain function and health status - and will use these metrics to give you a bespoke program to meet your specific goals. You will be assessed and supported on a regular basis to see if the intervention is having the desired effect, and to make changes to the protocol as you progress on your wellness and performance journey. If you use a tracking device such as an Oura ring, Whoop, Garmin or similar - the data can be used to assess your progress.

We are all different, and we all respond to therapeutic interventions at different rates. The time it takes to see real differences in wellness and performance depends on your starting point and the effort and dedication you put into your own wellness program, as well as other lifestyle factors.  In some studies, participants reported improved mood and cognitive function after a few sessions of red light therapy. However, in other cases, it may take several weeks or even months of consistent treatment to see significant improvements. It is important to note that red light therapy is not a one-size-fits-all solution and the results may vary from person to person.

Red light therapy for the brain is generally considered safe, but some people may experience temporary side effects, such as headaches, dizziness, or skin irritation. It is important to follow the recommended guidelines and protocols to minimize the risk of any potential side effects.

You can overdo it. Light therapy has what is known as a bi-phasic dose response. That means that too little light will have little effect, and too much light may cancel out any benefits. There is a sweet spot. We recommend using the CERA System once a day or 3-5 days a week, or have the instruction of a CERA brain wellness coach.

The devices use infrared light, so there will be some warmth generated. The devices are not uncomfortably hot.

We are very aware of the deleterious effects of non-native EMF’s and have taken steps to ensure that the CERA System has extremely low EMF emissions. The battery is shielded and there is a Bluetooth kill switch feature on the headband to prevent Bluetooth communication whilst the device is on the head.

Our bodies have a circadian clock that is entrained with the phases of the sunrise and sunset. As the CERA System contains red and near infrared light as is predominantly seen at these times of day – it is possible that using the devices within these times will be most beneficial. However, the system can be used any time that works with your schedule.

Yes, if supervised by an adult and under the guidance of a healthcare professional.

No, the headband fits over the forehead and so the light will not shine in the eyes. We recommend not to look at the lights while they are turned on.

The light should shine directly on to the skin. You can wear clothes but make sure the CERA headband and CERA body panel are used on bare, clean and dry skin. 

Yes, there is a warranty of at least 12 months. Please refer to the manual for the warranty in your specific region.

Yes, there have been scientific studies on red light therapy. In fact there are 1000’s of peer reviewed scientific papers on the topic. You can find these studies by searching online academic databases such as PubMed (www.ncbi.nlm.nih.gov/pubmed), Scopus (www.scopus.com), and the Cochrane Library (www.cochranelibrary.com). In these databases, you can search for studies using keywords related to red light therapy, such as "photobiomodulation," "near-infrared light therapy," or "low-level laser therapy." You can also search for specific conditions or areas of the body that you are interested in to find studies that are relevant to your needs. Additionally, many studies can also be found by searching the websites of professional organizations in the field, such as the World Association for Laser Therapy (www.walt.nu) and the International Association of Photobiomodulation (www.photobiomodulation.org).

The CERA System is FDA listed. That is not the same as FDA approved. At the moment, there is no classification for red light therapy as a therapeutic for a brain health condition. We are hoping to do our part in supporting research to change this. We will soon have a 510K classification for pain reduction, wound healing and increased micro-circulation.

This means that we cannot make claims to cure, prevent, treat or diagnose any brain illness.

No, SAD lamps contain a full spectrum (all colors or wavelengths) of light to mimic the Sun, stimulating a hormonal response. The CERA system uses only red and near infrared light to deliver energy to the body – although the CERA System may help boost mood.

Yes, you can use the CERA Headband without using the CERA Body Panel to target the brain only. We recommend using the devices together for maximum therapeutic effect.

Yes, you can use the CERA Body Panel on joints, limbs and anywhere else you would usually use a red light device. You do not need the CERA App for this.

Yes! Near infrared light can penetrate bone and reach the outer layer of the brain. The longer the wavelength of light, the deeper the penetration. The CERA Headband contains 3 different wavelengths of near infrared from 850-1070 nm in order to reach the maximal amount of light receptors in the brain.

There are light clusters on the forehead and one that goes one the back of the head under the hairline. The CERA Headband does not cover the whole head. The reason for this is that hair is a barrier for light. The best way to get light to the brain is via the prefrontal cortex on the front part of the brain. The brain is a connected network of neurons and support cells. There is evidence that the therapeutic effect of shining light to the forehead area is brain wide via these connected networks, and by stimulating the blood around the head and body.

BrainTap and CeraThrive differ significantly in their approach to brain wellness. CeraThrive uses red and near-infrared light therapy (photobiomodulation) to stimulate long-term healing by promoting cellular repair, improving blood circulation, reducing inflammation, and enhancing ATP production, which supports deeper healing processes. It targets the gut-brain axis for comprehensive wellness.

CeraThrive and BrainTap could potentially complement each other if used together. CeraThrive’s red and near-infrared light therapy focuses on long-term healing by stimulating cellular repair, reducing inflammation, and supporting the gut-brain axis, promoting overall brain health and vitality. Meanwhile, BrainTap offers more immediate mental benefits through brainwave entrainment, using audio and pulsed light to promote relaxation, focus, and mental clarity. By combining CeraThrive’s healing properties with BrainTap’s cognitive enhancements, users might experience both long-term brain health benefits and short-term mental performance improvements.

However, consulting with a healthcare professional before using both technologies together would be ideal.BrainTap, on the other hand, utilizes pulsed light combined with audio technology to stimulate the visual cortex and induce brainwave states like relaxation or focus. While BrainTap provides short-term mental enhancements, it is not primarily a healing tool but rather a brainwave entrainment device. CeraThrive is grounded in clinical evidence, using red and near-infrared light therapy for long-term healing by promoting cellular repair, reducing inflammation, and improving blood circulation, targeting the gut-brain axis for deep, sustained healing. In contrast, BrainTap is not a healing tool but uses pulsed light and sound technology to stimulate the visual cortex and create temporary brainwave states
