Your Guide to Using Red Light Therapy At Home

Red Light Therapy at Home

Red light therapy is a non-invasive treatment considered natural, safe, and effective based on different reviews and clinical trials. The promising results entice people to try red light therapy even in the comfort of their homes. Red light therapy at home is achievable. There are manufacturers that produce red light devices or lamps in different shapes and sizes. 

How does red light therapy work? Red light therapy works by using light wavelengths that penetrate deep into the skin and affect mitochondria metabolisms to reduce stress and increase circulation. It does not contain any chemical or excess heat. An overall effect of this therapy leads to cell regeneration. 

Can You Do Red Light Therapy at Home?

Red light therapy can be done at home as long as you have the right FDA-approved red device. The first step in doing red light therapy at home is choosing the right device. There are many choices on the market, and it can be a bit overwhelming to find yourself stuck in an aisle of too many selections. 

Once you know the standards and factors to consider, your choices will automatically be narrowed down. It will be easier for you to come up with a purchasing decision that you will not regret over time. 

However, being aware of the considerations literally is not the best way to go. You must have an in-depth understanding of the factors to consider when choosing the right red light therapy device.

Important Things to Consider When Choosing A Red Light Therapy Device

One way of letting yourself experience the best results of red light therapy at home is by choosing the right red light therapy device. Here’s  a list of some important things worth considering:

Size and Coverage

For red light therapy, size always matters. It’s best to invest in a larger device that can cover your body’s wider surface area. It’s also best to choose a larger device to cover for a full treatment than to settle with a smaller one meant for local treatments. Getting the larger device will allow you to treat more cells in your body, giving you the best results. 

Degrees also play a crucial role in the effectiveness of a red light therapy device, so you also need to consider the beam angle. A beam angle is an angle at which the light is emitted from the device. 

Wide-angle beams mean the light can quickly spread to cover a larger surface area, but it tends to lessen intensity with distance quickly. Meanwhile, a narrow beam will cover a smaller area but has more concentrated intensity even when focusing on a certain distance. 

Moreover, a particular manufacturer should specify the intensity at a recommended distance. 

Power and Irradiance

The basics of measuring power include irradiance. Irradiance is defined as the one that measures power units per area. You will typically see it in milliwatts per square centimeter. You can also measure it by considering the rate of energy delivered by the device. 

If you’re hesitant to believe what the manufacturer claims on the red light therapy device’s manual, it’s best to compute it on your own. During red light therapy, you can also compute the irradiance by multiplying it with the treatment time in seconds, then divide it by 1000. 


A red light therapy device’s spectrum ranges from approximately 620 nm to 750 nm. If you want to enjoy a device’s full potential and see relevant results, go for a red light therapy device with a spectrum of 630 nm and 660 nm [1].

You should also refrain from choosing a device with a significant flicker rate that can cause eye strain and headaches.

Numerous clinical trials have proven that red light therapy is a safe and non-invasive procedure. However, the importance of investing in an FDA-approved red light therapy device is a critical factor to consider. Discount brands are selling red light therapy devices that are not FDA-approved. Also, some of these brands do not follow GMP (Good Monitoring Practices) [2]. 

Some red light therapy devices emit non-ionizing radiation through a low-frequency electromagnetic field (EMF). This EMF is often associated with fatigue, loss of concentration, difficulty to sleep, cancer, or electromagnetic hypersensitivity (EHS) as evidenced by a Review entitled Electromagnetic Field-Induced Biological Effects in Humans. It is best to take precautionary measures to limit EMF exposure [3].


Red light therapy devices come in a myriad of designs, ranging from lamps, handheld wands, unique lightboxes, to wearable belts. These designs are among the cheapest devices because of how small they are and the minimal amount of time it will take for you to experience clinically-relevant benefits. 

Moreover, it is best to invest in a design that will work according to your needs. To experience the full potential of red light therapy at home, you must consider getting yourself a medical-grade red light therapy device.

Warranty and Service

Manufacturers put immense faith and value to their products when they know customers can highly benefit from them. Warranty service is the best way to prove that you are getting a legit product. 

Consider choosing a manufacturer that offers credible customer service when abrupt technical difficulties occur. A reliable warranty and service ensure customers that they are getting the right red light therapy device.


Reviews are an excellent indicator to evaluate customer feedback. You can find several reviews on the internet if you search for them. Look for honest reviews to tell you a customer’s feedback in detailed paragraphs based on first-hand experience. 


Prices range from 90 to 120 US dollars. However, prices will still vary depending on the size and the coverage a red light therapy device can handle. Besides, medical-grade red light therapy devices in NYL are always affordable.

Customer Support

The existence of customer support will tell you about the legitimacy of the product. Invest in a red light therapy device with impeccable customer support to give yourself the peace of mind and security you deserve.


Red light therapy devices have been making noise all over different social media platforms and several clinical trials that back them up for their benefits. Thanks to technological advancements, you can already perform red light therapy at home. 

However, red light therapy is not for everyone. Some risks and contraindications come with it. Moreover, it’s best to consult an authorized professional before deciding to invest in a red light therapy device. To enjoy a red light therapy device’s full potential, you must consider some important factors we’ve just discussed.
