Yes, red light can be harmful, especially when it comes to our eyes. Short-term exposure to red light can cause eyestrain, headaches, and vision impairments. Long-term exposure to high energy visible (HEV) light, also known as blue light, which is close to the visible spectrum of the Sun, has been linked to macular degeneration and vision problems in the future.
Too much exposure to blue light can also contribute to sleep problems, fatigue, and eye strain. Therefore, it is important to be mindful of our red light exposure, especially for long periods of time.
It is also important to note that red light can also affect our mental health. Studies have found that people who were exposed to too much blue light, even at night, were more likely to develop mental health issues, including depression, anxiety, and stress.
This is because blue light can suppress melatonin production, the hormone which helps to regulate our circadian rhythm and regulate our sleep-wake cycle.
In conclusion, red light can be harmful, and those who are exposed to it for a long period of time need to be aware of the risks associated with it and take steps to limit their exposure.
What are the dangers of red light therapy?
Red light therapy is a relatively safe form of treatment, but there are some dangers to consider. As with any form of treatment, there is a risk of side effects, such as skin irritation, redness, or itchiness.
Some people have reported feeling a stinging or burning sensation during or after the session. If you experience any of these symptoms, it is important to speak to a qualified medical professional.
In rare cases, multiple long-term sessions have been reported to have caused an increased risk of skin cancer. While this has not been definitively proven, those at risk or already diagnosed with skin cancer should be aware of the potential risk.
It is generally recommended to avoid any unnecessary exposure to UV radiation, and red light therapy has been found to produce some UV radiation, depending on the device.
Another potential risk is eye damage. It is important to ensure that the eyes are protected from the LEDs during a red-light therapy session. Safety shields should be provided by the administering clinician, and safety glasses should be worn to prevent any direct contact with the light.
Finally, for people who take medications that cause sensitivity to light, like tetracyclines, red light therapy should be approached with caution. Research shows that these medications can create a risk of photosensitivity and the potentially damaging health effects associated with the combination of the two therapies.
Who should not use red light therapy?
Red light therapy is generally safe and poses few risks. However, there (are) a few individuals who should not use red light therapy. Consult with your physician prior to use, if you have any of the following conditions:

What does red light do to your brain?
Red light has been found to have a variety of effects on the brain. Research has found that exposure to red light can improve mood, alertness, and attention, while reducing fatigue and anxiety. Red light stimulates the production of serotonin, which creates a sense of calm, and can help with issues like depression.
It can also increase the production of dopamine, which helps with focus and motivation. Studies have found that red light therapy can also increase overall cognitive performance, particularly in tasks requiring attention – such as math and reading.
Additionally, the calming effect of red light can help stimulate the production of melatonin, which helps with circadian rhythms and promotes a healthy sleep cycle. Overall, red light can have a positive impact on the brain, leading to improved cognitive performance and emotional states.
Is red light therapy FDA approved?
Yes, red light therapy is a clinically-proven and FDA-approved treatment. Red light therapy has been cleared by the FDA since 2003 for a number of conditions, including pain relief, wound healing, and skin rejuvenation.
Red light therapy typically uses near-infrared radiation, usually delivered through devices that emit laser light or intense pulsed light (IPL). The radiation is believed to stimulate the body’s natural healing processes and may help speed up the body’s natural repair processes.
Many studies have shown positive results from red light therapy and its ability to reduce pain, improve tissue recovery, reduce inflammation, and boost the immune system. Red light therapy does not cause any serious side effects, and it is generally safe for the majority of people.
That said, it is always best to check with your doctor before starting any form of therapy.

Why shouldn’t you have red lights on at night?
Red lights should not be used at night because they interfere with the body’s natural circadian rhythm. This is the biological clock that regulates our sleep and wake cycles, and it is triggered by light and darkness.
The shorter wavelength of red light tricks the body into thinking it is still daytime, which can disrupt this natural cycle and create difficulty sleeping or feeling energized during the day. Additionally, research has shown that red light can suppress the release of melatonin, which is the hormone responsible for regulating sleep.
Lastly, red light can also make it difficult to see in darker conditions, causing safety hazards and preventing people from distinguishing objects in the environment.
Is red light good for mental health?
The answer to whether red light is good for mental health is not a one-size-fits-all answer. Red light is used in many different contexts and may be beneficial or harmful to mental health depending on the situation.
For example, some studies have shown that exposure to red light can be beneficial for some people suffering from non-seasonal depression. Specifically, research suggests that red and near-infrared light therapy improve symptoms of depression in many individuals.
This is likely due to the fact that red light is known to increase serotonin production and provide an anti-inflammatory effect, which can help improve mood and overall well-being.
On the other hand, excessive exposure to red light can be detrimental to a person’s mental health. Prolonged exposure to red light can lead to an overexposure of high-energy visible light, which can be damaging to one’s eyes and cause mood changes.
Furthermore, recent research suggests that exposure to the blue light usually emitted from modern screens can lead to feelings of depression and anxiety.
Overall, the benefits or harms of red light exposure depends on the context and the individual’s personal situation. In some cases, red light may be beneficial for mental health, but in other cases, it may be detrimental.
It is important to consult with a mental health professional to determine whether red light exposure is right for you.
Does red light therapy do anything?
Yes, red light therapy does have some beneficial effects on the body. It is mostly used to reduce inflammation, improve circulation, and stimulate the production of collagen, the main component of skin and connective tissues.
Red light therapy uses low-level light wavelengths to penetrate the skin and target specific areas, such as inflammation or pain. It has been used to treat a variety of medical conditions, including chronic pain, mental health problems, and even skin conditions.
For instance, it has been used to improve the appearance of wrinkles, age spots, and acne, as well as help reduce redness, swelling, and discoloration. Additionally, studies have shown that red light therapy can also be beneficial for mood and sleep, as it increases serotonin, which is a neurotransmitter responsible for regulating mood, emotion, and sleep patterns.
Finally, red light therapy has been found to activate the cells that produce energy in the mitochondria, which helps enhance overall physical performance and fatigue. Overall, red light therapy appears to be effective for a variety of ailments and its beneficial effects are being explored more extensively.
Is red LED light cancerous?
No, red LED light is not cancerous. Light-emitting diode (LED) lights are not known to cause any long-term health effects including cancer. LED lights emit light of a single color and therefore do not contain the ultraviolet radiation (UV) which is linked to sunburns, skin cancer and eye health issues.
This is why LED lights are commonly used in tanning beds, to avoid the harmful UV radiation. LED lights are also much more efficient and environmentally friendly than other traditional lighting sources.
LED lights use very little electricity and last up to ten times longer, reducing environmental pollution and waste. Additionally, LED lights have no mercury in them, unlike other light sources such as compact fluorescent lamp (CFL) bulbs, which contain small amounts of mercury.
Can LED red light cause cancer?
No, LED red light does not cause cancer. Although LED lights can emit light in the same frequency (or color) as ultraviolet light, LED lights do not emit any ultraviolet light and therefore are not a health hazard.
LED light does not contain any kind of ionizing radiation and is known to be safe to use in any context. Additionally, LED lights typically have very low heat output, which helps cut down on radiation intensity and any associated health risks.
Certain scientific studies have suggested that too much exposure to blue light (which LED lights can also emit) can have a negative effect on our circadian rhythm, and there are some theories that this could lead to increased risk of cancer, but no definitive evidence has been found to support this theory and LED lights do not produce enough blue light to cause any serious health concerns.
Is it healthy to sleep with red LED lights on?
No, it is not healthy to sleep with red LED lights on. The artificial blue light from LED lights can reduce the level of melatonin in the body and make it harder to get a good night’s sleep. Although some research has suggested that red LED lights may help promote circadian rhythms and reduce sleep disturbances, other studies have found the opposite to be true.
Red LED lights may, in fact, reduce melatonin production and disturb sleep patterns, especially when used in the evening. Additionally, red LED lights may trick the body into thinking it’s still daytime and make it harder to fall asleep.
It’s best to avoid using any type of LED lights in the bedroom, ideally in the evening and throughout the night.
Why do LED lights have cancer warning?
LED lights have cancer warnings due to their ability to produce blue light radiation. Blue light radiation has been studied and has been found to cause potential damage to the cells in the retina, which could be linked to age-related macular degeneration and other long-term vision problems (known as phototoxicity).
It is also known to affect an individual’s quality of sleep and can cause occasional headaches for certain people. LED lights produce a much higher proportion of blue light radiation than traditional lights, and as such, many LED products come with cancer warnings to ensure consumer safety.
It is recommended that people who are exposed to LED lights utilize specialized eyewear to protect their eyes and limit the amount of blue light radiation they are exposed to.
Can you get skin cancer from LED grow lights?
No, you cannot get skin cancer from LED grow lights. Skin cancer is typically caused by overexposure to UV light, which is a type of light outside of the visible spectrum. LED grow lights, on the other hand, emit light exclusively within the visible spectrum, meaning they do not produce UV rays that can cause skin cancer.
However, some LED grow lights may require a cooling fan or heat sink to remain operational, and these mechanisms may produce heat that can cause irritation and burns if exposed directly to skin for extended periods of time.
As such, it is important to maintain a safe distance from LED grow lights whenever possible to prevent burns from occurring.
