Whenever you drive at night you think about that Why Can’t You Have Red LED Lights On At Night? Red is a color that conjures up feelings of passion, power, aggression, fury, and even terror. When it comes to your physical and mental health, this is not the case. Bathing in red light at night may help you sleep better and reduce your risk of developing chronic diseases, according to research by Marika Sboros.

Why Can’t You Have Red LED Lights On At Night?

Red light at night generally doesn’t seem to disrupt sleep as blue light does. It might make your sleep better. Even though further research is required, the available data seems to support the notion that red light at night doesn’t interfere with sleep.

Red Light At Night

When you think of red light, what image comes to mind? Is it a traffic light or an Amsterdam neighborhood with prostitutes selling their wares in the windows? Scientists in the United States have a very different perspective. They claim that Red Light At Night is better for your health than blue or white illumination and that the more red light you expose your body to, the better.

A study published in the Journal of Neuroscience by Ohio State University neuroscientists builds on a growing body of research on the health risks of light at night and indicates that the color of the light is the most important factor. Despite the fact that red is a color associated with power, passion, aggression, wrath, and even fear, the study demonstrates that Red Light At Night provides mental and physical benefits.

The researchers studied the impact of various colored lights on adult female Siberian hamsters. Blue light, such as that provided by gadgets and energy-efficient light bulbs, had the most negative effects on the mice’ moods, followed by white light. At night, hamsters exposed to red light fared substantially better.

They reported much fewer depressive symptoms and brain alterations associated with depression. They slept better after that. The only rodents who did the best were those who spent the night in complete darkness.

According to Dr. Randy Nelson, co-author of the study and professor of neuroscience and psychology at The Ohio State University, the findings could have implications for humans, particularly those who work night shifts and are prone to mood problems. While red light is preferable to white or blue light, experts agree that no artificial light at night is the ideal option.

After all, the sun was the primary source of illumination prior to the industrial revolution and the introduction of artificial lighting. People lived in accordance with nature’s rhythms, spending their evenings in relative darkness, lit only by the moon and stars. They took advantage of the sun by getting up early, working outside, and going to bed when the sunset.

Fluorescent lights, television, laptops, mobile phones, and tablets all increased exposure to blue light, which substantially altered behavior patterns. These days, many parts of the world have evening lighting, and we take it for granted that we have easy access to all of those lumens, according to Harvard Medical School researchers who published a recent article in the Harvard Health Letter. According to the experts, we may be paying a price for soaking in all that light.

According to the research, curlicue, compact fluorescent light bulbs, and energy-efficient LED lights create more blue light than normal bulbs. Their negative health impacts usually outweigh any savings from lower energy expenses. Any Light At Night affects the body’s circadian rhythm, and in the worst-case scenario, blue and white light may contribute to cancer, diabetes, cardiovascular disease, and obesity.

Blue wavelengths are useful during the day because they improve concentration, reaction times, and mood, but they can be disruptive at night, according to Harvard researchers. People’s exposure to blue wavelengths has been increasing as a result of the growth of electronics with screens and energy-efficient lighting, especially after sunset, they claim.

The Connection Between Sleep And Light

Melatonin, sleep, and light are all linked. Melatonin is a sleep hormone produced by the brain when it is dark. Melatonin production decreases when exposed to light. According to Dr. Alcibiades Rodriguez, director of the NYU Lang one Health Sleep Medicine Center, melatonin is a sleep marker. Two hours before our customary bedtime, it begins to rise, according to him.

MD, a fellow in the American Academy of Sleep Medicine and associate professor of medicine at the University Of Southern California Keck School Of Medicine, light is the most important factor in training our circadian rhythm to our sleep and waking cycles. This internal clock, known as the circadian rhythm, has a profound impact on sleep quality. The result is that early morning sunshine prevents the release of the sleep hormone melatonin.

Melatonin is released at night after the sun goes down. According to Dr. Rodriguez, light acts as a zeitgeber, a naturally occurring time clue that aids in the regulation of our circadian cycle. Some types of light, on the other hand, may aid in the initiation of sleep, while others may interrupt it.

Sunlight consists of various forms of light with distinct wavelengths measured in nanometers (nm). The visible radiation spectrum for humans comprises colored light with wavelengths ranging from 380 nanometers (purple) to 780 nanometers (red), he says.

Blue light has a short wavelength of 435-445 nanometers, which suppresses the release of melatonin. According to Dr. Dasgupta, this is why Blue Light glasses and shades exist to block blue light and help individuals sleep better at night. When comparing wavelengths, red light has a longer one than blue. Red light, according to Dr. Rodriguez, is less disruptive to sleep than blue light. Ideally, sleeping without lights is preferable, he adds.

Is Red Light Good For You?

Red light treatment may benefit skin health by Increasing the creation of collagen, the protein that gives skin its shape, suppleness, and strength. Boost fibroblast generation, which produces collagen. Skin is made of connective tissue, which contains collagen.

How To Use Red Light For Sleep?

The best option would be to utilize a high-quality red LED light bulb in your room for 15 to 20 minutes regularly before going to bed every day if you want to test out red lights before all the study is in.


This is all about Why Can’t You Have Red LED Lights On At Night? In general, Red Light At Night does not appear to get in the way with sleep as much as blue light does. Actually, it may assist you with sleep improvement. While additional research is needed, the current evidence suggests that red light does not impair sleep at night. Choose goods that emit red light wavelengths rather than bulbs that are just colored red if you want to try Red Light For Better Sleep.

Also, during the day, try to expose yourself to sunlight and brighter lighting, lesser lights in the evening, and darkness when it’s time to sleep. Sleep issues can have a negative impact on your physical and mental well-being. If your sleep problems persist, consult your doctor to determine the best course of action.

Frequently Asked Questions

Why do I see red lights in the middle of the night?

This molecule is known as rhodopsin, or visual purple, is produced by the eyes when they are exposed to very low light levels. Deep red lights do not cause the rhodopsin to be neutralized, which is why astronomers and safety officials employ red lights for night lighting to keep their night vision intact.

Is the red light OK for use in the bedroom?

The color red is non-disruptive. You may rest well knowing that mild red light will allow your body to naturally manufacture melatonin. Red light has the extra benefit of preserving night vision. This makes returning to a dark bedroom after using the restroom in the middle of the night much easier.

What is the significance of the red light on your front porch?

With the usage of red porch lights, the push for heart health awareness has now made its way into homes. Many homeowners may commemorate heart health and awareness by changing the lights on their front porch.

What does it signify when you see a red light?

The ray of light from a crimson angel indicates intelligent service. Angels, who express their love for God by serving on missions assigned to them by God, inspire others to do the same.
