Are LED Lights Harming Your Health?

 • LED lighting is everywhere. It's used at home, school, work, and on the street. It conserves energy and lasts longer than traditional bulbs. However, there is rising concern about the effects on health. Alexander Wunsch, a German doctor who studies light and its effects on the human body, explains why LED lighting may not be as harmless as it appears. His research focuses on how various forms of light affect cells, the eyes, and overall health.

What changed with modern lighting?

• Previously, people used candles and incandescent bulbs. These light sources produced both visible light and infrared radiation. Infrared light is beneficial to your body. When LED lights replaced older bulbs, you lost this portion of the light spectrum. LEDs primarily emit visible light, particularly blue light, and lack crucial wavelengths such as near infrared. This alteration altered how artificial light interacts with your body.

Infrared light:

• Infrared and near infrared light are crucial for your health. These wavelengths can penetrate your body's tissue up to one inch deep. They travel through garments and into your cells. This type of light promotes healing and repair. It promotes your body's recovery from daily stress. It also increases blood flow and promotes energy production within cells.

Hidden problem of LED flicker:

• LED lights flicker quickly. You cannot see this flicker with your eyes, but your body can detect it. This continual flicker can harm your brain and nervous system. It may cause stress, headaches, and exhaustion. According to certain research, it can also have an impact on hormonal balance. Over time, this imperceptible flicker may cause deeper disturbances in your body.

How infrared light support energy production?

• Your cells require energy to function. This energy is produced inside microscopic structures known as mitochondria. Infrared light helps these mitochondria function more efficiently. It stimulates the creation of energy in the form of ATP. This procedure keeps your body fit and healthy. Without enough infrared radiation, your cells may not work optimally. This can have long-term consequences for your health.

Impact of LED blue light on eye:

• LED lights create a large amount of blue light. This form of light has a short wavelength and a high energy content. Long-term exposure to blue light can harm your eyes. It raises the risk of macular degeneration. This disorder affects the center of your vision and is a leading cause of blindness in older persons. Continuous exposure to LED screens and illumination might accelerate this damage.

Effect on sleep:

• Your body has a normal sleep cycle. Melatonin is the hormone that regulates this cycle. Blue light from LEDs inhibits the release of melatonin. When melatonin levels decline, your sleep is disrupted. You may find it difficult to fall asleep. Your sleep quality may also deteriorate. Poor sleep has a negative impact on your emotions, focus, and overall health.

Comparison with natural sun light:

• Natural sunshine has a whole spectrum of light. It comprises visible light, infrared, and ultraviolet radiation. This equilibrium promotes your health. Sunlight helps regulate your sleep cycle, boosts your mood, and promotes vitamin D production. LED illumination does not provide the entire spectrum. It lacks the near-infrared component, which is necessary for repair and recovery.

Avoiding LED is not practical:

• LED lighting has become ubiquitous in everyday life. It is utilized in homes, offices, on mobile devices, and in public places. You rely on it for daily tasks. So the idea isn't to fully remove LEDs. The idea is to use them carefully while minimizing their negative effects.

Choosing better LED bulb:

• Not every LED bulb is the same. Some are intended to lessen health concerns. When purchasing LED lights, seek for specific qualities. Choose lamps with low flicker rates. This alleviates stress on your brain and eyes. Check the CRI (Color Rendering Index). A high CRI indicates that the light is closer to natural sunshine. Look for values greater than 90.

Importance of R9 value:

• R9 is a component of the CRI measurement. It demonstrates how well a light source reproduces red colors. Natural light has a strong red tone. Many inexpensive LED bulbs lack this feature. When you select bulbs with R9 values greater than 90, you receive a more balanced light. This improves visual comfort and lowers strain on your eyes.

Simple change you can make:

• You can take simple precautions to protect your health. Use soft lighting in your bedroom. Avoid using screens before going to sleep. Select high-quality LED bulbs. Spend time outside during the day. These simple steps help mitigate the detrimental impacts of LED lights.

Is your lighting helping your health or silently harming it?
