The Top 4 Health Hazards of Artificial Lighting

Artificial lighting is very important for humans. Just like everything else in life, it has its own benefits and short comings. For so long we have always depended on artificial lighting to enhance our vision among other things. In normal circumstances we fully take advantage of natural lighting during the day, but when night falls we find ourselves in need of man-made lighting. Some features of artificial lighting may be dangerous for your health.the top 4 health hazards of artificial lighting

Here they are:


  1. Eye damage

Long exposures to some kinds of artificial light can be dangerous for your eyes. The eye is very sensitive and should be protected from harm at all costs. Artificial light is known to cause photochemical reactions in the eyes which damage the retina. Glaring too much at blue or flickering light causes the retina to strain and stress what leads to pterygium. This is an eye condition whereby the tissue growth around the cornea becomes abnormal triggering at the same time macular degeneration and harming the retina.

That’s why it’s so important to pay attention to such characteristics as color temperature and ripple level when choosing light bulbs. For more safety it’s better to choose lamps of neutral or warm tints and with flickering under 5-6%.


  1. Skin health disorders

Despite the fact that your skin needs tanning sometimes, it is prudent to avoid over exposure to ultra violet rays associated with tanning beds. It’s a reality that you can never substitute the role of natural sunlight in regard to your skin health. Vitamin D and Calcium are essential for your bones strengthening and skin overall health. Many consumers use electric tanning beds to tan their bodies. As a result, they unknowingly increase their chances of developing chronic actinic dermatitis causing inflammation that can lead to acute skin cancer among other diseases.

Some artificial light sources such as CFLs emit UV rays. Most their part is transformed into visible light due to special substances inside the bulb. But to avoid the risks it’s better to use LEDs or incandescent bulbs.


  1. Disrupted sleep patterns

Working over prolonged periods of time under artificial light can mess up with your sleep routine. Being exposed to excessive ultra violet light rays, sabotages melatonin production in your body resulting in disrupted sleep patterns. Lack of adequate sleep can trigger other chronic diseases. Chronic fatigue syndrome is very dangerous to your wellbeing.


  1. Heart related health complications

As mentioned above inadequate sleep can result in acute heart related complications. The body needs to be able to produce enough melatonin to function properly. This hormone plays a significant role in ensuring your good health. It stimulates anti-hypertension in the body system. When that production is disrupted by excessive light you become vulnerable to heart affiliated diseases.

The solution is the same as in issues above: it’s better to use UV-free light sources of warm and neutral tints.



When choosing among modern lighting sources it’s better to stop on LEDs or good old incandescent bulbs if they are still available in your country. At the same time, LEDs can bring you more benefits than just healthcare. They are much more energy efficient and durable than other existing technologies. But even when using LEDs, pay attention to their quality. They should not flicker or emit UV rays.
