Does Artificial Lighting Affect HealthDoes Artificial Lighting Affect Health

Lighting is our daily necessity. It is not only our most commonly used lighting tool but also one of the most important ways for human beings to obtain energy.

Artificial lighting regulates the body’s functions and improves the quality of sleep. It can also improve appetite and keep people in a good mood and physical strength. However, too much light can cause damage to the eyes and various eye diseases.

Likewise, because plants indoors also suffer from a lack of light due to climate and geographic location, sunlight artificial light is also an important way for them to obtain energy.

Read on for an in-depth look at the effects of artificial lighting on humans and plants, and how we should use it properly.

Correct Way to Use

  • You should try to avoid working and studying under strong light. If you need to work and study under strong light (such as before going to bed at night), you should use anti-glare lamps and avoid direct light.
  • Indoor lighting should not be too bright or too dark.
  • It is better to work and study in a well-lit place. If the light is insufficient, turn on your light. Indoor artificial light for plants is very effective for plant growth.
  • The light should avoid direct exposure to the eyes, so as to avoid eye fatigue and decreased vision.

In addition, attention should be paid to avoiding turning on the lights when watching TV and playing on mobile phones at night.

Avoid Looking Directly at Artificial Lighting

Direct light exposure to the eyes can cause vision loss, headache, and so on. Therefore, we should pay attention to protecting our eyes when using lamps and lanterns, and avoid looking directly at lamps and lanterns.

Adopt eye-protection lighting to protect our eyes well from unnecessary damage. When gardening indoors, using plant lights LED and wearing glasses are the best ways to protect the eyes.

It is appropriate to choose white or light-colored lamps under normal circumstances. This is because the light shines on white objects can make the light off-color

Avoid Too Much Lighting

Some low technical level of lamps leads to uneven indoor illumination and improper use of light sources. It is not advisable to place too many lights in the room.

If you have multiple lighting fixtures in your room, you should first use the main light to determine the main light source and auxiliary light source and adjust them. For local lighting, lamps with eye protection functions, such as table lamps and floor lamps, should be selected.

If you use a desk lamp for lighting, you should put a lamp about 30cm away from the desktop to protect your eyesight. The same to growing plants with artificial light, a certain distance needs to be kept between the two as well.

Choose the Right Artificial Lighting

For bedrooms and study rooms that need to work for a long time, lamps without stroboscopic components are an ideal choice. Strokes can cause damage to the eyes. When we are watching TV, the screen and display of the TV will emit stroboscopic light. The longer people watch TV, the greater the damage.

Therefore, you should choose those lamps with small frequency and low flicker. The kitchen, a space prone to grease and smoke, is the perfect choice for waterproof, grease-proof fixtures. Waterproof lights for plants indoors are also a must for gardening enthusiasts.

Artificial Lighting Effect on Plants

The above-mentioned artificial light affects humans, which is designed to affect plants. Next, we briefly talk about its impact of it on plants.

Light can promote the differentiation of plant tissues, which is conducive to the formation of tubular cells in the vascular bundle of the hypocotyl. Therefore, under sufficient light conditions, the stem of the sapling has well-developed xylem. How do we use the right lights for plants?

Light Requirements of Plants

Plants require different lengths of light at different times of the year.

  • During the seedling/growth stage, it is recommended that plants be irradiated for 16 hours and rest for 8 hours.
  • In the nutritional stage, the patient was irradiated for 18 hours and rested for 6 hours.
  • At the flowering stage, they were irradiated for 12 hours and rested for 12 hours.

Avoid Too Much Light Time

  • The growth of plants is complicated, and the light required for each plant to each growth stage is different.
  • If it is a plant in the growing period, generally speaking, when there is a certain amount of sunlight, it will take 5 hours to fill the light with artificial light for indoor plants, and it will take about 10 hours on rainy days, and not only about 12 hours when there is no sunlight at all.
  • Because plants also need to rest at night and grow again, generally, the lighting time at night should not be too long, and sufficient time should be reserved.

Choose the Right Artificial Lighting for Indoor Plants

  • When determining the size of the required plant lamp, consider the number of plants to be covered.
  • Leave enough space to prevent them from touching other objects in the room, which will affect heat dissipation and cause potential safety hazards.
  • Considering the types of plants planted, the irradiation of existing natural light, and the location of plants, choose the appropriate artificial lights for plants.
  • Choose which is easy to install, disassemble and control, which can greatly save the planting time and control the plant growth process.


For the sake of our health, we should use artificial lighting as correctly as possible to reduce its harm to us. Different plants require different light. It is also necessary to pay attention to the controlling the lighting to protect every plant in the greenhouse.
