The impact of lighting on health: how to choose the right lamps for work and play

The impact of lighting on health: general principles

Lighting plays an important role in our health and well-being. It not only affects our eyesight, but also our mood, energy levels, ability to concentrate, and even the quality of sleep. It is important to remember that lighting can have both positive and negative effects, depending on its type and application.

Improper lighting can cause eye strain, headaches, insomnia, and mood deterioration. While proper lighting helps improve concentration, increase productivity, and create an atmosphere for relaxation and relaxation. Considering that modern life often involves a lot of time indoors, a competent choice of lamps becomes an essential element of a healthy lifestyle.

How does lighting affect vision and concentration

Lighting has a direct effect on vision, especially when reading for a long time or working with a computer. Lack of lighting causes eye strain, fatigue, and headaches, while too much light can overload the optic nerves. For comfortable perception of information and protection of vision, it is necessary to use lighting that will create an optimal balance between brightness and softness.

In addition, lighting affects concentration. Insufficient lighting can reduce the ability to concentrate, as the eyes will get tired faster, which leads to a decrease in productivity. In turn, proper lighting helps to improve attention and maintain high energy levels throughout the day. For this purpose, it is recommended to use brightness-controlled lighting, which can be adjusted depending on the time of day and the task being performed.

Sleep lighting: how to choose bedroom lamps

The quality of sleep is directly related to the lighting in the bedroom. Bright or cold lighting before bedtime can disrupt the production of melatonin, a hormone that regulates sleep and wakefulness cycles. This leads to insomnia and a decrease in the quality of rest. For the bedroom, it is recommended to choose soft lighting with a warm white or yellow shade. The best option would be lamps with adjustable brightness, allowing you to create an atmosphere of relaxation before bedtime. 

It is also important to avoid using bright light sources such as chandeliers or ceiling lights with cold light. Instead, you can use nightlights, lamps with shades, or floor lamps with soft lights that will not interfere with bedtime preparation. Using cold and bright light sources in the morning or during the day can help regulate the body’s circadian rhythms, ensuring a more active awakening and better productivity.

The effect of the color of light on mood and emotional state

The color of light has a strong influence on our psycho-emotional state. For example, cold light (blue spectrum) can stimulate mental activity and alertness, while warm light (yellow and orange shades) promotes relaxation and improves mood. For work or study, when high concentration is required, it is better to use lamps with cold white light. This will increase the level of vigor and concentration. On the contrary, for relaxation, especially in the evening, it is better to choose warm light, which helps to relax, reduce stress and prepare for sleep.

The brightness and temperature of the light are important not only for the physical condition, but also for the emotional background. The wrong choice of lighting can cause irritability, fatigue, and a bad mood. Therefore, it is important to ensure that the lighting in different areas of the house corresponds to their purpose and time of day.

How to choose lighting for your workspace

For work and study areas, the most important aspect is to provide good lighting, which helps to focus and work in a comfortable environment. Choosing the right lamp for a desktop or shared workspace helps to increase productivity and reduce eye fatigue. To work with documents or use a computer, you need bright, but not blinding lighting. Luminaires with adjustable brightness are suitable, which can be adjusted depending on the time of day and the type of work performed. Table lamps with cold white light are optimal for concentration at work, while soft warm lighting may be more suitable for creative activities, such as drawing.

It is important that the light does not create shadows in the workplace and does not overload the eyesight. The best option is to combine the main lighting (ceiling or built—in fixtures) and spot lighting (table lamps or floor lamps).

Lighting for leisure and entertainment: the impact on leisure and recreation

Lighting plays a crucial role in setting the atmosphere for relaxation and entertainment. Proper lighting not only enhances our comfort but also influences our perception of space and our overall sense of relaxation. For spaces dedicated to recreation, such as living rooms or home theaters, the right lighting is essential.

  • Soft, diffused lighting: For relaxation areas like a living room or cinema, it is recommended to use soft, diffused lighting that doesn’t distract from the main activity, such as watching TV or socializing with friends. This type of lighting helps maintain a calm, soothing atmosphere without causing glare or discomfort.
  • Warm light and decorative elements: To create a cozy, inviting atmosphere, lamps with warm light can be used. Adding decorative lighting elements, such as illuminated shelves or plants, can further enhance the ambiance and make the space feel more welcoming and comfortable.
  • Directional lighting for emphasis: If there’s a need to highlight specific interior elements, directional lighting is ideal. Spotlights, for example, can be used to focus light on particular areas or objects, creating visual accents that add depth and enhance the overall atmosphere.
  • Brighter lighting for outdoor activities: For activities that require more focus, such as reading, playing sports, or engaging in hobbies, brighter lighting is necessary to ensure clarity and visibility. On the other hand, soft, subdued lighting works best for relaxing activities like watching movies or unwinding after a long day.
