As preparations for the upcoming school year, set to begin on September 1st, are in full swing, parents and children are eagerly organizing their notebooks, books, and new pencil cases. The children’s rooms are also undergoing changes and adjustments in anticipation of moving to first grade, middle school, or high school.

One important factor that affects children's alertness and concentration is the proper lighting in their room. Dudi Kesselsi, head of the lighting division at the electrical and lighting equipment chain Erco' provides a short guide for parents.

Firstly, focus on the intensity of the lighting. The healthiest light for the body is sunlight; therefore, it is highly recommended that the room lighting be as close as possible to natural daylight. It’s also crucial to ensure even light distribution throughout the room. Full lighting levels help the body relax and maintain good energy levels.

In addition to the room’s main lighting, it's important to prepare the area designated for study with specific lighting. For computer areas, ensure soft lighting with low to medium intensity. Since computers emit blue light, which disrupts melatonin secretion, it is recommended to use warm lighting with a broad light spectrum during the day to counteract the negative effects of blue light. For tasks requiring attention to small details, like crafts or drawing, stronger lighting is preferable.

Furthermore, it’s important to consider the direction of the light, ensuring it comes from above rather than directly into the eyes to avoid glare, fatigue, and headaches. For example, when sitting in front of a computer screen, make sure the light source isn’t within your direct line of sight.

It’s highly recommended that the light fixture be elongated or have a large surface area for maximum light distribution. The more diffused the light, the less likely it is to create sharp shadows that strain the eyes over time.

Additionally, strive to ensure that the entire area within your field of vision is illuminated with similar intensity. If the eye perceives a high contrast between a well-lit area and a dark one, it will tire more quickly. For example, if your desk is well-lit but the wall in front of you is very dark, the high contrast will contribute to eye strain.

If possible, divide the lighting on the desk into two separate sources: one that provides soft, low to medium intensity light, and another that offers stronger lighting for specific areas and short periods. For instance, a fixed ceiling light that illuminates the entire workspace, combined with a desk lamp that lights a smaller area when needed.

Finally, adjust the desk lighting to the child’s changing needs. When the child is in lower grades, ensure the lighting is positioned to match their height and help them easily see their study materials on the desk. As they grow, adjust the study area lighting in the room according to their height and evolving needs.
