Overillumination

Overillumination refers to the excessive use of artificial light, often in environments where natural light would suffice. It is a common issue in many workplaces and homes, and can lead to a variety of health problems, including sleep disorders, headaches, and eye strain. Overillumination is also associated with waste of energy and light pollution.

Causes

Overillumination can be caused by a number of factors. These include the use of lighting fixtures that emit too much light, the improper placement of lighting fixtures, and the use of light sources that are too bright for the task at hand. In many cases, overillumination is the result of poor lighting design.

Health effects

Overillumination can have a number of negative health effects. These include:

• Sleep disorders: Exposure to excessive artificial light can disrupt the body's circadian rhythm, leading to sleep disorders such as insomnia.
• Headaches: Overillumination can cause eye strain, which can in turn lead to headaches.
• Eye strain: The eyes can become strained and fatigued when exposed to too much light, especially when it is artificial light.

Environmental impact

Overillumination is not just a health issue; it also has a significant environmental impact. It contributes to light pollution, which can disrupt ecosystems and wildlife. It also leads to the unnecessary consumption of energy, contributing to climate change.

Prevention

There are several ways to prevent overillumination. These include using lighting controls such as dimmers and timers, using energy-efficient lighting such as LED lights, and making use of natural light whenever possible. Good lighting design can also help to prevent overillumination.
