Using too much lighting is of course raising the energy bill unnecessarily. What is another important human reason for not applying too much lighting?

Question

Options

• AIt takes too long to switch them all on and off.
• BToo much lighting can irritate people on a physiological level.
• CToo much lighting generates more heat.

• A
  4% (1)
• B
  85% (23)
• C
  11% (3)

Explanation

Excessive lighting causes physiological discomfort in humans - it can lead to eye strain, headaches, glare sensitivity, and general sensory irritation, making it a legitimate human-centered reason to avoid over-lighting spaces. This falls under the ergonomics and human factors of environmental design, which is why B is correct.

Option A is wrong because the time to switch lights on or off is trivial and not a meaningful reason to limit lighting use. Option C describes a real physical side effect of lighting but is a technical/thermal concern, not a specifically human (physiological or psychological) one - the question asks for a human reason, which points directly to bodily discomfort.

Memory tip: Think of the word irritate - too much light literally irritates the eyes and nervous system. The question keys on "human reason," so anchor your answer to what happens inside the body, not to utility bills or heat output.
