Effects of lack of natural light Many experts say that the lack of natural light may make negative effects on people in the workplace. I completely agree with this statement. Firstly, the lack of natural light may be considered as one of the reason for decrease performances, because workers become tired much quicker by using artificial lighting. Moreover the chance to make mistakes is higher compare with normal conditions. For instance, it is widely known how important the right lighting is for grocery shops, perfume shops and clothes shops. Secondly, the artificial lighting can lead to a deterioration of health by and large and to different problems with eyes in particular. Besides high frequency blinking of the artificial lamps often is a cause for people to have a headache. In conclusion, I would like to say that companies have to pay much attention on the problem of lack of natural lighting in order to decrease the negative effects.
