Lighting can be too bright or too dim (Wickens et al. d1998Bridger, 1995). Bright lights can interfere with the ability to read displays effectively, and the homemade glare-reducing shade is still to be found. Continuous bright lighting has an adverse effect on patients. Dim lighting obviously can interfere with the ability to observe unlit or inadequately lit displays or to detect other adverse medical device or patient situations. 

 

Noise pollution has two components. One is the direct effect of environmental noise on the ability to hear or distinguish important sounds emanating from medical devices, or even from patients. As discussed above, distinguishing significant device sounds, such as alarms, can be difficult even under ideal conditions and is surely degraded by excessive noise. The ue  second component of noise pollution is its generally disturbing nature, at least to some people, including both staff and patients. Annoyed people are not likely to perform at their best, and therefore a particular real environment might not produce the same level of performance as other actual or simulated environments and there are other pollution also which harm enviroment and it also demend as not to do it no ..
