Preferred Abstract (Original):
The study population consisted of 237 children aged 5-6 years in Jenin city. The arterial blood pressure (systolic and diastolic), heart pulserate, oxygen saturation in blood and tympanic temperature weremeasured before and after exposure to light intensity levels for four hourscontinuously. The light intensity levels were (0 - 60), (400 - 600) and(1320 - 1500) lux. The background light was (400 - 600) lux for allselected schools, which is considered to be normal or accepted lightintensity level. Strong positive correlation (Pearson CorrelationCoefficient) was found to be R > 0.659 between light intensity levels andall of the arterial blood pressure (systolic and diastolic), heart pulse rate,blood oxygen saturation and tympanic temperature in the selected school.In addition, P-value between the dependent and independent variableswas found to be zero. Finally, the study concludes that there is an effectof the light intensity levels on arterial blood pressure (systolic anddiastolic), heart pulse rate, oxygen saturation in blood and tympanictemperature of schools’ children.
