Abstract
Background: Previous reports showed that infrared radiation (IR) involved in photoaging, photocarcinogenesis,
free radicals’ production, and depletion of bone marrow cells. Beneficial effects of moderate exposure to infrared
lamp have been itemized to include enhancement of blood circulation, relief from muscular pain, and wound
healing acceleration with scarce information on biological effects when it is overexposed. Therefore, there is a
need to investigate the possibility of its overexposure on the biological system, especially blood parameters. Aim: This
study was aimed to determine the biological effects of overexposure to radiation from infrared lamp on blood
parameters. Materials and Methods: Infrared lamp of 100 W acts as a source of the IR. Twenty male healthy
Wistar rats of the age range between 10 and 12 weeks and weigh between 100 and 250 g were studied. All the
animals studied also acts as a control group with their blood samples taken and recorded as initial counting values.
The animals were later divided into three groups: A, B, and C according to their hours of exposure according to
their weight. Animals in Groups A, B, and C were exposed to IR for 1, 3, and 5 h, respectively. Blood samples of
each animal in the group were taken 24, 48, and 96 h after exposure. The total number of erythrocytes, leukocytes,
lymphocyte, and neutrophils were counted and compared with the initial samples. Results: The results revealed
that packed cell volume, white blood cells, and lymphocytes of all the exposed animals averagely decreased
by 17.4%, 17.5%, and 11.3%, respectively, whereas neutrophil increased by 19.0% after exposure to infrared.
Conclusion: This study established that overexposure to radiation from infrared lamp affects hematological
parameters.
