Background: This study was carried out on individuals who constantly use Blow/Hair- dryers in Hairdressing saloons. We have investigated the possible effects of electromagnetic fields. Method: In the study, 32 subjects selected randomly (mean age:24±6) were divided into two groups:Group 1(n=16, 8 males and 8 females using Blow-dryers) as experimental group; and Group 2 (n=16, 8 males and 8 females never using Blow-dryers) as control group. Total Antioxidant Capacity (TAOC) mmol Trolox Eqv/L and Total Oxidant Stres (TOS)μmol H2 O2 Eqv/L levels of the sera taken from the subjects were measured by an autoanalyzer. Statistical analyses of the data obtained were performed by using SPSS 15.0 Windows Package Program. Results: In the study, TAOC and TOS values measured for males and females in both groups were compared separately by taking the same-genders into consideration. TAOC levels for males in control group were measured as mean±std= 0.72±0.05, for males in experimental group as mean±std=0.49±0.07, p < 0.0001. TOS levels for males in control group were found as mean±std=9.92±1.5, for males in experimental group as 6.77±1.5, p < 0.001. TOS levels for females in control group were found as mean±std=0.58±0.08, for females in experimental group as mean±std=0.40±0.05, p < 0.0001. In the study, it was seen that TAOC and TOS values of individuals who use constantly blow/hair dryers in hairdressing saloons and who are exposed to electromagnetic field varied significantly. Conclusion: It is concluded that radiation plays a significant role in revealing these molecules that play a part in the etiopathogenesis of many diseases, and thus preventive measures should be strictly taken, and exposure time should be taken under control through a limitation in workers
