Volunteers (n = 200) were analyzed using an "SF-36 Domaln's questionnaire" for mobile phone use history and subjective symptoms (headache, lowering of concentration, physical fatigue, dizziness, nausea, memory loss, discomfort, ear-heating, face-reddening /heating, skin dryness, face itching, eye-hurting, tears dropping, etc.) to look for correlations. The authors preliminarily report an association between mobile phone use for longer than 30 minutes and headache in males (p<0.01) but not for other symptoms. |
