title: Rosacea and exposure to tandoor heat: Is there an association?
abstract: BACKGROUND
  Particularly in eastern and southeastern regions of Turkey, women use tandoor ovens to bake bread and as a result are exposed to excessive heat. Exposure to heat for long periods may lead to the initiation or exacerbation of rosacea.
  
  
  OBJECTIVE
  The aim of this study was to investigate whether there is a relationship between exposure to heat from a tandoor and rosacea.
  
  
  METHODS
  A total of 350 female patients with various dermatological diseases were included in this study. These patients were divided into two groups comprising a control group and a group of tandoor users. Subjects in both the control and tandoor-user groups were screened to identify clinical and other characteristics, and symptoms and findings of rosacea and other dermatological disorders.
  
  
  RESULTS
  The frequency of rosacea was significantly (P < 0.001) higher and that of acne markedly (P < 0.001) lower in the tandoor-user group than in the control group. Incidences of temporary and persistent types of erythema and telangiectasia, which are considered to be among the symptoms and findings of rosacea, were also significantly (P < 0.001) higher in the tandoor-user group than the control group. Frequencies of asthma and ex-smoker status differed significantly (P < 0.001 and P < 0.002, respectively) between the tandoor-user and control groups. Furthermore, the period of exposure to tandoor heat was positively correlated with the frequency of telangiectasia (r = 0.321, P < 0.01).
  
  
  CONCLUSIONS
  Our study revealed a strong association between exposure to tandoor heat and rosacea. Further studies including higher numbers of patients are required to confirm our results.
