Nowadays, humans are not only inclined to live longer, but also they are demanding improvements in quality of life. it may be possible to improve the quality of life of those patients by low cost, easy and A little bit of a complication methods such as dialysis fluid cooling . This study was a clinical trial that randomized, crossover and double-blind. 42 hemodialysis patients were divided into two groups: 20 and 22 patients. Then, the first group received standard hemodialysis (37°c) for four weeks and simultaneously the second group received cold hemodialysis (35°c). In the second four weeks, the type of hemodialysis was changed. During this time, quality of life was assessed three times, before the study, after the completion of the first four weeks and second four weeks with using a short questionnaire of 36 quality of life questions (SF-36).

The results showed that 45.2% of the samples were male and 54.8% were female.. After the first four weeks, the average quality of life in the cold and standard stage was 73.45 and 44.30, and after the second four weeks was 79.83 and 48.51, respectively. This means that cold hemodialysis significantly has improved quality of life based on health (P <0.001). Cold hemodialysis can improve the quality of life based on health in hemodialysis patients.
