Objective: To verify the association between cell phone, computer and television use with sleep quality in adults who practice physical exercise. Methodology: This is an observational, cross-sectional and quantitative study. The study sample consisted of 150 individuals, the inclusion criteria were exercise practitioners of both sexes, over 18 years old, who agreed to participate in the study. Those who did not fill out the research form validly were excluded. Two questionnaires were used: Own Questionnaire, with 14 questions and the Pittsburgh Sleep Quality Index (PSQI-BR), with 19 questions. Results: Of the 150 participants, 104 were female, with a median age of 25 years and combine aerobic and resistance exercises (46.66%). 97.33% of individuals use screens before going to bed and only 40 people sleep well. There was a statistically significant association between the practice shift and sleep quality. There was no direct association between cell phone, computer or television use and sleep (p= 0.315), but with time of use (p<0.001). Conclusion: There is no direct association between the use of screens and the quality of sleep, but the time they are exposed and the shift in which they exercise had an influence.
