The questionnaire including demographic characteristics, anthropometrical measurements, questions about physical activity, beverage consumption form, Pittsburgh Sleep Quality Index conducted by face-to-face method. The mean Pittsburgh Sleep Quality score was 5.81±3.36. It was determined that 55.5% of the participants (n=141) n had good sleep quality. Even though the amount of caffeine intake from beverages, consumption number of the caffeinated and stimulant beverages have a negative impact on sleep quality, the level of this impact is low (P<0.05) (r=0.15, 0.15, 0.14). The consumption of coffee without cream deteriorates sleep quality 4.8 times, while ayran (drinkable yogurt, buttermilk) deteriorates sleep quality 2.6 times. It is considered that the lessening in the consumption of ayran, coffee without cream, caffeinated beverages and stimulant beverages could improve quality.
