For 7 days, they were asked to watch ASMR videos for 20-30 minutes every evening at 22:00 before going to bed. The videos were downloaded to the student's computer or phone in advance, the student was asked to switch his/her phone to airplane mode to block the stimuli during the viewing, to watch these videos with headphones, to reduce the sounds in the room as much as possible, to lie on his/her bed and to wear comfortable clothes.

no intervention

We used 7 ASMR videos published on the most watched ASMR channel on the YouTube platform, in which applications such as hair combing, brushing, massaging the head are applied sequentially and repeatedly, and there is no speech.

PUKI was accepted in determining sleep quality, and in 1989 and its validity and reliability were determined (Cronbach's alpha=0.80). In our country, the validity and reliability study was carried out by Ağargün et al. (16) and the Cronbach alpha value of the scale was found to be 0.80. The scale is a four-point Likert type and contains a total of 24 questions; subjective sleep quality (component 1), sleep latency (component 2), sleep duration (component 3), habitual sleep efficiency (component 4), sleep disturbance (component 5), use of sleeping pills (component 6) and daytime dysfunction (component 3) 7) consists of 7 components. The sum of the seven component scores gives the total PUKI score. The response of each is scored between 0-3 according to symptom frequency. The total score has a value between 0-21.

State - Trait Anxiety Inventory-STAI. It was developed by Spielberger et al. (1970). The scale consists of two parts: the State Anxiety Inventory and Trait Anxiety Inventory. The State Anxiety Inventory determines how the individual feels at a certain moment and under certain conditions, and the Trait Anxiety Inventory determines how the individual feels regardless of the situation and conditions. Each scale contains two types of statements with 20 items. In the state anxiety scale, the responses were evaluated with a 4-point scale (never, a little, a lot, completely). In the trait anxiety scale, the answers of the participants were measured with a 4-point scale (never, sometimes, very often, almost always). The total score value obtained from both scales varies between 20 and 80. A high score indicates a high level of anxiety and a low score indicates a low level of anxiety.
