The Effect of 4-7-8 Breathing Exercise Training on Sleep Quality

Participants in the intervention group will be taught 4-7-8 breathing exercises collectively, and the training will be repeated on specified days (twice a week for a total of 4 weeks). During the training, it will be checked whether each participant in the intervention group can perform the breathing exercise correctly and feedback will be given. Participants who fail to implement the exercise will be excluded from the study. 4-7-8 breathing exercise training, prepared in accordance with the literature, will be given by the assistant researcher who has training and certification in breathing exercises. Training will be planned in an empty classroom, for approximately 20 minutes and at the students' end time. Thus, educational activities in the institution will not be disrupted.
