Aim: The study aims to examine the effect of progressive relaxation exercises administered to nursing students via telenursing on sleep quality after the February 6 earthquake in Turkey.

Materials and Methods: The study was conducted as a randomized controlled study. The study population consisted of first-, second-, and third-year nursing students enrolled in the nursing departments of two universities located in eastern Turkey, who were residing in one of the 11 cities affected by the earthquake during the February 6 Turkey earthquake. The sample included 86 students (40 experimental, 46 control). While the control group received no intervention, the experimental group received progressive relaxation exercises for 20 minutes every night for 4 weeks, 1 hour before the routine bedtime (or the time they planned to go to sleep) by making a video call (via Google Meet application) with the student. Data were collected using a personal information form and the Pittsburgh Sleep Quality Scale. Descriptive statistical methods (frequency, percentage, arithmetic mean, standard deviation), independent groups t-test, and paired t-test were used to evaluate the data.

Conclusion: The research results can showed that progressive relaxation exercises could be an effective intervention in improving sleep quality after an earthquake. Additionally, conducting these exercises via telenursing could contribute significantly to the sustainability and control of the intervention.

• If the students have any pre-sleep habits (using aromatic oil, massage, listening to music, etc.) that they routinely practice and that may affect the results of the study, they will be asked not to do so for 6 weeks.
• A video call is made with the students.
• The procedure is explained to the patient and any questions are answered or concerns are addressed.
• If possible, the patient is asked to move to a ventilated room away from noise so that the procedure can be performed comfortably and not interrupted.
• Procedure
• It is explained to the individual that the procedure can be done sitting or lying down and he/she is asked to release his/her muscles and take a comfortable position.
• The individual is asked to close his/her eyes and focus only on his/her body.
• For 5 seconds, the individual is asked to take a slow deep breath.
• He/she is asked to breathe out in a controlled manner in 3-4 seconds.
• The process of taking a deep breath in 5 seconds and giving it back in 3-4 seconds is repeated 3 times.
• While breathing, the individual is asked to squeeze his/her forehead muscles by raising his/her eyebrows as high as possible at the same time.
• After 10 seconds of tightening the forehead muscles, the patient is asked to slowly lower his/her eyebrows and slowly relax and release the forehead muscles while exhaling. He/she is encouraged to feel the relaxation in the forehead muscles.
• The individual is asked to take a deep breath, close his/her eyes tightly and squeeze the muscles around the eyes.
• After 10 seconds of tightening the muscles around the eyes, he/she is asked to slowly relax and release the muscles around the eyes while exhaling. With muscle

Inclusion Criteria:

• The study included students who were in one of the 11 cities affected by the Turkey earthquake,
• did not have a medical diagnosis related to sleep disorders,
• were not using any sleep medications or long-acting treatments,
• had access to necessary equipment for telenursing such as the internet, computer, or phone,
• were enrolled in the first, second, or third year of the nursing program.

Exclusion Criteria:

• The fourth-grade nursing students were excluded from the study because they undergo internship training and work night shifts,
• which may affect their sleep patterns and quality and create a difference between them and other students.
• Students with any diagnosis related to sleep and those with any psychiatric diagnosis were also excluded.

Participants' data were collected for research purposes only according to the ethical principle of condentiality and protection. Therefore, it cannot be shared.
