Laughter yoga for nurses The experimental group was divided into three groups as 18-17-16 people. Sessions 1st group Monday-Thursday between 12:00-13:00; 2nd group Tuesday-Friday between 17:00-18:00; The third group was held on Wednesday Saturday between 20:00-21:00.laughter yoga for nurses-Deep breathing exercises Deep breathing exercises (5 minutes), Warm-up exercises (10 minutes) laughter yoga for nurses-Childish games Childish games (10 minutes), Laughter exercises (15 minutes).

Deep breathing exercises (5 minutes) Breathing is held for 4-5 seconds after deep inspiration. While the arms are brought to the normal position, exhale slowly and rhythmically. When expressing after deep inspiration, the lips can be pursed as if whistling or exhaled with laughter.

Warm-up exercises (10 minutes) Rhythm of 1-2, 1-2-3 is added to increase the energy level even more and synchronize the movements of the group. After a few rhythmic clapping movements, another movement is added. Whisking hands left and right. Then an audible rhythm of ho, ho, ha-ha-ha is added to the clapping gesture. Make eye contact with people in the group and smile at them.

Childish games (10 minutes) Childlike games are used to help laugh without reason just like a child. The group is motivated by visualizing these games in their minds, raising the arms up in the form of a "Y" letter, and saying "very good (applause), very good (applause), hey" with palms facing the sky.

In this study, 8 sessions of laughter yoga were applied to the nurses in the experimental group as an intervention, twice a week for 4 weeks. Due to the Covid-19 pandemic; Laughter Yoga sessions were held on the web through the 'ZOOM' program.

For this reason, it is recommended that the laughter yoga sessions be done with a group and that the group should consist of at least five people in order to provide group dynamics. Sessions are planned according to the days and hours that nurses can attend. Sessions 1st group Monday-Thursday between 12:00-13:00; 2nd group Tuesday-Friday between 17:00-18:00; The third group was held on Wednesday-Saturday between 20:00-21:00. The nurses were constantly contacted (whatsapp, phone) to ensure that they attend the sessions regularly and that there is no interruption in the sessions. No experiment was performed on the control group during the study. However, after the research, a 4-week laughter yoga was given to the nurses who wanted it.

In this form prepared by the researchers; There are a total of 9 questions including age, gender, education level, marital status, working year, frequently worked shift, Covid-19 passing and being vaccinated, whether or not he has knowledge about laughter yoga.

The scale, which was created in order to understand how stressful individuals perceive certain events they experience, consists of 14 items, graded in a 5-point Likert type. In the scale, 7 items containing positive statements are reverse scored. The score range of the scale ranges from 0 to 56, and a high score indicates a high level of stress. The internal consistency coefficient of the scale was calculated as 0.84. In this study, the Cronbach alpha internal consistency coefficient was found to be 0.75.

The scale, consisting of 22 items and three sub-dimensions, is in the 5-point Likert type. The sub-dimensions of the scale are emotional exhaustion, depersonalization and personal achievement. Positive statements in the dimension of personal achievement are reverse coded. The high mean score of the emotional exhaustion and depersonalization sub-dimensions and low personal achievement mean scores indicate high burnout. The lowest score that can be obtained from the scale is 0 and the highest score is 88. The Cronhbach Alpha values of the scale were found to be 0.83 for emotional exhaustion, 0.65 for depersonalization and 0.72 for personal achievement.

There are 5 items in the scale, and each item is arranged according to a 7-point answer system. A score between 5-35 can be obtained from the scale. Higher scores indicate higher life satisfaction. The Cronbach Alpha value of the scale is .88. In this study, the Cronbach Alpha coefficient was found to be .87.
