Laughter Yoga is a complementary therapy that combines fake and genuine laughter with yoga and breathing exercises, including neck and shoulder exercises. It does not involve humor and is non-pharmacological and non-invasive.

A session of laughter yoga lasts about 40 minutes and consists of four sections. The first section includes deep breathing exercises, the second section consists of warm-up exercises, the third section involves childlike games, and the fourth section includes laughter exercises.

The experimental group will consist of 25 participants. Before starting laughter yoga, the "Maslach Burnout Inventory" and the "Nurse Job Stress Scale" will be used to measure burnout and stress levels. Subsequently, a total of eight laughter yoga sessions will be conducted twice a week for one month, after which burnout and stress levels will be measured again using the scales.

The control group will consist of 25 participants, whose burnout and stress levels will be measured only using the "Maslach Burnout Inventory" and the "Nurse Job Stress Scale." No intervention will be applied to the participants.

Laughter yoga reduces stress levels through sessions lasting approximately 40 minutes without any invasive or pharmacological interventions. It regulates breathing, relaxes muscles, stimulates circulation, increases pain thresholds, strengthens immunity, lightens the mind, enhances social relationships, promotes mental balance, and boosts self-esteem, hope, energy, and quality of life. The content of a session includes deep breathing exercises, warm-up exercises, childlike games, and laughter exercises.

The scale consists of 22 items in a 5-point Likert format (0: Never, 1: Very Rarely, 2: Sometimes, 3: Often, 4: Always). It has three dimensions: Emotional Exhaustion (EE, 9 items), Depersonalization (D, 5 items), and Personal Accomplishment Deficiency (PAD, 8 items). EE refers to the emotional overload an individual feels due to their work and is the most significant predictor of burnout. D represents attitudes and behaviors exhibited by the individual without regard to the fact that the people they serve are unique individuals, displaying a lack of emotion. PAD is defined as the inability to cope with problems successfully and feeling insufficient.

Individuals experiencing burnout are expected to have high scores in EE (0-36), D (0-20), and PAD (0-32). The Cronbach Alpha coefficients for the three subdimensions of the scale are 0.83 for emotional exhaustion, 0.65 for depersonalization, and 0.72 for personal accomplishment deficiency.

The original "Nurse Job Stress Scale," developed by Gray-Toft and Anderson, consists of 34 items and seven factors. These factors include: Uncertainty Related to Treatment (8 items = 1,2,3,4,5,6,7,8), Workload (6 items = 9,10,11,12,13,14), Patient Death (5 items = 15,16,17,18,19), Conflict with Physicians (5 items = 20,21,22,23,24), Conflict with Other Nurses (5 items = 25,26,27,28,29), Inadequate Support (3 items = 30,31,32), and Suffering Patient (2 items = 33,34). It is rated using a 4-point Likert system, where (1 point) means never, (2 points) sometimes, (3 points) often, and (4 points) very often. The Cronbach α reliability coefficient of the original scale has been found to be between α = .89 and α = .65 for the subfactors. A high total score indicates that the nurse experiences more frequent periods of stress related to individual stress issues in the physical, psychological, and environmental contexts.
