Burn is a serious trauma that causes acute damage to the skin and subcutaneous tissues due to the effect of heat, electricity, radiation, physical, and chemical substances. Research shows a relationship between burn dressing changes and increased pain, anxiety, and stress. It can also be said that anxiety negatively affects wound healing. This study aimed to determine the effect of Laughter Yoga, a non-drug method, on reducing or completely eliminating pain and anxiety after burn dressing and increasing the level of mental well-being. This study is planned to be conducted in a randomized manner.

The Burn Center will consist of patients receiving treatment at the Burn Clinic. Data will be obtained through the Introductory Information Form, Visual Analogue Scale (VAS), State Anxiety Scale and Warwick Edinburgh Mental Well-Being Scale. Patients who will receive burn dressing will be visited in the clinic before the dressing and will be informed about the study. Sampled individuals will be placed into intervention and control groups using a random number table created with MS Excel software. The average hospital stay of patients is three weeks. Within the scope of the study, laughter yoga will be applied 2 hours after the dressing to the patients who are treated in the burn clinic for three weeks and are included in the intervention group.

For the control group, STAII State Anxiety Scale, Visual Analog Scale (VAS) and Warwick Edinburgh Mental Well-Being Scale levels will be determined in the same periods without any application. The data obtained will be analyzed with appropriate statistical methods using the SPSS for Windows 23.0 program (Statistical Package for the Social Sciences).

• In individuals with 2nd degree burns, the total burn width does not exceed 40%, and in those with 3rd degree burns, the total burn width does not exceed 10%,
• At least 2 days have passed since the burn injury (the inflammatory phase has passed during the wound healing process and is in the proliferation phase),
• Not in the maturation phase according to the wound healing process, No burns in the abdomen and head and neck area (due to preventing the possible negative effects of Laughter Yoga on the specified areas)
• Patients who volunteer to participate in the research will be included in the study.

When laughter yoga studies in the literature are examined, the laughter yoga practitioner is the researcher himself. Therefore, due to the nature of the application method to be used, the patients and the researcher are not considered blind. The evaluator will be considered blind in the analysis of the study.
