Evidence of Benefits

At many of the Laughter Yoga sessions I deliver, I ask participants to complete a before and after questionnaire about how they feel using scores between 1 to 10 (1 being worst and 10 being best) to describe the level that they feel. The results invariably move towards the higher numbers for the ‘after’ questionnaire.

The topics covered are as follows:

Energy level
Stress level (how ‘stress free’ do you feel)
Level of friendship with group members
Level of awareness about your breathing
Level of muscle relaxation
Level of mental relaxation
Ability to laugh without a reason


Over the past 3 years I have collected quite a lot of data that is demonstrating the positive effects of Laughter Yoga.  I changed the wording of the ‘stress’ question in 2016 as I felt the wording was giving opposite ratings to what was evident through the other questions.  Here in the UK, if we put a high number against the stress questions, people associate it as a high level of stress, i.e. feeling at their worst.  Hence my change in the wording.

Here are graphs of the ‘before’ and ‘after’ evaluations from January to December 2017 from a total of 152 participants:

2017 Total Evaluation to December - Before

2017 Total Evaluation to December - After

(These two graphs for 2017 can be seen in more detail here)

These graphs clearly show that in most cases there is a significant ‘push’ towards the higher number scores ‘after’ the Laughter Yoga session.  There are always a few anomalies but then everybody is different and Laughter Yoga doesn’t suit everybody.
