by Dr Ubaid Khan (MD) 2023



Ina world where depression rates are rising and everyone is unhappy with their life course, it is essential to inculcate things that bring happiness and joy. It becomes inevitable for sick individuals to feel more depressed and lonelier due to their condition. 


Many patients are admitted to hospitals daily, but most of them desire to be treated at home due to most hospitals' sad and cold environments. The same can be said for children admitted to such hospitals, who become very cranky, which does not give them enough room to rest and recover properly. 


A great way to handle the stressful environment of a hospital is by introducing fun activities, especially for the kids, so that they do not dread their hospital stay. Many hospitals have started 'clown care programs.' The problem that came with this initiative was that clowns would be available once a week or maybe once a month.       _cc781905-5cde-3194-bb3b- 136bad5cf58d_   _cc781905-5cde-3194 -bb3b-136bad5cf58d_       _cc78190 5-5cde-3194-bb3b-136bad5cf58d_   _cc781905 -5cde-3194-bb3b-136bad5cf58d_     _cc781905-5cde-3194-bb3b-136bad5cf58d _   _cc781905-5cde-3194- bb3b-136bad5cf58d_       _cc78190 5-5cde-3194-bb3b-136bad5cf58d_   _cc781905- 5cde-3194-bb3b-136bad5cf58d_     _cc781905-5cde-3194-bb3b-136bad5cf58d _   _cc781905-5cde-3194-bb3b -136bad5cf58d_       _cc781905-5c de-3194-bb3b-136bad5cf58d_   _cc781905-5cde -3194-bb3b-136bad5cf58d_       _cc 781905-5cde-3194-bb3b-136bad5cf58d_ _cc781905-5cde-3194-bb3b- 136bad5cf58d_


These programs consist of hospital clowns entering the pediatric department and making sure to help kids smile and play with them. There are also certain humor rooms built in hospitals that have fun activities, books, posters, comic books, and videos to make children happy and stress-free during their stay at the hospital. The biggest reason hospitals focus on programs to make sick children smile and laugh about their day is the benefits that it brings about during recovery from any disease. [1]

Therefore, kids staying in hospitals can significantly improve their health status if they laugh happily during their hospital stays.
