Smiling helps seeing everything from a positive perspective. It is a way of reminding yourself that this difficult time is going to pass. Smiling during difficult times takes alot of optimism and hope. It does not help them resolve their problem but gives a perspective of not seeing as a problem but as a tough time to pass and nothing more. They face problem everyday so they wonβt forget but beating themselves and being sad would add up to the mental stress.
Smiling also subconsciously elevates self esteem when there is a situation where their confidence is in jeopardy everyday.
