The study interviewed a number of participants every two years over the course of a six year period about their mental health, finances, employment history and work or retirement life as well as completing a basic mental health questionnaire.
The findings were significant, showing that people who who took a post retirement jobs that were related to their previous careers reported better mental health than those who were fully retired. This was however, not to be the case for those who took on jobs outside their area of expertise, which showed no similar boost.
Experts think that this might be because retirees who take jobs outside their career field might find it difficult to adapt to a totally different working environment and ethos and therefor find the situation stressful.
Also, the results showed that retirees under financial strain are more likely to seek employment in any field of work.
If you continue working once you have retired, often your status and mindset reminds similar to the one you experience during your career and as a result your self esteem and sense of well being will be enhanced.
