One of the most important events of life is the transition from work to retirement. It might have negative and positive effects on health mentally and physically based on the lifestyles, and leisure activities adopted by the people. After retirement, most of the properties gained through the pre-retirement area might change and even be lost such as the social role. If the transition period is hard to get through, it might result in feeling lost, ineffective, and isolated. The current paper aims to present a literature review, focusing on different studies conducted in various countries, to get a general idea of how the transition period is going with outcomes. In addition, the article provides insight into the impact of leisure on adult well-being through a mixed comparison of cross-sectional studies on the topic. The paper also highlights the importance of retirement education and planning both before and after retirement, as recent findings on older adults suggest that trends in how to spend leisure time differently than in the past are changing. Therefore, further research is needed to be conducted to understand the impact of new leisure activities on well-being in later adulthood
