Introduction:
The role of ultraviolet radiation (UVR) in processes occurring in ecosystem is significant, and the effects of its actions on human health are both positive and negative. UV radiation mainly affects the eyesight and skin. Prolonged exposure of the eyes to ultraviolet radiation, especially without protection can lead to serious diseases. On the other hand, insufficient exposure to UVR may seem as a serious public health issue.

Aim:
The aim of this paper is to present health advantages that comes from preventive dose of solar radiation with an overview of their mechanisms of action.

Material and methods:
This narrative review summarizes 36 peer-reviewed studies on vitamin D, sunlight exposure, and health outcomes, identified in PubMed, Scopus, and Google Scholar from 2002 to 2024 through screening of titles, abstracts, and full texts.

Results and Discussion:
Current recommendations for sun protection often emphasize avoiding exposure, but this approach can lead to vitamin D deficiencies and other health issues. It is important to remember that the need for UVR exposure is individual and depends on many factors, such as skin color, geographical location, season, or the type of work one does. Therefore, it is essential to find a balance between the benefits and risks associated with UV radiation exposure. In summary, sunlight plays a key role in maintaining proper health.

Conclusions:
To reap the maximum benefits, it is important to find a balance between protecting oneself from its harmful effects and ensuring an adequate amount of exposure, which is necessary for vitamin D production and overall well-being.
