Sunlight has various harmful effects on health, but it also has its benefits, according to Dr. Giulia Enders in her new book 'The Wisdom of the Body'. In an interview with Yle, Enders explains that there is a notable difference in the incidence of certain diseases between northern and southern regions globally. These include autoimmune diseases, colorectal and breast cancer, as well as hypertension. During dark winter months, the same population group experiences more heart attacks compared to summer, suggesting a link to sunlight exposure.

Enders argues that alternative explanations such as genetics, nutrition, or physical activity do not hold up upon closer examination. Therefore, it is highly probable that sunlight provides protection from certain diseases. Professor Antti Auvinen from the University of Tampere echoes similar views, indicating that sunlight's health effects are significant and vary by season.

The insights shared in this article underscore the importance of understanding how sunlight can impact health, especially in different geographical locations. As the conversation around public health continues to evolve, these findings could influence recommendations related to sun exposure, particularly in regions where sunlight is less abundant during parts of the year.
