Book Review: Our Conflicted Relationship with the Sun

The book In Defense of Sunlight by Nina Jablonski argues that humans have an often contradictory relationship with the Sun.

While sunlight is essential for life—providing vitamin D, regulating circadian rhythms, and boosting mental health—modern society has developed a complex, sometimes fearful attitude toward it.

Jablonski, a biological anthropologist at Pennsylvania State University, examines how cultural, scientific, and economic factors shape this relationship.

The book highlights how misinformation, such as exaggerated fears of skin cancer, has led to widespread avoidance of sunlight, despite its proven benefits.

Jablonski also critiques the sunscreen industry for promoting excessive sun avoidance, which may inadvertently harm public health by contributing to vitamin D deficiencies.
