Vitamin D deficiency has become a prevalent public health concern worldwide, with implications ranging from impaired bone health to compromised immune function. Sun therapy (heliotherapy) has been recognized as a natural method for managing vitamin D deficiency due to the ability of ultraviolet B (UVB) radiation to stimulate the synthesis of vitamin D in the skin. This paper explores the mechanism, health benefits, challenges, and guidelines for safe sun exposure as a treatment for vitamin D deficiency. We review the existing literature and provide empirical data that support the therapeutic role of heliotherapy in addressing vitamin D deficiency, while acknowledging the risks associated with overexposure. By examining authentic data and research findings, we aim to highlight the effectiveness of heliotherapy as an alternative or complementary approach to supplementation and dietary intake in vitamin D management.
