Dr. Venkata Sujatha Vellanki, a leading fertility specialist at Oasis Fertility, explains: “For the body to synthesise vitamin D, moderate sun exposure is necessary, but finding the ideal balance is important because both insufficiency and excessive exposure have risks. The relationship between sun exposure and reproductive health is complex—it’s a double-edged sword.” Both too little and too much vitamin D can negatively impact fertility. While deficiency has been linked to hormonal imbalances and reduced reproductive function, overexposure can increase the risk of skin damage and other health concerns. Sunlight remains the most natural and effective way for the body to produce vitamin D. When the skin is exposed to ultraviolet B (UVB) rays, it triggers vitamin D synthesis. The ideal time for sun exposure is midday, as the sun’s rays are at their strongest. However, the recommended duration varies based on skin type: Longer exposure is necessary for individuals with darker skin, as higher melanin levels reduce vitamin D production. However, prolonged sun exposure can lead to skin damage, making it essential to find the right balance. Vitamin D plays a critical role in reproductive health for both men and women. It regulates hormones, improves egg quality in women, and enhances sperm motility in men. Studies suggest that vitamin D deficiency can contribute to fertility challenges such as irregular ovulation in women and poor sperm quality in men. Dr. Prinka Bajaj, Senior Consultant Fertility Specialist at Oasis Fertility, emphasises the importance of supplementation for individuals in low-sunlight regions: “Supplements can assist people who live in areas with little sunlight in maintaining healthy levels of vitamin D. However, excessive sun exposure raises the risk of skin cancer. Skin cells can be harmed by excessive UV radiation exposure, increasing the risk of premature ageing and skin diseases.” To protect against UV damage, applying sunscreen after the recommended sun exposure period is highly advised. The key to maximising the benefits of vitamin D without the risks lies in a balanced approach. Moderate sun exposure, a nutrient-rich diet, and supplements when necessary can help maintain optimal vitamin D levels. Individuals concerned about their vitamin D levels should consider consulting a healthcare professional for guidance on safe sun exposure and supplementation. In conclusion, while vitamin D is essential for fertility and overall well-being, mindful sun exposure is critical. Striking the right balance ensures the benefits of this vital nutrient without compromising health.
