Ultraviolet (UV) rays from the sun can be beneficial in some ways, such as helping the body synthesize vitamin D. However, unprotected exposure to UV rays can also be damaging to the skin, eyes, and immune system. Heredity and environmental factors can also contribute to the effects of sun exposure.The most common consequence of sun exposure is sunburn, which is caused by UV light damaging the skin. As you age, it becomes more difficult for your skin to repair itself from this damage.
Over time, UV rays can affect the skin and underlying connective tissue, leading to wrinkles and lines. Sunlight has both positive and negative effects on the human body. While it can cause skin burns and increase the risk of cancer in the long term, it is also necessary for vitamin D synthesis in the skin. Therefore, it is important to find a balance between healthy exposure to the sun and dangerous overexposure. The effect of sun exposure on the body is independent of vitamin D level and is instead mediated by the release of nitric oxide from the skin after exposure to ultraviolet light. As an expert in sun safety, I recommend taking precautions to protect yourself from harmful UV rays. Wear sunscreen with an SPF of at least 30 when outdoors, even on cloudy days.
Wear protective clothing such as hats and sunglasses when possible. Avoid direct sunlight during peak hours (10am-4pm) when UV rays are strongest. And lastly, be aware of your environment and any changes in your skin that could indicate overexposure.
